Editor’s Viewpoint

The price is not right As we head towards the springtime season many families will be thankful for the lighter nights, warmer temperatures and general reason to save on energy bills, especially as a predicted 'cost of living catastrophe' threatens to bite much of the country.

Although the government has understandly focused its attentions on tackling the latest Covid variant and it's after-effects, a further blow to national morale has arrived with news that significant energy price hikes – caused by a number of global factors, including material shortages and market manipulation – will be arriving soon.

Indeed, with the price rises predicted to be as much as 50% for a standard household, the belt really will be tightening for millions of affected individuals, in turn diminishing the levels of disposable income that the public will have to spend on maintaining or upgrading their homes.

The knock-on effect from this will no doubt be felt by all trade professionals, who have benefitted from the savings that households have made from postponing holidays or being unable to take advantage of entertainment.

The major concern, of course, is that the price rises could prove a catalyst for what genuinely could become a cost of living crisis that may potentially throw millions into fuel poverty.

When you factor in the rising taxes that we'll all soon be hit with to help replenish the bruised and battered NHS, the picture looks pretty grim.

So what can be done to change course before we really do lurch into a crisis situation? In a recent statement, Luke Osborne, ECA’s Energy and Emerging Technologies Solutions Advisor, described three ways that the government can act in the short term:

electricity levies. Levies currently make up 23% of electricity charges and just 2% of gas charges. If these charges were reversed, it would be cheaper for households to switch from gas to electric.

1. Address the inequalities in gas and

Have a good month and enjoy the issue.

2. Reduce our dependence on imported gas. The government and industry need to invest heavily in new, renewable sources of energy immediately. This includes investment in flexible energy storage systems that will take pressure off the national electrical grid and make renewable energy more sustainable.

3. Reduce VAT on battery storage systems, solar panels, and heat pumps, to encourage uptake and make it even more cost-effective for households to make the switch to these technologies.

Of course, the ridiculous disparity in gas and electricity levies need addressing as a matter of urgency and could go a long way to easing the pressure.

The other two points are also very achievable but would require a mass implementation and education process that, although achievable in the long term, may not alleviate the short term financial issues that many are set to face.

Nonetheless, much of the advice that we have been given by top electrical industry authorities over the last few years regarding the need to embrace low energy consumption technologies and their importance in the future are now beginning to be proved correct.

And, if energy price rises continue to trend upwards, the skills and knowledge of electrical specialists who can install and maintain systems that take the strain off of the electrical grid will be in even higher demand.

Let's just hope the general public haven’t run out of money by that stage.

Digital member ID card launched by NAPIT NAPIT has introduced a new membership identity card App to make it quicker and easier for customers to verify the competence of members.

The introduction of the digital ID card makes NAPIT the first certification body in the electrical industry to offer this service.

Mike Andrews, CEO at NAPIT Group, says: “Our world today is undeniably one which is focused and reliant on digital technologies and advancements.

“With this in mind, we’re very proud to launch our digital ID app that allows our electrical members to access their membership ID card on-the-go via their smartphones, with or without internet connection.”

He continues: “As a business, we’re committed to enhancing safety and promoting competence in the sector.

The digital ID App allows our members to demonstrate their certification scope in a clear and easy way to their customers.

The additional benefit of a QR code on the card allows the customer to verify the members identity and competence enhancing this offering further.”

NAPIT services such as technical support and customer services are also easily accessible via the App. NAPIT now provides all its registered

electrical operatives with a digital ID card and understands that some of its members may need or want to carry a physical ID card as well. Therefore, it is providing them with the option of either or both cards via a new preference section within the members area on the NAPIT Online portal.

"NAPIT strives to serve the individual needs of members.

Providing them with both options, therefore, works to their advantage," adds Mike.

Corporate responsibility As well as the added benefits to members, NAPIT hopes that by making this switch the printing and postage of plastic ID cards will be reduced in line with its corporate responsibility to protect the environment.

Also, in order to speed up production, NAPIT has outsourced its physical ID card fulfilment to MBA, an established and progressive Document Management, Print and Digital Communications specialist, providing solutions for a number of known brands including National Trust, the NHS and United Utilities.

“We are committed to becoming a truly

sustainable business and we will continue to provide our customers with high quality sustainable products and services in ways to protect the environment and help reduce our carbon footprint,” says Mike.

If you are a NAPIT electrical member you will be invited to access the member portal giving you instructions on how to download the App and update your preferences.

The digital ID card App is now available to download on both the Apple App Store and Android Play Store.

NICEIC introduces new episodes of THE WIRE NICEIC is poised and ready to deliver an all-new series of the hit technical webinar series, THE WIRE. Covering the most relevant technical topics, upcoming episodes will discuss Maximum Demand and Diversity and Battery Storage.

Delivered via a new and improved browser-based platform, the 2022 series will also feature a newcomer, the NICEIC Pub Quiz, a fun interactive segment designed to test (and reward) the most technically advanced minds.

John O’Neill, NICEIC and ELECSA Technical Director, said: “When the pandemic in 2020, the world looked for quality sources of remote learning.

“Quick to respond, we doubled our efforts on THE WIRE to ensure our contractors had the resources they required and needed.” .

He added: “Since this time, we have broadcasted 48 episodes that have delivered over 40 hours of CPD Certified learning. Our live sessions attracted significant numbers and were often ‘maxed out’, while our on-demand service also attracted a large following.

“The combined result is one we are extremely proud of. Since April 2020, we have issued an impressive 69,000 personalised CPD certificates to our registered contractors. This is a fantastic number and one we are committed to exceeding in 2022.”

Thanks to a new and improved platform, the WIRE will no longer be restricted on numbers for live events.

Furthermore, the browser-based system will remove the need for any downloads, allowing viewers to access sessions directly via their web browser.

Add to this the ability to download CPD certificates straight after a webinar, and a raft of new in-session functionality, and it is clear the updates will enhance the viewing experience.

Free and exclusive to NICEIC and ELECSA contractors, registration for the 2022 series is open now.

JTL set to offer Domestic Electrician Standard JTL is continuing its work to support the changing needs of electricians as it plans to offer the new Domestic Electrician Standard.

Whilst the apprenticeship standard is still in development, JTL is planning to deliver the new Domestic Electrician Standard as soon as it becomes available, which is expected in late 2022/early 2023.

Designed to take a minimum of three years to complete, the new Domestic Electrician Standard is intended to culminate in candidates receiving a Level 3 Electrotechnical in Dwellings Qualification as well as a Domestic Electrician’s Gold Card.

The Domestic Electrician Apprenticeship Standard is intended to train domestic electricians in the best methods for the installation and maintenance of electrical services within domestic dwellings.

As part of this course, it is hoped that participants will have the opportunity to explore the use of low carbon technology within the home, potentially including the installation and maintenance of electric vehicle charging points and solar PV systems.

Liam Sammon, Director of Learning and Innovation at JTL (pictured), said: “As a not-for-profit learning provider, where all our funding is reinvested in apprenticeship training, we pride ourselves on being able to offer electricians and apprentices the most comprehensive and up to date training around – ultimately ensuring that safe working practices and high standards are upheld by our electricians.

“Given the growing interest in green technologies, JTL is highly conscious of the need to train our

Businesses urged to Make Tax Digital Businesses are being reminded to take steps to prepare for Making Tax Digital (MTD) for VAT before it becomes mandatory for all VAT-registered businesses from April 1st.

MTD is designed to help businesses eliminate common errors and save time managing their tax affairs. MTD for VAT is part of the overall digitalisation of UK Tax. In a recent independent study of over 2,000 businesses, 69% reported experiencing at least one benefit from MTD. These included preparing and submitting returns faster and increased confidence that they were getting tax right. 67% of businesses also felt MTD had reduced the potential for mistakes in at least one aspect of the record keeping, preparing and submitting returns process.

Around a third of VAT-registered businesses with taxable turnover below £85,000 have voluntarily signed up to MTD for VAT ahead of April 2022, and thousands more are signing up each week. Since April 2019, businesses with a taxable turnover above £85,000 have already been required to follow MTD, keeping digital records and filing VAT returns using MTD compatible software.

In July 2020 it was announced that all VAT registered businesses must file digitally through MTD from April 2022, regardless of turnover. HMRC is now reminding businesses below the £85,000 threshold of the steps which they need to take to be ready.

If businesses have not yet signed up to MTD for VAT, they should do so now to ensure they are ready in time for the April 2022 deadline.

National recycling award for Tamlite Tamlite Lighting has landed its second sustainability award in as many months after it was named winner of the Circular Economy Initiative of the Year at the Materials Recycling World (MRW) National Recycling Awards.

The awards are the most prestigious honours in the recycling and resource management sector, and recognise leaders and best practice within the waste and recycling industry, and further along the supply chain.

Named winner of the hotly contested category, Tamlite Lighting was shortlisted alongside 12 other organisations committed to the deployment of circular economy strategies.

Having entered the award in partnership with its sister company Electrical Waste Recycling Group (EWRG –

The Waste Experts), the award recognises the impact of Tamlite Environmental – an extensive luminaire, lamp, and electrical waste recycling service, which achieves a 98% recovery rate.

Judges noted that Tamlite Lighting had embedded circular economy principles into designing out waste and had identified ways to keep products and materials in use over a longer life cycle – thus resulting in a positive impact on the environment.

Debbie-Sue Farrell, Head of Wellbeing and Manager of Marketing at Tamlite Lighting, said: “We are delighted to have won this prestigious award and to be recognised for our sustainable business principles. Tamlite understands the value of a circular economy, and how it can

benefit people, the environment and businesses. By working in partnership with EWRG we’re able to offer our customers an unparalleled lighting recycling service.”

Tamlite Lighting was also named Sustainable/Ethical Manufacturer of the Year at the Insider Made in the Midlands Awards last year.

COMMENT

“THE OUTLOOK IS PROMISING” Mike Andrews, Chief Executive of NAPIT Group, reflects on some of the challenges and highlights of the past 12 months and looks ahead to the opportunities that 2022 has to offer.

T

his time last year I was looking ahead to 2021 and predicting a promising outlook for the repair, maintenance and improvement (RMI) sector despite the prospect of further lockdowns and disruption as a result of the on-going Covid situation.

Positive outcomes Whilst Covid undoubtably remains a concern, the demand in the RMI sector seen over the past year, despite the increasing cost in building materials, tells a very promising and positive story for the industry.

2021 was a year of growth and development for NAPIT – not only in our membership but also in the products and services that we provide to our members and to the wider industry.

Since the acquisition of FastTest Certification Software from Trimble in November 2020, NAPIT FastTest has been developed to offer clients much wider, on-site and desktop usability through the management portal, re-designed Mobile Application, Cloud-sync functionality, and access to a wider range of certificates.

