Editor’s Viewpoint

A simple mat ter of lif e and deat h?

Some significant industry news has arrived over the last few weeks, after it was announced that the DPC (Draft for Public Consultation) was out, allowing electrical professionals to have a say on a proposed ‘emergency’ amendment (Amendment 3) to BS 7671:2018+A2:2022 (see page 11 for full details)

The amendment, which is due to be published over the next few months, follows a bulletin from BEAMA which aimed to clarify the differences between connections for unidirectional and bidirectional RCDs and circuit-breakers.

The key change will involve mandating bi-directional protective devices for all generating sets including solar PV, battery storage systems, and EV charging points with vehicle-to-grid capability – basically any device that will conduct bi-directional current flow Seemingly, it will create a tighter set of parameters and definition around prosumers, and the appropriate types of protection they require.

Of course, it only feels like yesterday that Amendment 2 was published, so it’s natural to hear some early scepticism from the front line of the industry around whether what is essentially a minor amendment is necessary and, if so, why it wasn’t identified and incorporated as part of Amendment 2

The reality is that it would be crazy to have a set of regulations that govern working practices within an industry that are only modernised and updated once every decade, so the need to have flexibility with each Edition that arrives is crucial to ensure that they’re aligned with current trends and demands

On the surface, the latest Amendment, although small, could have potentially life-saving consequences, so its incorporation is essential for that reason.

There must, however, be some significant concerns surrounding the number of installations that are currently in existence that have incorporated the incorrect type of protection to this point. If we’re to believe that safety is the sole reason for the proposed update, the undertaking required to revisit previous, potentially unsafe installations, and make them good will be vast It’s also another timely reminder of the rapid speed at which this industry changes, and just shows that what would have previously been classed as a simple installation may now require a much broader knowledge and understanding of how and why protective devices operate

Joining the renewables revolution

While we’re on the subject of modern technologies and installations, this month’s edition features a full and comprehensive special feature section dedicated to the opportunities in, and best practice behind, EV chargepoint installations and other renewables solutions such as solar PV and battery storage systems (starts on page 50)

There’s also the chance to earn another CPD credit towards your annual professional record through our sixth accredited ‘CPD Zone’ section of the year (starts on page 25). In there you’ll find a brand new regular guide from the team at Electrical Safety First with advice and tips for correctly carrying out safe isolation when on-site (see page 41)

Have a good month and enjoy the issue,

Richard B o wler

Electrical industry urged to have its say on Amendment 3

The Institution of Engineering and Technology (IET) and BSI are calling on the electrical industry to have its say on an amendment to BS 7671:2018+A2:2022, which is currently out for DPC (Draft for Public Consultation).

Clarifying the differences

The amendment follows a bulletin from BEAMA which aimed to clarify the differences between connections for unidirectional and bidirectional RCDs and circuit-breakers.

The amendment is due to be published in the summer of this year, where it will be free to view on both the IET’s and BSI’s websites

IET’s Mark Coles, Head of Technical Regulations, said: “When issues arise, it’s important that standards take on the necessary changes as quickly as possible

Collingwood launches lighting energy audit

Collingwood Lighting has launched its lighting energy survey ready for the school summer refurbishment programme ahead of the new academic year.

Andrew Fairhurst, Sales Director, says: “Having a modern LED lighting scheme with control will significantly reduce a school’s running costs, particularly as many still have fluorescent lighting They can use 82% less energy than an old lighting system such as this

“School lighting is important to promote good learning, wellbeing and safety There are a number of different environments in a

school and each area will need to consider illuminance, the correlated colour temperature and control. Safety is also vital for both indoor emergency lighting (in case people need to evacuate the building) and outdoors for security as the light fades.”

The assessment involves the company’s lighting engineers and design team working with the contractor to understand the school’s lighting needs. They will recommend the right luminaires and control along with smarter working practices to provide the best light and help keep the costs down

Darren Casey, Head of Product Development at Aurora Lighting, and most recently Seren, talks to us about how this new EV charger fits perfectly into Aurora’s product portfolio, plus the array of new lighting products the brand has recently launched.

THE MAGNIFICENT SEREN!

