Switched on ‘sparks’ will learn and earn If I was a careers advisor or offering guidance in this area, I'd recommend to any young, aspirational individual to strongly consider a career in one of the trades.

The electrotechnical sector, in particular, is one where the basic skill sets and knowledge acquired can allow individuals and businesses to 'pivot' their offering to suit the current market demand(s), by undertaking the correct training in said area of specialism. No matter which direction the world is shifted towards, the skills of electrical professionals will always be required.

The 2023 Professional Electrician & Installer Magazine Reader Survey (thanks to those 600+ respondents for taking part) has yielded some interesting results, showing that a significant number of electrical businesses and professionals are interested in undertaking proactive training in the following areas: ● EV charge point installation &

maintenance – 48% (of respondents) ● Solar PV installation & maintenance –

47% ● Smart home installation &

maintenance – 44% ● Heat pump installation &

maintenance – 40% ● Fire & security installation & Image References (Adobe Stock): Pg 17 Attracting talent © PsychoShadow Pg 21 CPD sign © BeenaTreena Pg 29 Electrical socket © InnerShadows Pg 43 Solar specialists © Grafstock Pg 50 Online electrician © Kostiantin Pg 54 EV installer © Blue Planet Studios Pg 64 Parcel thief © RightFramePhoto

maintenance – 24% ● General business management &

improvement – 23% ● Commercial lighting installation &

maintenance – 22% ● HVAC installation & maintenance –

20% Plus, other areas of training that individuals are keen to undertake include: harmonic suppression, power quality management, battery storage systems, medical group earthing and small wind & hydro technology.

“Anyone who stops learning is old, whether at twenty or eighty. Anyone who keeps learning stays young.”

Henry Ford Benjamin Franklin famously said: “For the best return on your money, pour your purse into your head.”

Its encouraging to see that a larger portion of the electrical industry workforce is beginning to appreciate that wisdom and understands that the opportunities exist – now and in the future – to earn a more-than-decent living from enhancing the skill sets they’ve already acquired.

This sector, in my experience, is one that has an appreciation for the need for, and value of, taking part in events and undertaking learning and training exercises.

You only need to take a look at the number of electricians that make their way to our ELEX shows, and a significant number of other events throughout the year, all in the name of maintaining and improving upon their existing skills and knowledge.

To help you with some ideas and routes for training in 2024, we’ve got a dedicated ‘Training’ section featured in this issue (starts on page 54), where you’ll be able to learn more about the latest courses and dates.

We’ve also got an exclusive article with Hager’s Technical Training Managers to learn more about the launch of a new online training platform that you may well make use of in 2024 (pages 18 & 19).

Have a good month and enjoy the issue,

Danny McBean wins SkillELECTRIC gold 21-year old Danny McBean has been crowned 2023 SkillELECTRIC champion after excelling in an intensive UK Final competition over three days at Oldham College.

Taking second place and a silver medal was Ben Gillin from Lloyd Morris Electrical and JTL. Third place and a bronze medal went to Conor McDonnell of Nesbitt Electrical and Southern Regional College in Northern Ireland.

Danny, a SECTT apprentice with UHI Moray and employed by Grants (Dufftown), took top marks over his fellow finalists in a complicated electrical installation task comprising four circuits, SWA and FP cable, lights, sockets, conduit, trunking and a smart module.

The task had to be completed within a strict timeframe and was marked against tough criteria including wiring and connection skills, inspection and testing and measuring and marking out, which had to be accurate within + / - 2mm.

In a first for this year, competitors also

completed a solar PV-related task to reflect the fact that the core competence of a qualified electrician is the foundation from which to upskill and train in solar installation.

All finalists that took part received a range of fantastic prizes and, as the winner, Danny also received a

multi-function tester from Megger, an enhanced iPad Pro from the NICEIC and a tool set from Oldham College. Danny, Ben and Conor also received a VDE Plier Set from C.K Tools.

Speaking after his win, Danny said: “I’m absolutely over the moon; I still don’t believe it, when they read out the name I was just frozen for a second! Well done to all the other competitors; all the judges were saying it was really close and one of the most competitive years. I just want to say thank you to my dad (who’s my lecturer) for training me and always looking at ways to work harder and more efficiently, and to my employer for giving me the time off to practice and take part.”

This year’s SkillELECTRIC competition opens in February.

Ryan aims to be lord of the Dance An electrical industry professional is taking on the Fan Dance challenge race later this year in an effort to raise funds and awareness for a mental health campaign run by SignPosted Cymru.

Ryan Dempsey, CEO of TCW, has agreed to take on the gruelling task which takes place in July. The Fan Dance is a 24km SAS Selection test march staged over Pen y Fan, the highest mountain in the Brecon Beacons. The infamous march is the world’s oldest Special Forces test and is used as the first major indicator of whether a candidate has the physical and mental aptitude to complete the legendary Selection course.

Explaining more about his reasons for undertaking the challenge, Ryan said: “A few years ago I was asked to take part in a mental health awareness campaign which was created by Darren Thomas at SignPosted Cymru.

10 January 2024

“The journey I went on was an eye opener, and since then I’ve learned so much about the ‘black hole’ that a lot of individuals are currently pretending not to be in. The work Darren does is admirable, so I just wanted to be able to help in some small way.”

As part of the challenge, Ryan has set up a JustGiving page and would be hugely grateful for any donations or shares that readers are able to provide.

COMMENT

“OPEN YOUR HEARTS AND MINDS TO CHANGE”

A

war for talent sounds like a dramatic statement intended to grab the eyes of the reader. Let me assure you it’s not. The simple fact is that fewer school leavers are actively seeking to study building services and graduate engineers are not currently leaving university and falling over themselves to join this industry, as they once were.

Some of the reasons could be seen as being out of our control. Industries such as software development, oil and gas, aerospace and defence are offering greater benefits, remuneration packages and career opportunities. For example, a Junior Developer entering a public sector role on graduation can expect to earn £75-100k per annum with excellent benefits and job security.

So, what can we do?

I’m part of the ‘internet/outernet generation’. We were the last kids to play outside until the street lights came on and the first to use the modern internet. I believe this allows us to provide a unique perspective on this situation. So here are my thoughts, musings, opinions and suggestions: Digitise. Digitise. Digitise.

You may not require to or want to digitise your business, and that’s OK. But in terms of attracting young people to our industry, it’s an absolute MUST. The current generation of young engineers knows no different and to step into a role in an ‘analogue’ business would feel a bit like stepping back in time. If we do manage to attract talent it

Be respectful and responsible We have a whole generation who have a greater sense of social and environmental responsibility and quite frankly, feel ignored most of the time. We may not be able to offer ‘Developer’ big bucks but for a lot of young talent it’s not all about this. To be heard, understood, and contribute to making a difference in the world is more important. We need to listen to them.

opinion of this sparky-turned-engineer-turned-CEO that we are. Minor changes to our attitudes, culture and business practices could turn this fight around. All we have to do is open our minds and hearts to change.

Let’s fight together and win.

Upskilling is overtaking promotion It’s not 1985 anymore. ‘Wolf of Wall Street’ culture is stone dead and will not incentivise this generation. For some it may be hard to believe, but offers of a solid career path and an opportunity to contribute and upskill tends to trump a bonus cheque or a new BMW. Treat young talent as you would mature talent The days of coming in as the tea boy and working your way up are over.

We’re recruiting for responsible roles so why wouldn’t we give responsibility and rewards quickly?

Young engineers know their worth these days and (some of) the older generation could benefit from catching up to that fact!

So, in this battle to attract talent in our industry, are we on the losing side? It is the humble

COVER STORY

ASK THE EXPERTS

E

ngaging in regular training is an essential aspect of the development of careers, conducting high quality work, and enhancing business growth within the electrical industry.

Hager is leading the way – determined to provide insightful information, advice and support from industry experts, and proud to offer a wide range of training programmes, both online and in-person.

The brand’s Technical Training Managers, Paul Chaffers and Paul Collins, are both figureheads within the industry, boasting over 70 years of collective experience.

Between them they develop and deliver various training programmes, present seminars and webinars, and support Further Education colleges with wiring regulations and Inspection & Testing courses.

Thanks to their extensive knowledge and unwavering commitment to the industry, they’re also both BEAMA representatives. They’re passionate about striving for – and maintaining – a safe, innovative and compliant industry.

Here we chat to them both about why a keen focus on training is vital for business, and they share their motivations behind their latest educational offering: Hager Academy Online.

Paul Chaffers, you’re well-known to the industry but relatively new to your role with Hager – how have you been settling in and what have you been tasked with doing?

Q

It’s been great, I’ve very much enjoyed becoming part of the team at Hager – they’ve all made me feel very welcome.

Although it’s a new role for me in-house, I’ve actually been working alongside Paul Collins for over a decade – delivering seminars at major trade events, catching up at BEAMA conferences, and taking part in expert panels. Now, both part of the Hager technical team, we’re able to more easily collaborate on projects, utilising our combined experience to provide value for industry professionals.

18 January 2024

PE puts the questions to Hager’s Technical Training Managers, Paul Chaffers and Paul Collins, as we discuss all things training.

“... the launch of Hager Academy Online is a natural evolution...”

So far, my main focus has been on writing new training material for our newly-launched Hager Academy Online – a free learning platform for Hager product training and CPD-accredited courses.

Plus, we’ve also been revamping the in-person training held at our Telford headquarters, which has seen us create a whole host of new content in line with the latest regulations.

Why is it important for electrical professionals to have in-depth training and expertise to call on when it comes to their day-to-day work and personal development?

Q

means that there’s more information to be shared, discussed and understood. These topics often require extra care and attention when designing and selecting the correct choice of circuit protection.

So, as experts in this field, we help to bridge the gap between what’s covered in standard training courses and the finer details of the modern manufacturing world. Armed with this valuable information, professionals can stay ahead of the game and ensure they continually offer safe and compliant installations.

Hager has recently announced the launch of an online learning platform – tell us more about the inspiration behind this and how it works.

Q

CHAFFERS: Simply put, the regulations are constantly changing and so regular training is essential to ensure you remain up-to-date, safe and compliant.

COLLINS: Yes, the launch of Hager Academy Online is really exciting. It’s a natural extension and evolution of the face-to-face training that we already offer.

Providing this knowledge on an online platform means it’s accessible from anywhere, at any time, and in different formats to suit every learner.

COLLINS: Also, the innovation of renewable energy and EV charging

CHAFFERS: Essentially, there’s two aspects to the training. Firstly, we offer

PROFESSIONAL ELECTRICIAN

018_PE_JAN24_Layout 1 01/12/2023 08:27 Page 19

product-specific support for customers wanting to better understand device functionality and product codes – this is mainly designed for wholesalers.

For electricians and electrical designers, there’s a range of technical courses, curated to cover different areas of the wiring regulations and provide technical solutions. These are all CPD-accredited and upon successful completion an industry-recognised certificate is issued.

You’ve mentioned that this is an evolution from your in-person training, can you tell us more about the other types of training options?

