elcome to the May issue of ECN magazine. Recent figures filtering through to us here at ECN suggest that, by 2023, as many as 15,000 additional skilled electricians may be required to accommodate forecasted growth. Good news in many respects, as growth of this size certainly points to a healthy landscape for all those involved in the electrical contracting sector; yet, simultaneously, finding the talent to fill these new vacancies will be no mean feat. Worse still, the figures go on to reveal that even with 5,000 new apprentices over the next five years, the industry could still find itself short of up to 10,000 electricians – and that doesn’t even cover typical turnover rates from leavers and retirement. Full details can be found in our news pages, but enticing apprentices and proactively offering apprenticeships will, of course, be critical in meeting this potential skills gap. Ongoing training is also vital, and there’s a belief that installers should not go in to a property just to fix a job, but to make themselves the expert

and be able to advise on additional opportunities. I recently had the pleasure of visiting Resideo over in Berkshire, which – in addition to its home comfort and security solutions – provides extra training for installers that goes above and beyond standard training methods. The company guided me through several of its training sessions, and I got to experience just how it educates attendees – specifically, as it relates to smart home integration and the potential offered by this everexpanding concept. There’s still a feeling that installers may not fully understand all of the parameters that these smart controls can give, but essentially, it’s demand from installers that will shape the smart home landscape in the long-term. Resideo was keen to stress that it’s not just about educating the installer; it’s also about educating the homeowner. More on the continued rise of the smart home in our July issue. Next month’s issue contains the latest of our special supplements, and – this time – we’re focusing on wiring accessories. There’s still time to be involved, so if you’d like your company to be included, please contact my colleague Kelly Byne by emailing kelly@allthingsmedialtd.com Enjoy the issue.

INDUSTRY NEWS ELECTRIUM LAUNCHES NEW PODCAST SERIES Electrium, one of the UK’s largest electrical installation equipment manufacturing and supply companies – home to leading brands such as Crabtree, Wylex and Volex Accessories – has launched a new podcast series. ‘The Electrium Podcast’ will explore the people who make the sector what it is and allow them to tell their stories, while also debating the latest topics and get to the heart of what matters to designers and installers. The first two episodes are already live. In the first episode, Electrium speaks to Gary Hayers and Joe Robinson from Tresham College in Corby, Kettering. Both have been teachers for many years, and have recently found success with their YouTube series. In the debut podcast, they speak to Electrium about creating their video platforms, and the importance of apprenticeships and teaching the future of the electrical industry.

In episode two, Mike Cash, Group Marketing Manager for Electrium, and Simon Rowlinson, Product Manager for Wylex, discuss some of the key questions coming out of the 18th Edition so far. They chat arc fault detection devices, transient overvoltage protection, RCD selection and more.

The Electrium Podcast is available to stream or download on Soundcloud, iTunes and Spotify, and is free of charge. Alternatively, you can listen at Electrium’s website. Electrium, electrium.co.uk/podcast

CERTON OFFERS PAPERLESS DOCUMENT STORAGE

SMART METER OWNERS REPORTING HIGHER BILLS

Electrician, Boyd Goulden, has developed a novel way to help safeguard documents relating to safety around the home. The new concept, CertOn, is a paperless document storage system that allows homeowners to upload and store all of their relevant documentation. But it’s much more than a cloud-based storage system. Through the issue of a unique QR code linked to the property, CertOn allows installers to use their own smartphone or tablet, to read the QR code and access all important documents instantly. The NICEIC registered electrician says the concept will be able to help all tradespeople. He comments, “I cannot begin to tell you how many times I have been astounded at the lack of certification or missing documents I come across at customer sites. Sometimes it can be blatantly negligent of the previous trades not to have given or left the correct certificates with the customer. Or, it could be that the customer has not understood the importance of keeping that information, [so it is] misplaced or lost.” Using an app and QR code, CertOn digitally stores documents such as electrical certificates, gas checks, fire safety, Fensa, building notifications, warranties, and more. Boyd, who runs Rickmansworth-based Complete Finish, says the application can be used by a variety of professionals, including electricians, gas fitters, developers, housing associations, estate/letting agents and landlords. For a property which is having lots of work done and will lead to different trades installing and signingoff certificates or issuing documents at different times, CertOn could provide the ideal solution.

Having a smart meter installed at home very seldom means lower energy bills, according to new survey findings published by leading electrotechnical trade body, ECA. In the ECA’s recent YouGov survey of adults who are eligible for a smart meter, just one in 14 respondents with a smart meter (7%) said that having one had reduced their energy bills, while one in 11 (9%) said bills had increased. This is despite one in four (23%) reporting that the main reason for having a smart meter installed was to reduce their energy bills. Overall, nearly half of respondents (47%) said they were ‘very unlikely’ to have a smart meter installed during the next 12 months, with 20% ‘fairly unlikely’ to do so. Just 5% of respondents said they were ‘very likely’ to do so, with a further 13% ‘fairly likely’ to have one installed in the next year. ECA Energy Advisor, Luke Osborne, comments, “These ECA findings suggest that smart meter users seldom report lower energy bills – which seems at odds with the Government’s ‘save money’ message. Smart meters can play a role in stimulating a shift towards a lower carbon future. However, the Government needs to do far more to incentivise change and explain the benefits of using smart meters if they are to increase consumer confidence and take-up in the near future.” While 61% of smart meter owners reported that they had no issues with their smart meter, almost half (45%) reported they had experienced no benefits in having one. The benefit that came out on top for respondents with a smart meter was more accurate billing (29%), while one in 11 (9%) cited connectivity issues as a problem.

INNOVATION IN UK ELECTRIC HIGHWAYS BMT has joined forces with National Grid Electricity Transmission (NGET), owners of the electricity transmission network in England and Wales, to help the British energy giant plan energy highways of the future by exploring the impact of an increasing number of electric vehicles on our roads. Noel Tomlinson, Transport, Energy and Infrastructure Business Development Manager at BMT says, “We’re extremely proud to have been appointed to work on this innovative research project. It builds on our extensive expertise delivering first-class studies examining how technologies will evolve to meet future requirements across land, air and maritime domains. We look forward to working in close collaboration with NGET’s team to deliver a best in class solution.” Energy highways are normal motorways that have been constructed for energy storage and have electric vehicle chargers integrated into their design. With the number of plug-in electric and hybrid vehicles increasing each year, BMT will work with NGET to carry out an innovative energy highways project. The project will use a number of BMT tools and processes to investigate the infrastructure required to support the electrification, and thereby de-carbonisation, of transport. BMT’s team of specialists will create a series of concept designs, along with providing high level analysis of the performance, risks and opportunities of each energy highway proposal. As part of the work, BMT is also looking into the electrification and charging infrastructure for both naval and commercial shipping sectors. BMT is an independent consultancy providing engineering and technical support to a variety of government and commercial customers.

INDUSTRY NEWS RECOLIGHT WELCOMES NEW DEFRA PROPOSALS WEEE scheme, Recolight, has welcomed new proposals from Defra to make online marketplaces responsible for compliance with producer responsibility legislation. Defra’s consultation to reform the system for waste packaging identifies the “growing problem of noncompliance through online marketplaces”. Research undertaken by Recolight supports this position, with a review of listings on one online marketplace suggesting that 76% of LED lightbulbs, 54% of power tools, and 50% of electric haircare products were not compliant with WEEE legislation. The solution proposed by Defra is to create a new class of “producer”. This would make online marketplaces responsible for the compliance of all products sold through their websites, that are imported into the UK. Commenting on the proposal, Recolight CEO, Nigel Harvey, says, “The Defra proposal will, at last, tackle this major problem. The solution they have come up with is particularly elegant. Producers based inside the UK that sell through online marketplaces continue to take direct responsibility for their products. But where the producer

is based outside the UK, that responsibility would fall upon the online marketplace.” “At a stroke, this would bring product from thousands, or even tens of thousands of producers, predominantly based in China, into compliance. Those producers would not need to individually register with compliance schemes. Instead, product data, already captured by online marketplaces through sales transactions, would be aggregated and submitted as a part of their own compliance process.” “The process would be simple to audit, simple to administer, and effective at capturing a high proportion of non-compliant product. Enforcing UK legislation on a large number of companies based on the other side of the globe is nigh on impossible. Focusing instead on a few online marketplaces could really drive compliance.” The current proposal only relates to the waste packaging legislation, but it seems likely to be incorporated within other producer responsibility legislation, including WEEE and batteries.

TAMLITE SUPPORTING NEW BIQ INITIATIVE Lighting manufacturer, Tamlite Lighting, is supporting a new initiative which aims to put an end to ‘spec breaking’ on construction projects. The Building in Quality (BIQ) tracker is a free to download digital tool which aims to improve the quality of outcomes in the construction industry. It sets up a chain of custody, allowing project teams to track quality on construction projects. Using the tracker, contractors are able to review and record the level of quality considered appropriate for a particular project, and then provide the means to deliver better quality outcomes. It allows clients to demonstrate their commitment to quality and differentiate themselves in the market. It is hoped that the wider adoption of the Quality Tracker will incentivise better quality in buildings, leading to improved human health, safety and wellbeing, whilst boosting the construction industry’s reputation. Tamlite believes that the initiative – which is led by the Royal Institute of British Architects (RIBA), in association with the Chartered Institute of Building (CIOB) and Royal Institution of Chartered Surveyors (RICS) – is vitally important for the reputation of the UK built environment industry. The lighting manufacturer says this initiative will go some way to rebuilding confidence, particularly from a consumer safety perspective. Tamlite Lighting, tamlite.co.uk

EDA AWARDS FOR REXEL

OVER 12,500 ELECTRICIANS NEEDED BY 2023 A new labour market report on the electrotechnical industry has estimated that between 12,500 and 15,000 additional skilled electricians will be needed over the next five years to accommodate forecasted growth. Within this figure, the research suggests that even if an extra 5,000 new apprentices qualified by 2023 (representing a 33% increase), this would still leave a shortfall of 7,500-10,000 electricians needing to be sourced from elsewhere. These workforce predictions are based on meeting demands solely due to sector expansion, and do not cover the additional staff turnover occurring from leavers and retirement. Emerging and future technologies are expected to be major drivers for this increase in skills needs over the next decade, with smart technology, e-mobility and Wi-Fi technology named as the top three forces for change. Other areas that are likely to influence the sector include changes to regulations and public policy, in areas such as energy efficiency and fire safety. Commissioned by The Electrotechnical Skills Partnership (TESP) and co-funded with industry charity, National Electrotechnical Training (NET), the report is the first to provide an in-depth analysis of electrotechnical skills needs in over 10 years. Research specialist, Pye Tait, compiled the report after surveying almost 450 electrotechnical companies, with around 19,000 employees. The report confirmed that apprenticeships are still highly rated across the sector and, based on up-to-date calculations published in this research, there is clear potential for a return on investment for those who recruit apprentices.

There has been cause for celebration at Rexel, after two individuals from the electrical distributor were recognised for their hard work and dedication at the EDA 2019 Education and Training Awards. Fiona Lothian, Branch Manager for Rexel’s Edinburgh West branch, received the EDA Investor in Training Awards 2019; while Dylan Sanudo-Ellison, an apprentice Warehouse Operative from Deeside, was presented with an EDA Learning Achievements Award for an Outstanding Apprentice. The awards recognise industry professionals for commitment and dedication to developing both their professional skills and careers. It is also a chance for the EDA to celebrate those with leadership skills, who work to drive high performance in their teams. As a business, Rexel has continued to invest in its apprenticeship programme, and in late 2018 it began offering apprenticeships directly through the business. This will allow the apprenticeship programme to develop further and support the continued growth of the business and the industry.

TRUSTMARK STRIVING FOR ENERGY EFFICIENCY TrustMark, the Government endorsed quality scheme for tradespeople, has launched a pilot – in partnership with East Sussex Trading Standards – to improve the quality and energy efficiency of rented accommodation within Hastings and its surrounding area. The initiative, ‘Better Homes for Hastings’, launched with an event hosted in partnership with Hastings Borough Council. It brought together private landlords, housing associations, tenants and businesses, including TrustMark registered businesses, in the Hastings area to promote the minimum standards of safety, comfort, health and energy efficiency that these properties should ideally meet. The event not only educated tenants about their rights and encouraged the comfort and health factors in rented accommodation, but also addressed the issue of fuel poverty through the improvement of energy efficiency measures, which is a key concern in this region. Private landlords, housing associations and letting agents also had the opportunity to learn about the incoming regulations relating to energy efficiency standards in rental properties, and the event connected them with reputable businesses and tradespeople to help ensure their properties meet these requirements. Simon Ayers, Chief Executive Officer of TrustMark, says: “Tenants and landlords need to be confident that the tradespeople they employ to carry out any work on their properties meet the required industry standards. By using a TrustMark registered business, they can be sure that the tradespeople have been vetted to ensure levels of technical competency, customer service and trading practices and are in accordance with Government endorsed quality.” The Hastings pilot is part of a series of events designed to help the Government meet ambitious targets about reduced carbon emissions and fuel poverty. A further project is planned for Cornwall during 2019. TrustMark, trustmark.org.uk

COVER STORY

WORK, LEARN AND PLAY WITH VIVE Lutron has been listening to its end-users and has produced a control platform that has simplicity at its heart. Vive is simple to design, to quote, to install, and to program. And in case you have questions or issues, you’ll always have Lutron’s world-class customer service and support to fall back on.