In just 12 months, NAPIT FastTest is currently being used by over 1,000 businesses to generate a wide variety of certificates and reports in the industrial, commercial and domestic sectors.

As well as digital advancements, 2021 saw a step change in the wider industry focus on competence.

The introduction of the Electrotechnical Assessment Specification further tightened the entry criteria for businesses wishing to become registered with an Electrical Competent Person Scheme.

The Minimum Technical Competence requirements for all CPS providers are under review by the Department for Levelling Up, Housing and Communities and the Interim Industry Competence Committee was formed by the new Building Safety Regulator in anticipation of the Building Safety Bill gaining Royal Assent.

We welcome this focus and stand by our position that individuals working alone should undertake regular on-site technical assessments of their competence.

We continue to provide our support and expertise in these committees and reviews, and retain our focus on enhancing safety, compliance and competence throughout the sector.

It’s also been great to once again host physical events and see our members face-to-face. Our NAPIT EXPO events and presence at ELEX have been warmly received by customers and have given our team a boost.

A busy year ahead Looking ahead to the remainder of this year, we're gearing up to provide guidance to the electrical industry on the forthcoming Amendment 2 BS 7671. This will be the focus of our NAPIT EXPO events as we strive to deliver expert technical content and continue to support the on-going learning of our members.

As I look ahead to 2022, I do so largely with excitement. The previous two years have proved challenging, yet the construction sector remains strong.

With the move to Net Zero carbon emissions at the forefront of government policy, there is no doubt there will be an array of opportunities for additional growth, development and advancement within the sector.

COMMENT

Brett Smyth, General Manager of IDEAL Industries EMEA, is another that believes that there are opportunities aplenty for electricians in 2022: While 2020 will always be remembered as a year when everything suddenly stopped for a while, 2021 was a year characterised by frenetic activity as we responded to substantial and rapid demand as the world came out of hibernation.

Sites that were paused due to the pandemic were on catch-up programmes to complete, if not on time, then at least something close to on budget, which meant even tighter deadlines for electrical contractors.

Against that backdrop, contracting companies were still battling staff shortages due to COVID-19 and self-isolation regimes, alongside the loss of skilled EU operatives, which made catching up even harder.

Substantial product demand As a company that has always invested in product development that aims to enable faster, easier and more consistent electrical installations, at IDEAL Industries, we saw demand for our products rocket.

If 2020 was a roller coaster, then 2021 was a high-speed bullet train, and I am really proud of how our team managed customer service and order fulfilment to keep pace with the market.

It seems likely that skill shortages will continue into 2022 and beyond, and our approach to this at IDEAL Industries is not only to provide products that allow faster

“WE WANT TO NURTURE THE NEXT GENERATION OF TALENT” and more consistent installation, such as our FT-45 Feed-Thru modular plug system for data terminations and our new Gen II Wire Termination Connectors, but also to contribute to nurturing the next generation of talent.

Over the past year, we have extended our partnerships with FE colleges and sponsored social media influencer, Amy Barrett-Singh, as part of our commitment to supporting trainee electricians and encouraging greater diversity in the sector.

With face-to-face meetings now returning, we hope to introduce product demos and business coaching into this developing academy initiative.

Supply chain challenges have been another characteristic of the electrical marketplace in 2021 and this also looks set to continue.

At IDEAL Industries, we have excellent

UK stockholding capabilities and have re-shored our packaging production to the UK to reduce lead times, control costs and cut our carbon footprint.

We have also invested in stockholding in the Middle East to enable smaller orders and faster fulfilment from a dedicated facility in the region.

Rising to the challenges It is clear that 2022 will continue to be busy for the electrical contracting sector as people invest in their homes, kick start capex projects again and rise to the challenge of adapting commercial environments to agile working models.

Our goal is to help customers deliver projects on time by ensuring good availability across our range through both traditional wholesale and trade retail channels.

IDEAL STEPS UP SUPPORT FOR FUTURE ELECTRICIANS

I

DEAL Industries is continuing its commitment to nurturing new talent in the UK electrical sector by sponsoring the SPARKS Learner of the Year contest.

The move is part of a wide-ranging programme of product development and partnerships aimed at supporting electrical students and apprentices. The company’s activities already include product donations and demos for

colleges, along with safe isolation kits developed especially to support a safety-first culture for those training as electricians.

Silver sponsorship of the SPARKS Learner of the Year competition therefore reinforces IDEAL Industries’ support for the next generation of professionals and includes a commitment to provide a day’s training for the winner. IDEAL will also provide products for use in the competition.

SPECIAL REPORT

CLOCKING OFF The Electrical Industries Charity explains how it has used its expertise to help one industry professional to plan for a stress-free retirement.

R

etirement is a huge life change. It can mean slowing down, spending days in the garden, reading, golfing, cooking or it could mean looking after grandchildren, volunteering or learning a skill.

It is important we understand what funds we have for when we retire and how we can make the best decisions for our retirement, no matter if it is close or far away.

Jilly's story The Electrical Industries Charity recently supported Jilly, an office manager for an electrical distributor.

Jilly had worked in the sector for over 23 years and she contacted the EIC for information and advice regarding retirement. She had been thinking about retiring for more than five years but

because of issues with her mortgage and a recent divorce she had been unable to retire until the age of 68.

Jilly had recently become aware of an old employer’s pension and wanted to combine her private pension pot with her employer’s pension and her delayed state pension. She had carried out some internet research into combining her pots and managing her pensions but felt overwhelmed with the advice online and was unsure of a lot of its legitimacy.

The Charity Welfare team signposted Jilly to The Pensions Advisory Service (TPAS) which provides free, impartial guidance about pensions. TPAS cover all workplace, general, personal, stake holder and state pension schemes and can handle general and specific enquiries.

TPAS were able to advise Jilly on combining her pots and how to make them work best for her and her retirement plans.

The Electrical Industries Charity also advised Jilly to contact the governmental pension service as she had deferred her state pension for more than one year.

Managing the pennies Alongside TPAS and the governmental pension service, Jilly’s Charity caseworker also directed her to the Money Advice

Service – a free service set up by the government to help manage finances.

Here, Jilly could find an independent financial advisor to ensure her pension was working as hard as it could for her needs.

Preparing for the future With the help of a financial advisor Jilly is looking forward to a financially comfortable future. She has since downsized and is now living on the coast, a forever dream of hers.

The Electrical Industries Charity have now closed Jilly’s case and wish her the best of luck in her retirement.

THE

CODEBREAKERS ERIC: THIS PHOTO WAS TAKEN DURING A PROJECT TO CHANGE A KITCHEN INTO A UTILITY ROOM AND CLOAKROOM. LIGHTING CIRCUIT ORIGINALLY WIRED IN FLAT TWIN, NO CPC, LATER ADDITIONS IN T&E AND CPC BORROWED FROM A NEIGHBOURING CABLE. THE SHEATHING WAS ALSO REMOVED AND NOT WITHIN AN ENCLOSURE. WHAT’S ALSO NOT CLEAR IN THE PHOTO IS THAT THE LIVE CONDUCTOR HAD BEEN NICKED IN THE CUTTING PROCESS, LEAVING COPPER EXPOSED. Given the standard of work and lack of adequate enclosures, I’d like to think that this isn’t the work of a competent electrician. These observations tend to push towards a builder or a DIY modification instead.

The cable colours may date it pre-2004, but that’s not a given as older colour cables were still in circulation for a while after the change to the new colours.

There are several basic BS 7671 infringements here, and I’ll approach them individually.

Firstly, any connections or terminations in a cable and exposed single (basic) insulation must be taken into an adequate enclosure. On top of that, the inspector has stated that the Line conductor has been “nicked,” so there is possible access to live parts.

Any connections made must be mechanically and electrically robust and adequately supported so as to protect them from mechanical damage; it’s evident from the photo that this is not the case here.

As the modification work was made to a lighting circuit without a cpc, I’ll assume that the new work was carried out to a version of BS 7671 that required a cpc. This would mean the new work would need a cpc; however, borrowing a cpc from another circuit is not acceptable and means that the two circuits are no longer separate or individually isolatable, as they are now linked.

All in all, very sub-standard working practices, coupled with a lack of understanding of basic BS 7671 requirements, which could easily lead to a fatal incident.

Updated for BS 7671:2018, NAPIT’s EICR Codebreakers publication is purpose-written to aid contractors, inspectors and clients, and now includes updates to align with the 18th Edition of the wiring regulations.

GARETH VICKERS: I FOUND THIS WHILE CARRY OUT AN EICR. CLEARLY THERE HAS BEEN CONTACT ON THE EARTH BAR FROM THE LIVES, AND SOMEONE HAS ALSO REPLACED THE ORIGINAL SOCKETS WITH THESE – MUST HAVE BEEN A PLUMBER! Every electrician will come across this kind of issue at some point – new faceplates where the existing conductors won’t reach the new terminals.

To the competent, it’s a simple fix: extend the conductors in a safe way that doesn’t compromise the current carrying capacity of the circuit conductors or cause damage from improper termination.

It would appear the installer has failed on all counts here.

The Neutral conductor extension may not have an adequate current carrying capacity for the circuit, and too much of the un-insulated bare conductor is accessible.

Although long enough for the new terminal positions, the Line conductors haven’t been terminated adequately, and again too much un-insulated conductor is accessible.

In this case, the un-insulated Line conductors are touching the socket-outlet earthing bar when the accessory is pushed back into position, causing arcing and a potential risk of fire.

The Observations, Regulation infringements and Codes applicable to this observation would be: Current carrying capacity of Neutral conductor extension may not be adequate

THE ROAD TO NET ZERO

By Tom Gillam, Electrician Programme Manager at Schneider Electric

Smart homes: catalysts to empower change

T

oday, homes represent 20% of global CO2 emissions worldwide which is a sobering reminder that there is still a long road ahead to achieve our climate targets. To get to our Net-Zero goal, we must bring homebuilders, mortgage providers, homeowners and residents onside and empower them with the right technologies and solutions to help fight against climate change.

As more and more smart home devices are powered by clean electricity – from heating to cooking to personal transportation – we have an opportunity to decarbonise our dwellings at pace without changing our digital and connected lifestyles. This is now possible through cutting-edge technology and innovation, with positive, sustained change truly starting at home.

Smart homes The increase in electric vehicles could double residential energy usage, potentially becoming one of the biggest changes since electricity was first widely used. Add to that electric heating and cooking and the residential market will be severely disrupted. The time to act is now.

By 2050, households are expected to be the single largest consumer of electricity and the biggest contributor of CO2 emissions, with 34% generated by homes. We know consumers want to make changes and we need to empower them to do so by putting them in the driver’s seat when it comes to sustainable living.