Q

CHAFFERS: For those who want to sit a formal qualification, we’re proud to partner with some of the best training providers in the UK, which allow us to host these courses at our Hager Academy. Plus, we also have several in-person CPD training courses available too.

The training sessions are typically conducted over the course of a week.

Throughout this time, learners receive theory sessions and practical demonstrations from industry experts, as well as a look behind-the-scenes. These include gaining extra tips, tools and tactics from multiple members of the Hager team, a full tour of our factory, and a visit to the laboratory.

Q

learning from other experts is immensely helpful – and also provides alternative perspectives and opinions.

COLLINS: Renewable energy and EV charging are at the forefront of the industry right now – with battery storage and solar PV courses our most in-demand currently. Rightly so, installers are seeking advice and guidance into the latest advancements and the newest products within this arena.

COLLINS: Authoring articles, writing webinars and participating in panel discussions requires extensive research and learning. Due to this, huge parts of our roles include delving into and dissecting the latest trends, products and legislation. Also, Hager boasts a wealth of knowledge through its technical experts worldwide who are always on hand to provide support and insights.

What areas of training and education have you noticed are proving most popular when it comes to interest from electrical professionals?

CHAFFERS: It’s also exciting to be a part of this movement. It’s a pleasure to work alongside our national community of electricians, contractors and installers, together driving forward these innovative projects and products within the industry.

The training sessions allow for great conversations, exciting collaborations, and a chance to stay ahead of the game when it comes to an exciting new world.

We regularly see you – and the Hager team – at trade show events up and down the country. What’s the value of delivering training and being present at those types of events?

Q

Q

COLLINS: We enjoy connecting and collaborating with our customers face-to-face. Not only do such events allow us to demonstrate our latest products or share the latest technical solutions, but they also gift us the opportunity to gain feedback from the industry. Being able to have these open, honest and candid conversations ensures we’re servicing our customers exactly as they need.

CHAFFERS: Being part of technical committees, such as BEAMA, involves lots of reading which keeps me notified of any changes. Also, meeting, engaging and

Q

How do you both keep on top of the changes that are going on in the industry so that you’re able to confidently and accurately deliver material to others?

How does Hager plan to expand and improve its training offering this year? Will there be new courses?

CHAFFERS: Our in-person and online training is constantly evolving.

Regulations regularly change meaning we have to alter sessions, new products are launched resulting in additional courses being created, and the industry is constantly advancing, so there’s a huge scope for growth.

COLLINS: To begin with, we’re offering mainly residential subjects, but throughout the course of the year, we’re looking to expand this to cover commercial and industrial topics too. Watch this space…

THE

CODEBREAKERS ERIC WILLIAMS: I WAS ASKED BY A CUSTOMER TO REPLACE A BROKEN SOCKET THAT WASN’T WORKING AND TRACED THE WIRING BACK TO A CIRCUIT BREAKER IN AN OFF-PEAK CONSUMER UNIT. ON CHECKING THE SOCKET AFTER REPLACEMENT, WITH THE OFF PEAK NOW ENERGISED, IT WAS FOUND TO HAVE REVERSED POLARITY. ON OPENING THE OFF-PEAK CONSUMER UNIT (PICTURED) THAT WAS INSTALLED APPROX. 40 YEARS AGO (SUPPLYING FIVE STORAGE HEATERS), I FOUND THE METER TAILS REVERSED, WITH EACH OF THE TAILS PASSING THROUGH A DIFFERENT OPENING IN THE METAL ENCLOSURE, NEITHER OF WHICH HAD GROMMETS! You can never assume that an older installation was installed, commissioned, and tested correctly. We often find that older installations can harbour some poor and dangerous practices. As we work through the findings, the lack of grommets is no more than perhaps a C3 unless there is mechanical and thermal damage. They’ve not been there for 40 years, without either, but that’s not to say every installation would be like this. Eddy currents only really start to take effect on equipment subjected to continual high current loads.

In domestic single and polyphase installations, up to 100 A, it’s very unlikely there will be a problem. We generally see Eddy current overheating and damage on polyphase commercial and industrial installations, dealing with larger loads. In this case, the installation is only 60 A, and storage heaters are only energised for a cyclic period so, unless there are signs of thermal damage, no more than a C3.

There also appear to be some cable entry points not being used, which are likely to represent an IP issue. One certainly

Older storage heaters generally don’t have complex electronic controllers that require correct polarity and, subsequently, don’t have reversed polarity diode protection, which stops the equipment from operating and forces maintenance to be carried out.

Also, as the polarity is reversed, we now have switches in neutral conductors, which isn’t allowed, and no individual circuit isolation, as the MCBs are only isolating the neutral. Not noticing the reversal, a maintenance engineer would think they have isolated a circuit to carry out some maintenance, only to find that the neutral circuit conductors are still live.

The only way to isolate any of the installation storage heaters would be to isolate them at the CU main isolator.

KYLE GAMBLE: WE WERE CALLED TO A JOB WHERE A CLIENT HAD A KITCHEN REFURBISHED AND WAS GETTING SHOCKS FROM THE DISHWASHER! EVERY SINGLE WIRING ACCESSORY WAS SIMILAR TO THE PHOTOS. There were so many photos from Kyle’s call-out, so I chose those that I found would give the best impression of the many faults he’d found.

Firstly, the left and centre photos show the connections for recessed downlights.

In both photos, we can clearly see that the cpc has been cropped and not continuous; this means that a cpc has not been taken to every point and accessory in the circuit. This alone is an unsatisfactory finding, but the centre photo shows that the manufacturer had supplied a terminal to connect the cpc, which would have ensured the integrity of the cpc throughout the circuit.

The outer sheath of the twin and earth cable on both light fittings has been

removed, leaving single insulation exposed and not taken into the enclosure – another unsatisfactory finding.

It looks as if the line conductor terminals have been twisted together, leaving only one of the conductors in a termination, relying on the twisting to give mechanical joint stability, so again not satisfactory.

In the third photo, which I’m assuming is a fused connection unit (FCU) (as the photo isn’t too clear), we can again see the cpc is cut and not continuous; therefore, not taken to each accessory and point in the circuit. With the general lack of electrical understanding, by removing the cpcs, which are fundamental to safety, it’s more than possible that the dishwasher has a current present on its housing or casing.

The current present could be innocent leakage current, which is classed as functional and therefore normal, but without a cpc to allow this to have a pathway back to the MET, anyone in contact with it could become the pathway. It is most likely that the shocks were perceived shocks. Regardless, perceived shocks can instill a significant amount of fear into those receiving them and highlight that the installation user could receive a fatal electric shock in the event of a fault.

A genuinely horrific installation, cobbled together by someone with no understanding, skills, or conscience.

METAL CONSUMER UNITS IN INSTALLATIONS FORMING PART OF A TT EARTHING SYSTEM This article from the experts at NICEIC aims to provide guidance for contractors when required to install a consumer unit and/or similar switchgear manufactured from a noncombustible material meeting the requirements of regulation 421.1.201, in a domestic installation forming part of a TT system earthing arrangement.

W

here an installation forms part of a TT system earthing arrangement, irrespective of the type of material the consumer unit is manufactured from, regulation 411.5.2 typically requires the installation of one or more RCDs as a protective measure for fault protection.

Any RCD providing fault protection shall be erected at the origin of the installation that is to be protected (531.3.5.3.1). In an installation with multiple origins, this requirement shall apply to each origin.

Most TT installations are likely to also contain multiple RCDs providing additional protection, or possibly fault protection, either protecting groups of circuits and/or individual circuits. Where this is the case these protective devices shall be selected and erected as to limit the risk from unwanted tripping (531.3.2).

Similarly, where multiple devices are installed and there is a need to minimise the inconvenience of unwanted tripping during a fault, the requirements for selectivity will need to be considered (536.4.1.4).

Installation of a metallic consumer unit The installation of a metallic consumer unit complying with BS EN 61439-3 is most likely to be the preferred option for

Fig 1. Effect of a fault to earth between incoming tails and the metal case of a consumer unit

achieving compliance with the non-combustibility requirements of regulation 421.1.201. However, care must be applied to the installation method adopted where a metal (Class I) consumer unit is installed in an installation forming part of a TT system.

An earth fault occurring between the line conductor of the meter tails and the metallic enclosure, as shown in Fig 1, will not be detected by the RCD installed in the consumer unit. The metallic casing of the consumer unit and subsequently all other conductive parts connected to the main earthing terminal (MET) of the installation will rise to a potential approaching close to the supply voltage (230 V to Earth), creating a potential shock risk.

Under such circumstances, due to the

high external earth fault loop impedance (Ze) typically associated with a TT system, which can often exceed 100 Ω, the earth fault current is unlikely to reach the level required to operate the service fuse, and even if it does the operating time is unlikely to be within the 1 s disconnection time required by regulation 411.3.2.4.

For example, if the maximum earth fault loop impedance is taken as 100 Ω also taking into account the seasonal changes of ground resistance for a single phase supply, and minimum voltage factor (C min) of 0.95, the earth fault current that will flow under such fault conditions can be calculated as follows: 𝐼f c = 230 x 0.95 = 2.2 𝐴 100

PROFESSIONAL ELECTRICIAN January 2024 25

THE CPD ZONE

Clearly, this level of fault current is insufficient to operate the distributors’ overcurrent protective device and therefore, unless a low value of (Zs) can be assured and maintained while meeting the requirements of regulation 411.5.3 for fault protection, such a fault will remain uninterrupted. For this reason it is preferred that fault protection for an installation forming part of a TT system is provided by an appropriately rated RCD (411.5.2).

In addition, the selection of an appropriate RCD for a particular installation shall meet the requirements of regulation 531.3.5.3.2. Such that, the rated residual operating current (𝐼Δ 𝑛) of the chosen RCD shall not exceed the (𝐼Δ 𝑛) corresponding to the maximum value of earth resistance (Ra), including that of the earth electrode and protective conductor connecting all exposed-conductive-parts.

In the aforementioned example the maximum earth fault loop impedance is 100 Ω and therefore, the maximum rated residual operating current of the chosen RCD shall not be greater than 500 mA, given in Table 53.1 of BS 7671 and partially reproduced in Table 1.

Meter tails It may not be possible to eliminate all risk associated with protecting meter tails from a fault to earth typically, between the origin and the RCD protective device within the consumer unit. However, by adopting longstanding industry practices applied by many electrical contractors, such as those listed below, the risk can be mitigated sufficiently: ● use of thermoplastic or thermosetting

insulated and sheathed cables for the meter tails (531.3.5.3.2.201), and ● positioning of the consumer unit in close proximity to the energy meter, reducing the length of the meter tails to a minimum to mitigate the risk of damage, ● fitting an insulated cable gland, bush or similar to protect the cables from abrasion as the meter tails enter the metallic consumer unit and/or protective enclosure, as shown in Fig 2.

Table 1. Maximum value of earth resistance (Ra) in relation to rated residual current of the RCD

Additionally, in order to avoid the effects from induced eddy currents in the metallic enclosure and any consequent heating effects, all associated meter tails should enter the consumer unit through the same entry point (one cable entry knock-out hole).