E

Vive systems cover a wide family of products – including sensors, remotes, load controls, and an available software management suite

nergy management sits at the heart of the Vive lighting control system. Vive is specifically designed to combine lighting control strategies to maximise savings, save money and improve sustainability. Vive includes all the tools that are a prerequisite for good energy control. A range of sensing tools provides automatic control of lighting via occupancy sensors and daylight measurement, and the software also allows demand response during times of peak usage. • Light performance is the thing that Lutron has been best known for – the ability to ‘tune’ a space via a sophisticated lighting management system. While some wireless systems are designed to provide the services already described, Lutron hasn’t forgotten its roots. Once the energy management has been sorted and the practicalities of installation have been resolved, it’s the day-to-day functionality that gives a lighting system its worth. The Vive system can be matched to the main control protocols – DALI-2 / 0-10V / Switching and contact closure outputs or BACnet for integration. Programming can be done using any handheld smart device, via the unique Vive wireless hub. • Design flexibility is an increasingly important factor in spatial design. As the needs of a space evolve, a good lighting installation needs to be able to respond to changes. Conventional wired systems are an encumbrance to spatial fluidity. Wireless communication of the type provided by Vive can be reconfigured without any need to physically access the luminaire or reroute any cabling.

• Installation times for the wireless system are reported to be 70% faster than conventional wired systems, and it is scalable. What might start as a single office or executive meeting room can be expanded to an entire department, office floor or a whole building. And the technology is there to encompass a multi-building estate. NET: Vive wireless solutions save you time and money. It offers a multi-strategy approach that accommodates your clients’ budget and performance needs now, and for the future of their building.

Vive by Lutron offers wireless lighting control that works at any scale of operation, from a single room to a multibuilding estate. It can be employed with existing lighting installations as well as new builds, and it can be used to provide fully automated control as well as manual operation.

CONTRACT NEWS LEARNING ENVIRONMENT LIGHTS UP Thorn Lighting has provided the lighting for the new, £12 million Gelliswick Church in Wales Voluntary Controlled (VC) Primary School. The new facility assists Pembrokeshire County Council with its target of providing flexible and adaptable 21st Century learning environments for pupils. Thorn worked closely on the project with consultants, Hoare Lea Cardiff, and M&E contractors, Highadmit Projects in Beddau. The 515-pupil school replaces Hakin Community and Hubberston VC schools, and is one of several new schools which have been built (or are being built) under the 21st Century Schools Programme; a £150 million initiative between Pembrokeshire County Council and the Welsh Government to build state-of-the-art schools.

One of the main requirements of the project was to improve the learning environment, which is key to improving wellbeing and attendance levels, raising standards and providing dedicated facilities for family integration. To create the desired environment, Thorn’s next generation IQ Wave luminaires were chosen for the classrooms and offices. IQ Wave is a smart recessed LED luminaire that focuses on intelligent controls, optics, design and installation, creating a smooth, homogenous illuminance with no visible LED. Low glare

PINACL WINS INTELLIGENT STREET LIGHTING CONTRACT A leading North Wales tech company has won the contract to provide Aberdeen City Council with ‘intelligent’ street lighting. St Asaph-based Pinacl will deliver an initial 3,500 lighting controllers, along with a corresponding LoRaWAN network and lighting configuration management system (CMS). The solution will enable the council to make major savings on its annual street lighting energy consumption and costs, while also delivering operational and maintenance efficiencies. A ‘quick to install’ system, the solution will give Aberdeen City Council complete control of its street lighting network. Through it, the council will be able to intelligently control, dim and monitor light levels via a secure, cloud-based CMS. The solution also seeks to cut maintenance costs with real-time fault monitoring, and by using detailed operational intelligence to improve day-today effectiveness and planning.

Aberdeen has invested in a £9.7million eight year rolling programme of replacing the old, inefficient and expensive street lighting with more efficient and cost-effective LED lighting. The council’s energy costs for street lighting in 2015 were just under £2 million per year. This is expected to be less than £800,000 per year after all the street lighting has been replaced with LED lanterns. The project will deliver over 60% reductions in street lighting electricity bills after completion of the LED replacement project. The new LED lighting gives out a bright, clear light which is easier to the human eye, providing improved safety for pedestrians and clearer pictures for CCTV footage. The replacement LEDs also offer an increased lifetime over the legacy HID sodium lamps (x6) and fluorescent lamps (x4). They are also ‘greener’ and more recyclable (by up to 90%) and do not contain mercury, lead or heavy metal; and emit no UV radiation. Pinacl, pinaclsolutions.com

(UGR 19, <3 000 CD/m2 at 65°) ensures a comfortable ambient light while high efficacy (>100Llm/W) achieves significant energy savings in comparison to traditional light sources. IQ Wave provides excellent lighting quality, high user comfort and a guaranteed communicative working environment. To aid sustainability, Thorn’s Chalice was chosen for the corridors, as it offers a 60% reduction in energy usage when compared to conventional fluorescent downlights.

CONTRACT NEWS REGGIANI BRINGS NEW LIGHT TO OFFICE SPACE A selection of Reggiani’s Yori luminaires have been chosen for use throughout the reception area of the newlyrevamped Davidson House in Reading. The refurbishment was designed to provide the owners with a more distinctive and inviting entrance. Working with dn-a architecture, lighting design firm Light Bureau was given responsibility for the lighting throughout the exterior and ground floor spaces, and specified Reggiani’s Yori fittings with a view to providing a lighting solution that was consistent in intensity and colour. It was also believed that the Yori fittings would enhance the natural wood design and help bring the exterior and interior spaces together.

The external public walkway now incorporates a warm palette of natural materials, including a timber fin design ceiling structure which links the north and south entrances, as well as seamlessly connecting to the central interior space. Reggiani’s dimmable, track-mounted 22W LED large Yori fittings, with a 30-degree beam angle and complete with a recessed honeycomb accessory, were installed between the internal timber fins to create a soft, welcoming

and relaxing atmosphere to the waiting lounge, and also to support visual continuity with the adjacent passageway. With the reception area also containing large floor-toceiling windows to the front of the building, the soft level of lighting complements and provides a perception of depth to the building façade when viewed from the outside.

STATIC WINS WESTFIELD FIRE ALARM CONTRACT

BESPOKE LUMINAIRES RETROFITTED FOR LED ENERGY SAVING Ecolighting UK has provided a retrofit LED lighting solution for Suffolk County Council’s open plan offices. With the council seeking a new lighting solution, but without wishing to fit entirely new luminaires, Ecolighting’s brief was to retrofit existing ceiling surface-mounted luminaires with LED lighting. The attractive circular fittings, mounted on the 600 x 600 ceiling modules, were stripped of their previous fluorescent lighting and control gear and replaced with a bespoke LED panel especially designed and manufactured by Ecolighting. The 350mm diameter panel has 144 LEDs mounted in concentric rings. The panels have a total power consumption of just 28W, and the luminous efficacy of 140 lumens per watt produces 3920 lumens per panel. They have a long life expectancy of 50,000 hours, with a colour temperature of 4000K and colour rendering index of Ra80. Ecolighting, ecolightinguk.com

ENERGYS GROUP WINS NHS LIGHTING TENDERS Energy efficiency solutions provider, Energys Group, has been selected to deliver LED lighting upgrades at a number of NHS Trusts and NHS Foundation Trusts. Based in West Sussex, Energys won the projects – which include the supply and installation of LED technology – following a competitive tender process. The company is approved by the Essentia Framework (for NHS LED lighting) and is also an approved supplier under the YPO Framework. Both frameworks provide a free service to NHS Trusts to support the entire process from bidding for the grant monies, through tendering the work and delivery of the solution. The funding for the LED upgrades has been made available by NHS Improvement, which is set to inject up to £46m of Public Dividend Capital (PDC) to the NHS Energy Efficiency Fund (NEEF), in a bid to drive direct energy efficiency in the NHS. The NHS’s estates teams are motivated by multiple drivers for the lighting upgrades; LED lighting will provide better quality lighting for both patients and staff, as well as reducing maintenance and energy costs, and cutting carbon. Kevin Cox, Managing Director at Energys Group, comments, “The NHS faces a sizable challenge if it is to meet its carbon reduction targets. We are delighted to be part of the solution. Our company has already proven it is capable of handling large-scale, multi-site lighting projects. We believe this experience is why we have now been selected by several NHS trusts to help reduce their carbon and energy bills, as well as deliver a cut to maintenance costs.

KEY ISSUE

THE WORLD SURGES AHEAD The 18th Edition of the Wiring Regulations represents a change of protection for installations, designed especially to increase the level of safety and reduce the risks associated with transient over-voltages. With the changes now in force, Scott Gallagher of Finder looks at the origins of surge protection.

A shocking start In 1752, Benjamin Franklin conducted his revolutionary experiment capturing charges from a mere cloud. An early adopter of health and safety, Franklin was cautious to stand on an insulator, keeping his long-frizzled hair dry under cover to protect himself and to prevent the disaster of an electric shock. Others, captivated by the projects of Franklin, were indeed electrocuted in performing lighting experiments during the months immediately following, which highlighted the danger and the importance of the possibility of this discovery. Not one to be disengaged from his passions, Franklin invented the ‘lightning rod’, the first real step in surge protection.

Enlightenment

Finder’s 7P Series surge protection devices

1775 marked the year that Alessandro Volta, a professor of physics at the Royal School in Como, developed an improved version of the ‘Electrophorus’; a device that produced controlled, high voltage, static electricity. Volta continued his investigations and in 1776 ignited methane with an electrical spark, 80 years before the invention of the spark plug. One of the first to develop a real understanding of electricity, Volta went on to create the ‘Voltaic Pile’, a precursor to the modern battery, and now all those volts in a surge are named after him as a mark of his discoveries.

“Changes in the 18th Edition of the Wiring Regulations mean that surge protection devices (SPDs) have increased importance in installations.”

The world surges ahead Franklin’s invention of the ‘lightning rod’ provided the world with what was thought to be almost all of the protection it needed, stopping tall buildings from catching fire during the vicious thunderstorms that arose, until the invention of the ‘electric telegraph’. However, the development of electrical distribution systems in the late 19th Century brought the unfortunate consequences of electrical disturbances to everyone. And as those systems and the attached installations manifested in size, complexity, and value, so did the need for a more sophisticated approach to protection. That leads us to what we have today and the topic of this article – a new change in the wiring regulations.

Changes to the 18th Edition of the Wiring Regulations January 2019 represented an important milestone in the industry. Changes to the 18th Edition of the Wiring Regulations went live, and some of these changes mean that surge protection devices (SPDs) have increased importance in installations. Now, a risk assessment is required to be carried out by an electrician to determine whether

an SPD should be installed. If a risk assessment is not carried out, then an SPD must be automatically installed. The risk assessment should consider criteria such as: •T  he probability of lightning strikes •T  he exposure of the building to transients •T  he sensitivity and value of the electrical equipment that requires protection •E  arthing systems •L  evel of protection required Over-voltage protection is now required in certain circumstances, such as: where there is a risk of serious injury or loss of life; where many co-located people are affected; and where there is an interruption to public services or commercial/industrial activity. Finder supplies a complete range of surge protection to help protect expensive control panels. Included in its range is a surge arrester, suitable for 230/400 V system applications to prevent over-voltage effects caused by lightning strikes. The company also offers SPD Type 1+2, replacement spark gap and varistor modules (for single phase systems), and visual and remote signalling of varistor status. Finder, findernet.com

PROJECT FOCUS

LIGHTING UP THE RAILS Tridonic is helping Future Designs to meet Crossrail’s exacting specification requirements for an LED future. The company explains how the project unfolded.

I

f an entire infrastructure project is to be buried underground, then lighting is of paramount importance. This is certainly the case with London’s Crossrail line (also known as the Elizabeth Line), which will significantly reduce journey times across London for millions when it opens in 2019. “The decision to go LED on Crossrail was based on industry evidence that the benefits of reduced energy consumption and maintenance requirements would deliver a reduction in whole-life costs for the project,” said Paul Kerrigan, Crossrail MEP Engineer (lead electrical). The brief was for the lighting to emphasise the spatial envelope, rather than draw attention to the luminaires themselves.

All in the design

Plinth luminaires are located within the deck area between individual escalators, and are designed to reduce visual glare

The company tasked with meeting the design and performance requirements was Future Designs, and it called upon Tridonic’s technical expertise to help create a suitable bespoke lighting solution. The decision to use LEDs exclusively will significantly reduce energy consumption and maintenance costs, which will ultimately lead to a reduction in the wholelife cost of the project. Future Design’s concept uses the light grey, matt-textured, glass-reinforced concrete lining of the station and escalator tunnels to reflect light onto the passenger areas, to create a sense of spaciousness within the underground environment. The company created the following luminaires specifically for the Crossrail project:

By reflecting light onto the passenger areas, Crossrail stations will offer a sense of spaciousness

“The decision to use LEDs exclusively will significantly reduce energy consumption and maintenance costs, which will ultimately lead to a reduction in the wholelife cost of the project.”