QTell us some more about the launch of Seren…

Leveraging over 20 years of electrical expertise, Aurora Lighting UK has created a versatile and installer-friendly EV charger that seamlessly integrates dynamic lighting features

Launched at the end of 2023, we’re incredibly proud of what we’ve achieved The product not only looks fantastic, but it has been designed to include all the installation features and high quality that

electricians expect from the Aurora brand

QHow do you see Seren fitting within the current Aurora product offering?

Aurora has been at the forefront of residential lighting for over 20 years, so Seren EV is the perfect product to complement this

To future-proof residential properties the government recently introduced a new regulation that stipulates all new build homes must be built with 1 x EV

charger per available parking space, so it made perfect sense to us We’re already supplying newly built homes with LED lighting, so why not offer an EV charger as well?

QWhat were some of the important features you wanted to include when designing Seren?

Firstly, just like our lighting, we wanted it to be contractor-friendly, so we spent a lot of time designing specific installation

Installer Credit: JJB Electrical Ltd

features to ensure the process was straightforward Additionally, we couldn’t forget about the end-user who would be using the product every day

Seren is a smart EV charger with a bespoke App, meaning it complies with all UK regulations. The App was also designed and tested by our team in the UK who have made sure that we don’t just offer a high level of control for those who would like it, but also an easy user experience for those who want more basic control

QWhat

makes Seren stand out from other EV chargers?

Seren's standout feature is the dynamic lighting bar capabilities, which we were keen to include as a nod towards our Aurora heritage The RGB lighting feature not only enhances the aesthetic appeal of the charger but also offers valuable user guidance during the charging experience The RGB lighting can be controlled via the App, so end users can select the colours that suit them, or it can be switched off completely if it's not wanted

The lighting element provides a very useful backlight when trying to plug in your car during those dark British winter mornings and nights To complement the dynamic lighting, Seren also has a choice of different colour covers, offering the end user the opportunity to personalise the look of their charger.

QDo

you have any future plans for the Seren brand?

Yes, lots! As a relatively new brand, we’ve still got lots of avenues to explore with Seren The range currently consists of a 7 4 kW charger, but we also know there is a demand for a larger 22 kW version, so this is on our radar for future development. We’re also exploring additional accessories we could offer, plus the introduction of a service that will allow homeowners and small businesses to customise their chargers even further, so watch this space!

QWhat

else has been going on at Aurora?

Well, it's been a very busy few months at

the company As well as launching Seren, which was a brand-new product development process for the team, we’ve also expanded our lighting portfolio In order to support more commercial projects, we’ve added a host of products that are suitable for retail, education and industrial environments

We’ve also launched a brand-new architectural range, Europole, which aims to service the higher-end residential and hospitality sectors, with a range of indoor modular downlights plus a range of attractive outdoor garden lights

Finally, we reintroduced the popular entry-level product offering, Enlite, which is able to serve the price-conscious market

We’re also really proud to offer a leading three-year on-site warranty across a number of our commercial fixtures, which again is testament to the quality of Aurora’s products

QWhere can interested parties get their hands on Seren?

Seren is available from electrical wholesalers nationwide. We’ve recently launched a range of in-branch POS units, so look out for these at your local trade counter

ASK OVIA® OVVIA A

The column where you get to put your lighting questions to the head of the Ovia lighting business, Mike Collins, and his team of technical experts.

QCAN YOU PROVIDE SOME DETAILS ON THE TM66 SCHEME WHICH SEEMS TO BE GATHERING MOMENTUM?

The TM66 Assured Product Verification Scheme is an innovative initiative developed and fulfilled by the Lighting Industr y Association (LIA) and endorsed by CIBSE (Char tered Institution of Building Ser vices Engineers) Its aim is to advance circular economy practices within the lighting industr y TM66: 2021 Creating a circular economy in the lighting industr y, published by CIBSE ‘ sets out what designing and manufacturing to comply with circular economy principles entails, and includes a checklist, a method of assessing a product’s circular economy perfor mance, and real-wor ld examples of good practice ’