Our Powering Change report discovered that 50% of Brits think it is important to make their home carbon neutral within their lifetime, and 66% consider sustainability to be important when making home improvements.

The majority (84%) are also concerned about rapidly rising energy bills should global temperatures increase by more than 1.5˚C. There are 30.1 million homes across the UK and Ireland today, and we're going to have to retrofit 26.5 million of them to meet targets. Our current progress is too slow. Currently, around 12% of homes globally are smart – but smart doesn't mean sustainable. While the number of smart devices in our homes has dramatically increased, the well-being of the planet has not.

Bringing Net-Zero homes closer with Wiser Heat We know we all must do more to understand and manage our energy use through technology – from plugs and sockets to electric ovens and EVs – but it can be difficult to know where to start.

Wiser Heat offers the ideal foundation for a more sustainable future. It allows users to switch heating on or off from a smartphone App, heat only specific rooms, and utilise self-learning features to avoid wasting energy.

The multizone smart heating system helps to drive energy bills down, makes homes more comfortable for residents, and increases a home’s sustainability. It’s a quick and simple way to begin adapting for a more planet friendly lifestyle.

To achieve our Net-Zero targets, there needs to be more emphasis on retrofitting existing building stock, with incentives – helping to save energy, alleviate fuel poverty, and make households more sustainable. We also need to create minimally acceptable standards for all buildings, old and new.

Finally, we need to find new ways of delivering sustainability by leveraging existing technology, both digital and electric.

This article from the experts at NICEIC looks at the installation of wireless smart devices and aims to provide guidance to the contractor when installing such types of devices.

RETROFITTING FOR A SMART HOME 24 February 2022 PROFESSIONAL ELECTRICIAN

any new installations include the provision for smart control, typically installed during the initial construction, based on a system-Bus type configuration using multi-pair or data networking cables.

However, increasingly, home owners are requesting the retrofitting of wireless smart devices within older properties as a means of providing smarter and more convenient control of lighting, heating and security monitoring.

Regulation 537.3.1.3 of BS 7671 permits the use of functional switching, including smart devices, which interrupts the current using semiconductors.

Typical devices consist of an in-line module placed in the circuit between the supply and the equipment to be controlled; for example, between the switch and a group of luminaires. Most offer the facility for dimming and integrate timing functions; additionally, with the option of changing the colour rendering index (CRI) of the light output, depending upon the type of luminaire installed.

Having such functionality provides the means to set up lighting scene scheduling usually through an app with a tablet, phone or other hand-held device.

Other devices such as an in-line relay controller, typically rated up to 16 A, are capable of switching larger current loads, usually associated with a radial circuit, with some offering the facility for live energy monitoring.

Many manufacturers are now incorporating smart control features within their products; for example, within external passive infra-red (PIR) detectors, LED flood lighting, various lamp types and smoke/heat detectors.

024_PE_FEB22_Layout 1 12/01/2022 10:26 Page 33

However, with so many smart devices available having varying operational characteristics and setup configurations, this could lead to issues with compatibility when attempting to synchronise and operate multiple devices in the home, consequently affecting the ability of low voltage circuits to operate as intended (Regulation 512.1.5). To minimise the risk of this happening, manufacturers’ instructions for compatibility should always be carefully considered at the design stage.

Accessibility Smart devices used to control luminaires are often small and designed to fit within a confined space, such as within switch boxes or in a ceiling space adjacent to the luminaire. However, when installing such devices remote to the item of equipment to be controlled, only those devices which are indicated as suitable for their installed location according to the relevant product standard, as shown in Table 55.3 of BS 7671 should be used (Regulation 559.6).

Provision of suitable access arrangements to facilitate subsequent inspections and maintenance must be provided (Regulation 513.1).

Where it may be difficult to identify the purpose of switching devices or control gear used for smart control a suitable

Fig 1. Commonly used smart devices

means of identification shall be provided (Regulation 514.9.1 (iii)). Recording the location of such devices used within the installation on a certificate or accompanying drawings may be appropriate.

Control Many low energy networks require a coordinator device, typically a hub or a controller usually connected directly to the router and Local Area Network (LAN), as shown in Fig 2. The hub is the root of the network providing a communication link between paired ZigBee, Z-Wave and other similar types of smart devices; and is usually the first component to be set-up during the initial installation of a smart home prior to connecting other devices.

The hub holds data relating to the LAN, such as its IP address, which provides the gateway for granting access to the hub’s network while remote from the home. The hub also provides a security centre for the

Fig 2. Smart hub controller with inbuilt Zigbee, Z-Wave and Wi-Fi communication protocols

connected smart devices.

Some manufacturers producing equipment with inbuilt ZigBee and Z-Wave protocols are starting to introduce controller hubs allowing communication across multiple platforms from different manufacturers.

As an example of the type of control available, the activation of an external PIR flood light integrated with Z-Wave communication may instigate a direct signal back to the hub (if in range), or through other connected smart devices on the network prior to reaching the hub. This may then enable designated lighting within the house to switch on and, in addition, send a notification to a phone alerting the user that an activation has been detected.

Summary The use of smart devices within older properties is becoming a popular choice with home owners as a means to achieve greater control for energy efficiency and improved security.

However, with so many products available great care must be taken when selecting smart devices for a particular project. The risk associated with compatibility between devices from different manufacturers and that of other equipment used around the home may impact on the reliability of low voltage circuits to operate as intended.

To mitigate any risk manufacturers’ instructions for compatibility should always be considered.

We made a significant investment in new testing equipment and a cutting-edge photometry luminaire testing scheme in 2020, to bring our light testing facility in-house. We purchased our own Goniophotometer device and signed up to the Gonio photometry luminaire testing scheme, which was created by the LIA, together with its partner Acal BFi, to enable lighting manufacturers to offer efficient third party certified luminaire performance testing.

As well as radically speeding up the testing process for Ovia’s lighting products, the scheme also offers reassurance when it comes to validating photometric measurements such as Lumens per Watt and related performance claims. It gives us the ability to scan light sources and luminaires quickly and simply, and create quality, easy to understand light measurement data.

Full photometric scans can take from as little as two minutes and, once ready, the data is sent securely via a dedicated cloud server to the LIA Laboratory for validation. The LIA Laboratory will then be able to issue third party reports without the need for product samples to be transported around the country or the world.

As well as providing upfront validation of the performance of new products being developed, it is also vital to ensure that further batches of products being brought in are guaranteed to be of the same consistency in performance and quality.

In recognition of Ovia’s laboratory facility, we've recently been awarded LIA Laboratory certification.

Dr. Zzeus

IN THIS REGULAR COLUMN, ‘DR. ZZEUS’ TOM BROOKES, md of zzeus training and CHAIRMAN OF THE FSA, WILL ANSWER YOUR QUESTIONS RELATED TO FIRE SAFETY COMPLIANCE. I've been told that all electrical circuitry needs to be checked with an insulation resistance test instrument every five years which would require the removal of every device such as detectors, call points and sounders. Is this correct?

The short answer is that BS5839-1:2017 does not require an insulation test every five years. The British Standards requirements are as follows: 1. Periodic testing BS 5839-1 does not have any requirement for insulation testing at a five-year period, Additionally, the 18th Edition of BS 7671 makes it clear that the periodicity between inspections of electrical installations is a matter of assessment by the inspector.

Concerns the inspector would consider include: ● Regulations and legislation, any licencing requirements and insurance obligations, as well as an assessment on the deterioration of the electrical installation. ● Dismantling of the system is to be avoided during scheduled maintenance and servicing. ● Fire alarm final extra low voltage (ELV) circuits from the CIE are all wired in fire-resisting cable which is continuously monitored for faults by the CIE. The low

voltage (LV) mains cabling is not continuously monitored and must be assessed as part of the general electrical installation.

2. Initial Installation of fire alarm and detection cables At the initial installation of any fire alarm and detection system cable Clause 38.1 states: All installed cables with a manufacturer’s voltage rating suitable for mains use should be insulation tested at 500 V d.c. Prior to this test, cables should be disconnected from all equipment that could be damaged by the test.

Insulation resistance, measured at testing, between conductors, between each conductor and earth, and between each conductor and any screen, should be at least 2 MΩ.

Control and Indicating Equipment (CIE) typically have fault sensing for wiring insulation resistance to earth. If this is set at 1 MΩ, the combined effect of all wiring earth insulation resistance ought to be well above this to prevent nuisance fault indications.

For substantial systems, this 2 MΩ minimum needs to be significantly higher than this to attain somewhat in excess of 1 MΩ overall. For a small non-addressable system, 2 MΩ might be acceptable.

Earth continuity and, for mains supply circuits, earth fault loop impedance, should be tested to ensure compliance with BS 7671.

The following tests below should be carried out on completion of the installation work: ● Where maximum circuit resistance for any circuit is specified by the manufacturer or supplier, measurement of the resistance of every such circuit should be taken. ● Correct polarity of all circuits is checked where this is required for correct

28 February 2022 PROFESSIONAL ELECTRICIAN

monitoring (Assure operation of any manual call point while all detectors on a circuit are removed). ● The findings of all tests should be documented and presented to the company or person responsible for commissioning the system.

Any other checks stipulated by the manufacturer of the system must also be carried out at this point. On the model Installation certificate in Annex G of BS 5839-1 it clearly states that the tests in accordance with Clause 38 have been carried out and results provided to the commissioning person.

It often surprises me that many fire alarm and detection companies do not carry out any insulation and continuity tests on cables at installation.

This seems to have stemmed from some of the fire trade associations historically carrying out theory training on fire alarm and detection systems but with no knowledge on the required electrical training and testing.

BS 5839-1 is clear on insulation and continuity testing, and if we do not train technicians how to carry it out, it will not get done.

SNAKES AND LADDERS

In the first of a two-part series of articles, Technical Events Manager and Technical Author of NAPIT On-site Solutions, Paul Chaffers, takes a closer look at some of the important design considerations for cable ladder and tray systems.

I

n some of our recent articles for Professional Electrician, I've looked at installation requirements for conduit and trunking systems.

In this article, we take a look at cable ladder systems and cable tray systems.

Ladder and tray systems differ slightly from conduit and trunking systems in that they are not enclosures, and they do not provide mechanical protection, only cable support.

This means that the installation of non-sheathed conductors is not permitted as this would breach Regulation 521.10.1, which requires non-sheathed cables to be

enclosed. Consequently, only cables where mechanical protection is provided by a suitable sheath, for example, PVC sheathing or steel wire armouring, can be used in conjunction with ladder and tray systems.

Structural considerations Often, cable ladder or tray systems are installed to carry only light cable loads.

As they are generally of steel construction, this is usually enough to carry the load without too much concern (providing suitable supports are in place).