An uplighter for indirect illumination

Emergency luminaires and anti-glare uplighters

The Ikon uplighter luminaire has been created to sit on top of wayfinding totems. This powerful luminaire is designed to illuminate the area via the ceiling, which then reflects the light back down to the floor. To provide this level of light, Future Designs utilised Tridonic’s proven driver, LCAI 150W 350mA-1050mA Eco Industry drivers, along with the LLE 24 x 280mm 2000lm 830 EXC modules, operating at a current of 950mA. The space between each of the totems bearing the uplighters is between seven to 11 metres, and therefore, these luminaires needed to produce 58,000 lumens / 850 watts (as a comparison, typical office lights are 5,000 lumens / 32 watts). Weighing in at 80kg per unit, and measuring just 685mm x 185mm across the lit face, the high wattage of Ikon generates an enormous amount of heat from such a small area which needs to be dissipated, and the most critical area of the design was calculating the precise dimensions and area of the bespoke heatsink to ensure that heat was drawn away from the LED system, regulating the device’s temperature. Critically, as heat rises, the heat sink design had to draw the heat down, away from the LEDs of the unit, which sits on top of the totem. Testing and prototyping for this specific section of the design took more than 350 hours, and a series of original prototypes were built so that thermal tests could be carried out to establish that the heatsink would control the LED temperature correctly and safely.

Ikon Emergency luminaires are designed to automatically illuminate in the event of a power failure, helping to guide Crossrail passengers to safety. The design features high and low-level lights mounted on the sides of wayfinding totems and horizontal luminaires mounted on the front faces of the totems to spread light in all directions and throw the light across a large distance on the floors. Each emergency system is 35,000 lumens / 230 watts, and the lights are operated from a 230-volt generator. Ikon Emergency and the Ikon totems will be installed in Crossrail stations at Tottenham Court Road, Farringdon, Liverpool Street, Bond Street and Whitechapel. Plinth luminaires are located within the deck area between individual escalators. The uplighters are specially designed to diminish visual glare to passengers travelling on the escalators, preventing a direct view of the LED source and providing well balanced lighting. The positioning of the LED at a low level in the fixture and a black louvre at high level ensures dark light anti-glare illumination. The luminaire is sealed to IP68 with a high level clear glass panel. Due to the proximity of passengers using the escalators, safety elements required that the glass panel had to withstand a 1,000N load applied over a 50mm x 50mm area. Plinth will also be installed in all five of the Crossrail stations. One of the challenges with this fitting was ensuring that faces would be illuminated when viewed on CCTV, but at the same time, ensuring that passengers were not dazzled as they travelled on the escalators.

COMPETITION

EXPLORE UNITRUNK’S BIG IDEAS AND WIN AN APPLE IPAD MINI 4

A

Our RIS UniKlip cable tray, EasyConnect cable basket and Speedway cable ladder systems have been expertly designed to offer faster, easier toolfree installation for installations up to three times faster than conventional alternatives. Not only does that help installers to get the job done on time, but it can also deliver significant savings in labour costs too, helping to reduce the overall cost of the installation by as much as 50%.

t Unitrunk, we’ve always admired Apple’s extraordinary ability to innovate and lead the market in its sector. With our RIS (Rapid Installation Systems) cable management systems, we believe we’re doing the same in our sector, with innovation that brings fresh thinking to traditional products and makes them easier to use.

The UniKlip cable basket system requires no nuts or bolts and simply clips together with our unique ‘klips’. This not only makes it faster to install, but also much easier – particularly in tight voids – while ensuring a robust and hard-wearing installation, because the klips cannot loosen over time like nuts and bolts can. The EasyConnect cable basket system is just as easy to use, with integral couplers that simply push together to form a secure joint. The Speedway cable ladder system has been designed to reduce the number of couplers and fixings required, thanks to an integral coupler with a formed shape that increases strength and rigidity and reduces joint hinging. To celebrate all this design innovation, Unitrunk is offering one lucky winner an Apple iPad Mini 4, worth £400. For company or product information, contact Martin Gregg, Commercial Manager of Unitrunk, by calling 02892 625 883 or emailing martin.gregg@unitrunk.co.uk.

OPINION

WASTE ELECTRONICS IN THE SPOTLIGHT Paul Reeve, FIEMA CEnv and Director of Business at ECA, discusses the latest updates to the UK’s WEEE regulations, and assesses the impact they will have on producers and distributors of electrical and electronic equipment.

T

he EU Waste Electrical and Electronic Equipment (WEEE) Directive was introduced over 10 years ago to boost the amount of WEEE that can be recovered, rather than landfilled. The UK’s WEEE regulations, which implement the directive, had their latest update on January 1, 2019, and they greatly increase the scope of electrical and electronic equipment (EEE) covered by the regulations.

SOME KEY TERMS

Removing WEEE…

Expanded scope... Many readers will already be aware of the application of the WEEE regulations to the recovery of fluorescent tubes, but the latest update means the regulations now apply to almost all EEE, unless it is specifically excluded. This wider scope even takes in everyday accessories such as plugs, sockets and switches.

Who does WEEE 2019 apply to? The WEEE regulations are based on the principle of ‘producer responsibility’, which means that the main legal duties fall on ‘producers’ and ‘distributors’*. However, this does not just mean manufacturers or wholesalers, and it’s possible to pick up the duties of a ‘producer’ by directly importing EEE from abroad (e.g. via the internet) or by adding ‘own brand’ labelling to EEE products. Among a range of duties, producers, importers and distributors must finance their share of the cost of recycling WEEE that will be collected via UK WEEE compliance schemes and take-back facilities (see the ‘producer responsibility’ section in the key terms section).

* Under WEEE 2019, EEE producers, importers and distributors have legal duties that include providing or paying towards the free take-back of WEEE. Larger UK producers or importers of in-scope EEE must pay to join a Producer Compliance Scheme and report the weight of the EEE they sell (minus any batteries). Producers supplying less than five tonnes a year in the UK may register with the Environment Agency (this also involves a registration cost).

“Significantly, anyone who stores or transports WEEE (e.g. as part of a replacement or maintenance contract) must still comply with applicable waste law.”

Significantly, anyone who stores or transports WEEE (e.g. as part of a replacement or maintenance contract) must still comply with applicable waste law (and some WEEE may be more costly hazardous waste). This means that clients must show diligence when choosing a waste service provider. However, the updated regulations do not put specific WEEE recovery duties on clients or their service providers. For these organisations, the commercial situation may even improve if they can take advantage of free WEEE recovery, brought about by the duties on producers and distributors.

Conclusion Readers in doubt about their businesses’ status as an EEE producer/importer may wish to visit the government’s website or contact their trade association or a leading WEEE compliance scheme, such as Recolight. The broader scope of the regulations should increase supply chain and customer awareness of WEEE recovery, which will in turn require better management of EEE waste streams, as a contribution to a more ‘circular economy’. In addition to the legal duties on producers and distributors, others – such as clients and contractors – may find that the new, broader scope presents practical challenges, but also some commercial opportunities. The ECA wishes to acknowledge the contribution of Recolight to this article, which outlines the updated scope but does not seek to provide definitive guidance. The lead Government Department is DEFRA, and further information is available at gov.uk/electricalwasteproducer-supplier-responsibilities

•C  ircular economy – Decoupling economic activity from a linear ‘make, use and dispose’ business/consumer model by extending the whole-life value of products and materials through product design, service-based business/consumer models, and increased reuse and recovery. • Producer responsibility – Ensuring businesses that manufacture, import and sell products are responsible for ‘end of life’ impacts, often through regulatory duties to: •D  esign products by reducing key material usage, and enhancing reusability and recyclability •M  inimise waste and promote product re-use (where possible) and recovery (which includes recycling) •E  nsure waste products are properly treated, and; •M  eet UK recovery targets for waste materials. • EEE – Electrical and electronic products that “depend on electric currents or electromagnetic fields for their basic function” – whether connected to the electrical supply, or battery or solar-powered. EEE applies to products, rather than spare parts or components. When EEE becomes waste, it is WEEE.

COMPANY PROFILE

The new showroom at Lewden’s offices enables visitors to see an array of Lewden’s most innovative products

LEWDEN

“THE BEST KEPT SECRET IN BRAINTREE” Simon Rowley, Editor of ECN, recently had the opportunity to visit electrical equipment supplier, Lewden, at its warehouse and offices in Braintree, Essex. This article sheds light on the company’s recent developments, and explains why Giovanni Baccini, its Managing Director, considers Lewden to be the best kept secret in Braintree.

F

Lighting designers and installers can find smart solutions within the LUX range, engineered to give long life and durability even in the most demanding areas

ully owned by Italian company, Palazzoli Group, Lewden has been supplying electrical equipment to industry for over 60 years. Opening its doors in the UK back in 1946, the company has become renowned for its product range and custom solutions, and it recently relocated its UK headquarters to a new, larger site in Braintree. Walking around the modern facility, you really get a sense of the company’s heritage and values, and a designated product education centre and showroom inside the head offices enables visitors to interact with many of Lewden’s most popular products right away. Lewden can use these areas to show visitors its latest products and explain how they conform with the latest standards, and the site is also used to hold sessions with wholesalers.

A constant evolution Starting life as a supplier of industrial connections, Lewden has significantly expanded its offering and, since 2012, has also offered domestic circuit protection products. These two elements are now both fundamentals of the business. The company has grown year-on-year for the last five years, and – courtesy of a new range of products – it now proudly services everything to help the electrotechnical market here in the UK. It has also relocated. Giovanni Baccini, Managing Director of Lewden, explained, “Lewden’s HQ was previously based in East London, but we decided to move further afield to a more spacious site. Part of the move to Braintree was also to provide us with space for future development in the coming years, and we’re now looking forward to expanding even further.” Lewden has fully embedded itself within the local community, and has also found many subsuppliers in the local area that it has worked with too. With both its brand awareness and its physical presence

continuing to expand, Baccini declared that Lewden could rightly be considered, “The best kept secret in Braintree.” In addition to the offices and education centre, the Braintree site also contains Lewden’s factory and warehouse, which house its extensive range of products for the industrial, commercial and domestic sectors. While the warehouse is primarily used as a custom build facility for providing bespoke solutions, it was interesting to learn that, since January, the team in the technical office have been busy on the phones, fielding questions about the 18th Edition of the Wiring Regulations. It’s not only the 18th Edition that’s prompting changes though, with Brexit uncertainty also leading to concern and confusion across the board. “To deal with Brexit, the company is taking proactive measures to minimise disruption for our customers”, continued Baccini. “We have increased our stock holding in Braintree, for instance, with three months’ worth of sales stocks here now; and we will replenish this stock depending on the Brexit latest and how it progresses.”

Complying with the 18th Edition

Lewden has introduced a new range of Surge Protection Devices in Type 2 and Combined Type 1,2 & 3 for both single and three phase applications

With the 18th Edition of the Wiring Regulations comes a requirement for new products, and Lewden has responded by launching a range of compliant solutions. Significant changes in the new regulations include guidelines on protection of electrical installations by using surge protection devices. The new regulations also lay emphasis on the correct selection and overload protection of the RCCBs and RCBOs for specific application needs. An exclusive section related to electrical installations in caravan or camping parks highlights the need of every socket outlet or connector to comply with BS EN60309-1-2 and be interlocked to prevent the socket contacts being live when accessible. In addition to a new and improved range of consumer units and circuit protection devices, Lewden is also committed to the safety of electrical installers and end users by being at the forefront of ensuring compliance with the requirements of the new regulation changes. Lewden’s range of Metal Consumer Units has been designed to be easily installed, aesthetically pleasing and unobtrusive, making them ideal for both domestic and commercial installations. The range consists of six enclosure modular sizes 4, 8, 10, 12, 16, and 21, with earth and neutral terminal bars clearly labelled and positioned at the top of the base. The unit has ample wiring space with a selection of knockouts, mini trunking and conduits to ensure quick and neat installation. The range has a maximum of 19 usable ways, in a variety of layouts. Lewden has also introduced a new range of Surge Protection Devices (SPDs) in Type 2 and Combined Type 1, 2 and 3 for both single and three phase applications. To allow for the installation of an SPD, one extra module of space has been provided within the new consumer units, without increasing the overall dimensions of the enclosure. A new range of Caravan Hook Up Units with RCBO - protected switched interlocked sockets has also been launched, allowing the possibility to incorporate up to four 16A or 32A switched interlocked sockets within a single unit. The range also features an overall 100A 2P main switch and 2P 30mA Type B 6kA RCBOs compliant to EN 61009. X-CEE, a new series of high performance IEC60309 industrial connections, has been designed to offer safety, performance, simplicity, versatility, and suitability against all environmental risks, for all applications and configurations. The result of a design phase that lasted about three years, Lewden describes it as a unique, complete and versatile product that adds value to the Palazzoli range. X-CEE introduces a unique feature, the rotoswitch, which is an industrial mobile socket to IEC60309-1 standard. The rotoswitch incorporates a switch disconnector (AC-23A) with mechanical interlock for safety purposes. The rotoswitch is a normal industrial socket with a switch disconnector with independent tripping and mechanical interlock integrated in a compact solution. It is described as a ‘small technical jewel’ with which you can bring safety throughout the plant, and not only in cases where

extensions are used, but also in confined places such as niches, manholes and work benches, thanks to panel and wall solutions.

A travelling education centre

Commercial and industrial lighting Introduced in 2018, lighting is one of the most recent additions to Lewden’s business. Its new LUX lighting division offers a family of premium industrial and commercial LED lighting manufactured in Italy by Palazzoli, along with other selected manufacturers. The range of high-performance LED lighting includes low bay and high bay, retrofit high bay, floodlight, amenity bulkheads, linear AISI 304 stainless steel and marine grade AISI 316L stainless steel lighting fixtures. Lighting designers and installers can find smart solutions within the LUX range, incorporating the latest technology, engineered to give long life and durability even in the most demanding areas. LED lighting fixtures for potentially explosive atmospheres (ATEX) and multi-chip LED lighting fixtures for tunnels are clear examples of these features. All Lewden LUX products have been developed with a ‘future-proof’ chassis. As the technology within the products changes, the aesthetics of the product remain the same, ensuring that replacement fixtures will retain an identical appearance when installed alongside existing fixtures. With a high level of corrosion resistance up to C5, and high impact ratings up to IK10, the LUX range is also totally protected against ingress of dust and the effects of being subjected to powerful jets of and immersion in water. The products within the LUX range seek to offer great versatility with multiple lumens outputs, mounting options and a wide choice of lenses, ensuring the best photometric solutions for any lighting project.