The circular economy is a model of production and consumption which places the emphasis on, ‘ sharing, leasing, reusing, repairing, refurbishing and recycling existing materials and products for as long as possible’ The aim is to significantly reduce waste TM66 provides practical guidance to all elements of the lighting industr y, including manufacturers, specifiers, wholesalers, designers and installers in how they might better take account of all the factors which impact upon the use, re-use and re-make of lighting products. At Ovia we’re working towards making sure all our Inceptor luminaires meet the requirements of TM66, and almost the entire Inceptor range has now been tested and scored ver y well on the TM66 Circularity Repor t Products meeting the requirements of the TM66 scheme include the Inceptor Murus LED wall pack with CTA switch and the recently launched Inceptor Milli dimmable, fixed, fire-rated downlight Testing involves the gathering of thorough evidence to suppor t the specifications of the product range The LIA verifies the TM66 results to ensure they have a consistent and accurate rating.

What can I do to ensure I’m not taken advantage of by unscrupulous training providers?

TESP is regularly contacted by people who believed they were training to become a qualified electrician, but sadly it emerges not to be the case

Unscrupulous training providers are offering packages that look attractive to the untrained eye but leave learners paying thousands of pounds for qualifications which are not needed for qualified electrician status and don’t give them the full range of skills needed

If you have friends or colleagues looking to become qualified but don’t know where to start, please share this advice with them

Check what’s included in any packages of courses

very carefully – often they contain courses that are not essential or suitable for new entrants and are not required for an ECS card application Avoid terms like ‘Professional Electrician’ or ‘Full Scope Electrician’, as most of these contain a mix of knowledge qualifications and other courses that are best taken only once you’ve qualified

Work-based training is essential The classroom-based qualifications you’ll gain at a college or other training provider can be a good foundation, but on their own, they do not mean you’re a qualified electrician You cannot qualify without working in the industry

Avoid hard sells. Most providers want to do the right thing and will happily answer questions Be wary if you’re being pressurised to commit to anything without having time to properly reflect or check out any claims, especially if you’re being asked to enter into a financial agreement Reputable providers will have detailed information on their websites, including prices.

As importantly, check out the Rogue Trainers website for our full advice in this area and for details on recognised training routes

NICK JAMES: A FRIEND OF MINE HAS A LANDLORD WHO TOLD HIS MATE TO COME ROUND AND FIX A FAULTY FAN. THIS IS THE RESULT

The number of occasions when unqualified or incompetent people dabble with electrical installation never fails to amaze our industr y. This type of quick fix can result in a serious injur y or worse.

Whatever the reason for the fault on the extract fan, a proper investigation by a ‘skilled person’ was required to determine the issue and to find a suitable solution in accordance with the requirements of BS 7671.

The installation of a temporar y connection such as the twin and ear th floating from the light is not only unprofessional, it is highly dangerous The single insulated conductors are exposed at the light fitting and the extractor fan and the cpc has not been utilised. The cable can be pulled by someone using the facilities, causing the cable to become damaged or loose. Due to the incorrect cable installation, water can penetrate into the top of the extract fan

This is an area where immediate action would be required to remove the danger Although this would normally be a classification code C2, which is still an unsatisfactor y outcome of the EICR, the consequences of any fault occurring could result in serious injur y or a fatality

WHEN IS IT NECESSARY TO USE FUSED TEST LEADS?

Most electricians might assume that the use of fuse-protected leads is unnecessary when carrying out ‘dead’ testing on circuits proven to be de-energised by a recognised safe isolation procedure. Equally, many might think that such leads are always required when testing energised circuits or equipment. This article from the experts at NICEIC discusses the issues that will influence the decision as to whether or not fused leads need to be employed when using electrical test instruments.