The cable tray is available in different widths and heights, where information on levels of deflection can be obtained directly from the manufacturer. Deflection is the degree to which a structural element is displaced under a load and can be reduced by the correct positioning of supports.

Where heavy cable loads are expected, a cable ladder system often provides a superior solution and greater flexibility as it can be built and mounted in virtually any position.

Ladder systems also minimise the number of supports needed due to the sheer strength of their design, meaning they can span greater distances between supports. It is not uncommon to find a

30 February 2022 PROFESSIONAL ELECTRICIAN

mixture of both systems that cater to different wiring routes and cable loads throughout a building.

Although very similar in looks, cable ladders should not be confused with actual ladders used to gain access. Cable ladders should never be climbed or walked on as this may cause personal injury, damage to the cables, or the system itself – see Fig 1 for clarification.

When fixing supports to the structural elements of a building, such as steelwork and beams, it is important to check that they are able to carry the additional load.

Fig 2: Channel support components

This may involve consultation with the building designer, depending on the proposed load bearing requirements.

Channel support system Steel channel (strut) forms the basis of many wiring containment support systems. Struts are usually available with plain or slotted bases in profile sizes 41 x 41 mm or 41 x 21 mm and formed from either 1.5 or 2.5 mm thick steel.

The main components consist of: ➐

Steel channel sections (struts)

Channel nuts are provided with either long springs, short springs, or no springs to suit different applications, usually with M10 or M12 threads.

It is essential that channel nuts are tightened to the manufacturer's recommended torque setting and the set screw is the correct length. It needs to screw completely through the nut (which is typically 6 mm to 8 mm thick).

However, set screws used for this purpose must not be too long; otherwise, they can bottom out on the channel before the screw head tightens down on the fitting. These individual component parts can be seen assembled in Fig 2, and their overall versatility is illustrated in Fig 3 as a completed system.

beam clamps may be used as appropriate, as in Fig 4 and Fig 5.

Where there are multiple levels of tray or ladder hung on the same rods, it is important to ensure that the safe working loads of the threaded rods and associated components are not exceeded.

Conclusion Hopefully, in this first part, the article has highlighted a few areas of design that require care and attention to get right.

Considering the sheer weight and complexity of cable ladder and tray systems, it is recommended to consult directly with manufacturers’ technical guides to obtain the required information to complete a safe and satisfactory installation. * NAPIT would like to thank Legrand for the source material used in this article

You ask: FOR YEARS I’VE BEEN USING AN OLD MULTIMETER FOR BASIC TESTING BUT IT DOESN’T REALLY DO EVERYTHING I WANT, LIKE MEASURING VOLTAGES HIGHER THAN 600 V AND CURRENT UP TO 100 A. CAN YOU SUGGEST A REPLACEMENT?

Megger says: It sounds like the new Megger MET1000 multitester is just what you need. It measures AC and DC voltages of up to 1000 V and offers non-contact AC current measurement up to 200 A. It will also check resistance/continuity up to 50 kΩ. A great safety feature is that it will warn you of dangerous test voltages, even if its batteries are worn out or not fitted. Other features include single-pole testing, in-rush current measurement and phase rotation indication. It provides true RMS readings and, if you use it on a circuit protected by an RCD or RCBO, it won’t trip the device. It’s got a large clear digital display for results along with a separate bargraph, and there’s a data-hold option which is very convenient when you’re working on cables that are hard to access. The main display is backlit and there’s even a bright built-in torch to help you work more safely in dark locations. If you want even more, the MET1000 has replaceable test leads, a CAT IV 600 V safety rating, and it comes with a handy belt pouch. You’ll wonder how you ever managed without it!

WILL WE SEE SPD USE IN ALL DOMESTIC PROPERTIES?

Scolmore Group looks at the ever-changing regulations regarding SPDs and ponders what the future might hold for domestic usage.

B

S 7671 is due for a second amendment this year and we currently understand SPDs are due for review. It’s proposed the current regulations are changed to simplify the process a designer completes to identify if SPDs are needed.

With this in mind, let's take a deeper look at SPDs and try to understand where the industry is heading.

Surge Protection Devices There are instances where a transient overvoltage is generated, and such overvoltages can be created from a variety of sources including: ● a lightning stroke close to overhead power lines generating an induced current within the conductors. ● a lightning stroke making contact with the general mass of Earth close to underground cables, thereby generating an induced current within the underground cable conductors. ● induced emf within conductors caused by the switching of highly inductive loads.

What is an SPD? Taken simply, an SPD is a special kind of device which protects electrical equipment, wiring, and accessories from electrical power surges by shunting current to Earth within milliseconds. To do this, SPDs typically make use of two technologies:

a) spark gap b) varistors SPDs make use of spark gap technology to detect a transient overvoltage and start the discharge process. The generated arc is then

channelled into an arcing chamber which allows the arc to be split up into several small partial arcs. This type of technology is typically found in Type 1 SPDs. SPDs also make use of the qualities of a varistor (voltage-dependent resistor).

Varistors have a high impedance under

PROFESSIONAL ELECTRICIAN February 2022 35

035_PE_FEB22_Layout 1 12/01/2022 12:31 Page 48

TECHNICAL & TRAINING

normal operating conditions; however, when a transient voltage appears its resistance reduces, causing excess current to ‘shunt’ to Earth. When the transient overvoltage is removed the device returns to its typical high impedance state.

There are three ‘Types’ of SPD classified according to their standard: Type 1 – typically installed at the origin of the installation and usually operate on ‘spark gap’ technology.

Type 2 – typically installed at distribution boards and operate on varistor technology.

Type 3 – typically installed local to connected equipment.

Reason for their introduction It has taken some time for SPDs to become common within the UK. The initial reluctance of the contracting industry in installing SPDs was due to the perceived relatively low level of risk of transient overvoltages due to lightning strokes and the limited likelihood of damage to connected equipment.

However, it has been commonly accepted that with the increase in the cost of equipment and appliances installed the impetus for the use of SPDs has, correspondingly, increased. An installation protected by suitably selected and erected SPDs will be able to limit the risk of damage to connected equipment caused by a transient overvoltage, potentially saving thousands of pounds.

Based on the draft for public comment (DPC), there are two conditions where SPDs will be required:

a) where there is a risk of serious injury to, or loss of, human life, for example a safety service. b) where there is significant financial or data loss.

In all other instances Regulation 443.4.1 recognises that protection against transient overvoltages using devices such as SPDs, is reasonable, unless the owner of the installation declares it is not required due to any loss or damage being acceptable.

BS 7671 There are a significant number of regulations detailed within BS 7671 regarding SPDs. Other than the general requirement for overvoltage protection in Regulation 443.4.1, Section 534 (along with the informative Appendix 16) details the specific requirements for the designer and installer to consider when specifying SPDs. Regulations 534.4.1.1 details the locations where SPDs are required.

Type 1 or Type 2 SPDs should be installed at the origin of an electrical installation, while Type 2 or Type 3 SPDs installed downstream of the origin further protect against switching transients originating within the building.

It is permitted for SPDs to have combined classification, for example, a combined Type 1+2 or a combined Type 2+3 (Regulation 534.1).

The note to Regulation 534.4.1.1 states that Type 1 SPDs are often referred to as ‘equipotential bonding SPDs’ and are fitted to the origin of the installation to prevent dangerous sparking which might

36 February 2022 PROFESSIONAL ELECTRICIAN

lead to a fire or shock hazard.

It should be carefully noted that BS EN 62305-4 recognises that a Type 1 SPD will not provide effective protection against the failure of sensitive electrical and electronic systems and that subsequent Type 2 and Type 3 devices will be needed downstream of the origin.

The designer also needs to determine whether the SPD has internal overcurrent protection, otherwise there will need to be overcurrent protection with respect to short-circuit currents (Regulation 534.4.5.1).

Should the overcurrent protective device operate the installation will continue to operate but will not be protected against subsequent transient overvoltages.

A familiar sight SPDs will be a much more common feature within electrical installations and contractors will need to be familiar with the Type, application and protection necessary.

It is believed that the second amendment to BS 7671 will see stronger support for the use of SPDs in more installations, including safety services. If this is the case and the proposed change is included in the final document, SPDs may be needed in all domestic properties.

Scolmore will be looking to see if this change comes about and mandates the use of SPDs in domestic installations for the first time.

IS IT LIGHTS OFF FOR HALOGEN? Luke Osborne, ECA Energy & Emerging Technologies Solutions Advisor, takes us through the changes in regulations regarding the sale of halogen lamps and what this will mean for the wider industry.

T

he sale of most halogen lamps and lighting fixtures with fixed bulbs was banned in October of last year.

The ban was initially set for 1st September, but it was pushed back by the government’s Department for Business, Energy, and Industrial Strategy (BEIS).

The move should help to reduce our CO2 emissions by an estimated 1.26 million tonnes a year – the equivalent of almost 300,000 (fossil fuel-powered) cars, or 150,000 average UK homes.

However, there are conditions and exemptions to these new rules – for instance, the sale of fluorescent lamps won’t be banned until September 2023.

It’s vital, therefore, that ECA members and the wider industry fully understand these changes.

Contractors who tender for commercial refurbishments and lighting fit-outs stand to be particularly affected, as the ban will likely impact costings for work.

What exactly is being banned?

The regulations that govern the sale and use of halogen lamps and fixtures – Ecodesign for Energy Related Products and Energy

Information (Lighting Products) Regulations – have been updated to bring us in line with the rest of Europe, which banned the sale of Halogen lamps in 2018.

The types of lamps that are now banned can be seen in the chart (pictured below).

What are the exceptions?

The updated regulations will not apply to the following: ● ● ● ● ● ●

HL R7 lamps LED chips, dies and packages Emergency lighting Battery-powered light sources Original works of art Lighting for vehicles, transportation and military equipment ● Screens (monitors) ● Medical equipment ● Marine equipment Many signalling and control lamps, along

with high-power lighting products (theatre, sports, industrial lighting and specialist equipment) are also excluded from the changes in regulations.

Changes to energy labels As part of the updated Ecodesign regulations, changes to energy labels are being introduced across a range of electrical products, including light sources. A simplified scale will range from A to G, rather than A+++ to G-.

From May 2021, manufacturers have had to register their light sources (and other relevant in-scope equipment) in the European Product Registry for Energy Labelling (EPREL) database. Consumers and installers can scan a QR code on the new energy label to access additional information from this database.

IS R2 TESTING A DYING ART? Julian Grant, Managing Director of Chauvin Arnoux, ponders why electrical professionals don't undertake more R2 testing.

I

n many trades there is a natural tendency toward the long-established methods and techniques learned as apprentices that have been passed down from the generations that went before.