Degree of protection The requirement of regulation 421.1.201 is intended to ensure that any source of ignition, such as arcing caused by a loose termination occurring within the consumer unit and/or switchgear assembly, is prevented from igniting the enclosure while reducing the risk of any fire from spreading externally.

It is for this reason that the entry points of all cables, including that of the meter tails, into the metallic consumer unit should not, so far as reasonably practicable, reduce the fire integrity provided by such equipment. Cable entries, such as those often used for back entry into the consumer unit must be provided with suitable sealing methods and may include intumescent gaskets, grommets and/or fire sealants to maintain the degree of fire integrity.

However, it is generally accepted that the requirements of regulation 416.2.1 and 416.2.2 which are intended to prevent contact with live parts also help to maintain the fire integrity of the consumer unit. A degree of protection of at least IPXXB or IP2X should be maintained for the top surface of the consumer unit and a degree of protection of at least IPXXD

26 January 2024 PROFESSIONAL ELECTRICIAN

Fig 2. Insulated bushes for entries to Class I enclosures

or IP4X maintained for all other surfaces of the enclosure.

Where the installation of a consumer unit is to take place on or in a combustible prefabricated wall, additional precautions must be applied to prevent the ignition of surrounding materials.

Equipment having a greater degree of protection will be required which must be maintained of at least IP3X (422.4.1).

Using appropriate types of equipment conforming to the relevant standards for temperature rise will meet this requirement (422.4.201).

Where the installed equipment, such as an all-insulated construction consumer unit, fails to meet the requirement of regulation 422.4.201 further preventative measures shall be applied to prevent the spread of fire. This may include the use of a secondary enclosure manufactured from a non-combustible material of suitable thickness, for the containment of the consumer unit (422.4.202).

Summary There is a greater risk associated with the installation of a metallic consumer unit in an installation forming part of a TT system earthing arrangement. It is for this reason that consideration must always be given to the location of the consumer unit and length of meter tails in relation to the energy meter.

Appropriate installation methods and practices that have been applied by electrical contractors for many years continue to minimise the risk of damage to the meter tails and subsequent earth faults.

It must be recognised the need to maintain the degree of ingress protection and the fire integrity of the consumer unit in relation to the type of installation method.

Keith Willcock, Product Manager for Siemens Alpha Circuit Protection Products, reviews the implications for designers and installers of electrical installations from the latest requirements for additional protection for socket outlets in BS 7671, including Amendment 2.

ARE MCBS BECOMING OBSOLETE?

Regulation 411.3.3 Within Chapter 41 (protection against electric shock) Regulation 411.3.3 now tells us: ‘.. in AC systems additional protection, by use of a 30mA residual current device, must be provided for socket outlets (not rated higher than 32 A) in locations where those socket outlets are likley to be used by persons of capabilty BA1, BA2 & BA3. There are no exceptions to this requirement.’

Previously this regulation did not overtly consider user capability. The regulation concerned itself with the equipment type i.e. socket outlets. Now the person using the socket outlets is the principal consideration for designers and installers.

What are BA1, BA2 & BA3?

The terms BA1, BA2 & BA3 are explained in BS 7671 Appendix 5 of the Wiring Regulations, which includes a list of external influences, and, in table B, under the sub heading of ‘Utilization’ BA, refers to the capability of persons. BA1 is described as an ordinary person (a person who is neither a skilled person nor an instructed person), BA2 as children, and BA3 as disabled persons.

Which locations are included?

Regulation 411.3.3 does not give a list of typical locations, so designers and

installers have to determine for themselves which locations include socket outlets that are liable to be used by ordinary persons, children or disabled persons. Typical obvious locations will include schools, universities, offices, factories, hospitals, nurseries, care homes, hotels, and indoor/outdoor locations. Actually, its hard to exclude any locations, the requirement really means all workplaces, all leisure facilities, and all living accommodation. No exceptions permitted.

What is a socket outlet?

People probably imagine a common BS 1363, 13 A, three pin socket outlet when they read Regulation 411.3.3, but the regulation isn’t limited to 13 A sockets – it includes all types of socket outlets up to a maximum rating of 32 A. The regulations state that a socket outlet is a device, provided with contacts, which is intended to be installed with the fixed wiring, and intended to receive a plug.

Taking account of all the types of premises with the relevant locations covered by this regulation there will be a wide variety of socket outlets that must have additional protection by a 30mA residual current device, including 2, 5, 13, 15, 16, 20 and 32 A round pin, square pin, fused or unfused indoor or outdoor sockets.

What is the solution?

The simplest compliant solution is to use an individual Type A 30mA RCBO on each circuit that supplies power to any socket outlet. This will meet the requirement for additional protection, avoid unwanted tripping, and maintain power continuity on healthy circuits.

Type A RCBOs are suitable for circuits with equipment incorporating electronic components that may produce DC currents; such equipment is commonplace in modern installations.

Type A RCBOs are designed to trip on alternating sinusoidal residual current and on residual pulsating direct current.

MCBs won’t meet the requirements of BS 7671 for additional protection and shouldn’t be utilised for the circuits that supply socket outlets which will be used by ordinary persons, children or disabled persons.

Footnote: Designers should not group several socket circuits on a single 30mA residual current device as this can actually cause unwanted/nuisance power outages to healthy circuits that share an RCD with a faulty circuit, and is very unlikely to comply with the wider requirements of BS 7671: Chapters 13 & 31, Regulations 531.3.2 etc

EV QUESTION TIME: PART 2

I

nstallers at our UK training sessions will ask a lot of questions when they’re learning how to best install EV charge points. But, there are certain topics that will crop up time and again at training events up and down the country.

In my experience, installers are keen to find out all about EV charging, how the charging units work and the steps to effective installations. They’re an inquisitive lot and ask some very good questions at each session.

Last month I covered questions relating to EV charge point RCD protection, IK impact ratings and AC & DC chargers. This month I’ll broach two more questions:

Which type of load management is needed?

Introduction of any EVSE equipment to a property will inevitably add additional strain onto the supply network and the local installation itself. It is important to understand what the maximum demand of the property is prior to installation of charging points. It is also important to remember that diversity cannot be applied to EVSE since it will operate at

Q

30 January 2024

In this follow up to last month’s article, Viktors Nikolajevs, CTEK’s Skillbase Manager in the UK, answers more of the key questions that installers are commonly raising around EV charge point installations. the rated level continuously, unless limited through configuration or instructed otherwise by the vehicle.

BS 7671:2018+A2:2022 Section 722.311.201 states that load curtailment, including reduction or disconnection, either automatically or manually, can be taken into consideration when determining the maximum demand of the installation. In many situations manual load reduction (through configuration) can impede the user experience when charging vehicles, so automatic approaches through load management equipment or software would be more appropriate.

PROFESSIONAL ELECTRICIAN

There are two variations of load management solutions available – static and dynamic. Dynamic load management typically includes installation of additional meters and/or current transformers to the incoming supply to measure the overall power consumption of the property. The measured values would then be assessed by the EVSE or the load management controller, allowing the EVSE to use the remainder of the supply to charge the EV. Furthermore, DNOs may require dynamic load management to be installed if the Maximum Demand thresholds, explained in Energy Network Association (ENA) Electric Vehicle Charge Point and Heat Pump Connections Process, are reached or if local transformers have limited capacity.

Static load management can be used in installations where the actual power consumption of the property is known and is relatively stable. The power consumption of the property does not need to be measured continuously, so there is no need for additional meters or CTs, and there is a dedicated amount of power capacity dedicated only for vehicle charging. The load management is then

030_PE_JAN24_Layout 1 01/12/2023 08:58 Page 31

carried out against this dedicated power capacity. Such solutions can be well suited for small office buildings with a low number of charging points.

Installers and designers have to consider whether online or offline load management is more appropriate. When using online (cloud-based) solutions, consider how the charging points would behave in case of internet access loss.

This behaviour varies from manufacturer to manufacturer, and in some cases can either send the chargers to minimum output mode, maximum output mode or disable them completely.

Offline solutions operate locally. Should connection to the internet be lost, the load management will continue to function as pre-programmed by the installer.

What is the OCPP and why do I need to know about it?

Open Charge Point Protocol (OCPP) is an open-source communication protocol used to make EV networks open and accessible. It can be thought of as a common language, which allows different hardware manufacturers and software developers to produce cross-compatible solutions, even if they have never worked together.

Q

OCPP-compliant hardware providers allow the customers to decide how they want to operate their charging points, which software they use or which EV charge point tracking Apps can interact with the stations. Additionally, should a manufacturer of OCPP-compliant hardware or the back-end provider go out of business, the owner will have an easy way of switching the back-end, rather than completely losing access to their charging points.

In simple terms, when manufacturers implement OCPP support, the EV charge point owner/operator can decide what software platform they want to use to manage their charging network and set up methods of payments. The EV charge point operator can then manage charging stations from different manufacturers in the same software.

Another aspect of often overlooked benefits of OCPP is hardware longevity. If the manufacturer of EV charging stations without OCPP support goes out of business or stops supporting those stations on their platform, then the stations would lose all of their smart functionality or become completely disabled. Having OCPP allows switching the back-end software to prolong the

longevity of hardware should such unforeseen circumstances occur.

Currently, there are three versions of OCPP available – 1.5, 1.6 and 2.0.1. The most commonly used version now is 1.6.

Both the charging point and the back-end solution should be able to use the same version of OCPP for successful connection.

Join the training gang The appetite for EV installation training is growing all the time as more installers want to expand their knowledge of what is a huge growth market.

A City & Guilds survey of installers found 45% of employers only recruit electricians who are already qualified or competent to install EV chargers. So, here at CTEK we’re committed to providing our Skillbase training to many more installers.

Installers are invited to free online CTEK training events to learn more about installing EV charging infrastructure. The sessions will run at 9am and 1pm.

IT’S NOT ALL TWIN AND SLING The technical experts at NAPIT look at different installation methods and the mechanical protection requirements for each.

Installation or wiring methods?

Whenever we speak to contractors or they ask our advice on an installation or wiring type, there is often some confusion over the different installation methods and how they can be used.

Let’s be clear, wiring methods are different ways of saying installation methods, so they are generally taken as being the same principle.

What’s a wiring system?

These differ slightly from installation methods and refer to a cable or system containing both basic and mechanical protection when installed and commissioned correctly.

PVC/PVC flat twin and earth cables are classed as a wiring system as they possess all of these properties and also include a cpc, as do SWA, MICC, soft skin

fire cables (FP200 and similar) and many other similar cable types.

The systems we use to support these cables are referred to as containment because they contain the cable wiring system. A containment system or method

is not a wiring system, and in most cases, it can be used for, or with, many different wiring systems.

One such example of a containment system is the cable basket, as shown in Fig 1, where the open metal frame design offers less surface area so increases air circulation and prevents both heat and dust build-up.

Another cable containment system is the cable tray, as displayed in Fig 2, which are commonly used to support a multitude of light-weight cables. In the same way, we may choose to use cable clips or cleats.