The general safety requirements for electrical test instruments are given in the BS EN IEC 61010 series of standards (Safety requirements for electrical equipment for measurement, control, and laboratory use), with the specific requirements for hand-held and hand-manipulated probe assemblies for electrical test and measurement covered by BS EN IEC 61010-031 Conformity with the relevant parts of this multi-part standard satisfies the product certification requirements of the Low Voltage Directive and the corresponding UK Electrical Equipment (Safety) Regulations 2016

More specific requirements for electrical test instruments are given in the relevant parts of the BS EN 61557 and BS EN IEC 61557 series (Electrical safety in low voltage distribution systems up to 1,000 V AC and 1,500 V DC Equipment for testing, measuring or monitoring of protective measures). Neither of these series of standards

specifically requires the use of fused test leads for a particular application

Testing instruments and leads

If an instrument for testing continuity, insulation resistance, loop impedance, earth electrode resistance or any combination of these conforms to BS EN IEC 61010 or BS EN 61557 / BS EN IEC 61557, it should not be necessary to use fused leads since safety is intrinsic within the design of the instrument when used in conjunction with the leads supplied with the instrument

It should be noted, however, that such instruments do not protect against faults occurring between a single test lead and earth when the test probe is connected to an energised circuit, for example if a test lead were to be trapped in an electrical cabinet door

In the case of those tests that are intended to be carried out with the installation de-energised, there should be no risk of electric shock if the circuit or equipment under test has been isolated using an appropriate safe

“It should be noted, however, that such instruments do not protect against faults occuring between a single test lead and earth when the test probe is connected to an energised circuit...”

isolation procedure1

The Health and Safety Executive publication Electrical test equipment for use on low voltage electrical systems (GS38) gives guidance on the safety requirements for the design of test probes and leads for use with test instruments, test lamps and indicators used to detect the presence (or absence) of voltage Although not specifically intended, this guidance is often applied to leads used with other test instruments.

While the leads provided with a test instrument meeting the requirements of the relevant parts of BS EN IEC 610101 or BS EN 61557 / BS EN IEC 61557 should be adequate for the intended use of the instrument, this might not be the case for an instrument that does not conform to those standards In such cases, the use

“In the case of a test to establish the presence or absence of voltage, the use of a proprietary test lamp or 2-pole voltage detector suitable for the working voltage is preferred (paragraph 19 of GS38 refers).”

of fused leads is recommended In the case of a multimeter, an incorrect range setting could be selected inadvertently, allowing an excessive current to pass through the instrument and leads. It is for this reason that GS38 recommends (in paragraph 21) that fused leads should be used with such test instruments.

It should be noted, however, that merely using fused leads with an otherwise unsuitable test instrument will not necessarily make it safe to use

In the case of a test to establish the presence or absence of voltage, the use of a proprietary test lamp or 2-pole voltage detector suitable for the working voltage is preferred (paragraph 19 of GS38 refers)

It is essential that the leads for use with any type of test instrument that are intended to be applied to live terminals at low voltage are inspected prior to each use to confirm that they remain in a satisfactory condition.

Regardless of whether fused or unfused leads are used, the length of exposed tip on the test probes should be kept as short as possible to minimise the possibility of arcing, flashover or electric shock occurring.

GS38 recommends that probes are insulated to leave no more than 4 mm and, where practicable, only 2 mm or less of exposed tip Alternatively spring-loaded, retracting shields may be used (paragraph 9 refers)

Where there is any doubt as to whether the presence of fuses and/or

“Where there is any doubt as to whether the presence of fuses and/or resistances in fused lead sets will adversely affect the functionality or safety of the test instrument the advice of the manufacturer should be sought.”

resistances in fused lead sets will adversely affect the functionality or safety of the test instrument the advice of the manufacturer should be sought F

Summary

Where a multi-functional test instrument is used for verification, conforming to BS EN IEC 61010 or BS EN 61557 / BS EN IEC 61557, it is not usually necessary to use fused leads since safety is intrinsic within the design of the instrument and when used with the test leads supplied with the instrument

However, such instruments do not provide protection against faults occurring between a single test lead and earth when testing an energised circuit W h e r e a t e s t i n g i n s t r u m e n t d

HOW DO PRODUCT CIRCULARITY RATINGS WORK?

If aliens were to bend their ears towards Earth and hone in on the lighting industry (stick with us for a moment on this!), the word ‘circularity’ and its many variations would be picked up fast

“The closed-loop system”, “exchangeability”, “cradle-to-cradle products”, “modular design” – all these commonly used phrases point towards the same sustainable strategy of circularity

The aliens will think this is great news –humans don’t want to destroy the planet! – and, in many significant ways, it is. We’re all speaking the same language of sustainability; it’s front of mind across the lighting industry; we’re a community that shares common values But there’s been something fundamentally lacking from much of this discussion – verification

That’s why the TM66 Assured Product Verification Scheme was developed by the Chartered Institution of Building

Are you asking manufacturers for product circularity ratings? The team at ROBUS explain more about why this is such an important consideration for lighting installers.