Lewden’s display van – which it calls the ‘travelling education centre’ – enables customers to step inside and view the company’s entire product range

Last year, an awareness program was launched to wholesalers in the form of a Lewden display van, which travels the country and allows customers to see, first-hand, the bulk of the company’s product range. I had the chance to step inside the van during my visit, and with such an array of products on-board, it’s easy to see why visitors have reported such positive experiences with the van. Each wholesaler branch works with Lewden to promote these events to all of the electrical installers who visit their branches. Meanwhile, the launch of Lewden’s product education centre at its head office in Braintree provides a further opportunity to engage with the key decision makers of electrical wholesaler groups and present to them its extensive range of industrial, commercial and domestic products, its in-house custom build expertise, as well as showcase its modern offices and extensive 4000m2 warehouse and dispatch operation. Starting this year, Lewden will also be attending the series of NICEIC Tech Talks dedicated for the electrical contractors and installers. There is also a new customer loyalty programme, named ‘Lewden Platinum’, which launched at the start of 2019. Lewden, lewden.com

SMART SENSORS – A SUPER ENERGY SAVER Energy and financial savings are high on the agenda when it comes to lighting both in homes and businesses. With new additions to the AOne range, Jeff Richardson, Aurora Group’s Trade Director, reveals how sensors can assist in reduced energy wastage.

W

hen customers seek to reduce energy costs, the first consideration is the lighting itself, but beyond energy efficient LED luminaires, how can home or business owners save more money? Sensing has become increasingly advanced in recent years and incorporated into affordable smart lighting systems to enable further energy savings, instant smart illumination and peace of mind in terms of safety.

Sensing with the AOne Aurora has recently introduced new products to its AOne smart lighting range. An affordable solution, this new range features two wireless sensors, both controllable by the AOne app. The PIR and Door/Window Sensor are wireless so can be easily installed. The PIR sensor (3M tape and bracket, 2 x AA batteries supplied) is paired to the AOne app following installation, which can then be configured and connected to the

What are PIR sensors? A Passive Infrared Sensor (PIR sensor) is an electronic sensor. It measures infrared (IR) light radiating from objects in its field of view. A PIR sensor reacts to detected movement, and not just to detected temperatures, so they are extremely effective when placed in areas where people frequent.

relevant lighting across a building, enabling automatic, instant illumination, at a pre-set level and time, where required, eliminating the risk of lights being left on when the room isn’t occupied, saving energy costs. Hallways and bathrooms are where PIR sensors can make a difference. Immediate occupancy detection allows lights to switch on only when space is occupied. At night, they assist in lighting the way to bathrooms without fumbling around for light switches and disturbing other family members. The AOne door/window sensor can be easily installed on a door or window frame, and help deter potential intruders by illuminating a room upon a break in the connection. They can also connect to outdoor lights, enabling instant illumination. The new AOne sensors, combined with Aurora’s high performing energy saving lighting, bring undeniable value to an already cost-effective smart home solution, giving enhanced energy savings and control.

OPINION

TAKE CHARGE OF YOUR PAYMENT POLICIES Lee Murphy, Founder of Pandle, offers advice on how electrical contractors can get their business growing and boost their income now that the 2018/19 tax year has come to an end.

I

f you’re a contractor who trades as a limited company, this 2018/19 year end has been particularly challenging. As well as filing company accounts, the majority have had to incorporate new software to meet obligations set by the Making Tax Digital initiative. Now is a good time to start making plans for the next year and make some changes that will really help grow your business and boost your income. After all, having filed company accounts, you’ll have all the paperwork you need to make the right decisions about your business. Here are some important points to consider for the coming year to reduce the admin and hassle that comes from bookkeeping problems.

Late payments Despite the collapse of Carillion shining a light on the issue of late payments last year, it continues to be an issue for many contractors. The Federation of Small Businesses is demanding that the government introduces measures to end a culture of late payment and “supply chain bullying”. It is not wrong, as late payments are a danger to many small contractors. Remember, being organised can help get many customers to pay on time. Always be clear about your payments policy and get it agreed up front; issue your invoice promptly with correct details, PO numbers and to the right person; and start chasing for payment before it is due – not once it is already late. It’s also worth considering how much time you allow customers to pay you. It may be worth reducing this to get payments sooner. It may come as no surprise that the longer a customer waits to pay, the less likely it is that they will. Not all late payments will be cynical, as sometimes customers simply forget. It’s down to you to make sure they are reminded, and that can be tough after a long day. The good news is that there are plenty of online tools available to support you in your efforts, many of which come free of charge. Pandle, for instance, automates the process of chasing and reminding customers for you, which is something that will have an immediate impact on reducing the number of debtors you have.

Online tools, such as the software offered by Pandle, can simplify paperwork and automate the payment chasing process

“The Federation of Small Businesses is demanding that the government introduces measures to end a culture of late payment and supply chain bullying.”

Payment retention Payment retention is another hot topic that could directly affect your business. Payment retention of between 5-10% is not unusual for most electrical contractors, and the money is held on account and meant to be returned within 12 months of completion. What happens when the main contractor has spent the money or simply forgets to pay? Delays are common, with some subcontractors waiting up to three years for payment, something that hits cashflow hard. This situation is untenable for many contractors. Hopefully, the government will legislate to put in safeguards for contractors, so they always get their money. In the meantime, there are at least some steps you can take to make sure you receive that final payment. Importantly, be organised about chasing down debtors ahead of any retention coming due – don’t wait for them to come to you.

Cashflow forecast Having completed your accounts for the year-end, you should have a clear snapshot of your financial health. But for managing your business, the key document is your cashflow forecast, done on a monthly basis or even weekly in tough times, so that you know how much money the business is paying out and how much money it has coming in each month. Many businesses that go under are not loss making. They simply run out of cash because there is not enough coming in and

too much going out, so they can’t pay for vital costs such as salaries, tax demands and equipment. The forecast should include your material costs, rent and any employee salaries, as well as big lumpy payments like your annual corporation tax, quarterly VAT and large ad-hoc payments. These are particularly important because, if you have not set aside money, you may well not be able to pay them.

Beware your customers Now is the time to audit your client list and ensure you avoid those who are not paying enough for your time, and also be wary of becoming over-reliant on one or two customers for work. It is a lesson to all contractors that while a large customer might seem a good idea when business is quiet, it could have disastrous consequences if the contract terms are too onerous or if big commercial customers start taking advantage of the relationship. Taking the time and care to put your finances in order will make life easier for the next year, showing you how much money you have to invest and grow your business. Now is the time to get started.

ASK THE EXPERT

Q&A: HAGER ADDRESSES SURGE PROTECTION Following the introduction of the 18th Edition of the Wiring Regulations, Paul Collins, Technical and Training Manager at Hager, answers some of the most frequently asked questions in relation to surge protection. What does the new regulation cover? The regulations state that protection against short, disruptive transient excessive voltage levels shall be provided where the consequence of an overvoltage could be damaging to human life, interrupt public services, adversely affect commercial or industrial activities, or affect a large number of individuals occupying the same building. How do I know if I need to install a device? Should your installation not form one of the above, then a risk assessment method can be used to determine if surge protection devices should be installed. For a single dwelling, the owner needs to make an informed decision whether or not to have the installation of surge protection devices in their property. In order to correctly come to the decision, however, they will need to understand what these devices are and what the consequences could be of not having them. All of their electronic

equipment could be damaged, and even the installation – and potentially, the building itself could be damaged should the voltage surge be severe. Does it matter where in the board I fit the surge protection device? Yes. It should be as close as possible to the origin of the electrical installation, with the shortest, straightest cable links between the connection points and the surge protection device. The recommended length of cable is less than 0.5m, but in no case should it exceed 1m. What does a consumer unit surge protection kit consist of? A Hager surge protection kit for a consumer unit consists of a surge protection device and the required cable links.

A severe voltage surge can potentially damage an entire building, so it’s vital that surge protection devices are installed correctly

3-7 pole ceiling rose THE WORLD’S F IRST 7-POLE ‘ D E C O R AT I V E ’ C E I L I N G R O S E

Do I need a protective device to supply the SPD? The new Hager domestic SPD is a ‘fail safe’ device that cannot fail to short circuit. Therefore, it does not require the additional protection and space requirement of a circuit protective device, when installed within the consumer unit. For commercial applications, it may be that an additional circuit protection device is required to connect the device to the distribution board where required. However, Hager’s commercial board SPDs will typically employ integrated fuse protection, so an additional circuit breaker isn’t required. Hager is happy to assist with this required information to make selection easier for the designer/installer. Hager, hager.co.uk/18thEdition

COMPANY PROFILE

DETA

Q&A – DETA WIRED FOR SUCCESS ECN recently had the chance to speak with Andrew Pegrum, Technical Manager of Deta, who provided insight into the 18th Edition, smart homes, the company’s latest products, and even Brexit. ECN: With the cable and cable management industry evolving in 2019, how sophisticated are today’s cabling products compared with what was available a decade ago? Pegrum: Cable management systems are principally the same as a decade ago, with the use of conduit, trunking, tray and basket systems still as much use as they ever have been. However, the method of installation of each of these systems, or the way cables are attached to trays and basket systems, is more important than it ever has been, particularly with the publication of the latest edition of the IET Wiring Regulations.

Cable management systems, such as Deta TTE steel conduit tube fixed in place with steel saddles, will meet the requirement of the new wiring regulations

ECN: What does Deta recognise as some of the most important trends, and how are you responding to them? Did the changes outlined in the 18th Edition of the Wiring Regulations have a big impact? Pegrum: Changes in the 18th Edition of the Wiring Regulations require that wiring systems that pass over access and egress routes are supported by metallic fixings to prevent them from drooping under fire conditions, and making access for fire fighters dangerous. Metallic cable management systems, such as Deta TTE steel conduit tube fixed in place with steel saddles, will meet the requirement of the new wiring regulations. Whilst plastic cable management systems can be used, they will need supporting by metallic fixings, which can be painted to colour match to white and black conduit.

ECN: What are some of the main challenges electrical installers are facing in today’s era, as it relates to cable management? Pegrum: Specifiers and installers must ensure wiring systems are designed and installed so that they take into account how the building may be used – not just at the original installation, but should, say, a partition office change layout. Where this happens, the access and egress routes can change and as this happens, wiring system supports will need changing to ensure compliance with the regulations. ECN: Now that the 18th Edition of the Wiring Regulations changes have been implemented, how do you see the cable and cable management landscape evolving? Pegrum: The use of plastic trunking systems to route cables, say, over doorways is likely to reduce. Whilst the regulations require that cables are supported with metal fixings in access and egress routes, the fire and rescue services advise that they can use any route to gain access (through windows, for example). In view of this, it is not just wiring systems in access and egress routes that should be supported with metallic fixings, but all wiring systems.

“Deta is working with its manufacturing plants to manage the uncertainty that Brexit brings, and to increase its stockholding to ensure continuity of supply to meet the needs of our partners and ensure supplies are not disrupted.”

ECN: From your standpoint, what makes Deta’s products so unique? Pegrum: The steel conduit tube and malleable conduit boxes, along with the accessories that Deta offers under its Deta TTE brand, automatically meet the requirements of the 18th Edition of the Wiring Regulations and have been supplied into the market for many years, both in the UK and the Middle East. They have been installed on many prestigious projects, including Wembley Stadium, Dubai International Airport and The Louvre Abu Dhabi. To ensure continuous supply, Deta has an extensive stock holding, enabling an unrivalled service and support for the range. ECN: How is the advent of smart homes affecting Deta’s business? Pegrum: The use of smart home technology is becoming more and more prevalent, and Deta’s Connect range can be retrofitted in existing installations or designed into new build properties. Smart home systems with in-house controls are ideal, as they provide standard recognisable switches and controls, and you don’t need to find your phone just to switch on a light. Where smart home controls really come into their own is where you can use virtual assistance devices, such as Alexa, to give you voice control. Even more so, where timers can be used to add control to devices, particularly when you’re away from home or on holiday, smart home technology has a real advantage. The prolific growth of smart devices needs multiple charging outlets. USB sockets with multiple high current outlet ports offer an easy and convenient way of charging these devices.

Deta’s range of Vimark IP65 LED integrated downlights replicate the effect of traditional incandescent and halogen lamps

COMPANY PROFILE

ECN: What does Deta have planned for the rest of the year and beyond? Pegrum: Deta has just launched its latest range of LED lighting, the Vimark IP65 LED integrated downlights, which includes AmbiDim technology that replicates the effect of traditional incandescent and halogen lamps. This fitting enables a relaxed and ambient lighting atmosphere to be created, and it provides a warmer lighting tone (3000K to 2200K) as light levels are reduced. In addition to this, Deta has a range of projects on the horizon, including a range of Vimark circuit protection boards as an ‘over the counter’ range.

Deta’s conduit fittings allow installations to be configured to meet all design requirements, without the need for bespoke solutions

ECN: Has the company set any other challenges or goals for the year ahead? Has Brexit had a big impact on your business yet? Pegrum: Deta continuously sets itself challenges to not only meet its ISO 14001 Environmental Management System targets, but to also keep the company moving forward.