These can be used for many differing wiring systems; the clips or cleats themselves vary by design, but the principle behind their use is basically the same.

For heavy duty and high volume cables, cable ladders are typically used as a containment system, as shown in Fig 3.

PROFESSIONAL ELECTRICIAN January 2024 33

033_PE_JAN24_Layout 1 01/12/2023 09:00 Page 34

THE CPD ZONE

When we use singles, 6491X and similar, these are only half of the system.

As 6491X cable only possesses basic insulation and no mechanical protection, we have to install them inside suitable mechanical protection. We can’t call 6491X cable a system, unless we also refer to its mechanical protection part at the same time.

There are two basic principles for mechanical protection of 6491X single cables, which are conduit and trunking.

These again are split into two types of material construction, leading to four distinct types in total.

Fig 4 shows the two material types for conduit protection, metal and plastic.

For 6491X to be called a system, it needs to be referenced with one of these four mechanical protection parts. These two mechanical protection parts of a system, conduit or trunking, although they serve the same purpose, have very different properties and skill sets needed to install them.

Fig 5 and Fig 6 indicate the two material types of trunking, metal and plastic. Indeed, the different materials used to construct each of them also have very different installation techniques and skill set requirements.

We generally wouldn’t use a separate containment for 6491X/conduit systems, as the system itself is the containment. A conduit system, whether metallic or plastic, will use saddles to secure them, but these are considered to be integral to the wiring system and not optional. We wouldn’t lay conduit or trunking onto a cable tray or basket, for example, as this is not a proper use of either piece of equipment.

34 January 2024

What about the cpc?

With metallic conduit and trunking, the structure itself takes on the role of the cpc, so only the line and neutral of the circuit are carried internally, with a connection made at the accessory to either the conduit or the trunking.

Plastic conduit and trunking are obviously non-conductive, so the cpc for each circuit must be taken inside with the line and neutral conductors to each accessory served.

Which one do I use?

A designer can use whichever they choose to, but will generally be driven by the following: ● Client needs or requirements ● Usage ● External influences ● Durability ● Accessibility for maintenance, repairs

or alterations.

Flexible metallic conduit is often utilised for connections to equipment, although there has been an increase in its use for connecting solid metallic conduit between expansion joints within buildings and similar.

One thing to remember is that flexible metallic conduits are unsuitable for use as a cpc; therefore, any links between fixed metallic conduits would require earthing links to ensure the earth continuity of the containment system.

PROFESSIONAL ELECTRICIAN

Whichever method is used, the installer must possess the correct skills needed.

Complex wiring systems need high levels of competence and experience to ensure compliance with BS 7671.

Both plastic conduit and trunking arguably require less complex equipment and training to construct; however, they are not easy to install correctly. Metal conduits generally require specialist equipment to install, and metallic conduits will likely involve powered cutters or tooling.

When dealing with containment, the same applies, although generally speaking, power tools will need to be used to install most cable tray and ladder products.

Can you mix and match?

Mixed systems are often seen and indeed necessary, for example, when going from a trunking system to a conduit system to disseminate final circuits for point of use, etc.

We also see cable systems inside trunking to reduce the need for

033_PE_JAN24_Layout 1 01/12/2023 09:01 Page 35

unnecessary containment, where the circuits wired in a cable system are limited. It’s usual to see the odd SWA, MICC or other such cables in trunking alongside 6491X singles, especially where modifications and alterations to an installation have been made.

Things can get trickier with conduits, as the friction from pulling a sheathed cable system through them can damage them and any other 6491X singles in the same conduit.

In both cases, the designer needs to take into account any thermal constraints, as a wiring system may have its current capacity impaired by the enclosed effects of being encased in a conduit or trunking.

Likewise, the thermal constraints of the 6491X conductors may be affected where a sheathed wiring system is introduced to

the same conduit or trunking.

We can’t mix and match 6491X or similar singles by placing them on either a cable tray or ladder, as they would not have mechanical protection. So, from a mix-and-match perspective, wiring systems can use trunking and conduit as a containment method if thermal constraints allow, but singles must be in either conduit or trunking.

Is twin and earth only for domestic?

Often seen as a domestic-only wiring system, PVC/PVC flat twin and earth, is actually far from it. Twin and earth and similar variations are wiring systems in their own right, and can be used in commercial and industrial installations, where the designer sees fit.

The only problem you will find is that

they are less flexible, given their solid conductors, below 4 mm2. Other than that, they can be used anywhere a similarly specified cable wiring system can be used, providing they meet the requirements for low smoke and fumes.

Conclusion We have several options for the type of installation method we use; each has its merits, drawbacks and varying levels of difficulty of installation. This is beneficial as it gives the designer options to choose the best possible solution.

SURGE PROTECTIVE DEVICES Hager’s Technical Training Manager, Paul Chaffers, discusses the importance of providing installations with surge protective devices (SPDs) and looks at requirements and considerations of BS 7671:2018+A2:2022.

i

n our everyday life, we’re surrounded by electrical equipment which may contain sensitive electronic components. Such products are vulnerable to transient overvoltages and can have their lifespan significantly reduced through degradation and damage.

Understanding overvoltage protection can be very complex, but from an electrician’s point of view, the Wiring Regulations are now much simpler than previous editions that required complex thunderstorm risk assessments.

Voltage disturbances in the form of overvoltage can originate from outside of an installation or from within the installation itself. In fact, about 35% of all transients come from outside the facility with the remaining 65% generated inside our homes and facilities – see Table 1 (pictured, right) for examples of where such transients may originate from.

General requirements Understanding how to use BS 7671 correctly is the key to success.

Unfortunately, too often installers look at an isolated “Section” or “Part” of the Regs, without considering the general requirements that must always be applied. An example of this would be only looking at Section 443 (Protection against transient overvoltages of atmospheric origin or due to switching) and not considering the Fundamental Principles.

BS 7671 Chapter 13 deals with Fundamental Principles, with Regulation 131.1 providing a number of conditions in electrical installations that may present a risk of injury. Indent (iv) of Regulation 131.1 includes voltage disturbances (undervoltage and overvoltage) meaning

that where there is a threat of this occurring, protection is required.

Furthermore, Regulation 131.6.2 requires persons and livestock shall be protected against injury, and property shall be protected against damage as a consequence of overvoltages.

“Voltage disturbances in the form of overvoltage can originate from outside of an installation itself.”

Definitions Part 2 of BS 7671 does provide some clarity for understanding the consequences of direct lightning strikes or indirect lightning strokes, as follows:

mechanical effects of the discharge current as well as the surges resulting from its voltage drop along the discharge path.

Indirect lightning stroke Lightning strike that does not impact directly any part of the network but that induces an overvoltage in that network.

Direct lightning strike Lightning strike impacting a component of the network directly.

NOTE 1: Examples of components of the network are: conductor, tower, substation equipment, etc.

NOTE 2: Consequences of a direct lightning strike include the thermal, magnetic and

NOTE: Consequences of an indirect lightning stroke for electrical installations are the associated overvoltages and the energy content of the incoming surge wave.

Should lightning strike near power lines (indirect stroke), then the magnetic effect of this lightning current rushing to earth

will induce a voltage on anything conductive (i.e. power lines passing through this magnetic field). This is known as inductive coupling – see Fig 1.

The power cable could even be underground and if the lightning struck somewhere nearby a massive amount of current will be injected into the ground.

As the current flows away, a voltage will be induced; this is known as resistive coupling which is the most common cause of indirect atmospheric transient overvoltages. Such transients occur when a lightning strike raises the electrical potential of one or more of a group of electrically interconnected buildings, as illustrated in Fig 2.

Examples of vulnerable interconnections are: ● DNO feed from substation to building ● Submains from building to building ● Supplies to external equipment,

lampposts, CCTV, EV charge points etc ● Telephone lines ● Data and communication lines

Overvoltage control Chapter 443 deals with protection against transient overvoltages of atmospheric origin, or overvoltages which are associated with switching activity within an installation, with Regulation 443.4.1 prescribing: ‘Protection against transient overvoltages shall be provided where the consequence caused by overvoltage could: ● Result in serious injury to, or loss of human life, or

● Result in significant financial or data loss.

For all other cases, the default position is to provide protection against transient overvoltages unless the owner of the installation states that it is not required due to any loss or damage being tolerable. If the client makes this decision, obviously they will be accepting the risk of equipment damage and any consequential loss.

The modern home will have an abundance of electronic equipment which could easily be damaged by overvoltage and for this reason SPDs are often included.

It should be noted that where the word “shall” is used in BS 7671, the implication of that Regulation is a requirement and normative.

Transient overvoltages caused by equipment Overvoltages associated with lightning are severe, but overvoltages associated with switching are more common and in fact can be longer in duration and contain more energy than transient overvoltages of atmospheric origin.

This means that where inductive or capacitive equipment is installed, it is likely that switching overvoltages or disturbances will occur. Regulation 443.4.2 deals with transient overvoltages caused by equipment and advises that protection against overvoltages shall be considered.

Examples of inductive or capacitive equipment likely to cause such disturbances within an installation are:

PROFESSIONAL ELECTRICIAN

● Motors ● Transformers ● Capacitor banks ● Storage units ● High current loads

The examples provided in Regulation 443.4.2 are associated with commercial installations, however consideration for protection against switching overvoltages is equally as important for residential applications. High inrush currents associated with the switching of LED light fittings is one example of equipment likely to cause voltage disturbance and a good example of the type of sensitive equipment that requires protection.

Regulation 443.1.1 explains that switching overvoltages typically have a lower amplitude than transient overvoltages of atmospheric origin. This means that where protection is provided for transient overvoltages of atmospheric origin, it will usually protect against switching overvoltages.

Where the threat of lightning is low and no protection is provided, protection will still be required for switching activity. For this reason, Hager recommends consumer units are fitted with Type 2 SPDs and can supply consumer units with SPD kits factory fitted, saving contractors time otherwise spent installing the individual parts.

IP RATINGS EXPLAINED

Chris Hudson, MD of Hudson Lighting, explains more about the importance of IP68 ratings for recessed outdoor lights and gives a general overview of IP ratings and what they mean.

I

ngress Protection (IP) ratings are crucial for understanding the environmental resilience of electrical fixtures, especially outdoor lighting. An IP rating consists of two digits, indicating the device's resistance to solids and liquids, respectively. However, the specific requirements for outdoor recessed lights demand a higher level of protection, with IP68 being the ideal choice. Before we delve into why IP68 is vital for recessed lights, let's overview the IP rating system: ● IP00: Offers no protection against

contact with any object or ingress of water. ● IP10 – IP40: Offers protection against objects larger than 50 mm (IP10) down to 1 mm (IP40), but no water resistance. ● IP50 – IP60: Fully dust-protected, but offers no protection against water ingress. ● IPX1 – IPX4: No protection against dust ingress but offers water protection against vertically falling drops (IPX1) up to splashing water from any direction (IPX4). ● IPX5 – IPX6: Still no dust protection, but can withstand water jets (IPX5) or powerful water jets (IPX6). ● IP5X – IP6X: Fully dust-protected (IP5X) to dust-tight (IP6X) but offers no water protection.