Services Engineers (CIBSE) and the Lighting Industry Association (LIA)

How do we identify, implement, and verify circularity?

In October 2021, CIBSE released the Technical Memorandum 66, or TM66 as it has come to be called

This document serves as an in-depth guide aimed at helping specifiers and manufacturers in the lighting sector comprehend and implement the principles of the circular economy

It has four key objectives:

l Promoting sustainable design

l Ensuring material traceability

l Encouraging repair and reuse

l Enabling responsible recycling

Guidance is great, but verification is what sets the standard and that’s what the TM66 Assured Product Verification Scheme is all about.

This scheme adds an additional layer

of credibility and verification to the already comprehensive TM66 toolkit

Significantly, it introduces a new metric: the TM66 circularity rating.

You can ask manufacturers for circularity ratings Through engagement with the TM66 Assured Product Verification Scheme, lighting manufacturers can obtain independent verification of their circularity claims This validation procedure ensures that the ratings offered by manufacturers for their lighting fixtures are accurate, unbiased, and standardised This means you can now compare products from different manufacturers on a like-for-like basis

How does TM66 Assured certification work?

Manufacturers wishing to submit products for certification are required to provide product details in specified formats One such format is the Circular Economy Assessment Method (CEAM), which assesses the circular economy qualifications of lighting products across the supply chain

In practice, the assessment is broken down into parts such as product design, manufacturing, materials, and ecosystem and, for each part, there are specific questions, examples, and evidence required

to inform the overall scoring system

Required documents for submitting to TM66 Assured are:

l Completed CEAM, consisting of 72 questions,

l Supporting evidence to validate information provided,

l All product instructions and product packaging,

l The complete product.

It helps to get guidance from the experts, which is why comprehensive training on conducting TM66 Assured assessments is available through the LIA

TM66 Assured is voluntary, not mandatory

Indeed, TM66 is not mandatory which can sometimes prevent substantial uptake However, many manufacturers are championing this assessment model. ROBUS recently submitted two products for verification – the GOLF surface fitting and SELEST floodlight

Why

these products?

SELEST meets sustainable design standards because it’s designed for longevity, with a high impact rating, a self-regulating valve to prevent moisture condensation and an exceptionally high efficacy of 123Lm/W – 162Lm/W

GOLF has a modular design, which refers to a product design strategy that involves creating a complete product by assembling smaller, independent components. This approach promotes recycling and decreases landfill waste by making it easier to disassemble and reuse parts

The results

Both GOLF and SELEST achieved a strong rating of 1 8 which is defined as showing definite/substantial progress towards circularity. Beyond the rating, the TM66 assessment process provides practical insights for implementing circularity into product development ROBUS has incorporated these learnings into its new product development processes

Keep an eye out for TM66 Assured logos

TM66 Assured certification is valid for three years and can be showcased in various forms, such as being listed in the LIA database Additionally, the LIA is distributing logos that vendors can display on their websites and attach to their products as a symbol of approval.

So, as you navigate the lighting industry's evolving landscape, keep an eye out for these logos they're a beacon of trust and a testament to a commitment towards sustainable practices! BROWSE THE 2024 ROBUS

INTERSTITIAL CONDENSATION

BS 7671 and Building Regulations

The sealing of wiring systems is detailed in Regulation 527 2 1, which specifies the requirements for wiring systems that pass through building construction, such as floors, walls, roofs, ceilings, partitions and cavity barriers

Although this regulation is located in a section that is concerned with minimising the spread of fire, it is detailed further in Regulation 527 2 4, which discusses resisting external influences, such as water and moisture