INDUSTRY DEVELOPMENTS

Developed by Rexel Austria, the Rexel Power app enables users to analyse and optimise their energy consumption in order to realise cost savings

IT’S A SMALL WORLD Mark McCall, Product Manager at Rexel UK, discusses his thoughts on developments within the industrial electrical distribution market, and what he has learnt from a valuable European network of colleagues.

L

ike all sectors of the electrical distribution market, the industrial sector is facing a changing landscape as we head towards 2020 and beyond – but can we learn how to react to this changeable market in the UK by working closely with our peers on the continent?

A European network Being part of Rexel UK also means being part of a wider international group, and there is often a lot we can learn from our counterparts over in Europe and even further afield – collaborative working need not be impacted by borders. Often, we find ourselves at different stages of development to those overseas, and whilst we bear in mind variances in market place and customers – and whether we lead the way or follow an already trodden path – this insight can be invaluable. Recently, I met with many industrial colleagues from around the network, and we explored some of the key topics impacting our area of the industry.

IIoT and automation A recurring theme of the discussion was Industry 4.0 and IIoT (Industrial Internet of Things) – something that we all know remains a hot topic across the whole electrical distribution industry. The IIoT is a subcategory of the wider IoT (Internet of Things), which relates to the digitalisation of manufacturing and processing businesses, where a network of smart devices can connect and share huge amounts of data connecting people, data and analytics and machines. Simply put, the data is collected and stored in a cloud, and algorithms are used to display the data in a usable format. It is then used to make the decisions on how, and where, to improve the process, all for the benefit of the user. Ultimately, this connectivity – and the learnings available from such a vast amount of data – will lead to improved and much more efficient processes for our customers. There is such great potential for the Industrial Internet to change the way industry works, that GE Digital predicts the benefits to the global economy through IIoT will be:

•4  6% of the global economy can benefit from the Industrial Internet •1  00% Industrial Internet potential impact on energy production •4  4% Industrial Internet potential impact on global energy consumption For many of our European colleagues, working with a more developed and established industrial solution strategy, their focus is moving towards this development of automation thanks to the IIoT. And many of the distribution networks in other countries are having conversations with their customers about automated manufacturing and improving current production output, with a focus on using data to inform any developments. We are already seeing benefits on the continent. Specifically, as one example, our colleagues in Austria have developed a solution for energy management in partnership with Siemens, which can be managed through the Rexel Power app. The system is a combination of sensor hardware, the cloud and big data analytics tools, and it enables customers to analyse and optimise their energy consumption in order to realise cost savings.

INDUSTRY DEVELOPMENTS the perception here is that of concern around increased automation, with people feeling it can have quite a negative impact on jobs. However, the opinion abroad is that it actually can release skilled workers that may be performing tasks far beneath their skill level to undertake roles much more in line with their experience and expertise. In the UK, we may experience a lack of take up, but the opportunities are endless. For us, the need for sensitivity around automation, whilst realising the progression in this area and a need not to fall behind the continent, is something we must remain aware of.

Legislation Staff from Rexel’s European network recently met in Amberg, Germany for a best practice workshop

The design process for new machines can be made easier for engineers, with products such as a ‘digital twin’. This allows a machine or process to be designed and developed for a manufacturing process digitally, enabling the engineers to understand any issues with the design and function of the machine before the machine is put into production. These new solutions will enable better efficiencies for our customers. Currently, the UK approach differs from the approach adopted on the continent, with automation having had less impact here. In Germany, for example, the amount of automation versus the amount of industry dwarfs that of the UK. So far,

When it comes to working across borders, it is also worth considering legislation – both in terms of understanding and learning from possible progressive international legislation, and remembering that some countries may face restrictions not presented to others. For example, wiring and lighting legislation and trends differ across Europe, whilst within the industrial sector, we all adhere to European IEC Standards, with some British Standards still referred to in the UK as well. This conformity across the continent with the control and automation market has enabled the manufacture of machinery that can be used in multiple territories. And with the development

FEATURE

of more open networks, manufacturers and customers from across Europe can work together on the same systems and standards – something that will only continue to bring us all even closer together in the future.

“The system is a combination of sensor hardware, the cloud and big data analytics tools, and it enables customers to analyse and optimise their energy consumption in order to realise cost savings.”

Differing strategies A key part of the recent meeting however, was to take part in a best practice workshop in Amberg, Germany, hosted by Siemens, focusing on the launch of Rexel Industrial Solutions. Within this sphere, it was great to understand the differing strategies and focuses of the various countries. Of course, we know that all countries have different types of consumers and purchasing patterns. For example, in other countries, consumers tend to follow trends and regulations more stoically; whilst in the UK, we see customers creating their own solutions to answer their own need. In the UK, Rexel is developing specialist teams in place to best serve customers with industrial solutions, some of which are already championing our industrial offer. We know going forward that having a technical, specialist team with a great knowledge base is absolutely essential, and where our UK knowledge and wider international experience will really go on to benefit our customers.

WIRING ACCESSORIES

SKY’S THE LIMIT FOR SMART CEILING ROSE Exclusive details of the world’s first BS67 Smart Ceiling Rose, including information on how you can help the start-up of its manufacture.

A

start-up has made an improvement to the BS67: 1987 ceiling rose. Sometimes called a ‘loop-in ceiling rose’ or ‘three plate ceiling rose’, this is effectively a junction box for the power feed, switch wire and pendent flex of a ceiling light. The ceiling rose is part of the most common lighting circuit currently used in millions of homes as a ‘loop-in’ terminal box. Typically, a traditional ceiling rose requires the operation of a wall switch to switch lights on or off. The smart ceiling rose invented by the start-up switches lights automatically by overriding the wall switch. If used as a replacement ceiling rose in a retrofit, there is no need for rewiring or builders work. Once installed, it requires no maintenance – it is fit and forget technology. The smart ceiling rose reduces utility bills and combats domestic carbon emissions, which are currently 26% in the UK. The idea for the smart ceiling roses came from Moni Razzaque, a Chartered Building Services Engineer (CIBSE) with a specialisation in electrical engineering, who became fed up with his children always leaving lights on in his house. Before Razzaque came up with his idea, he visited several hardware stores and searched for something that would switch lights off automatically, but couldn’t find anything that would avoid rewiring, builders’ work and maintenance. Instead, he found himself improvising by cannibalising a PIR sensor from an outdoor patio light and rewiring its control facility back into a standard ceiling rose. With no pun intended, that was when he had his light bulb moment. Smart ceiling rose (prototype) with pendant luminaire

An early protoype Despite the unsightly appearance of the crudely assembled device, he knew he had constructed an early prototype of the device he wanted. He tabled his device (complete with dangling wires) in front of Les Norman, Principal Lecturer at London South Bank University (LSBU) and asked him for his opinion. Norman’s first remarks were that the idea was so obvious that he should first check his invention with the patent office at the British Library IP office. He also suggested that, in the unlikely event it had not been patented, he could consider approaching the Carbon Trust for support to develop the idea further. It was determined that there was no UK patent for improving the BS67 ceiling rose. Razzaque approached LondonIP, a patent attorney firm that worked closely with the patent office at the British Library, to write the patent. It took LondonIP several months of preparation before it could file a UK patent application titled “Apparatus for improved ceiling roses”. Once the patent was filed, Razzaque approached the Carbon Trust and discovered they had an Entrepreneurs Fast Track (EFT) programme, which was designed to help entrepreneurs by incubating and investing in low carbon solutions. To be eligible for this programme, Razzaque had to demonstrate that his invention provides evidence of carbon reduction. He provided evidence by

Table 1.0: In Razzaque’s first ever field trial, he identified a saving of up to 173%

conducting a field trial in his own home, and then had the results independently validated by London South Bank University. For the field trial, Razzque used a section of corridor between his children’s bedrooms. By connecting a data logger to an existing ceiling rose, he gathered a months’ worth of data before replacing it with his device. The actual energy saving in this location was staggering. In his first ever field trial, he identified a saving of up to 173% (Table 1.0). In the following six months, the Carbon Trust commissioned various marketing studies, and there was now overwhelming mounting evidence that the low-cost solution with the smart ceiling rose could present a simple and practical opportunity for consumers to stop wasting energy and reduce utility bills. A national consumer survey with 6,000 respondents stated 83% of consumers would have a propensity to purchase the device. If sold at an RRP of £29.99, the device would sell like smoke detectors. The start-up now needs help to manufacture. Razzaque and his team are focused on bringing the smart ceiling rose to market through a Kickstarter crowdfunding campaign. For future projects, the UK patent will allow for future exciting developments, which will include a smart ceiling rose that is integrated with smoke detection, intruder alarm and Wi-Fi connectivity.

SAFETY & SECURITY

SECURITY WITH SUBTLETY When Pennington Street Warehouse required a new fire and security system, WLS designed an installation that answered both the unique challenges of the Grade II listed building and the aesthetic goals of the end-user.

Jeremy Ewen, Managing Director of WLS

The fire and security system was designed to be discreet and as unobtrusive as possible

F

or most new build office schemes, the fire and security installation is largely hidden within the service voids, along with the rest of the electrical and mechanical installation. However, the interior design and layout of the Pennington Street Warehouse in East London did not allow for ceiling voids and cabling hidden behind wall finishes. Constructed in 1804-1806, the brick warehouse has been tastefully restored to retain the original arches and vaulted ceilings at ground floor level, exploiting generous ceiling heights with a new mezzanine level. New glazed elevations and partitions, along with lightweight staircases, a neutral colour palette and extensive use of timber create a light, bright workspace that reflects the design credentials of the architectural practice. In line with that aesthetic, JTP was keen that the fire and security system should be as unobtrusive as possible, which involved a solutions-driven approach from WLS. “Not only did we lack voids for hiding the installation away, we also needed to make sure that any visible elements of the system were discreet,” explains Managing Director of WLS, Jeremy Ewen. “Fire alarm and security systems are designed for functionality rather than aesthetics, so this involved considerable planning and close co-operation with the end user, the M&E contractor and the main contractor.”

A wireless fire alarm One of the biggest challenges for WLS was that the cabling for the fire alarm and intruder alarm systems could not be routed through either the glazed elevations and partitions, or the heritage brick walls and ceilings. Surface-mounted cable management was equally out of the question. To overcome this, the company opted for wireless fire alarm and intruder alarm systems. The wireless fire alarm system is a BS5839 L2-compliant installation, which included automatic fire detection on all escape routes and rooms leading onto escape routes. The building is relatively narrow and 315 metres long, with six external doors, all of which are escape routes. The fully-addressable system incorporates wireless smoke detectors and sounder-bases throughout the three-storey building, programmed on a closed protocol. “The wireless system solved the problem of maintaining the aesthetics of the interior,” Ewen continues, “but it threw up another problem because the thick walls that had originally been constructed to create a controlled environment for storing rum and spices also controlled how far the signal could travel. Obviously, it’s vital for a fire alarm system to be completely effective throughout the building, so we installed radio boosters to ensure the wireless network is reliable.” While the fire alarm system installed at JTP’s studio has not been integrated with the security installation, the building is part of a wider complex, and WLS was asked to link the system to the fire alarms for the surrounding offices. Consequently, it was programmed to interface with the other system so that any fire in any part of the complex is indicated on the corresponding display panel.

Intruder alarm For the intruder alarm, WLS selected a Texecom wireless system, which is monitored off site to ensure that a key holder is alerted if the alarm is triggered while there is no-one in the building. This system operates on a different wireless protocol to the fire alarm to ensure that the two installations remain independent. Ewen continues, “Again, we incorporated signal boosters into the installation to overcome the challenges of enabling the wireless network to communicate through the heavy brick walls and ceilings. The reason we selected this particular system is that it has a clever ricochet capability. If any of the devices

we’ve installed are struggling to pick up a signal, it will automatically request to share the signal of the nearest device and piggyback it for as long as required. However, it can only piggyback a signal from its own protocol so the signal for the fire alarm is never affected.

Access control Alongside the alarm systems, WLS also designed security for each of the six entrance points into JTP’s studio, with a combination of access control and CCTV. There is a CCTV camera with HD image quality on each of the external doors, providing continuous recording that is hardwired back to a network data storage capability. For the access control system, each member of staff has been issued with a fob uniquely programmed with their profile, which they must use to enter or exit the building. JTP opened its doors to clients and associates in February to showcase its new offices and nobody commented on the security installation, because it’s largely invisible against the backdrop of the stylish accommodation.

LIGHTING

IMPERIAL LIGHTING FOR DESIGN SCHOOL The Dyson School of Design Engineering has increased its energy efficiency following the installation of a new, comprehensive BEG lighting controls system. The solution is also enabling the maintenance team to control the lighting via their smartphones.

T

he tenth and newest engineering department at the Imperial College in London (ICL) was established in 2015, thanks to a £12 million donation from the James Dyson Foundation. Opened by George Osborne, the Chancellor of the Exchequer, and Sir James Dyson in 2015, the school was launched to help the next generation of much-needed graduate engineers and technology leaders. BEG Lighting Controls was selected by ICL to provide a user-friendly system which could be maintained by their own maintenance department and meet the lighting control standards required by the research university. The lighting controls manufacturer worked with mechanical and electrical consultants, Buro Happold, which was tasked to oversee the project and ensure that the system achieved the best solution for ICL.

The design brief ICL’s main criteria was that the project had to result in energy cost savings for the university, for the various areas of the Dyson School department, and take advantage of any natural daylight. This included the teaching rooms, laboratories, offices, corridors, stairwells, toilets and store rooms. BEG Lighting Controls and Buro Happold worked on the layout of the lighting, as well as the level of light and type of control required for these areas.