Lights being tested under water

● IP65 – IP66: Dust-tight and can resist

water jets (IP65) or powerful water jets (IP66). ● IP67: Dust-tight and can withstand temporary immersion in water up to 1 metre. ● IP68: Dust-tight and can endure continuous immersion in water beyond 1 metre. Recessed outdoor lights often face more strenuous conditions, potentially sitting in/under water for extended periods – conditions that would severely challenge IP66 or IP67 rated lights.

While IP66 and IP67 lights offer protection against powerful water jets and temporary immersion in water, neither is suitable for prolonged water exposure, typical for recessed lights. That's where IP68 comes into play.

IP68 rated lights are dust-tight and can withstand continuous immersion in water beyond 1 metre. This makes them an ideal

choice for recessed outdoor lights. It ensures your lighting investment withstands the elements and continues to perform optimally, even under challenging conditions. While the difference between IP67 and IP68 may seem minor, it's this small distinction that significantly impacts the lifespan and performance of your garden lights.

“THERE ARE MANY POINTS” ‘PLUS’ Ruth Devine, ECA Vice President and MD of SJD Electrical, looks at why the Electrician Plus concept will lead the way for the future of competence in our sector.

T

he growing demand for low carbon technologies has led to various misinformed claims that a whole new set of narrow occupations are needed to install them, and this is not the case. A significant proportion of activity is firmly within the skills remit of qualified members of the existing workforce and more specifically, electricians.

Earlier this year the ‘Electrician Plus’ model was launched by TESP to highlight how the role of a qualified electrician is central to the design and installation of ‘green’ technologies such as solar photovoltaic (PV) panels, battery storage systems and electric vehicle charging points (EVCPs).

Once someone reaches qualified electrician status, all that is needed is top-up CPD and qualifications in the relevant new technologies to enable safe, compliant and competent installations.

The new Electrician Plus logo will be used to endorse relevant qualifications to show they are industry approved, in terms of content and assessment, and can only be taken by electricians who meet the industry Level 3 standard.

Safeguarding the industry Sitting at the heart of all this is a focus on competence and public safety; the Electrician Plus model is helping to safeguard against non-qualified and under-qualified personnel undertaking renewable installations and the potential safety and fire risk this poses. The Electrician Plus signposting will be in place to ensure that when electricians train, it’s with robust qualifications.

At a strategic level I was pleased to recently be appointed to the Industry Competence Committee (ICC) set up by the Building Safety Regulator (BSR), who will drive industry to improve competence and increase the skills, knowledge, experience and behaviours of those working across the built environment.

The ICC has a role in advising both industry and the Building Safety Regulator and on matters of competence.

TESP is working closely with the Building Safety Regulator as they finalise

the development of the Mandatory Technical Competencies (MTCs) that underpin Competent Persons Schemes.

It’s encouraging news that the relevant future MTCs are expected to align with the Electrician Plus model, underpinning the importance of safe, quality installations by qualified electricians. Once the MTCs are updated, the Electrotechnical Assessment Specification (EAS) will be updated and reference the valid low carbon qualifications.

It's exciting that the various facets of the industry and higher level government are starting to support the concept of Electrician Plus, with everything finally coming together in terms of quality qualifications, Net Zero, safety and competence.

Across all this activity, ECA Members and the wider industry can and should be at the forefront of the opportunities presented. Where there is public money for upskilling, ECA will be seeking to secure funding for the approved Electrician Plus courses.

SHINING A LIGHT ON ‘THE DARK ART’

W

hen we look back at many of the stories we’ve written about new inventions and genuine ideas that can improve the lives of electrical professionals, the vast majority of tales start from the same place: a front-line electrician or engineer who has encountered an issue in their career and, after discovering that an existing solution doesn’t exist, have sought to fill this particular gap in the market.

44 January 2024

Charlie Butler is no exception. The Essex-based electrician entered the industry as an apprentice at the age of 16, progressing to the stage where he now runs his own electrical firm, alongside his business partner, Paul Wooster. This year, Charlie and Paul added another accolade to their respective CVs after becoming co-owners of BMS Electrical Training.

Explaining more about the inspiration behind the training centre launch, Charlie says: “A few years ago I was offered some work in the BMS sector, and was told that

PROFESSIONAL ELECTRICIAN

Following last year’s launch of the UK’s only training campus dedicated to the principles of BMS electrical installations, we talk to Charlie Butler, Co-Founder of BMS Electrical Training, to learn more about how the training centre is helping professionals to take ‘control’ of their BMS knowledge. my existing skill set would allow me to do a competent job. I’ll be honest and admit that I didn’t have a clue about BMS systems at the time so I went about researching what type of specialist training was available in this area – there was nothing.

“There are no standards and regulations that fundamentally govern the BMS industry, so you’ve essentially got an un-regulated industry with very little capability for professionals to improve their knowledge and skills because of the lack of training on offer. With the launch of BMS Electrical Training, we hope to fill some of the void.”

Four years in the making, the BMS Electrical Training campus officially opened in February of last year. Housed at a 500 sq.ft facility in Writtle, Essex, the centre enables delegates to arrive with limited knowledge and leave with the confidence that they can translate drawings, understand the devices used and the positions of such devices, and have a broader understanding of general best practice for quality BMS installations.

Charlie says: “Electricians will look at a panel drawing, but may have no clue as to what it might mean and how different elements can affect an installation.

044_PE_JAN24_Layout 1 01/12/2023 14:19 Page 45

“Delegates are taught how to read panel drawings, the role of different accessories, and how to expertly wire and install all devices on an air handling unit, for example.”

He continues: “In our workshop, which is fitted out as a fully working plant room, we have the luxury of being able to simulate site conditions to aid our training. We will walk trainees through how to locally isolate a piece of plant, and prove it is safe to work on. We also have the ability, with the aid of our fully working BMS panel, to explain to trainees how to test if the panel is energised, and demonstrate that some circuits remain energised, even when the panel isolator is switched off.”

Although the team at BMS Electrical Training plans to add extra modules and courses to enrichen its offering over time, two fundamental courses have been the bedrock behind the centre’s first year in business: a one-day safe isolation course and a three-day advanced course. A further feather in the cap comes with the news that both courses have recently achieved City & Guilds Approval, which adds more validation and credibility to the offering.

1

Safe isolation within the BMS industry This course will teach trainees how to test circuits and panels safely, to identify if they are energised, or safe to work on, providing them with the necessary skills to understand and implement safe isolation procedures.

From a practical perspective, delegates are shown how to isolate, test and lock off: ● a device (such as a boiler, pump or a fan) ● a circuit emanating from a BMS panel ● a BMS panel.

2

Three-day BMS electrical training On this more advanced course trainees will discuss what BMS is, be shown various control cables, and learn about pipework to understand how to identify the correct BMS devices. They will gain an understanding of the role and typical components of a BMS, the fundamentals of control theory, and how BMS can be used to optimise building performance. Attendees will be taught where each device on a typical Air Handling Unit should be fitted, which cable would suit the installation best, how the device should be installed, and what each device actually does.

BMS – a bright and profitable future Both courses have proved popular since launch, with over 100 delegates having undertaken the three-day course to date and electricians, commissioners and apprentices coming from far and wide to take advantage of training expertise that simply wasn’t available previously. Having added Jon Ruscoe to the business as the lead instructor, BMS Electrical Training and its delegates now have over 30 years of BMS experience to call upon.

Interestingly, although we’ve stated earlier that BMS remains a largely unregulated sector, strict statutory

guidance dictates that all new and renovated buildings require an intelligent BMS system – proof, if any were required, that this is a healthy and future-proof area that can be very rewarding for professionals with the correct skills.

Charlie reaffirms: “There’s an endless opportunity moving forwards. Refurbished new builds all have a management system of some sort, so that makes BMS skills and understanding all the more relevant.

“We’ve strived to offer a brand-new syllabus to the industry – one that we believe has been needed for some time.

With our mixture of classroom learning and a fully functional plant room, we offer something unique. Our courses have been designed to aid engineers already working in the BMS industry, as well as giving those that might be new to the sector a head start.”

He concludes: “It’s not a dark art.

Education should be available to everyone. The skill set is there within electrical professionals, it’s all about individuals now being given the tools to learn correctly.”

THE KNX FACTOR

T

oday’s building automation and smart home ecosystem presents electrical contractors with a transformative opportunity.

Just as the emergence of LED lighting changed the game a decade ago, the rise of intelligent building systems powered by KNX technology is rewriting the rules of electrical installation and management. For electricians and electrical contractors keen on riding this wave, investing in KNX training and certification isn’t just an added advantage – it's a business imperative.

With the demand for professionally installed smart homes only growing, there is an obvious opportunity for electricians to undertake training to sell, specify and install KNX smart home solutions. The biggest benefit of KNX training for electricians is not only adding a new skill but also making a move to differentiate their business in a busy market.

What is KNX? KNX is the only global open standard for commercial and residential building automation, enabling seamless communication between devices from over 500 different manufacturers. It is also secure and provides both wired and non-wired solutions. From lighting and blinds to heating, ventilation, and security systems, using KNX enables integrators to bring diverse building functions into a single platform.

Systems created with KNX are endlessly adaptable and interchangeable due to its backwards compatibility. This enables a client to start with automated lighting and add HVAC, security, blind control, assisted living devices and weather stations at a later date if they choose. If a device fails or a different functionality or aesthetic is required, individual components can be exchanged without the need to replace the whole system.

Why should electrical contractors care?

A growing market The smart building sector is burgeoning with energy conservation, sustainability, and user-centric experiences becoming paramount. To take advantage of the surge in smart home growth, electrical contractors should consider KNX as it is a wired whole home solution that is ideally suited to an electrician's skill set.

46 January 2024

PROFESSIONAL ELECTRICIAN

Sophie Thomas, Marketing & Business Manager at Ivory Egg, discusses the value of KNX training and certification for electrical contractors.

Diversification Diversifying into KNX installations opens doors to a broader clientele – from homeowners wanting a connected living experience to businesses looking for efficient building management solutions.

Competitive edge As more contractors join the KNX fold, those without the requisite skills risk getting left behind. With KNX certification, contractors not only showcase their expertise but also can build trust with a new and expanding pool of clients.

What is the value of KNX training and certification?

Comprehensive skill set KNX training courses, whether basic or advanced, offer an in-depth understanding of the KNX architecture, programming, and troubleshooting. This ensures contractors can handle complex installations with confidence.

Access to a global community Being KNX certified means joining a community of over 100,000 partners worldwide. This network offers

046_PE_JAN24_Layout 1 01/12/2023 09:29 Page 47

unparalleled opportunities for collaboration, learning, and business growth.

Stay updated The world of KNX is dynamic. Regular training ensures that contractors are always abreast of the latest technologies, trends, and best practices.

Increased profitability With specialised skills, contractors can command better prices for their services. Moreover, as systems built on KNX often entail more comprehensive work than traditional setups, there's potential for higher revenue.