In Appendix 2, references are provided to the Statutory Regulations, particularly bullet (ii) Buildings, which lists the Building Regulations in England, Wales, Scotland and Northern Ireland Building Regulations have documents and handbooks to further explain the requirements:

l Approved Document C – England 2004, including 2010 and 2013 amendments

l Approved Document C – Wales 2004, including 2010 and 2017 amendments

l Technical Handbook – Scotland June 2023 Edition

l Technical Booklet C – Northern Ireland 2012

These documents are sometimes overlooked by electricians when undertaking installations in domestic properties and you may be caught out by your astute local building control officer who may bring the relevant statutory documentation to your notice

Approved Document C has Item 6.12 which states:

To avoid excessive moisture transfer to roof voids, gaps and penetrations for pipes and electrical wiring should be filled and sealed; this is particularly important in areas of high humidity, e g , bathrooms, shower rooms and kitchens. An effective draught seal should be

provided to loft hatches to reduce inflow of warm air and moisture

l Materials are of a suitable nature and quality in relation to the purposes and conditions of their use

l Workmanship is such that, where relevant, materials are adequately mixed or prepared and applied, used or fixed so as to perform adequately the functions for which they are intended

The Technical Handbook states in 3 15 5:

A floor, wall, roof or other building element should minimise the risk of interstitial condensation in any part of a dwelling that it could damage Walls, roofs and floors should be assessed and/or constructed in accordance with Section 8 and Annex D of BS 5250: 2002.

Although it isn’t as detailed as the Technical Handbook, the Technical Booklet C states in 8 2:

A dwelling should meet the requirement to avoid any harmful effects caused by interstitial condensation if it is designed and constructed in accordance with BS 5250

It is the Building Regulations that provide information regarding the building materials and workmanship required to satisfy both conditions:

If downlights are installed in bathrooms, shower rooms, or other areas of high humidity, an open backed downlight, even if there is no living accommodation above, or even a fire-rated downlight, would not be the first choice, see Fig 1.

In areas of high moisture content, electricians and specifiers should consider a moisture resistant downlight. An IP65 rated fitting with an adequate intumescent seal would be adequate, see Fig 2

This applies even if the ceiling below which they are installed is outside of zones 1 and 2 and is at a height exceeding 2.25 metres in locations containing a bath or a shower

The light fittings that meet these requirements are widely available from a range of suppliers

IN THIS REGULAR COLUMN, DR. TOM BROOKES, MD AT ZZEUS TRAINING AND CHAIRMAN OF THE FSA, ANSWERS YOUR QUESTIONS RELATED TO FIRE SAFETY. IN THIS MONTH’S EDITION HE LOOKS AT COMPLIANCE OF FIRE SAFETY SYSTEMS IF FIRE ALARM INDICATOR DEVICES DON’T MEET THE REQUIRED STANDARDS.

If VAD and VID fire alarm indicator devices do not meet the standards established by EN 54-23, is the system compliant?

There isn’t a simple answer to this question However, in extreme cases, it may not just be non-compliant, it may also be illegal

Since January 2014, Visual Alarm Devices (VADs) have been mandated to adhere to the standards outlined in EN 54-23. These adjustments by BSI were prompted by the UK Equality Act of 2010, aimed at legally safeguarding individuals from discrimination in the workplace These regulatory updates have generated uncertainty regarding the use of combined sounder beacon devices, which are required to meet these standards for the beacon component

Ensuring effective emergency alert systems for individuals with hearing impairments is paramount in any safety system With millions of individuals in the UK facing challenges related to hearing loss, reliance solely on audible alarms becomes inadequate To address this, integrating visual alarm systems becomes imperative

The first step is to consult with the client and check their fire risk assessment The client or their assessor may have good reasons for having EN 54-23 compliant VADs that you may not have considered – there could be many hearing impaired people in the building, for example.