Tom Greenrod, Specification Director at BEG Lighting Controls, said, “The design brief from the ICL meant we had to carefully specify lighting control products for each area, which differed greatly from room to room – so this was by no means a ‘one size fits all’ solution. It was imperative that the lighting was mostly switched on in the offices and teaching rooms during working hours, and that it could be controlled to reduce lighting levels when the natural daylight was brighter. For the laboratories, we used Dali photocells instead of occupancy sensors.” He continued, “Areas such as the corridors, stairwell, toilets and store rooms did not need to be fully lit, and lighting only needed to be switched on once our occupancy sensors sensed there were people in the room. It is in these areas, naturally, that the most energy consumption could be saved, so it was vitally important we selected the right products for these areas. Via our extensive range of BEG Dali Broadcast Occupancy Sensors, we were able to offer a suitable sensor for all sections of the building.”

In certain areas, lighting only needed to be switched on once occupancy sensors sensed there were people in the room

Designed to dim The luminaires selected on the project were Dali dimmable, and daylight harvesting was to be achieved mainly for the light fittings adjacent to the windows. For these areas, the BEG DAA4G Occupancy Sensor was chosen, as it could be programmed so that the window luminaires were dimmed by 25% to the main room. If the sensor’s photocell detected any change in the level of natural daylight, then all luminaires would adjust accordingly. This sensor was specifically used in the teaching rooms, where up to four lighting zones could be set; one being the whiteboard, and then up to three zones for the classroom. A two-gang retractive switch would control the whiteboard and the main classroom lights. Programming of the sensor was achieved using a smartphone with the BEG lighting controls app and infrared adaptor. This app also allows remote programming of all of the Dali sensors used on the project.

BEG’s lighting controls app allows remote programming of all of the Dali sensors used on the project

Occupancy control The only mains fitting on the project was a feature chandelier in the main stairwell. Greenrod explained, “This needed to be controlled by occupancy sensors, together with the Dali luminaires. We solved this by using their sensor with a Dali and switching output. This sensor was also used in the toilet areas, where the lighting and the extraction fans required occupancy control. The Dali would control the luminaires and monitor any natural daylight, whereas the fan was controlled independently and worked on occupancy detection only. He continued, “A feature of the Dali master detector is the orientation setting, where the lights can be set to 20% once an area is unoccupied. This function was used in the circulation areas so that some illumination was provided at all times, which was considered to be a useful comfort and safety feature.” In laboratories, occupancy sensors were not required, as ICL wanted to avoid the possibility of lights turning off which could be considered unsafe depending on the type of experimental work being carried out. In these rooms, the BEG Dali photocell was used to control the window row of luminaires, to provide some level of energy saving. Greenrod added, “Once ICL appointed the electrical sub-contractor, BEG Lighting Controls was happy to provide technical support by attending site meetings prior to first fixing to ensure that the wiring philosophy was understood for each type of Dali sensor to be used on the project. “The main considerations were whether the sensor needed to be in presence or absence mode, if manual switching was required and the wiring of master and slave sensors. These meetings ensured that a smooth trouble-free installation was achieved. Once all the sensors had been installed, BEG Lighting Controls was on site to provide a commissioning certificate. We also gave sensor programming training to the university’s maintenance team.” BEG, beg-luxomat.com/en

RAMPING UP THE HEAT A popular skate park in Cheshire is ramping up the heat thanks to Tansun’s Apollo heaters.

B

ased in Warrington, Cheshire, Ramp 1 is one of Europe’s largest indoor skateboard, BMX, scooter and inline sports facilities. Spanning 50,000 square feet, Ramp 1 hosts nine different areas for beginners, under 10s, BMX riders and features a huge 112ft long bowl, a 40ft skateable tunnel and a 165ft Las Vegas themed street plaza. Its premises have been carefully designed to incorporate a range of specialist equipment for all abilities to enjoy, and have been fitted with Tansun infrared heaters to keep its many visitors warm throughout the year. Following discussions and a site survey, Tansun’s Apollo infrared heaters were chosen as the most suitable solution for the skate park. Eight Apollo A1K infrared heaters were installed and are controlled via localised switches for individual zones, allowing visitors to control the heating in areas only when and where required, reducing unnecessary energy consumption. Neisha Smith, Manager at Ramp1, commented, “The heaters are cost-friendly and easy to use, and we simply switch them on when we need them. They benefit us as the café area can be very cold, so having the heaters there makes customers feel warm and welcome. The skate park is a very large open space, so we are finding that the heaters work well, and we are very happy with the results. We would recommend Tansun heaters to others looking to achieve a more direct acting and efficient heating solution.”

“The infrared heaters allow visitors to control the heating in areas only when and where required, reducing unnecessary energy consumption.”

30 years and 30 models

Following discussions and a site survey, eight Tansun Apollo A1K infrared heaters were installed and are controlled via localised switches for individual zones

The Apollo range was designed to solve heating issues in large and problem areas such as gymnasiums, warehouses, aircraft hangars and places of worship, and with more than 30 models to choose from, this established product has been proven by Tansun for 30 years or more. The heaters come with high power options, special long-lasting aluminium reflectors, a focused energy beam and a high intensity heat, which, due to the highly engineered construction and design, would be difficult to rival in such large open spaces. Apollo heaters are available in 1kW to 18kW versions to heat areas up to 79 square metres, and they can be wall

mounted or hung from the ceiling. Tansun infrared heaters also benefit from a twoyear warranty. Tansun’s infrared heaters offer maximum performance and very low running costs. They are designed with a ‘fit and forget’ reputation, are reliable, durable and virtually maintenance-free. Features include extruded aluminium heat sinks to keep heaters cool for better reliability. The shortwave technology is also noiseless, does not contribute to air pollution, and is compatible with energy saving controllers. All of Tansun’s products are made in the UK, and are designed using premium components. The company has been established for 35 years and pioneered the concept of infrared electric heaters alongside Philips technology. Tansun has the largest range of commercial, industrial and domestic infrared heaters in the world, providing maintenance-free, safe and healthy shortwave heaters for many different types of heating applications.

THE DEVICE THAT MAKES AC CONTROL A BREEZE The GESM-AC controller is a battery-powered PIR sensor that provides auto on/auto off switching of infrared controlled AC units

With its GESM-AC occupancy detector, CP Electronics has simplified the installation of effective AC control. Neil Baldwin, the company’s Area Sales Manager, explains how the clever controller can help contractors to win new business.

W

hile still very much a luxury, air conditioning is an increasingly common sight in large-scale commercial and public buildings, such as hospitals, schools, universities and offices. It’s obvious why, as people want to live and work in comfortable environments. However, with the rise of air conditioning, we’ve also seen energy use – and its associated costs – soar.

The Carbon Trust has estimated that air conditioning can increase a building’s energy consumption and associated carbon emissions by up to 100%. This has an obvious impact on the operational costs of a building. Despite these issues, organisations are increasingly seeing air conditioning as mandatory for people’s comfort as well as extending the lifespan of IT equipment, protecting it from the excess heat it generates. Frequently, this means that air conditioning is left running continually, 24/7, whether through necessity or absent-mindedness.

“Generally, occupiers aren’t the bill payers, so there is little incentive to be mindful about switching off the power when leaving a room.”

One major factor is the lack of ownership – both literally and figuratively – of the people using the AC system. Generally, occupiers aren’t the bill payers, so there is little incentive to be mindful about switching off the power when, for example, leaving a room. Or they’ll intentionally leave the AC on overnight in the office to ensure a nice temperature the next day. Given air conditioning’s contribution to energy spend, it’s clear that any innovation that can stem this rise, which can positively impact on energy efficiency, should be welcomed.

“The GESM-AC’s simplicity of installation will reduce time on site, meaning that a costed project can be completed more quickly to move on to the next.”

Wired for success Historically, the main method to achieve effective air-conditioning control was to install integrated control systems into units; but the downside is that these often come as optional extras, which can cost lots of money.

Reducing the energy costs As a lighting control specialist, CP Electronics is always conscious of the energy savings that can be achieved by automating the switching on and off of lighting within unoccupied buildings. Realising that the same expertise can be applied to air-conditioning, CP Electronics developed the GESM-AC controller. This is a battery-powered passive infrared (PIR) sensor that provides auto on/auto off switching of infrared controlled AC units. The result is a system that regulates usage based on room occupancy – ensuring that air conditioning is only powered when a room is occupied, rather than running continuously, to save energy costs. The detector must be positioned where it can ‘see the room’ and also the AC unit, so that the infrared can communicate and also detect movement. As long as this is done, the GESM-AC will limit air conditioning usage to times when it’s necessary – and switch it off when it’s not. That’s a real win, but the even bigger benefit is its versatility.

On the one hand, the GESM-AC can be hardwired via USB, which makes it ideal for new buildings and future projects, as developers can specify the unit to build energy efficiency into the framework and infrastructure of their buildings. On the other hand, the unit can be surface mounted and battery-powered, with no wiring needed, and is also suitable for handheld operation. This makes it ideal for retrofit and refurb projects, as well as for small fit-out operations. Crucially, each GESM-AC can be programmed with a time delay. Five different time settings are available, with a time delay from as short as 10 seconds to as long as 30 minutes. This is so that the AC unit doesn’t switch off straight away as soon as you leave the room – which could be annoying if it keeps starting up and switching off – but still delivers a dramatic reduction in energy usage. Another option is to set the controller to ‘absence detection’ mode. This means the controller is only taught the ‘off’ signal, and it won’t turn the AC back on automatically. In other words, the onus is on the occupier to manually switch on the AC, further minimising usage. For installers and contractors, GESMAC does the same thing as the integrated controls, but there are no additional installation costs. The lightweight controller can be fitted, either by screwing or gluing to the tile, and programmed in less than two minutes – with no need to connect to mains power, no wiring or

electrical engineering expertise, and no need for specialist tools or equipment to get it up and running.

Reaping the rewards As a result, the GESM-AC’s simplicity of installation will reduce time on site, meaning that a costed project can be completed more quickly to move on to the next. Consider the disruption and downtime that wiring and installation of traditional units could cause in an environment as critical as a hospital. GESM-AC eliminates this, giving installers and contractors a stress-free installation, while keeping public disruption to a minimum. Add this to the benefits that the GESM-AC brings to customers in terms of energy savings, and it’s clear this handy device can be a real reputation boost to installers, especially when tendering for work with estates managers and facilities managers. Ultimately, all of this combines to make the GESM-AC the perfect entry-level route to a more cost-effective, energyefficient building. A smart, yet simple solution to energy saving, it won the 2018 RAC Cooling Award for air conditioning product of the year – accessories and peripherals. Given the importance of energy efficiency, not just to saving money but minimising environmental impact, the way that the GESM-AC opens up smarter air conditioning control to everyone is justifiably a cause for celebration.

BOILER INSTALLATIONS WITH ADDED VALUE Alan Clarke, Technical Support Manager at Heatrae Sadia, provides his top tips for making a success of every electrical boiler installation.

I

n the UK, it is estimated that around 15% of homes are not connected to the mains gas network. With the increasing number of high-rise and rural developments, this percentage is likely to increase, leading to an increase in demand for electric boilers. Here are seven important tips to consider when installing electrical boilers:

Understand the homeowner’s needs The installation of any heating system requires an understanding of the heating and water requirements of the homeowner. Generally, electric boilers are heat-only and so the property will require a hot water storage tank. However, there are some electric boilers on the market that have a storage capacity built-in, such as the Electromax, which provides both wet central heating and a hot water supply. Alternatively, if a storage tank is already in the property, the homeowner could make use of an electric flow boiler such as the Amptec. This can be installed in a convenient location without making any adjustments to the hot water provisions.

Build homeowner confidence Unlike in the gas industry, where there is a requirement for installers to be gas safe registered to install a boiler, there is no similar requirement for those installing electric boilers. Engineers can build confidence in their customer base by proving their competence by demonstrating membership of an electrical trade body.

Look for the label Before installing any electrical heating appliance, installers must prove that the appliance adheres to the relevant building regulations. Engineers are advised to look for a third-party electrical assessment label on the boiler – currently these are not mandated on gas boilers. This label will provide them with the assurance they need of the product’s construction, safety, quality and performance.

Assess the circuitry Checking the condition of the wiring is an important consideration for heating engineers, and it is particularly important in retrofits, as the circuitry may not be up to current standards; owing to their high-power usage, electric boilers need their own dedicated circuit. Importantly, to ensure a safe installation, the ratings of switches, such as isolators, must be considered and adjusted where necessary.

Flush the system As with any wet central heating system, it is an important requirement that you flush the system prior to the installation of a new boiler. This is because contaminated water currently in the system could contaminate the replacement heating appliance, impairing its performance. Once this has been performed, it is recommended that the installer adds an inhibitor to the system to protect against corrosion.

Read the instructions This might at first seem obvious, but less obvious is the need to read the manufacturer’s instructions with the homeowner. Much like any wet central heating system, the electric boiler will

be connected to controls, TRVs and a programmer. It’s important to have a conversation with the householder to explain how to control their new appliance.

Arrange regular service visits

In addition to the typical installation procedure, there are other factors that contractors need to take into consideration.

It’s important to remember that the end of the installation isn’t the end of a heating engineer’s role. It is best-practice to check the installation on a regular basis. The heating engineer should therefore arrange regular annual service visits to the homeowner’s property. This means not only checking the safety valves and ancillary components, but also the wiring should be checked for discolouration, which can occur if a connection has not been made properly or the wrong sized cable has been used.