Following completion of the basic KNX course with BEMCO, one delegate commented: “For us, undertaking this basic KNX course is just building on what we offer to the customer. We already have a business and marketing plan in place, and we know where we’re going as a business. This just adds to our offering and ensures that we’re keeping ahead of technology and that what we’re putting in is robust".

Future-proofing your business In a world where technology is evolving at breakneck speed, businesses that do not innovate risk obsolescence. As governments and organisations globally rally for greener solutions, KNX-certified contractors will be at the forefront of implementing energy-efficient building automation systems.

According to Jason Aldous of Aldous Systems, it’s an obvious choice: “When you start talking to our students about the competitive advantage of offering a standards-based solution over a proprietary solution to end customers it almost becomes a no-brainer to be offering KNX-based solutions all the time.”

The KNX landscape offers a world of opportunity – be it in terms of revenue, business growth, or staying relevant. By investing in KNX now, contractors can not only secure their present but also future-proof their business for years to come.

We catch up with the team at XS Training to find out more about why solar PV panels and battery storage will herald a new dawn of opportunities for electrical installers.

THE NEW DAWN

I

n the Professional Electrician & Installer 2023 Reader Survey, which was published at the end of last year, one of the questions asked was: “Which of the following areas would you be keen to undertake training in?”

The top four responses, by a long way, were all focused around green, future energy resources. This is, of course, no great shock as our industry is only going one way. The upward trajectory curve may be 'flatter' than it was imagined at this point five years ago (due to a number of factors) but that it will start to rise much more steeply in the near future is not in doubt.

A huge factor in this accelerated growth is not only that green energy sources such as solar PV panels are becoming increasingly efficient and less expensive, but also we now have much more accessible and reliable methods to

48 January 2024

store any excess produced power for when we most need it. According to Chris Hewett, Solar Energy UK Chief Executive, domestic solar installations almost doubled in 2022 compared to 2021. The data for 2023 is likely to show that this rise has continued.

Quantity over quality?

As is common in any industry, when things become more popular or when grants are available to reduce installation cost, quantity of installations often becomes more important than quality installations. It doesn’t take much digging on the internet to find horror stories or see images that evidence this. Pictures of poorly strung cables rubbing against roof tiles, burnt out AC isolators being used on the DC side of the installation and even videos of fires where the emergency services can do very little to stop the blaze.

PROFESSIONAL ELECTRICIAN

For existing electricians looking to embrace the green technology revolution and start installing PV and EESS, a form of accreditation is required. To gain this, they will also need to gain relevant qualifications in these areas.

These courses will go through the stages of designing an efficient system with the requirements of the customer, such as how many panels can be fitted and what the long-term results of this will provide in terms of energy saving from the grid. They’ll also cover how to work out why storing this energy can give a reduction in the reliance of buying in energy from the national grid.

As ever, once the system is designed it then needs to be installed correctly.

Regulatory compliance The courses highlight the requirements set out in regulations for the use of the correct protective devices and isolation points along with how to carry out the appropriate tests to certify the installation in accordance with MCS and National Grid Connections. Without these it might not be possible for the customer to be paid for any of the power they export back to the National Grid.

XS Training will soon be offering courses for both the installation of solar PV panels and Electrical Energy Storage Systems (EESS). These will be delivered from the awarding body LCL and is one of the current qualifications required to gain MCS accreditation.

PASS THE ‘REMOTE’

Andy Reakes, Director of Growth & Development for JIB and ECS, explains how the organisation’s remote invigilation system offers a more flexible service for people taking their industry assessments.

J

anuary 2021 was an uncertain time for the world. The UK was in the grip of a third national Covid-19 lockdown with businesses, public buildings and shops closed. Our ability to move around and visit places – for business or pleasure – was severely limited.

The Joint Industry Board (JIB) moved swiftly throughout the pandemic to support companies and individuals with getting to site in a compliant manner, provided guidance on how to work in line with site operating procedures, provided flexibility for working patterns and updated insurance cover to ensure those who could still work were able to do so.

While meetings and some classes could take place online, for those working towards a qualification, pursuing an apprenticeship, or undertaking any kind of assessment, there were concerns about how tests and exams could be carried out fairly and in a compliant manner with national restrictions.

ECS card holders are required to pass the ECS Health, Safety and Environmental (HSE) Assessment or hold a valid exemption. This would require attending one of the centres located around the UK but, during the pandemic, travel was restricted, and centres had faced a number of challenges, from closure to severely limiting the numbers and way in which assessments were being undertaken.

50 January 2024

In response, the JIB launched a pilot for an online invigilation service for its ECS HSE Assessment. Initially available to employers from January 2021, it was extended to individuals, through their MyECS account, in November of that year. It was then further developed to include a suite of assessments including: Fire; Fire & Emergency Lighting; Security, Fire & Security; and Network Infrastructure Awareness.

Upgrades to the system have been ongoing since its launch, to simplify processes and improve user experience.

In addition to on-screen guidance and written instructions before the assessment, there’s a video available on the ECS website with step-by-step instructions on how to set up and undertake an online test. This remote invigilation system has been incredibly successful with more than 50,000 assessments completed using the simple, online software.

PROFESSIONAL ELECTRICIAN

Greater flexibility Centres are still available for those who prefer to take the assessment with an invigilator and, in some cases, this may be more appropriate. However, the remote invigilation service means ECS card holders and employers now have the option to take their tests without having to attend in person. As well as saving time and travel costs, this means reduced waiting time and less need for advanced planning.

This system is powered by world class technology for automated invigilation, using Artificial Intelligence (AI)-powered, behavioural monitoring and verification tools.

Candidates have the freedom to complete their assessment, securely and safely, at a time convenient to them, with no programs to download or browser extensions needed. All that’s required is a laptop or desktop with a webcam and a stable internet connection.

Instead of an invigilator watching a candidate take their test, automated online monitoring software using an AI program is used to verify the identity of the person and then to constantly monitor and record their performance. The monitoring software makes use of the candidate’s webcam, microphone, keyboard and mouse. If at any time the system detects unusual activity during the assessment, the candidate will be automatically flagged for moderation and can then be reviewed by a member of the ECS team.

050_PE_JAN24_Layout 1 01/12/2023 09:37 Page 51

Taking your assessment To take an ECS assessment using the remote invigilation system you will need to be in a room where you will not be disturbed. There must not be anybody else in the room with you for the duration of the test. You will need a desktop or laptop computer set up in a place where you will be comfortable. The best option is to sit at a table or desk.

If you are using a laptop, make sure that you have sufficient power to complete the test. It is highly recommended that your laptop is connected to the mains power supply. The computer you are using will need a working webcam pointing directly at you, so that your face is in the centre of the screen. Ensure that there is a plain background behind you.

You will also need a stable internet connection and an up-to-date web browser, such as Chrome or Edge, running on the computer you are using.

We recommend that the computer you use is a standalone with a single monitor connected to it. If you are unable to disconnect any additional monitors from your computer, you must remember to remain solely in a single browser tab and not stray anywhere else on the computer.

If you do not stay in the single browser tab, where the assessment is available, the system will fail you automatically.

“This remote invigilation system has been incredibly successful with more than 50,000 assessments completed.”

The company is a worldwide provider of hard and soft facilities management as well as offering smart and integrated services for mechanical/electrical, data cabling and networks solutions in the industry.

Mike Stark, Director of Data Cabling and Networks for Atalian Servest AMK, said: "ECS remote invigilation revolutionises assessments, saving

businesses invaluable time and money. By seamlessly integrating cutting-edge technology, it ensures a secure, convenient and cost-effective experience.

“Embracing this system means streamlined processes, reduced administration and significant cost savings on physical infrastructure and personnel.

Companies now invest more in their core activities, driving innovation and growth.”

He concluded: “Embracing ECS remote invigilation isn't just a choice, it's a strategic advantage, empowering businesses to focus on what truly matters, fostering efficiency, and maximising profitability in today's fast-paced world.”

Recent topics included the current requirements for circuit protection equipment, and updates on AFDD and SPD installations.

“Scolmore’s participation in our employer engagement event, which took place in October, received a very high level of great feedback from both students and staff. Neil McManus was singled out for delivering superbly informative CPD sessions on the latest amendments and requirements for circuit protection, and he showcased some of the latest products to be introduced by Scolmore.

“The support provided by Scolmore Group positively enhances the training delivery and learning experience for all our students. The opportunities for them to interact with outside companies during their college training contributes to their whole learning experience.

Geoff Shaw, Lecturer at Cardiff & Vale College, concluded: “We’re extremely grateful to Scolmore for the continued support on offer which has enhanced our provision and opportunities for our learners.

“With the teaching materials and training provided, it is not just students who have been given an understanding of Click Smart, ESP and Ovia lighting design products, but our staff have also benefited with the practical examples that have been demonstrated. We talk around these different product ranges and solutions in our lessons when explaining to students the areas of smart homes, lighting design and security systems.

We’ve been especially impressed with the ease at which the Click Smart home products can be retrofitted into an installation.

“We’ve always used Click products as we find them to be of very good quality and value, which in turn has helped us reduce our budget. At the same time we have increased our knowledge of other ranges, such as Unicrimp Q-Nect lever connectors and Elucian consumer units.

“We feel that it is important that students have the opportunity to train with high quality equipment, and the Scolmore Group products definitely meet these requirements.”

Lucas Whitmer, Product Development Engineer at MK Morse, offers five top tips to get the most out of your hole saw.

A ‘SAW’ SUBJECT 1

CHOOSE THE RIGHT HOLE SAW FOR THE JOB

Whether undertaking general purpose work or cutting a very specific type of material, you should know the best hole saw for the applications you plan to tackle: MHS is the most effective general-purpose tool; good for regular electrical boxes, mild steel and wood, or even drywall.

Carbide tipped hole saws perform in abrasive and hard-to-cut materials – stainless steel, fibreglass, or computer board, for example – that standard MHS blades can’t handle.

Carbide grit is ideal for coarse, masonry-style material like cinderblock, brick, and stone, and is perfect for recessed lighting.

Diamond grit is for finer grit materials, like ceramic tile, granite, glass block, cast iron, or materials that can ‘tear out’ like laminate flooring.

2

USE THE CORRECT SPEED

Not all materials are created equally; you must adjust your speed based on your application. When cutting wood, you can give it gas and run it wide open at 1500 RPM. As you move to harder-to-cut materials, slow down your

RPM to let the teeth work optimally and to prevent tool failures like tooth strippage and excessive heat. Keep an eye on your speed setting on your drill. Aluminum is fairly easy to cut, so you can run around 400 RPM. Mild steel requires a little lower RPM, around 150. Stainless steel is hard to cut, so you should run at about 50 RPM. Not sure how to gauge? If you can still read the logo as the hole saw spins, you’re going at about 50-60 RPM.