This is especially true for electricians.

While examples of the trade changing can be seen in some areas, like the wide adoption of ‘push-in’ style connectors over the old choc blocks, or the recent use of torque screwdrivers, very little change is seen in other areas.

One such area that we aim to address in this article is inspection and testing, specifically testing the continuity of protective conductors.

Two testing methods There are two methods for testing the continuity of protective conductors: a) the R1+R2 method, where Line and PE are linked, and b) the R2 method using a long wander lead.

Most electricians were trained religiously to undertake the R1+R2 method and only shown R2 as an option for testing protective bonding conductors.

This practice has become embedded, and many electricians now believe that R1+R2 is the ‘proper’ way to test continuity. The regulations, however, make no such statement.

40 February 2022 PROFESSIONAL ELECTRICIAN

Regulation 643.2.1 of BS7671 simply states that the continuity of conductors and connections to exposed-conductive-parts and extraneous-conductive-parts, if any, shall be verified by a measurement of resistance on protective conductors, including protective bonding conductors.

So, there is a requirement to verify the continuity of all protective conductors and their connections to exposed (e.g. metal light fitting) and extraneous (e.g. metal mains water pipe) conductive parts.

To achieve this in the majority of cases, it could be argued that the R2 method is much quicker, easier to carry out, requires little to no dismantling of the installation, requires no links to be added at the distribution board or in contactors etc., and if a suitable insulated pole is used, requires little working at height too.

Remember testing is for all connections to exposed and extraneous parts – R1+R2 testing at the end of the circuit only, although common, is not acceptable practice.

The practice of mass R2 testing has been around for a long time, but is usually only undertaken by specialist inspectors from testing companies who regularly performed EICRs on huge installations like hospitals, factories, and petrochemical refineries.

040_PE_FEB22_Layout 1 12/01/2022 11:15 Page 69

THE TRAINING GROUND DON'T SET YOUR APPRENTICES UP TO FAIL

To these inspectors, the idea of carrying out R1+R2 testing on such installations would be laughable, and the level of dismantling required would be almost impossible in many cases. This innovative practice from companies at the top end of inspection and testing demonstrates that there could be real benefits to those electricians working on a smaller scale, especially when carrying out EICRs. R2 testing method The method used to perform R2 testing doesn’t require every measurement to be made by trailing a lead all the way back to the MET (main earthing terminal) – a more practical step-by-step approach can instead be used.

Start by proving the earthing conductor and main protective bonding conductors and any protective conductors for submains. Then use these proven test points as a reference to test the final circuit CPCs and connections to exposed and extraneous conductive parts.

When the practice of mass R2 testing was first adopted, the testing companies mentioned earlier were using specialist bespoke poles and long wander leads not available to most.

But nowadays there are several manufacturers offering wander leads – you may even have one in your van that you use for testing protective bonding conductors.

It is even possible now to purchase comprehensive R2 testing kits, which include a wander lead with built-in continuity meter, belt harness and insulated pole. This type of kit makes large scale R2 testing a breeze and speeds up your overall testing time, and therefore profitability.

Having a continuity meter built into the cable reel means that the person doing the R2 testing is self-sufficient and your multifunction tester can be used to carry on testing other items, again speeding up the overall testing.

It is worth all electricians taking a closer look at the potential benefits of carrying out more R2 testing and with the new products available on the market, it will speed up your testing – especially when performing EICRs.

NET regularly speaks to apprentices after their AM2S to explore their experience, performance and how ready they were to take the assessment.

The number who tell us they were pressurised into taking the AM2S without being fully prepared seems to be on the increase.

Sending candidates for assessment prematurely can often be due to the training provider wishing to get the apprenticeship programme completed. However, taking the assessment before the apprentice is ready invariably leads them to fail, as they have neither the confidence nor competence to complete all the sections successfully.

So, what can you do to ensure this doesn’t happen to you and your apprentice?

The AM2S Checklist stipulates exactly the range of activities that should have been completed by the apprentice prior to the assessment. It must be signed by the candidate, training provider and employer to declare they have the required level of knowledge and practical skills in these areas before an assessment can be booked.

The importance of this checklist must not be underestimated – it is not a box ticking exercise. If the training provider asks you to ‘just sign this’ – please take a closer look.

You need to review each section’s content in detail and be honest: do you have the confidence in your apprentice’s ability to complete these tasks to a high standard? Do they have any additional training needs that need to be addressed?

As an employer, it’s your duty to talk to them and encourage them to speak freely about whether they feel ready for assessment. If they're not, push it back to your training provider and tell them they need more training and development.

Unless the checklist is completed honestly and accurately, the apprentice is ultimately being set up to fail.

THE CIRCUIT PROTECTION BOOM!

The team at Niglon look at some of the reasons behind the recent upturn in circuit protection sales.

C

ircuit protection devices are an essential part of every home, business or other building with electricity – so you’d imagine the demand for these components would stay fairly stable. And yet there’s been a huge uplift in sales of late: in fact, Niglon has seen a 62% increase over the past nine months alone.

When you investigate the factors leading to this upturn, there’s been a unique combination of new government guidelines and the global Coronavirus pandemic which have had an impact.

New landlord regulations The government has introduced regulations – which have applied to all new privately rented properties since June 2020 and existing property since June of last year – which ensures all landlords are taking precautions to protect their tenants.

The Electrical Safety Regulations require an inspection by a ‘qualified and competent’ person at least every five years, with the resulting inspection condition report being shared with the tenant – and, if necessary, the local authority.

The local authority can arrange for remedial work to be undertaken, if the tenant agrees and the landlord has not taken action; and they can then recover the cost of the work from the landlord plus a fine of up to £30,000.

So, how does this affect circuit protection supplies?

The vast majority of landlords will always have arranged regular inspections of their properties in the interest of safety (and resolving any issues at the earliest opportunity before they potentially become costly or dangerous problems) – but those who may have been less vigilant about the electrics in their properties are more likely to be arranging checks now, in order to avoid the potential financial

penalties associated with failing to comply with the new regulations.

More checks mean more potential issues highlighted – and with changes to wiring regulations also being introduced in the UK, it means new circuit protection devices are in demand.

18th Edition amends After a period of uncertainty, it’s now expected that the second amendments to the 18th Edition wiring regulations will be published on 28th March and will take effect exactly a year later. Previous updates have always included a transition

PROFESSIONAL ELECTRICIAN February 2022 43

043_PE_FEB22_Layout 1 12/01/2022 11:16 Page 48

PRODUCTS & BUSINESS SOLUTIONS

period of roughly six months, where any components designed before the specified date did not need to meet the new specifications.

But this time, the regulations have no such transition period so the entire supply chain is having to act much more quickly to ensure the changes are implemented sooner rather than later, with less than 18 months to go now until the introduction date.

The amendments are likely to see arc fault detection devices (AFDDs) required on all single-phase final circuits (not exceeding 32A) supplying socket outlets and fixed current-using equipment.

Development is well underway to ensure Niglon has an offering to meet the requirements ahead of the changes being implemented.

Previously, section 531.3.3 stated AC Type RCD could be used in ‘standard’ installations, with no clarification of what was meant by the term ‘standard’.

Once the amendments come into place, A Types must be used for all installations where there is a DC pulsated residual current, as they can detect and protect against the risk of electric shock.

Having reviewed the proposed amendments, Niglon halted production of its AC Type RCDs and is concentrating instead on production of A Type.

A clarification on section 536.4.202 also led to action for the Niglon team (again much earlier than needed, to ensure customers were well prepared for the changeover date). Previously, this regulation had stated the design current should not exceed the rated current of the assembly, with many contractors using diversity factors to calculate the correct selection of RCDs and switches.

As of the end of March, both RCDs and Switch Isolators must be protected by an Overcurrent Protective Device, selected according to the manufacturers’ instructions.

Since the clarification has been out for consultation, Niglon has been advising customers to only use RCDs within consumer units which have a current value equal to or greater than that of the electrical supply company’s upstream main cut out fuse. To that end, the 63A RCDs within consumer units were discontinued and production was moved to only 80A and 100A options.

Lifestyle changes Another major contributing factor to this boom in demand for circuit protection devices has been the numerous lifestyle changes which we’ve seen in the UK over the past few years.

One such change is the introduction of electric vehicles. While there’s not yet one sitting on the driveway of every home in the UK, electric and hybrid vehicles accounted for 10% of new car registrations in 2020 (according to Statista) and there are now 300,000 pure electric cars on the roads – and around the same number of hybrids.

There are more than 25,000 public charging devices for these cars around the UK (according to Next Green Car) and of course, many owners will have chosen

44 February 2022 PROFESSIONAL ELECTRICIAN

to install charging points in their own home for convenience – especially given the government grant available which makes this a more affordable option.

With a visit from an installer necessary, and the increased demand on the home’s electrical system, it’s inevitable that some electric vehicle owners will need to upgrade their circuit protection devices in order to make best use of an at-home charging point.

Soaking it up Another item growing in popularity while simultaneously adding pressure on a home’s circuit is a hot tub.

With sales increasing exponentially throughout pandemic lockdowns and beyond, and the hot tub seemingly being the new ‘must-have’ item for every home, again the extra capacity required to run them will have contributed towards the increased demand for circuit protection components.

Even for those who haven’t invested in a hot tub, Rated People report a 12% uprise in people renovating their homes last year – again, an activity likely to bring about the need for newer circuit protection devices, especially in older properties.

And while a new hot tub or some home improvements might have been a welcome lifestyle change for UK residents – there was another, much more significant, impact of Coronavirus as thousands more began working from home. While a proportion of these have now returned to their regular place of work, the added pressure on the electrical circuits of the nation’s residential properties will have no doubt been a factor in the uplift in sales.

The Office for National Statistics reported 35.9% of employed people did some work at home during 2020, compared to 26.5% in 2019. With some of these households seeing multiple workers now based at home, it’s hardly surprising to see some electrical components needing to be upgraded.

DON'T WORRY, BE HAPPY

How satisfied are the nation’s sparkies? We learn more about the best/worst parts of the job, according to a recent Draper survey.

A

new study from Draper Tools has revealed Britain’s electricians experience high levels of job satisfaction, with more than 80% feeling satisfied with their careers.

The news comes as Draper launches its new XP1000 range of VDE hand tools, featuring 21 pliers and 55 screwdrivers, plus sets of both and tethered plier options too. The company worked closely with the trade over a two-year period to develop the range, taking time to understand the highs and the lows of the industry along the way.

What satisfies sparkies?

When it comes to the two top reasons why electricians enjoy their jobs, it all comes down to a love of problem-solving and the satisfaction that comes with using tools on a daily basis.