A SMARTER FAN FOR A SMARTER HOME Modern homes are so well insulated that airflow within the property is more of a consideration than ever. With Addvent’s range of continuous fans, homeowners can achieve a constant flow of air with a trickle speed, which can result in a multitude of benefits.

M

odern dwellings are well insulated by design. In accordance with the newest legislation and energy efficiency trends, these homes sport low levels of heat loss and are not only good for the environment, but also for the family budget. The lack of warmth lost means houses can be warmed up more quickly, and they keep the temperature for longer. One side effect of adequate insulation is the lack of air movement. In older properties – especially in the ones with single glazed windows and non-sealed, laminate doors – heat (and therefore air) escapes through the gaps and through the thin material dividing the indoors and outside world. Air stays indoors in contemporary residences, and so does the moisture in the air. It can cause condensation which leaves walls wet, and can also lead to mould developing, in certain areas.

A fan that generates multiple benefits To overcome this challenge, Addvent – a leading provider of ventilation and fan equipment – is offering a new humidity stat timer controlled Enhance Axial fan. The quietest in Addvent’s range, at 15dB(A) in trickle mode, the fan provides continuous ventilation to any room; however, it is especially effective in bathrooms, wet rooms, toilets, kitchens or utility rooms with a boost function, either by a timer or now via the new humidity stat timer control option. The key application for the fan is for areas of poor air quality, or rooms with particularly poor air flow. The fan is designed to run continuously to keep homes fresh, healthy and free from condensation. This type of ventilation uses less energy than traditional intermittent fans, and is cheaper to run with a lower carbon footprint.

NEW “The Enhance Axial fan is highly efficient, consuming just 3.5W at trickle speed, with a boost speed option providing increased air flow by either timer or humidity stat control.”

The Enhance Axial fan is highly efficient, consuming just 3.5W at trickle speed, with a boost speed option providing increased air flow by either timer or humidity stat control. The fan is constructed using the most up-todate technology, and was designed to run all year around, 24 hours a day. It is compliant with System 3 of Part F of the building regulations, and offers the following added benefits: •F  ive-year warranty •L  ow energy consumption •M  odern, stylish and contemporary design

Keeping the noise down Noise is the hidden pollution of the modern world. We are surrounded with devices that constantly emit loud noises, such as hair dryers, food processors and vacuum cleaners, to name just a few. Constantly high noise levels are not only a source of annoyance, but can also cause hearing impairment, tinnitus, hypertension, ischemic heart disease and sleep disturbance. Switching traditional

equipment to quieter counterparts can drastically improve one’s health and general mood level. On trickle mode, the Enhance Axial fan is only 15dB(A) loud, making it one of the quietest fans in Addvent’s range. But exactly how loud is 15dB(A)? To put it in perspective, a faint whisper is around 20-30 dB(A) loud, so the Enhance fan is barely audible for human ears. Another key advantage of the new range is that the new products are also designed to comply with current ventilation building regulations.

TEST & MEASUREMENT

THERMAL IMAGING CONTINUES TO HIT THE SPOT Using thermal imaging to inspect solar panel installations can offer a wealth of advantages. However, there are a number of considerations that need to be taken into account to maximise their productivity. Joe Bishop of Test Meter explains.

S

olar panel installations are becoming increasingly popular from both a private, commercial and governmental perspective amid a fall in installation costs and a long-term price rise in non-renewable energy sources such as coal, oil and gas. However, solar panels require regular maintenance, which is where thermal imaging can provide an efficient solution to many of the challenges posed.

Choosing your thermal imaging camera All solar panels are glass plated, which causes a practical issue for thermal imaging as glass is not completely transparent in the infrared spectrum. Instead, a thermal imaging camera will only detect the temperature conditions of underlying cells through the glass screen, so thermal sensitivity of ≤80mK is required. For longer distance measurements, a high-resolution camera with a thermal resolution of 320 x 240 pixels or even 640 x 480 pixels should be used, and it is often appropriate to have a long-distance lens of 6˚ or 14˚. This is particularly useful when looking at panels installed on roofs, or other less accessible locations. Test Meter offers testers from a range of different companies, including the Flir E4 thermal imaging camera shown here

Pre-inspection conditions Solar panels are a common sight on rooftops and in larger facilities, such as solar farms. With active troubleshooting and proper maintenance, solar panels can produce electricity for many years, and a thermal imaging camera provides a great way of checking solar panels quickly. However, it is important to identify appropriate conditions before an inspection so that there is sufficient thermal contrast to locate faults. Solar irradiance levels – measurable with an irradiance meter – should be above 500W/m2, and preferably above 700W/m2, and the lower the outside temperature, the better. Damp or wet conditions will also adversely affect results, because water will cause false anomalies in a thermal image. Cloudy and windy conditions are also to be avoided if possible.

Before starting a solar panel inspection One of the great advantages of thermal imaging is that there is no need to disconnect solar panels whilst performing an inspection. Anomalies are clearly displayed on the thermal imager’s screen as part of a crisp thermograph that is relayed to the user in real time, although the user must set a manual range based on the highest and lowest temperatures on the solar panel, in order to emphasise

any differences across the cells. The actual temperatures can be determined using an IR thermometer. A peculiar property of glass is that emissivity depends on the angle of incidence from the position of the observer. Reflectance is higher at 90˚, so in order to avoid a reflection of the thermal camera and operator, the user should be at a maximum angle of 85˚. However, extreme angles lower than 30˚ result in too-high emissivity, so observations should be from a minimum angle of 30˚. That gives a 30˚

to 85˚ observation angle. To help negate the problems associated with frontfacing inspections, it is possible in some circumstances to perform an inspection from the rear, where there is no glass covering.

What to look out for Thermal imaging cameras are capable of showing a number of problems. such as defects in cells (impurities/gas pockets or cracks), temporary shadowing (dirt, pollution, humidity, bird droppings), defective bypass diode, or faulty interconnections.

“A thermal imaging camera provides a great way of checking solar panels quickly.”

SPECIAL FEATURE

Figure 3 – a ‘patchwork’ pattern which indicates a defective bypass diode.

Most problems will show as a hot spot or cold spot, although defective bypass diodes display as a ‘patchwork’ pattern. As these problems can clearly be shown on screen, it makes it easy to scan large installations quickly. However, thermography only provides indicative results, and a full electrical inspection must be carried out for confirmation. Nevertheless, thermal imaging is an excellent first port of call when checking new or existing solar installations.

TESTING TIMES Brendan Beaver, the UK Manager of electrical test solutions provider, Metrel, examines the benefits of the latest multi-function testers, and questions why users would want to pay for features that they can’t even use.

O

ver the years, there have been many versions of downloading test meters. However, despite the various promises of time savings – and reducing the risk of mistakes in transcribing the results from tester to paper, and then paper to certificate – they simply haven’t caught on. At Metrel, we believe this is because the manufacturers of these testers fail to put themselves in the minds of their customers and wrestle with the problems of using a downloading tester on site.

Right now, lots of electricians own – and use daily – testers that are capable of storing their test results. However, many find the features too complicated and long-winded to actually use, because they still need to make separate notes, on paper, about which circuit and board each test relates to, vis-a-vis the location in the tester’s memory. It is more practical for an engineer to fill out a copy of a certificate by hand, and then make a fair copy either in their best handwriting, or by typing it up into a computerised certificate when they get home. What a waste of their time.

The ideal testing method Ideally, what engineers need are testers that save the results and notes directly onto their testing device, without the need for pen and paper. This data would then be ready for sending to the depot, or alternatively, it can be quickly downloaded (without drama) on return to the office. The act of certification, though a vital part of the process, should not be allowed to become a drag on the completion of the job, or indeed, getting paid. This is not available when a conventional LCD screen is all that is provided, as is the case with an ordinary multi-function tester. This probably accounts for the fact that,

This simplicity is continued when the results are downloaded, quickly and easily via the USB port, into the full array of 18th Edition certificates, installation certificates, condition reports and minor works certificates. Is it any wonder that a high proportion of Metrel customers are using the results storage and download features of their testers? Established over 60 years ago, Metrel is one of the oldest manufacturers of electrical test equipment. The company continues to innovate, and produces test equipment for HV and LV applications, including power quality, earth analysis and transformer analysis.

though many downloading testers have been purchased, there are very few operators using the download feature. With the introduction of dot-matrix displays by Metrel, increasing numbers of users of multi-function testers like MI3152 and MI3155 are finding the ability to make notes using the touchscreen’s full keyboard allows them to leave the pencil and paper at home as they can annotate the results, as well as locations, within the circuit. The on-board fuse table and connection help screens, allied with the ‘pass’ and ‘fail’ indicators, give the operator confidence to pass the results to storage. Is there enough memory on board these testers to hand all the information, test results, test parameters and all the notes and comments on a real test site? The

answer is yes. With a class leading 8GB of memory, there is more than enough to satisfy your needs. Meanwhile, Metrel’s new memory management system and workspace management system is undoubtedly unique. Again benefitting from the dotmatrix touchscreens, it allows the operator to visualise the installation, building a hierarchy of objects or nodes, within a workspace, rather like you would on your computer; highlighting components with coloured icons, and making it easier to post the results to the correct circuit without writing anything down. Similar to a computer, it is very easy to copy and paste structures and clone test parameters from one location to another, saving time in building structures for testing.

TESTING AND INSPECTING – DON’T GET YOUR WIRES CROSSED Gary Parker, Senior Technical Support Engineer at the ECA, looks at how inspection and testing is changing in the wake of the 18th Edition of the Wiring Regulations.

T

he 18th Edition of the Wiring Regulations, which came into full effect this year, contains lots of subtle changes in wording as well as regulations being introduced for the first time, rewritten, or removed entirely. Some of these have especially important implications for inspection and testing. Designers and installers need to be fully up-to-date with these, to ensure they can continue to undertake tests and inspections safely and efficiently.

Part 6, revisited

which sees some content moved to highlight the ‘presence and adequacy of earthing and bonding arrangements’. Regulation 643.6 has introduced a new requirement to verify polarity at the origin, where relevant, before energisation. This is something that most contractors have done, but it is still good to see in the regulations.

Part 6, Inspection and Testing, contains some of the more extensive changes in the 18th Edition. It has been completely restructured to align the regulation numbers with the CENELEC standard. Chapters 61, 62 and 63 have been deleted, and the content has been moved to Chapter 64 (Initial Verification) and 65 (Periodic Inspection and Testing). The model forms of documentation in Appendix 6 of BS 7671:2018 have also been modified, albeit only slightly, with the biggest change being in the Minor Electrical Installation Works Certificate;

Is more complex RCD testing needed under the 18th Edition? The requirements for testing RCDs haven’t changed a great deal. There is a note in Regulation 643.8 that now states that RCDs up to 30mA can be tested at a current equal to, or higher than, five times their rated residual operating current. There is also more emphasis on different types of RCDs, particularly where there may be waveform distortions. EV charging and solar PV are good examples of this. Note that in some instances, these RCDs, often known as Type A, Type B or Type F, may not be compatible with some older models of RCD test instruments.

“Regulation 643.6 has introduced a new requirement to verify polarity at the origin, where relevant, before energisation. This is something that most contractors have done, but it is still good to see in the regulations.”

A word about certificates… The test certificates in the 18th Edition are not widely different to the 17th Edition models, but there are subtle changes on all of the forms. As such, any work being done in accordance with the 18th Edition commencing on or after January 1, 2019, should be, and should have been, certificated using 18th Edition model forms. ECA, eca.co.uk

Designers and installers need to ensure that they are fully up-to-date with the latest regulations to ensure safe and efficient inspections

For more information on these forms, other changes in the 18th Edition, and more resources, visit www.eca. co.uk/Project18. The ECA’s #Project18 campaign is a member-focused initiative that aims to raise awareness of the 18th Edition and to help members with the changes.

Super Rod’s CRSK Super Grips. The harder you pull, the tighter they grip

GET A GRIP ON YOUR CABLE ROUTING RODS Sam Horseman, Distributor Supporter at Super Rod, provides a series of hints and tips to help electrical contractors get the most out of their cable rods and attachments.

F

or almost 20 years, electrical contractors have been reducing the amount of time they spend on complex or fiddly routing tasks by using cable rods. A good quality rod set is a great investment, and one that will last a lifetime and solve any number of cable routing dilemmas along the way – as long as you use them correctly. Super Rod is a UK manufacturer of cable routing rods, and since opening for business in 2001, we’ve been providing contractors with an ever-expanding range of rods and attachments to help them with almost every conceivable cable routing task. To get the most out of these rods and accessories though, it’s important to know how they should be used properly – not only to ensure the job is done more quickly and with less effort, but also to keep your rod set in tip top condition.

Choosing the right rod for the job Our Adoxim rods are colour coded to indicate how flexible they are, with white being the most flexible, and black the least. They aren’t designed to have a specific purpose – i.e. a yellow one is for routing cables through a cavity wall – they are designed to give users five different flexibilities so that you have a variety of options in your arsenal when faced with a new installation task. Most contractors will have a favourite rod (normally the red one) which they reach for time and again, even when a more or less flexible rod could be more suitable. So before reaching for the tried and tested red rod, consider whether another flexibility of rod would be a better choice. As well as choosing a rod based on its flexible qualities, it’s also worth thinking about the diameter of the rod you select for a job, as this could also give you better

results. For example, a 6mm black rod gives more stability for longer runs, while a 5mm white nylon rod is better for routing cable through complex situations.