3

DON’T OVERLOOK LUBRICANT

Whenever you’re able to, we recommend using lubricant to get better life out of your tool. Lubrication will help keep the teeth cool during the cut and prolong the life of the teeth. An easy application method is to use your hole saw to cut a slug out of a sponge. Dip the round sponge in lubricant and put it up inside the blade. As the hole saw spins, the lubricant will be drawn out of the sponge and down the sides to the teeth.

You can still cut effectively without lubrication, but it will increase the life of your hole saw in certain applications.

4

UNDERSTAND PILOT BITS AND THEIR IMPORTANCE

5

AVOID ACCIDENTAL THREAD LOCK

A pilot bit gives you an anchor point when you start your cut, ensuring accurate hole placement and a smoother finish. There are several pilot bit types to choose from. A standard high-speed jobber style bit is the most general purpose. Spade carbide-tipped masonry bits are for going through cinderblock and brick, while a spring-loaded auto pilot bit works best with diamond grit hole saws.

Thread lock can happen when you use a small (non-pin drive) arbor on a large diameter hole saw. The torque from the tool can twist the hole saw onto the arbor, making it challenging to remove. A pin drive arbor applies the torque from the drill into the pins, instead of the arbor threads, using it to spin the hole saw and prevent the arbor and hole saw from locking together.

For 60 years, Morse has been manufacturing a wide range of innovative cutting solutions. Whether you need to drill holes, cut metal using power tools, or saw metal in a factory, Morse has the right blade for the job.

THE POWER OF ONE

Can ‘same-brand’ solar systems increase time-efficiency and income for installers? V-TAC discusses.

S

olar energy’s promise of clean, renewable energy has captured the world's attention.

Many electricity consumers now prefer solar for its renewability, climate-friendliness and cost-effectiveness.

As the solar industry continues to grow, one crucial element often overlooked is the importance of using components from the same brand in solar installations.

Mixing and matching solar components from different brands has proven to have enormous disadvantages, although they’re rarely talked about.

One of the most significant disadvantages of using components from different brands in a solar system is the potential for ‘compatibility crisis’. Solar panels, inverters, and batteries from various manufacturers may not work seamlessly together, leading to inefficiencies and reduced overall performance. This can result in low energy production and financial losses for the system user and consequently, loss of productive time for the installer.

Furthermore, mixing of solar components can create the hassle of having multiple warranties with different terms and conditions. This can be a nightmare for installers, when it comes to

60 January 2024

maintenance and repairs. Trying to help the client manage an array of warranties can be time- and cost-consuming, especially if a system fails, and multiple manufacturers are involved.

By design, solar systems should operate at peak efficiency when all components are carefully chosen and integrated.

Additionally, mismatched components can lead to suboptimal performance, reducing the system's overall energy generation potential. This not only affects the system owner's return on investment but also undermines the sustainability goals of the solar industry. As a result, the installer would have to go over a task several times that could have been carried out just once, amounting in a waste of man hours.

PROFESSIONAL ELECTRICIAN

Same brand solar systems: the V-TAC perspective One company that exemplifies the advantages of same brand solar components is V-TAC Technologies. V-TAC has made a name for itself in the solar industry by providing a complete range of solar components, including solar panels, inverters, and batteries, all under the same brand umbrella. This integrated approach offers several unique selling advantages to installers and end users alike.

Same-brand solar systems work seamlessly together, providing optimum performance and energy production. It also allows installers to easily manage warranties for the entire system, reducing the bottlenecks associated with multiple warranties. By utilising a same-brand

060_PE_JAN24_Layout 1 01/12/2023 10:03 Page 61

solar system you’re ensuring quality after-sale support for efficiency and effectiveness, and customers can, with a single point of contact, get assistance whenever they need it.

Dinesh Sajnani, Co-founder of V-TAC, says: “It’s important for installers to educate their clients on the importance of a same-brand solar system. To enhance effectiveness, having all solar components from one brand helps the inverter and battery to work in-sync with each other.

“When a solar system’s inverter and battery fail to understand each other, the system cannot perform to its potential.

We’ve taken it upon ourselves to lead this crusade for a one-brand solar system, as our way of further contributing to a successful takeover of renewable energy as a mainstay in power generation. We do this to ensure our customers enjoy their products with ease, comfort, and satisfaction.”

Additionally, V-TAC’s UK Sales Director, Kashish Amarnani, explains that the company preoccupies itself daily with

making sure that customers are given the best after-sales support. He emphasises that V-TAC’s solar systems provide for seamless interaction among key components which he says are created to synchronise with each other.

According to Kashish, if all components, such as inverter, battery and panels are from the same quality brand, end users and installers can be rest assured of the longevity of their installation.

He explains: “At V-TAC, we believe that solar components such as panels, inverters and batteries, are meant to all work seamlessly together. This also ensures that

the system can be easily coupled together in a plug-and-play manner. Although V-TAC's inverters, batteries and panels are versatile enough to work with third party equipment, we also always recommend to installers and end users to stay with us for all their solar needs, as this guarantees optimum performance. With this approach, users can have one system from the same brand that meets the highest quality standards.”

POWER TO YOU

Chris Murray, Digital Power Tool Training Manager for Bosch, talks us through some of the flagship technologies involved with the brand’s most advanced platform and power tool range to date.

B

osch has a long and illustrious history across multiple sectors, but the company’s first point of departure from its original automotive roots was power tools. Indeed, the German manufacturing giant has an excellent heritage in SDS hammers in particular – having invented the concept of SDS itself – and can even claim to have developed the world’s first rotary hammer.

Today, around 80% of professional end users are purchasing cordless, with the levels of power and convenience in battery powered solutions improving exponentially

62 January 2024

in recent years. Indeed, performance is now equal to or greater than corded equivalents, even when using a 12 V system. Of that aforementioned 80%, around 90% of those cordless users are estimated to be on an 18 V platform.

With the goal for the tradesperson to make use of one system – where all their batteries are compatible with the tools they already own and use – loyalty to a battery system now plays a greater part than ever in the choice of power tool brand.

More than just batteries It's not all about batteries, of course, because Bosch is continually developing its technologies, and the manufacturer has been systematically updating its existing products with brushless motor models. As a result, the manufacturer can now point its customers towards a complete range of brushless combis and drill drivers.

The latest entry level brushless 18 V cordless combi, for example, is the GSB 18V-45 – where the 45 designation represents Newton Metres (Nm). As an indication of the additional performance accrued from brushless consider that it’s a lot smaller, but still more than twice as

PROFESSIONAL ELECTRICIAN

powerful as its brushed predecessor, which could generate only 21 Nm of torque.

Added to that is the GSB 18V-55, GSR 18V-55, GSB 18V-60 C, GSB 18V-90 C, GSB 18V-110 C and GSB 18V-150 C – all with brushless motors. Brushless motors are more efficient and can offer up to 30% longer runtime. With no carbon brushes to wear – and fewer moving parts – the lifetime is up to twice as long, and they’re more robust as machines.

Another considerable claim to fame is the first power tool with lithium-ion battery power. Introduced in 2003, the IXO ran a single 18,650 cell – 18x65mm in dimensions – and was a 1 Ah battery. The advantages of lithium-ion batteries are now well known,

062_PE_JAN24_Layout 1 01/12/2023 11:10 Page 63

contacts, conducting heat away from the side of the batteries. All of that technology comes together to produce a battery that is capable of discharging heat from all four of its sides.

of course. They have very good power output and energy density. They can be charged quickly and discharged equally swiftly on heavy duty applications. The nemesis of any lithium-ion battery, however, is heat. Any battery of this type will heat up with use and its mitigation has required further technological innovations.

As a result, Bosch was very quick to pair lithium ion with battery management systems and electronic cell protection that will stop the machine if it’s in danger of overheating. Essentially, it regulates the amount of charge, discharge or current coming out of the battery, giving it up to four times longer lifetime and, again, is all part of a commitment to ensure that a power tool user’s investment is protected.

forward in battery technology. Instead of utilising 18,650 cells that will deliver 45 A of current from a dual layer battery, it features an upgrade to 21,700 – or 21x70mm in dimensions. A physically bigger battery means it will store more energy and more current can be drawn from it – but why the need?

What end users have been demanding for some time is battery power that could run much larger and more powerful machines. Whilst its competitors have gone down the dual battery route, with two 18 V batteries powering a single tool, Bosch has rejected that solution and there are sound technical reasons for doing so.

Instead, the ProCORE battery platform will do the job very nicely with a single 18 V unit. A dual layer battery featuring 21,700 cells 90 A of current is available – double what was previously offered on the Coolpack generation. That increase requires a new battery design with copper contacts that benefit from lower internal resistance and better electrical transfer.

The original HDPE Coolpack configuration was also redesigned so that every cell is fully encapsulated in the material. Moreover, a Thermo Plastic Elastomer (TPE) sits alongside the copper

ProCORE and BiTURBO Armed with the new ProCORE battery, Bosch can power the bigger, more powerful machines that make up the new BiTURBO range. Not only does it promise corded equivalent power with just one 18 V battery but machines that can equally outperform tools in higher battery voltage classes.

BiTURBO tools also benefit from the latest safety features, including KickBack Control, Drop Control and Vibration Control. The range is flexible enough to be fully compatible with the rest of the Bosch 18 V battery platform and they can be run on a standard 18 V battery. With Bosch the message is clear: just one 18 V ProCORE battery will suffice on heavy duty applications.

The ProCORE range of batteries now includes a 5.5, 8, and 12 Ah unit. It’s important to note that the 4 Ah ProCORE is lighter and more compact than the standard Coolpack 18 V 4 Ah. It can do that because the aforementioned 21,700 cells can be arranged in a single layer, as opposed to a double layer of 18,650 cells in the Coolpack.

At the same time, if you need the maximum performance, the 4 Ah ProCORE battery isn’t recommended for a BiTURBO machine. The batteries that have been specifically designed for high draw applications would be the 5.5, 8 and 12 Ah.

BOILER SUITS

A

s the world faces the pressing challenges of climate change and environmental deterioration, countries are racing to reduce their carbon emissions and transition to more sustainable energy sources. The UK, in its pursuit of a greener future, has set an ambitious goal to achieve net-zero greenhouse gas emissions by 2050.

Achieving this target necessitates significant changes in how we heat our homes, and air source heat pumps (ASHPs) are often hailed as a beacon of sustainable heating. However, it's important to recognise that ASHPs are not a one-size-fits-all solution for every home in the UK. In cases where ASHPs are not a suitable option, electric boilers emerge as a compelling alternative to help us reach our net-zero goals.

Understanding the challenge The housing stock in the UK is incredibly diverse, with properties ranging from centuries-old stone cottages to modern, energy-efficient homes. This diversity presents a significant challenge when it comes to selecting the most appropriate heating solution. While ASHPs have received attention for their energy efficiency and carbon reduction potential, they may not always be a suitable choice for every home due to several factors.

Inadequate insulation One of the primary considerations for ASHP suitability is the insulation of the property and heat loss credentials. ASHPs operate most efficiently in well-insulated homes.

Older properties, in particular, often lack the necessary insulation, making it difficult for ASHPs to provide sufficient heating without significant energy consumption.