More than a third of electricians feel like they’re providing a vital service, which contributes to their job satisfaction. A third also said they enjoyed travelling to

different locations for work. And just over a quarter cited the money as one of the most satisfying aspects of the job.

Commenting on the findings, Phil Rowley, Sales Director at Draper Tools, said: “As part of developing the XP1000 range, we spent a long time listening to the thoughts and feedback of the electrical trade. We worked closely with key figures in the industry to get our product offering right, but we also wanted to really get to know the sector and the people within it.

"We couldn’t help but be impressed with the passion and the pride electricians have for their work and this has certainly fed into the development of the range. It’s been a fascinating journey, getting to the heart of what matters to this vital sector.”

The tools for success Other reasons electricians love what they do included getting good feedback from customers, regularly interacting with a variety of people and how every day is different. A quarter cited the banter with

46 February 2022 PROFESSIONAL ELECTRICIAN

other trades as one of the things they enjoy about the role.

Tools of the trade are all part of the appeal too – a quarter of electricians said they get a sense of satisfaction from adding to their tool collection. And around 1 in 6 even admitted they get enjoyment from simply sitting back and admiring their tools.

Phil continued: “Of course, having quality tools is essential to doing a good job when you’re dealing with electrics. But we were bowled over by the amount of love and

046_PE_FEB22_Layout 1 12/01/2022 11:20 Page 47

pride people have for their tool collections.

“We hope our XP1000 range will go on to earn its place in the hearts of the nation’s electricians. The entire collection has certainly been a big investment for us, but we’re confident there is a lot to love about it. It’s reliable, comfortable, safe and comes with our Draper Expert Lifetime Warranty too.”

The recently launched Draper XP1000 range is tested to 10,000 V, suitable for use on live AC circuits up to 1,000 V and DC circuits up to 1,500 V, and fully compliant to EN60900 standards. It’s already getting great feedback from early testers of the range, with over 85% of them saying they’d recommend it.

Short fuse: the downsides of the job While there’s no doubting the love electricians have for their work, there are a few downsides. The biggest complaints were about rude customers and bosses. And more than a third of electricians get frustrated when those around them don’t understand the basics of how electrics work.

While some like the banter, 29% said dealing with other trades was one of the worst things about the job. Just over one in six cited poor workmanship by other trades as making their jobs worse.

Not being offered a hot drink on the job was also a common complaint from more than a quarter of respondents. There are some more serious concerns too: a small number of electricians worry about the daily risks associated with the job.

Some of the new products that a likely to become star performers during 2022 include: Floodlighting additions Inceptor Ace is a range of adjustable, LED asymmetric floodlights. Asymmetric floodlights are superior in concentrating light where it is needed by using reflectors to direct light in front of the fixture where illuminance is required. With symmetric floodlights, on the other hand, the light is distributed evenly in all directions.

The Inceptor Ace floodlights are IP65 rated and are available in a black finish, in 50, 100, 150, 200 and 300W versions, with 4000K cool white LEDs. They’re supplied with a 2 metre pre-wired cable flex for quick and easy installation, and a fully adjustable aluminium mounting bracket, which allows full control of the projection angle.

Photocell versions are also available, offering all the features and benefits of the standard fitting. The photocell versions turn the light on when the light level drops under 10-20 lux and turns the light off once the light level is over 30-60 lux.

Inceptor Murus is an LED wall pack with CTA Switch and a robust IK10 rated housing that makes it ideal in outdoor settings.

The IP-66 rated fitting is designed to be fast and simple to install and is available in 15W and 25W options and in a choice of standard, photocell and emergency versions. The photocell version can assist with energy saving by allowing the light to turn on and off at set lux levels. Inceptor Murus will turn on when the lux level is below 10-30 lux.

Installation of the Murus is quick and easy, thanks to the push fit/piano key terminal block and the floodlight can be Besa box or trunking mounted.

All models include a CTA switch, allowing the product to change colour temperature between warm white 3000K, cool white 4000K and daylight 6000K. It

is available in anthracite grey or light grey and comes with a five year warranty.

The Gator LED street lighting range with CTA switch and IK10 housing is ideal for lighting larger outdoor areas, such as car parks.

They are designed to be easy to install via toolless entry and offer 50,000 hour lifetime, 85˚ x 150˚ beam angle and IP66 ingress protection. The shorting cap can be replaced with a photocell sensor to offer an energy saving feature. Gator is available in a grey finish and comes with a five-year warranty.

New commercial products Added to the commercial offering is the Sprite range of recessed TRIAC dimmable LED downlights with CTA switch.

These IP54-rated aluminium downlights are supplied with TRIAC dimmable drivers which are pre-wired with a Fast Fit Flow connector or 3-in-1 multi-function dimming option for quick and easier installation. There are four sizes available – 3”, 5”, 6” and 8” diameter – and a choice of 13, 18, 25 and 35W versions, to cover a wide range of installation types and requirements.

E-Sprite is a range of recessed LED downlights with CTA switch. These eco commercial downlights are available in 9, 15, 25 or 30W versions. They are supplied with a CTA switch as standard and are pre-wired with a fast-fit Flow connector or 3-in-1 multi-function dimming option for quick and easier installation.

There have also been new additions to the amenity products section, including a range of new wall lights and ground lights.

Within the domestic section, new and improved versions of the popular Nano compact fire-rated LED adjustable and fixed downlight and the Inceptor Omni fire-rated tricolour dimmable downlight have been added.

The new Nano V2 and Omni V2 are supplied with push-fit Flow connectors which feature push-in, low maintenance

terminals to offer a time-saving benefit for installers. With the driver now incorporated into the Flow connector, this means that insulation can be laid over the fitting. Both also benefit from an improved lumen output.

Free lighting design service As part of Ovia’s commitment to delivering a first class service, a dedicated lighting design service is available, giving contractors access to free lighting design schemes for their commercial projects.

The aim of the free service is to provide expertise in choosing the right products and solutions to create a scheme that meets all the requirements and objectives of the project in question, and that is compliant with all the relevant regulations and standards.

With all the information gathered, including drawings and specifications, a Lighting Design Proposal will be prepared.

A schedule of lighting and lighting controls will be shared with the Ovia internal and external sales team who will then prepare a quotation.

The Lighting Design Proposal and prepared quotation will be sent back to the Ovia sales team member, and the quote will then either go through the wholesaler of choice, or the enquiry will be directed through one of Ovia’s supporting Elite stockists. If drawings are not available, Ovia offers site surveys through its external sales team.

TRENDS LIKE THESE Jacob de Muijnck, Managing Director at Gira UK, unveils the latest automated systems and technologies that will enhance the home in 2022.

T

he last two years have seen us all spend more time at home, so it’s no surprise that we want to make our personal interior spaces as comfortable and versatile as possible.

This is where the “connected home” has come to the fore, equipping the modern home with smart functions and devices that are specifically designed to improve daily life and contribute to a more efficient household.

In fact, UK consumers are now very familiar with smart TVs, fitness trackers, voice-activated assistants and 24/7 access to all kinds of media, and this has become part of everyday life as the features and benefits appeal to multiple generations.

The global health crisis and inevitable after effects have only highlighted that we need reliable systems in order to stay in touch with the outside world anytime, anywhere.

With this in mind we believe that there are three key smart home trends that are set to redefine the idea of a ‘connected home’ this year and beyond:

1: The home office that thinks for itself Fewer people leave their house to go work and the concept of working from home has become increasingly mainstream. But digital tools and services alone are not enough to maintain a high level of productivity.

A home office requires a healthy, well

considered environment that keeps you focused and motivated and so premium manufacturers are creating innovative solutions for the connected home office.

Innovations include clever chairs and desks reminding you to stand up, multifunctional charging stations for mobile devices and smart lighting and blind systems that adjust room brightness according to the time of day or work discipline under way.

2: Smart appliances for easy living From stoves that won’t let anything burn to bathrooms that know how you like to shower in the morning – intelligent technologies make life safer, easier and more energy-efficient.

Automated vacuum cleaners, washing machines, and dryers are only the first steps towards a connected home in 2022, with indoor greenhouses becoming increasingly popular as we bring the outdoors inside.

More smart devices are compatible with IFTTT (‘If this then that’) technology, which makes it easy to configure individual systems where products from different manufacturers need to work in-sync. For example, you can switch off multiple electric appliances with just one command before stepping outside – to save energy and prevent accidental short circuits.

3: Connected smart home concepts are in demand

Single, standalone applications are giving way to sustainable all-inclusive solutions as architects and builders consider the digital infrastructure and connectivity of living spaces early on in the planning phase.

Lights, blinds, heating, entertainment systems, security systems, home gyms and electronics, along with smart tools and appliances, can be controlled via one central unit in connected homes, adding luxury and a touch of design exclusivity.

Connected living is easy to facilitate, whether its a new build house or a renovation to an existing property.

Wireless systems such as Gira eNet SMART HOME communicate via radio transmitter – which means they can be retrofitted in both old and new buildings.

Thanks to a synchronised interplay of all components, your customer's smart home will do exactly what they need at any given time. Smart sensors, for example, react automatically to external factors such as ambient brightness, temperature, or humidity levels.

A RACKING IDEA

R

oof racks on commercial vans must be robust and durable. At the same time, a large carrying capacity is essential for any working environment. Being exposed to the rigours of the road and the outdoors, means that this equipment also needs to be corrosion resistant.

Strength and functionality To ensure maximum service life for roof racks, thorough durability testing needs to be carried out. This begins early in the design process; in-house engineers should utilise advanced analytical software to identify and eliminate any potential weaknesses.

Physical prototypes are then created and tested to destruction to ensure maximum strength in all areas. Continual improvement also needs to be carried out on existing designs too. This approach delivers highly robust roof racks with high load carrying capacities.

In some cases, this is even taken a step further. For example, Rhino’s AluminiumRack is independently crash tested to 20G at Millbrook Proving Ground in the UK – twice the industry standard city crash test of 10G. Its anodised aluminium alloy construction ensures durability and an

innate resistance to corrosion, delivering a long service life.

Roof racks must also be highly functional. Rhino ensures the usability of its roof racks thanks to a full width durable steel roller attached to composite stub axles, which allows for easy loading and unloading at the rear.

Aesthetics and aerodynamics Modern vans are starting to look more like passenger cars. Sleek lines and sharp details are becoming standard across all manufacturers, so modern roof racks need to match this design philosophy.

The AluminiumRack is designed to be sleek and smooth, seamlessly integrating with the aesthetics of modern vans.

Innovative features such as polymer composite nose cones improve aerodynamics and reduce wind noise while driving.

By selecting a roof rack with an aesthetic that closely matches the van, users improve the looks of a vehicle while also maximising aerodynamic efficiency.