Connecting multiple rods together We are often asked whether there is an optimum order that rods should be assembled in when joined together for extra length, and the answer is, surprisingly, no. Most contractors will simply adapt the order to the needs of the job, usually with our most commonly used rod – the red 5mm – at the front.

Preventing rod damage

Most contractors will have a favourite rod which they reach for time and again – and it’s often the CR-RX5 red rod shown here

Considering short and long cable rods While most people think of cable rods as a tool for long runs, like rewires or running cables under floors or over ceilings, they are equally as effective for shorter, more complex runs – for example, in server rooms, data cabinets and for cable trunking installations. For these types of jobs, shorter polymer rods may be more suitable, as they are non-conductive and ideal for working around electrically sensitive materials and components. Like the longer cable rods, they come in a range of flexibilities and with an array of attachments, which can be used with all Super Rod products.

“While most people think of cable rods as a tool for long runs, like rewires or running cables under floors or over ceilings, they are equally as effective for shorter, more complex runs.”

Cable rods are designed to be resilient and robust enough for daily use. Ours are made from Adoxim 5, which is designed to resist abrasion and avoid splintering, but they are not indestructible, and damage can occur – particularly when they are overflexed. This happens most frequently at the joint, past a 90 degree turn. To avoid this common cause of rod damage, use a Flexi Lead and Domed Bullet to give you a start through a challenging angle, where a standard rod would be put under excessive pressure. Cable rods can also be damaged when the threads get contaminated with dust and debris, which clogs up the thread and prevents the rods from being joined together correctly. The Flat Bullet attachment can be used to clean out any contaminated threads to keep them in good condition.

A look at Super Rod’s CR-BX5 rod spare (black) in situ

Preventing cable loss Losing a cable in a hard to reach spot during the routing process is a real pain, so it’s understandable that many people use a bit of electrician’s tape to ensure their cable is securely fixed to the rod before threading it. Nowadays, we would recommend a pulling sock to attach the cable to the rod. It’s a really secure solution, quick to use, and you don’t need to cut the cable loose after pulling it through.

Preventing cable twist Twisted cables are a big no-no, particularly on Cat5 and Cat6 cable installations, as this can affect the overall performance of the installation. To stop your cables twisting while you pull them with your rods, try using a swivel rod which has a free-moving swivel end attachment that will dissipate any twists. It is also good for pulling cable off a drum or out of a box.

Choosing the right attachments Cable rod sets come with a lot of attachments, and understanding when to use each one will ensure you work more efficiently and effectively with your rods. The Chain and Super Magnet are a great attachment combination for routing cables through places with a lot of obstructions. Together, they give you the ability to route your rods from two different locations, through difficult routes, ultimately saving time. The Super Magnet can lift up to 2.5kg in weight too, so it can also be used to recover lost tools. Hooks are the simplest way of hooking a cable and pulling it to where it needs to be, while glow in the dark attachments are the ideal solution to get an indication of where your rods are in a dark area.

Maintaining your rods and attachments

Adoxim rods are colour coded to indicate how flexible they are. Shown here are the CR-YX5 yellow rod spares

We recommend that contractors use the Domed and Flat Bullet attachments to prevent dust and debris clogging up their rod threads, and regularly clean out any debris from their rods using the Flat Bullet. Rods and attachments should ideally be kept altogether in the robust tube packaging provided, or a carry case to keep them in good condition and to prevent rods or attachments from getting lost.

TOOLS & WORKWEAR

Solid Gear’s range of safety footwear seeks to provide options that are lighter, more breathable, and even more comfortable. Shown above is the Hydra GTX range

SPECIAL FEATURE

STEPS IN THE RIGHT DIRECTION Nick Thorpe, Category Manager for Solid Gear Safety Footwear at Hultafors Group UK, discusses the evolution of safety footwear and looks at the behavioural safety and materials technology influencing today’s designs.

S

afety footwear has evolved enormously over the last 200 years. While clogs and heavy leather boots were used by factory workers and miners in the 19th century, steel toe-cap and hob nail boots came to the fore in the first half of

the 20th century and army surplus footwear and rigger boots were some of the products used in the years that followed. Protective footwear has obviously moved on in light years since those times, but some of today’s poorly designed and non-compliant safety footwear is as uncomfortable and damaging as stiff leather hob-nail boots.

Footwear for the 21st century The design, development and manufacture of safety footwear in the 21st century is controlled by the regulatory framework provided by the European Directives for Personal Protective Equipment (CE EN 20345:2011), which ensures that every safety footwear product is designed to offer the right protection in compliance with these standards.

SPECIAL FEATURE

TOOLS & WORKWEAR

MATERIAL TECHNOLOGY AND DESIGN FEATURES TO LOOK FOR IN SAFETY FOOTWEAR Looking at three different types of safety footwear – the trainer, shoe and boot – these are the key components and design features to look for.

The safety shoe

The athletic safety trainer

The safety boot

Far from being conventional in its looks and just the kind of design wearers will aspire to, the newest products really are revolutionary for safety shoes. Something which, until now, has been impossible to get in a safety shoe is the E-TPU sole, which will deliver superb cushioning and comfort all day. In effect, it delivers a ‘bounce back’ which gives a 55% ‘energy return’ that will put a real spring in your step to reduce fatigue and stress on your back, legs and feet. This kind of shoe should have a stretchable upper with Cordura for water-resistance. This will also give amazing performance when it comes to breathability, fit and flexibility. Importantly, this kind of shoe should have a non-slip sole, plus a composite midsole and ideally a heel counter for foot stability. Naturally, the shoe has to have a toe-cap, but look for the new NANO toe-cap. It’s 40% stronger than fibreglass, lighter than other materials and thinner than other nonmetallic toe-caps.

Ideal for workers who are looking for something stylish and who are constantly on the move, this kind of safety shoe should have a lightweight athletic look and fully compliant safety features. The shoe’s midsole should be made of a poured PU rather than a traditional injected PU, to give a more cushioned feel underfoot, added to which a thick rubber outsole will provide a high level of anti-slip protection and durability. Furthermore, a BOA comfort fastening and lightweight, but durable uppers will deliver a better overall fit, making it easy to take the shoe on and off, especially when going in and out of people’s homes. The shoe should also have a fibreglass toecap which, with the ballistic midsole, will combine with the other protection features and anti-static properties to deliver S3 protection.

Given the wear and tear they have to put up with, feet deserve better than a cheap boot. Rigger boots might be easy to get on or off, but for maximum comfort, protection and durability, look for a best-in-class, technical safety boot that integrates modern design with best-in-class materials for water protection, comfort, durability and a sporty look. A waterproof and breathable Gore-Tex lining will keep your feet dry and comfortable, while a Vibram outsole and Cordura Ripstop fabric in the uppers offer great protection and ruggedness. A fibreglass toe-cap will also ensure fully compliant protection. Added to which, with the unique BOA closure system, pressure will be distributed evenly across your feet for maximum comfort and ensure a glove-like fit and keep them dry, warm and comfortable. Ultimately though, ensure you choose a boot that provides the wearer with the ultimate foot and ankle protection and support to reduce the risk of injury.

While governmental regulations control safety footwear design and development, product innovation is being influenced by advances in materials technology – the uses and applications of which, are being driven by behavioural safety and user attitudes to style, design and comfort. For the leading safety footwear brands, these are the key drivers in product design and development, as well as the fact that men and women have different on-site requirements. In recent years, there has been an increase in the use of ‘behavioural safety’ or ‘behaviour modification’ approaches to safety product development, which involve the clear understanding of, and defining individual attitudes to safe or unsafe behavior at work. For many employers, it’s a key issue, given that so many accidents and injuries are reported to be attributable to inappropriate or sloppy attitudes at work. In terms of the overall management of health and safety practices at work, effective behavioural awareness among the workforce – which comes from an effective understanding of health and safety issues – does reduce risk and injury.

“Given the wear and tear they have to put up with, feet deserve better than a cheap boot.”

Below is the Phoenix GTX - a technical safety boot that integrates modern design with water protection, durability and a sporty look

For safety footwear manufacturers, this issue is compounded by design and fashion influences. Comfort, aesthetics and style of products are key factors in encouraging workers to wear safety footwear – and, by association, ensuring they understand the benefits of keeping their feet comfortable and protected. It’s a highly efficient vehicle for increasing workforce participation in health and safety programmes. Thus, the resulting behaviour and individual actions can positively influence the overall health and safety culture in an organisation. For brand leaders, ‘Performance through innovation’ is a key philosophy in continually modernising safety footwear and satisfying not only regulatory requirements, but both end user and corporate health and safety needs.

Product development for a new age By using modern, high-tech materials in product design, 21st century health and safety is moving away from the old adage that high-protection safety footwear can come from simply having a ‘heavy boot’. Whilst there will always be ‘traditional’ work boots in any safety footwear range, the most modern safety footwear can be lightweight with sporty-looking designs if they’re made from state-of-the-art footbed materials complemented by the most modern technical fibres and quality materials in the uppers. “In terms of what inspires our product development, it’s ultimately the specific needs of professional craftsmen and women on site which have been thoroughly researched and tested”, says Nick Thorpe, Category Manager for Safety Footwear at Hultafors Group UK. “Our objective is simply to deliver the best quality safety footwear on the market. “That is why we work with suppliers known for their state-of-the-art material, such as Gore-Tex for water protection and

its ability to breathe, Vibram soles for grip and durability, the BOA Closure System for easy adjustments, and rip-stop Cordura fabric for hardwearing durability. “While quality materials and technologies are at the heart of our product range, product design and choice have to reflect the environments in which products are worn – whatever the working environment or weather condition – to deliver safety and protection wherever our customers are.”

HAMILTON EXPANDS WATERPROOF WIRING RANGE Hamilton Litestat has extended and made improvements to its range of Elemento weatherproof wiring accessories. Following enhancements, Hamilton now offers IP66-rated products that have been thoroughly tested to offer improved protection against water and dust ingress. Hamilton provides a total outdoor power solution, with its expanded range now including an uprated IP66 certified RCD unit. Its new, improved casing delivers complete protection against dust, ensuring the safe operation of outdoor equipment such as hedge trimmers and lawnmowers. In addition, Hamilton also introduces two new units to the Elemento range: a Retractive Switch and a Double Pole Switch. The Retractive Switch is a power-safe way for controlling garage doors and entrance gates. When fitted, the switch will automatically sit in the off position, and it must be pressed and held down to switch on and restore power to the circuit, illustrated by a red neon power indicator. This is particularly suited to garage door applications, where the switch is pressed until the doors are fully open. As per the rest of the range, it is IP66 rated and shares the same sleek Elemento aesthetic, which was introduced following a design refresh last year. Rounding out the Elemento additions, the new Double Pole Switch offers a maximum load of 20 amps – up from 10 amps for the standard rocker – to safely control higher demand electrical appliances and machinery. These new additions to the Elemento range are available now. For further information, visit hamilton-litestat.com

SELF TEST EMERGENCY LIGHT FITTINGS ESP continues to develop its Duceri range of emergency lighting, and the latest addition is a new range of Self Test Emergency Light Fittings, which offers numerous benefits over standard fittings by reducing the costs and time associated with manual testing and inspection. Whilst installing standard emergency light fittings is straightforward enough, the task of regularly inspecting every fitting on site for functionality, operation and duration can be an expensive, labour-intensive exercise. By opting for self test fittings, installers and contractors can save time and expense, with each self test fitting utilising an inbuilt processor to initiate ‘Self Tests’. Once an issue is discovered, the fitting displays the fault via the status LED. During initial power up, an automatic commissioning stage will begin. After the initial charge up time (up to 72 hours), the unit will carry out a full duration test. Once initial tests are completed successfully, the inbuilt processor will start the standard programmed test schedule, reporting failing functions via the status LED. For further information, visit espuk.com

RF REMOTE CONTROL FOR TIMEGUARD’S LED PRO Timeguard continues to improve its LED Pro range of outdoor LED lighting that enables installers to mix and match floodlights with their choice of plug-in PIR or photocell switches, and to build cost-effective master-slave installations with easy loop outs. The remote control fob is cleverly designed to be hand-held, or to fit behind a standard wall switch. It communicates with a dedicated 140W LED PIR detector, which can be used with any of the LED Pro range of black or white floodlights. The detector simply replaces the terminal cover on the floodlight and plugs in with no extra cabling required. Using cables that are supplied, the fob can also be wired in to a standard wall switch, enabling home owners to control the outdoor lighting using a wall switch but without having to do any extra wiring or redecorating. The remote control fob has a handheld range of up to 100m, and using it eliminates the need for a hardwired PIR override.

TRIDONIC SIMPLIFIES LUMINAIRE PRODUCTION WITH NFC TECHNOLOGY Contactless data transfer using Near Field Communication (NFC) is becoming increasingly popular in luminaire production, as programming driver settings using NFC provides significant time savings. With its own NFC-compatible software package, companionSUITE, and LED drivers with NFC interface, Tridonic is making it easier to switch to this pioneering technology. With the integration of NFC interfaces in LED drivers, contactless data transfer is now frequently finding its way into luminaire production. To be able to use NFC in the manufacture of luminaires, only one NFC antenna is required in the production area. NFC antennas are available as handheld devices and as NFC interfaces, which can also be installed directly onto workbenches. Since 2017, Tridonic’s companionSUITE software package has been available as a web-based tool for creating driver settings, programming LED drivers in production and, more recently, for analysing drivers of returned luminaires. This software package is compatible with common driver interfaces such as DALI, DALI-2, one4all and now NFC. For further information, visit tridonic.com