Viewing this document is key for anyone designing a fire alarm system, as putting less safety equipment in the building than the fire risk assessment states could result in you having to explain why you went against the assessment in a court of law, should there be a problem at a later date

A VAD serves as a fundamental component in emergency signalling, providing clear visual cues during critical situations to facilitate prompt evacuation Versatile in application, VADs can be installed indoors or outdoors, mounted on walls or ceilings, and utilised either independently or as part of a larger alarm network

VADs play a pivotal role in environments characterised by high ambient noise levels, such as industrial settings, or where individuals employ hearing protection devices Moreover, they significantly enhance accessibility for those with hearing impairments, ensuring inclusivity across public spaces, offices, educational institutions, and toilet and bathroom facilities. These must comply with BS EN 54-23

In contrast, Visual Indicating Devices (VIDs) serve a supplementary function within alarm systems VIDs should be an addition to existing fire alarm devices but must not serve as standalone systems due to their inability to facilitate evacuation procedures Common applications include exterior installation to aid Fire & Rescue Services, providing coded visual signals for staff, or serving

as remote indicators to pinpoint emergency locations

Where I see people most commonly getting this wrong is within disabled toilets and bathrooms – if there is a need for a visual indicator in a disabled facility it needs to be a EN 54-23 VAD, as a standard beacon would not meet the client’s obligation under the UK Equalities Act 2010

Consequently, adherence to EN54-23 criteria mandates the installation of VADs to cater to individuals with hearing impairments effectively However, in certain scenarios where EN 54-23 compliance is not obligatory, such as those identified during risk assessments, the utilisation of VIDs might be considered

So, in simple terms, if the visual alarm device is likely to be the primary means of indication it needs to comply with EN 54-23, but if the visual alarm is for secondary purposes it may be a VID (standard beacon)

VENTIL ATION DESIGN: WHAT YOU NEED TO KNOW

Rhys Jones, National Technical Manager at National Ventilation, explains how ventilation system design can be made simple for electricians who are keen to install MVHR but aren’t sure how to design and specify this technology.

The latest Part F and Part L of the Building Regulations are designed to help the UK deliver Net Zero, including a reduction of almost a third less carbon for new homes

But, as buildings become more airtight, to improve efficiency and help achieve this goal, it’s crucial to consider indoor air quality (IAQ) too

The new Part F is therefore seen as a vital development since it sets out important changes, which will accelerate the move towards low carbon ventilation as an industry standard while improving IAQ For new build residential homes, the new Building Regulations require higher rates of ventilation to protect resident health This means a move to more advanced ventilation solutions, such as mechanical ventilation with heat recovery (MVHR)

With MVHR increasingly the ventilation system of choice for new build projects now is the ideal time for electricians to take advantage of this growth through projects in small housing development plots However, electricians will need to be familiar with the design and specification of technologies such as MVHR

So, what steps do electricians need to take to design and specify a ventilation system?

Design

The first step in designing a ventilation system is to obtain the drawings from the architect or developer. This is needed to specify the correctly sized ventilation unit and the correct type and lengths of ducting, whilst ensuring it complies with Building Regulations

The architect drawings and property details, including room dimensions, are then entered into an airflow calculator This ensures that the ventilation specified can meet the airflow demands

of each room Once the total airflow figure is calculated an MVHR unit can be selected to meet this need to help improve indoor air quality and reduce space heating costs.

It’s vital to specify the correct unit for a property as different MVHR units will offer different configurations It’s also important to design a system that will provide the correct levels of ventilation and will physically work within the structure If the system is designed to ensure the MVHR unit is never working at more than 75% of

its maximum capacity, this will help it work quietly and efficiently

Location

The next step is to decide where best to locate the MVHR unit The loft is an ideal location for the MVHR but in properties with vaulted ceilings an alternative location is needed, such as a utility room or a plant room

Next it’s important to work out where to locate risers and ducting You need to consider the building design and whether the ceilings have voids to run the ducting or alternatively webbed eco joists where the ducting can be run However, if these aren’t an option, electricians can consider other solutions such as running the ducting between floors or within stud walls.

When it comes to MVHR systems electricians can be put off by the arduous and specialist nature of traditional plastic

ductwork but there is now a cost-effective, simple alternative Semi rigid ductwork, such as National Ventilation’s Monsoon Radial ducting, is ideal for smaller developments since it is flexible but robust and is up to 60% quicker and easier to install, with a Stanley knife the only real tool needed to install it.