Optimum fit Making sure a roof rack is optimised for the van model, wheelbase and height is imperative. A poorly fitted roof rack will not only look odd but offer reduced usability and safety. Choosing an optimised design

52 February 2022 PROFESSIONAL ELECTRICIAN

For the modern professional, choosing the best van roof rack from the wide selection available can be daunting.

So, what are the key characteristics to look out for in a quality product?

Rhino Products explores the important features. will also help ease fitting.

Rhino has designed the AluminiumRack to fit a wide selection of the most popular commercial vans, covering major brands such as Renault, Peugeot, Citroen, Volkswagen and Ford. A compatibility tool and comparison tables on the Rhino Products website allows customers to check that their van is supported and to select the optimum rack.

Bespoke installation kits tailored to each model and wheelbase deliver a perfect fit. Each kit includes instructions, all necessary parts and two Allen keys – with two ladders and two 10mm/13mm spanners (depending on the rack) required to complete fitment.

Designed for efficiency Improving fuel efficiency is a goal of all van fleets. Additionally, to help minimise environmental impact, many fleets are going electric.

Whether fully electric, hybrid or combustion only – choosing a roof rack which has reduced weight and good aerodynamic properties helps to maximise range and fuel efficiency.

TAKE THE FAST TRAK

We take a step-by-step look at the time-saving Fast Trak from Gripple, used in the suspension of electrical and mechanical services.

F

ast Trak is the suspension solution from suspension system manufacturer, Gripple, specifically designed to save time and labour in commercial and residential building projects. Tests have proven it to be up to six times faster than traditional channel and rod methods.

Using a trapeze bracket system, Fast Trak installations can be completed faster, smarter and without tools. Adjustments can be made in-situ with the bracket easily moving up and down its tracks during installation.

The range is particularly suited to areas with restricted space and includes side-loading and low-profile brackets to enhance the versatility of the products.

The lightweight pre-fabricated kits arrive on-site, making them easier to deliver, handle and store. The need for large areas to store long lengths of channel and rod is eradicated.

Fast Trak is also BIM-ready and fire tested, coming with the added reassurance of the Gripple technical team that is on hand to answer any questions.

HOW TO INSTALL FAST TRAK IN FIVE SIMPLE STEPS Step 1: Marking positions for the installation of tracks Using the indicators at the ends of the bracket, offer up the bracket to its final mounting position and mark the fix points in the indent at each end of the bracket.

54 February 2022 PROFESSIONAL ELECTRICIAN

Step 2: Fixing the tracks Drill holes where fixing points have been marked.

Then secure the tracks to the ceiling through the 10mm hole on the fixing tabs, using concrete screws or anchor bolts. When installing the tracks, the fixing tabs should be outward facing. Ensure the two tracks are parallel to the run of electrical containment.

HE'S IN FASHION! This month George Robertson gets to slip into some of the latest 'hero' garments from the Snickers Workwear collection. We get his thoughts.

I

f, like me, you spend two thirds of your waking life in your workwear, it's absolutely essential that you find a brand that you can trust to keep you safe and comfortable throughout the working day.

Until recently, I’d always been under the impression that workwear was much of a muchness and that turning up looking presentable is all you really needed to worry about. The workwear that I’ve been testing from Snickers has completely changed my outlook!

Amongst the items I was given to trial was a pair of Snickers' popular FlexiWork trousers with detachable holster pockets.

Comfortable, well fitting, flexible, hard wearing and with more tool pockets than you can shake a stick at, I've found these work trousers to be a revelation!

As it says on the tin, the holster pockets are detachable, with one zip and two poppers to a pocket. There are zipped vents on the thighs (handy for when you're working in a loft that's like a sauna), an internal belt that's tucked into the waist band, belt loops and a 'workwear toolholding system' point on

both sides of the waistband.

I’ve honestly never felt so comfortable in a pair of work trousers – no tugging at the waist to pull them up and no reason to tighten the belt every 15 minutes. Putting in and/or removing the kneepads is even more of a doddle.

Knee and easy Which brings me nicely on to the next item I was given – the 9169 D30 Ergo kneepads.

These are light and flexible but also impact resistant, making them suitable for work that involves frequent kneeling.

I was particularly impressed with the way they fit the FlexiWork trousers and I noticed that they ensure the user stays balanced when using them – particularly important when you're kneeling on a joist in a loft.

Another item I was given was the latest Snickers hoodie, made of an extra thick, soft brushed fabric. It’s warm and well fitting and the sleeves even have holes to poke your thumbs through, keeping your hands warm in the colder weather.

The hood will also keep that biting, cold wind away, even if you’re stuck in the

middle of a field, connecting an irrigation system or replacing all the pitch points in a caravan park.

Last, but by no means least, I was given a pair of Solid Gear Grit Safety Trainers to try out. Lightweight with a composite toe cap, these shoes fit me like a dream. They feature anti-slip and stability properties and are water resistant, yet breathable.

One feature I really like is the BOA fit system, which eliminates the use of shoe laces. Instead, you just slip the shoes on and turn the disc on the top outer of the shoe clockwise and the BOA system will tighten the shoe to a perfect fit.

When you're ready to take them off, you simply pop the disc up and the shoe will release.

As mentioned previously, this review has given me a bit of a wake up call when it comes to modern workwear and the comfort and safety levels that are achievable. I honestly didn't know it could feel so good to go to work!

SOLAR SO GOOD!

Reading taken from high voltage DC electrostatic grid

This month, Reece Hardy takes the Fluke 393 FC clamp meter for a test run.

T

he first thing I’d say about this clamp meter is that it is ultra-versatile! Designed primarily for professionals to measure solar installation voltages at the new standard of 1500 V, as well as other high voltage DC equipment, the Fluke 393 FC also offers the user the capability to take multiple readings – saving time by logging data for reporting at a later stage.

The unit is a decent size and came supplied with a carry case, set of CAT III 1500 V test leads, flexible current loop, magnet, strap and safety information

Reading (current/frequency) taken from incomer using flexible loop

booklet, so I was armed and ready to go once it arrived.

One of the main things to point out is the number of features that the tool offers, with functionality that enables the user to measure voltage/frequency, AC or DC current (including peak/inrush), capacitance, resistance (to 60k ohms), continuity and DC power. It also offers CAT IV protection to 600 V AC. A feather in the cap Fluke can add a further feather to its cap with news that the 393 True-rms solar clamp meters are the world's first to be rated at CAT III/1500 V DC according to the latest safety standard for clamp meters IEC/EN 61010-2-032:2019.

In use, I found the product easy to operate and it didn't take long to pick up on the functions and features.

In addition to the usual front clamp, an extra rear clamp loop can be added so the operator can take those awkward reading inside enclosed spaces like UPS or battery frames. An extra set of test leads is also supplied for additional readings like DC/AC voltage/frequency.

The meter is robust yet comfortable to operate and I found the thinner clamp jaws (said to be 25% slimmer than previous Fluke clamp meter models) to be a real advantage when working in tight spaces.

58 February 2022 PROFESSIONAL ELECTRICIAN

The display is clear and easy to read and will also indicate to the user where the clamp or loop method is being used. Another handy function is the audio beep that indicates correct PV polarity, making continuity testing easier in low light conditions.

If you're planning to use the 393 FC for extended periods of time, however, I'd recommend you make use of the strap support that comes with the unit.

Overall, I've been really pleased with this clamp meter and am impressed by the accuracy and capability it has offered (see screenshots of the product in use, bottom left and top right).

It only takes a short period of learning to understand how to get maximum benefit from the tool and, thanks to the fact that connectivity to Fluke Connect is also on offer, handwritten note-taking is virtually eliminated.

If your job involves working with high voltage DC equipment, such as the installation and maintenance of industrial and commercial sized solar farms, in conditions that can be cramped/tight, I'd highly recommend you take a look at this clamp meter!

Products IN PRACTICE

Makita provides Max efficiency for Exeter company Balustrade SW has expanded its toolkit with Makita’s XGT 40VMax machines, to ensure heavy-duty applications such as cutting, drilling and grinding can be completed safely and efficiently.

Thanks to its reliable battery performance and product innovation, Makita has been the power tools manufacturer of choice for the Exeter-based company for a number of years.

Its team of technicians, engineers and installers have relied on Makita’s cordless 18V and Twin 18V (36V) LXT machines to construct balustrades, balconies, staircases and handrails across both domestic and commercial buildings. However, due to the heavy-duty nature of the work, the team wanted to expand its existing collection of Makita kit with even more powerful models.

Steve Cupit from Balustrade SW, said: “We've been using Makita’s 18V and Twin 18V LXT machines for around eight years.

They are brilliant products and the ability to swap the LXT batteries between tools is great, as we can quickly and efficiently change between tasks to maximise productivity.”

Makita’s XGT 40VMax machines have been designed for industrial, higher demand applications and offer output that can rival the high power of corded tools, making them the ideal solution for Balustrade SW. As the team regularly work outdoors and at height, the XGT 40VMax cordless machines offer maximum flexibility and additional safety benefits as there is no risk of trips from trailing cables.

The XGT 40VMax machines have also been designed for durability, featuring heavy-duty outer casing and cell holder and shock absorbing housing to protect the battery if dropped. Each XGT battery has an IPX4 rating, which means that it is splash and shower proof, and water ingress is limited which is ideal when working outside in unpredictable weather.

60 February 2022 PROFESSIONAL ELECTRICIAN

Steve continued: “A lot of our work involves stainless-steel and we use the GA013G XGT 40VMax Angle Grinder for cutting the material to size and then the GA005G XGT 40VMax Angle Grinder to grind down the cut edges of the material. These models make work effortless as they offer the same power as 1,100W corded grinders. so we can complete tasks quicker and more efficiently.”

Also in Balustrade SW's armoury is the HR003G XGT 40VMax SDS-Plus Combination Hammer, that the team use for drilling into masonry. The HR003G benefits from a HEPA filter dust collection system to protect users from dust inhalation and antivibration technology to ensure operators can comfortably and safely use the machine over extended periods.

NVC delivers lesson in energy saving Priestley College recently undertook a lighting upgrade project that would not only achieve better environments for learners and staff, but also reduce the cost of energy usage.

The college asked low energy product specialist Extreme Low Energy to design a lighting scheme that would achieve these objectives and Electrical Designer, Matthew McHugh presented the lighting calculations that would be achieved by installing a range of NVC products including: FULTON IP40, 600x600 and side-lit LED panels for UGR<19 compliant lighting schemes in classrooms and hallways; the TEXAS LED economical batten luminaire alternative, which can be used as a direct replacement for outdated fluorescent battens in storerooms; CLEVELAND IK10, IP65 rated industrial luminaires that are suitable for surface and suspended installations in the kitchens; and KANSAS emergency luminaires for the sports hall.