Space constraints ASHPs require outdoor space for the

66 January 2024

installation of the outdoor unit. Some properties, such as city apartments or densely packed urban homes, simply don’t have the space required for ASHP installation.

Temperature extremes In areas of the UK where winter temperatures often plummet well below freezing, the efficiency of ASHPs can sometimes be challenged in maintaining optimal indoor temperatures.

High initial costs The installation of ASHPs can be costly, especially when significant retrofitting is required for older homes. For homeowners on a tight budget, this can be a major obstacle.

Aesthetic considerations Some homeowners may be reluctant to install an ASHP due to concerns about how it may affect the appearance of their property, particularly in historic or architecturally significant buildings.

PROFESSIONAL ELECTRICIAN

We catch up with the experts at Electric Heating Company to find out more about why electric boilers can serve as a compelling alternative when air source heat pumps may not be the perfect fit for a customer’s home.

Electric boilers – a versatile alternative The journey to achieving net-zero carbon emissions by 2050 in the UK is multi-faceted, with the choice of heating playing a vital role in this endeavour.

While ASHPs are an excellent choice for many homes, they may not be universally suitable. Electric boilers, with their versatility, efficiency, and affordability bridge the gap, offering a pathway to net-zero emissions for homes that can’t accommodate ASHPs. These solutions align with the UK's commitment to a cleaner energy grid, making them an environmentally responsible choice.

Electric boilers have evolved significantly in recent years, offering greater efficiency and environmental benefits than ever before. Other key reasons to consider electric boilers include: Versatility Electric boilers are highly versatile and can be installed in a wide range of homes, including those with inadequate insulation or limited indoor space. They’re also suitable for properties with varying heating requirements, ensuring they can adapt to different household needs.

No outdoor unit required Unlike ASHPs, electric boilers don’t require an outdoor unit, making them a practical choice for properties with limited space, such as urban apartments or terraced houses.

Cold weather performance Electric boilers are not affected by external temperatures, ensuring consistent heating performance, even in

066_PE_JAN24_Layout 1 01/12/2023 10:10 Page 67

the coldest regions of the UK. This makes them a dependable option for homes in areas with extreme winter weather.

Cost-effective Electric boilers tend to have lower up front installation costs compared to ASHPs, which may require extensive retrofitting in some cases. This affordability can be a decisive factor for many homeowners.

Minimal disruption Installing an electric boiler typically involves less disruption to the home and can often be integrated into existing heating systems, minimising the need for extensive renovations.

Aesthetic considerations Electric boilers are compact and can be installed discreetly, ensuring they don’t detract from the aesthetics of the property.

Environmental benefits While it's true that electric boilers run on electricity, and the carbon footprint of heating largely depends on the source of that electricity, The Electric Heating Company is committed to environmentally responsible solutions.

The UK has made substantial progress in decarbonising its electricity generation, with an increasing use of renewable

energy sources. As a result, the carbon intensity of the electricity grid has decreased significantly.

Electric boilers from The Electric Heating Company benefit from this shift towards cleaner energy sources, making them a greener choice compared to traditional gas or oil boilers. As the UK continues to invest in renewable energy infrastructure, the environmental advantages of electric boilers will only become more pronounced.

Moreover, electric boilers offer the potential for load management and demand response programs. These systems can be integrated with smart meters and controls to optimise energy use, reducing the strain on the grid during peak times and helping balance energy supply and demand.

Policy support and incentives EHC also believes local authorities should promote electric boilers by offering guidance and information to homeowners, helping them make informed decisions.

Public awareness campaigns can educate the public about the benefits of electric boilers and dispel any misconceptions about their environmental impact.

Conclusion The race to achieve net-zero carbon emissions by 2050 is a monumental challenge that requires a holistic approach to reducing greenhouse gas emissions across all sectors. The heating of homes and buildings is a significant contributor to carbon emissions in the UK, and transitioning to sustainable heating solutions is crucial.

The Electric Heating Company offers both ASHPs and electric boilers, providing a dual approach to achieving net-zero carbon emissions. The comprehensive range of heating solutions ensures that every home can find the perfect fit, regardless of its unique challenges. EHC’s award-winning teams can further assist customers in making an informed decision that ensures their home's heating runs on no fossil fuels and can achieve net zero goals.

PRODUCTS & BUSINESS SOLUTIONS

GOING OVER THE TOP

T

he UK cable management specialist has developed the patent pending Ultra Cable Cover for stakeholders seeking a convenient and inexpensive solution for on-street EV charging. The Highways Act 1980 makes anyone who places a cable or similar across a pathway, in a way likely to cause a danger, without giving adequate warning of the danger, liable for up to a £1,000 fine.

Not wanting to trip up on cable litigation risks, the conundrum is evident in ‘imaginative’ responses. These include schemes by lamp-post charge providers, and others needing to levy tariff premiums on EV owners, to payback significant investment costs in the new infrastructure.

Consider the disruption too of having streets ripped up to accommodate charging bollards! At least hangman-style overhead apparatus, however impractical, can enable draws from residential tariffs.

D-Line recognises also how expensive steel gulley options have no doubt inspired alternative ducts, some with hinged lids, intended as a conduit for kerbside charging. Aside from the user mobility required to open the lid-cover for cable insert, consider how narrow terraced streets often require car parkers to straddle the pathway.

These car owners demand versatility for their EV cable to exit over the pathway, left-or-right side according to vehicle location, with any lid that protrudes around the cable being a danger.

In the drive to accelerate EV ownership, against a background where insufficient on-street charging is being cited as the UK’s biggest challenge to EV adoption, and where six million car owners have no driveway, step forward D-Line.

An accident waiting to happen?

With seemingly no practical options to safely contain EV cables (up to 18mm diameter), some authorities are overlooking that traditional cable protectors are usually rigid and inflexible, often over 40mm high with 40˚ incline slopes, and easy to open lids. While these can protect a cable, to pedestrians they can be accidents waiting to happen.

Court judges have stated that ‘footpaths are not expected to be as smooth as bowling greens’, but any step obstacle higher than 20mm threshold brings obvious danger.

D-Line’s Ultra Cable Cover addresses all such reservations, being produced from a flexible material that is ‘pavement-friendly’ to follow sloping paths

and easily cut to shorten if needed. It is ‘user-friendly’ too, and uniquely reversible.

Cables can be covered by the solid top when rolled out, or the cavity can be open-top style. Open-top allows cables to be easily pushed-in and pulled-out from standing position, enabling cable exit from left-side or right-side, according to vehicle position. The Ultra Cable Protector can be screw-fixed for security, or stored in coil form if used temporarily.

The pedestrian friendly 8˚ slope is so shallow that the step is hardly noticeable, being less than 20mm height when cable is inserted. In open-top, the cavity closes to only 10mm aperture on cable removal.

While homeowners should confirm usage permissions from local authorities, EV charge point installers are still prudent to seek from customers a disclaimer from any cable trip liability. The Ultra Cable Cover does, however, give utmost respect to all.

Available in black or grey options, every 2 metre length has yellow hazard stripes and every length is supplied with a hazard warning sign for easy hook-and-loop attachment around the cable. The Ultra can save need for cable path groundworks on private land, with obvious benefits for use in all areas where cables cross with busy foot traffic.

Products IN PRACTICE

Dimming modules are right on ‘Point’ The Enkin team has recently played a major role in the renovation of a significant period property overlooking the Falmouth coast: Clay Point.

Enkin worked closely with the client on the lighting project, according to the brief provided. This centred around creating ambience and visual impact in line with the building’s unique period character while introducing a technologically modernised lighting system to benefit contemporary family life. A key element of this was replacing the outdated dimming knobs previously installed throughout the property.

Clay Point represented Enkin’s first full-house installation using the brand’s award-winning dimming modules.

Installation Installation at Clay Point was led by Withers Building & Electrical using products by Enkin.

A focal point of the brief was the large scale, open plan kitchen dining room.

Frequently used for entertaining as well as cooking, the client required lighting that was both atmospheric and functional, coupled with a high degree of control to be able to switch between the two. The resulting lighting plan called for layered lighting and multi-locational dimming capability, and so Enkin’s IDM150 in-line dimming modules were selected for the task, fitted behind toggle switches.

The in-line dimming module is designed to sit behind a retractive toggle switch, allowing for true multi-location dimming. This combines the sought-after convenience of dimming from multiple positions around the room, and the desired aesthetic for the traditional design of the kitchen.

70 January 2024

The orangery – an open plan, double height glasshouse with distinct period attributes that is frequently used for family gatherings – also held high importance for the client. The client had previously struggled to get the lighting right due to there being “so many angles and no clear centre” to the space. This insight led to a customised lighting installation of statement period-style pieces alongside cleverly situated accent lighting, all controlled by Enkin’s in-line dimming modules.

With the benefit of the IDM150 being concealed behind a dimming toggle switch, the dimmer once again remained in keeping with the architectural detailing of the room, complementing the client’s carefully coordinated décor scheme. The convenience brought by the multi-location dimming functionality was well-suited to such a large space, adding a technological advantage to the period-style space.

Product benefits For the electricians responsible for fitting the dimming modules at Clay Point, the additional ease of installation and safe,

PROFESSIONAL ELECTRICIAN

reliable technology gave them the confidence that they’d delivered to the brief. For the client, the dimming toggle switches provided a practical modern lighting solution without having to compromise on the period aesthetic of the newly renovated home.

The multi-location dimming functionality of the IDM150 supported the requirements for adjusting between ambience and task lighting in large rooms.

The versatility of the module meant that it could be fitted behind switches and sockets in a finish of the client’s choosing, while Enkin’s silent and flicker-free technology ensured seamless lighting control and uninterrupted ambience.

A glowing testimonial On working with Enkin, Aaron Withers of Withers Building & Electrical, said: “I was really impressed. Installation was quick thanks to the simple setup instructions, and I could easily set all the parameters required. The compatibility with the luminaires was great and there was no annoying flickering or buzzing. The Enkin technical team was top notch too – quick to help and very knowledgeable when we had questions.”

The happy client Enkin’s client, the owner of Clay Point, said: “We now have an amazing arrangement of lights in our home, and we simply couldn’t do without our dimming toggles – they work brilliantly, and we haven’t had a single issue.”

CAUGHT ON

C A M E R A SOCIAL SNAPS! ROGER NIGHTINGALE: Here’s a picture we took of a replacement gas boiler in a school after being asked to locate the mains connection for the original gas boiler. You can see how the plumber and ourselves had to cut out the wall to expose the connection plate, which was fully cemented in…

BASSI ELECTRICAL: This was found at a domestic property, so we called the DNO immediately to help us make it safe.

IMRAN KOLA: I was called out for an electrical fault where an extension wire was the problem. After I opened the plug, to my surprise there was a slug living in it!

STEVEN DOBSON: Don’t you worry, I’ll make it fit…!

JOHN COOMBS: I bet this is the first time you’ve seen the sealing cap used for an outside socket? Carried out by a bodging builder…

GEORGE ROBERTSON: What??!!!!!