In addition, AZTEC IP65 rated, high-output LED circular, UFO high-bay industrial luminaires; NEBRASKA square IP65 rated, LED emergency bulkheads that have polycarbonate bases, combined diffuser gear trays with quick release restraints and loop-in/loop-out, push release terminals to allow quick and easy

installation; and PORTLAND round IP54 rated decorative LED circular bulkheads that have polycarbonate bases, bezels and micro-prismatic controllers were also utilised.

In total more than 350 NVC light fittings were installed by Extreme Low Energy, which should result in total energy savings of over 54% with a payback of around 14 months. Priestley College will then save approximately £56,000 over five years.

Megaman scores with floodlight installation Oswestry based football club, The New Saints (TNS) FC, recently approached Megaman to help with the specification of a new floodlight system at its home ground, in order to meet the Football Association of Wales’ (FAW) Club licensing requirements.

Having worked with the club before and demonstrated excellent levels of service, Megaman was selected and put forward a floodlight option that could deliver the lux levels required along with high levels of efficiency.

The FAW floodlighting requirements are part of the Club Licensing Infrastructure criteria that has to be met by all clubs competing in the Cymru Premier League, the top tier league in Wales. These requirements state that clubs must install floodlights of 500 lux at the beginning of every other season.

“The new lighting regulations came at a convenient time for us, as we were already looking to update our existing lights to LED,” commented Ian Williams, Chief Operating Officer of The New Saints FC. “Although we received quotes from a variety of lighting specialists, we partnered with Megaman as we had worked with the Projects team before and found them to be very collaborative – offering the right products and experienced support.”

Consequently, the Megaman Projects team helped to create an appropriate specification and recommended a 1,200W outdoor integrated LED floodlight. With a 5000K cool white colour temperature, the same colour temperature as daylight, the floodlights would provide the players and fans with clear visibility, while conforming to the 500 lux FAW requirement.

“Megaman recommended the floodlights that would suitably meet the required FAW requirements which we were then able to quote. The service from the Projects team was second to none,” commented Ian. “I was very impressed with the whole process – from specification to installation.”

62 February 2022 PROFESSIONAL ELECTRICIAN

The Megaman Projects team also recommended Jordan Price from P2 Electrical Services, a regular and trusted installer, to undertake the installation, which involved attaching 12 of the floodlights to each of the stadium’s four corner columns, meaning a total of 48 floodlights were installed.

Jordan said: “We successfully installed all 48 floodlights in time for the start of the football season without any issues. I found Megaman a pleasure to work with. The team stayed in touch at all times to ensure that they were happy with the installation method we used.”

Now installed, the new floodlights provide the required lux levels yet at the same time have cut the wattage of the club’s previous systems in half. This will allow TNS to save on its energy bills going forward.

Cowling Electrical cooks up a Chargestorm Cowling Electrical has recently installed a 3 phase, 11kW wall mounted dual socket CTEK Chargestorm Connected 2 (CC2) at a customer’s head office in Market Deeping, near Peterborough.

Rob Cowling, MD of Cowling Electrical, said: “Our customer is in the process of switching its sales team over to electric vehicles. The CC2 ticked all the boxes for this particular installation, as our customer was looking for a solution that would eventually allow more than one sales person visiting their premises to charge at the same time, even though they only have one EV at the moment.

“The CTEK CC2 is one of the only chargers on the market to have a dual socket on one charger, and it’s a neat way to provide a powerful, dual charging facility. The unit is well made, solid and really easy to install, with simple connections and, as CTEK had met with us beforehand to show us the unit and talk us through

the install, when we got on-site we knew exactly want to expect.”

He added: “The product complemented the first class service we received throughout, and CTEK’s dedicated technical support ensured we could offer a smooth handover for the customer.”

British made range is worth the pipe "In these ever more aware days of global warming and the present focus on reducing carbon footprints, it amazes me why some professional electricians will put up with the lack of quality that comes from some imported conduit pipe bending machines,” says Keith Boldock, MD of Benitnow.

"I say that because I am passionate about our British products. Not only are they top quality and reasonably priced, they don’t come from half way around the world – they’re made in Sheffield, 'The Steel City'.”

Keith adds: “The history we have in this area is second to none. We produced the Hilmor brand before production was moved to the Far East. At that time it opened the floodgates to many companies wanting to make a quick buck and, in my opinion, gave little back in terms of quality.

"At Benditnow you may not know the name so well but what you will get is a quality product at a reasonable price, manufactured in the UK and built to give you years of trouble free-service and the knowledge you don’t have to ship a product in from thousands of miles away.”

He concludes: Take a look at our website and range – most, if not all, of our spares and accessories are compatible with other brands. The products are well manufactured and all our parts are precision machined, giving you greater accuracy and cutting down on waste."

D-Line alternatives to traditional plastic cable cleats and regular conduit saddles, that use pliable fire-rated steel in wrap-and-lock designs, were recently put to time tests where identical runs were set for fixings at 400mm centres in brick substrate, the only variable being the fixings.

D-Line reports how when timings compared cable installations using plastic cleats with wall plugs & screws, for both regular XLPE cable runs and EV-charger cables, the D-Line Adjustable fixings and D-Fix screws took an average 28 seconds per fixing versus 52 seconds for cleats, recording the D-Line solution as 45% faster. Adjustable clips are first-fixable and D-Fix screws need no wall plug.

Compared to regular conduit saddles, for PVC and steel conduit lengths, the D-Line Saddles took an average of 28 seconds per fixing versus 58 seconds, showing D-Line Saddles to save more than the half the installation time for fixings. The main difference is that D-Line Saddles need one screw-fixing only.

Paul Ruddick from D-Line Trade, commented: “If labour is was, hypothetically, £45 hourly, these time-savings alone are worth £0.30 and £0.38 per fixing-type respectively. Then there’s the added benefit of satisfied clients, as customers appreciate the quality of finish.”

Phil Robson, Director of Press Electrical Solutions, added: “The tight wrap & lock design is a great innovation, especially with the screw being hidden, plus there’s peace-of-mind that the D-Line options satisfy the regs too. For all conduits, and armoured cables up to 25mm diameter, we use the D-Line wrap & lock options as a matter of best practice now.”

Products ROUND UP

Put your finger on it with DoorBird Bird Home Automation, a Berlin-based manufacturer of “DoorBird” IP access control devices, is expanding its product portfolio to include door intercoms with an integrated fingerprint sensor.

IP video door stations of the D21x series are now equipped with fingerprint technology from Fingerprint Cards AB, a leading global biometrics company based in Sweden. This enables biometric authentication via fingerprint.

With a DoorBird door station, homeowners and residents can see and speak to their visitors and delivery services on the go via smartphone and unlock the door when needed.

Each door intercom features an HD wide-angle camera, motion sensor and audio system with echo and noise cancellation. Keyless access control via RFID or PIN code is now complemented by a new option: via biometric fingerprint.

The full-frame touch sensor is based on patented technology

by Fingerprint Cards AB and meets high convenience and security standards compared to line-based sensors. The fingerprint reader is fully integrated into the DoorBird software architecture and can be configured remotely at any time.

Via App or web-based dashboard, the user can grant and withdraw access permissions, and also define which event should follow when a certain finger is detected. For example, an internal or external relay can be triggered, or an HTTP(S) command can be carried out. To prevent manipulation attempts, the fingerprint scanner is temporarily locked after ten unauthorised access attempts.

The fingerprint sensor is integrated in DoorBird models with one and two call buttons: D2101FV Fingerprint 50 and D2102FV Fingerprint 50. Each door intercom can store up to 50 fingerprints. Furthermore, customers can create their own customized IP video door stations equipped with a fingerprint sensor and other individual modules via the DoorBird 3D Configurator.

“Thanks to the cooperation with Fingerprints Cards AB, we can now fulfill many of our customers’ requests for high-quality IP access control devices with a fully integrated biometric

Products round up

Draper’s hand tools range boasts the ‘XP’ factor Already known for its popular VDE hand tools range, family run firm Draper Tools has been hard at work over the last two years to build on this offering with several brand new and improved electrician’s essentials.

Introducing XP1000 Draper is proud to unveil the XP1000 range, which is tested to 10,000 V, suitable for use on AC circuits up to 1,000 V and DC circuits up to 1,500 V and fully compliant to EN60900 standards.

Featuring 21 new VDE pliers in tethered and untethered options and 55 VDE screwdrivers, this is a comprehensive series of hand tools designed to see you through a range of jobs throughout your electrical career. XP1000 also includes five must-have sets of pliers and screwdrivers.

Feature-packed tools for the trade Draper's new range has several impressive features. Both the screwdrivers and pliers feature TPE extra-comfort handles and an anti-glare dark paint finish. The slim screwdrivers are excellent for getting to hard-to-reach areas and make a very handy addition to

an electrician’s toolkit. Plus, they feature a dual-layer “insulation warning” blade sheath for safety and peace of mind.

The tethered range in particular is set to be one of the biggest ranges of tethered VDE hand tools on the market. These feature a convenient loop on each tool, allowing for quick and easy attachment to a lanyard and making them well suited for those working at height.

Listening to the experts The XP1000 range was developed with feedback from the industry in mind, and Draper carried out pre-launch testing with a panel of electricians. Over two weeks, they put the range through its paces on various real-life jobs and reported their findings.

The results were encouraging, with over 85% saying they’d recommend XP1000 to others in the trade. Three quarters of the testers said XP1000 was a range they’d buy more of in future, and they all agreed the range was safe to use on-site.

CAUGHT ON

C A M E R A SOCIAL SNAPS!

DAN VEALL: This was found on an EICR in a butcher’s shop. The list of issues goes on and on and on...

CHRIS SMITH: This consumer unit was changed by an approved electrical contractor. They didn’t even remove the old voltage trip…

ASHVANBRO: This is the worst I’ve ever seen – got cowboy written all over it!

ANON: I was asked to put a certificate on a property being let out by an agency.

On top of this, there was a shower switch jammed into a 25mm pattress and a spur in 2.5mm straight out of the cooker control unit. The agency thinks all is fine…!

ERIC: This was taken during a project to change the original kitchen into a utility room and cloakroom. The lighting circuit was originally wired in flat twin, no cpc and later additions in T&E and cpc were borrowed from a neighbouring cable.

MICK HOOPER: EICR time at the house of horrors…!

MIKE BEETLESTONE: A friend recently gave me some logs and embedded in one of them was a plug and socket that was previously connected between the house and the shed. Luckily the power had been disconnected before the chainsaw met the tree!

And one to proud of from JORD_SPARKY… SIMON GERAGHTY: When the customer says he can’t understand why the cooker hood doesn’t work!