This type of ducting also ensures fewer mistakes, since even a novice can install it to a high standard, resulting in an airtight installation and improved system performance With a plethora of plenums and accessories this system can overcome over 99% of issues that may occur on-site

Control

The next step to consider is controls. Traditionally MVHR is often boosted on bathroom lighting, however, not every bathroom visit is a shower or a bath and so

systems can boost unnecessarily

An alternative, more efficient control method is an in-duct humidistat fitted in the ducting, which means the boost only triggers when humidity rises An in-duct humidistat also takes less time to install and is more cost-effective since less wiring is needed to install it as electricians only need to wire the humidistat back to the fan since the fan is constantly on, drawing air from the bathroom

Site visit

Once the design is complete it should include detailed calculations, proposed ducting layout, where to put the MVHR unit and risers and how to control the unit. However, although a design may appear correct on paper it’s vital to ensure a design works on-site

Often plans only tell half the story and you can be caught out if things such as steels don’t show up on the original plans The knock-on effect of this can be a need for additional materials that haven’t been considered in the original calculations.

POWER QUALITY & ENERGY EFFICIENCY

UNDERSTANDING TOTAL HARMONIC DISTORTION

Modern world electronic products, appliances and devices generate current harmonics which can affect the operation and efficiency of an installation and the equipment in it

Put simply, harmonics are currents in an electrical system at frequencies that are whole-number multiples of the supply frequency. In other words, if the supply is 50Hz, the harmonics are currents at 100Hz, 150Hz, 200Hz and so on Generally, harmonics are considered up to the 50th order or 2500Hz

is a measure used to indicate the amount of harmonic distortion present in an electrical installation This is a ratio of the sum of all the harmonic currents to the current at the fundamental frequency, and is described by the following equation:

Harmonic currents add to the fundamental (50 Hz) current in cables and equipment and should be considered in the determination of cable sizes according to BS 7671 – Appendix 4 Current carrying capacity and voltage drop for cables, which references THDi THDi needs to be viewed in relation to the current flow and the circuit or installation capacity. A high percentage THDi at low currents may be of little concern, where a lower percentage THDi could be a major problem for a cable or piece of equipment operating near its rated capacity

UNDERSTANDING POWER FACTOR

Electrical equipment, such as motors and

Julian Grant of ChauvinArnoux UK provides a guide to navigating the subject of power quality and energy efficiency.

other inductive loads, require Reactive Power in addition to Real Power to work effectively

Power Factor is the ratio of Real Power (kW) to Apparent Power (kVA). Reactive Power (kVAR) is the vector difference between Real Power and Apparent Power

High Power Factor indicates efficient electrical energy use Low Power Factor and the associated high Reactive Power can cause energy efficiency and

equipment reliability issues, and reduced system capacity

Consider a pint of beer, where the whole glass is Apparent Power, the beer is the Real Power, and the head is the Reactive Power.

A full pint with no head would represent a power factor of 1, or unity power factor, with no Reactive Power In the presence of inductive loads, a Power Factor between 0 95 and 0 98 is generally OK A pint with a nice small head on it!

Poor Power Factor can be improved using Power Factor Correction (PFC) which utilises capacitors to compensate for inductive loads

Automatic PFC equipment can be used where Power Factor varies as different loads and equipment are used in the installation

If an installation has high levels of

harmonic currents caused by equipment such as variable speed motor drives, use of detuned PFC, thyristor switched PFC, or active PFC, may well be required.

UNDERSTANDING PHASE & LOAD BALANCE

A three-phase power system is said to be balanced when the phase voltages have the same amplitude and are separated by a phase angle of 120˚

Load balance is achieved when the phase currents have the same amplitude and are separated by a phase angle of 120˚.

Voltage imbalance describes the situation where the voltage magnitudes, or the phase angle differences between them, or both, are not equal

Voltage imbalances are caused by large differences between the 3 phase

currents, which in turn are caused by the poor distribution of large single phase loads

Having balanced phase voltages is important for industrial installations containing 3 phase motors Unbalanced voltages can cause a phase current imbalance up to 10 times the percentage voltage imbalance

Use separate circuits for large single-phase loads connected as close to the incoming supply as possible to reduce the voltage drop on wiring utilised by other equipment

Ensure that all single-phase loads, large and small, are balanced evenly across all three phases.

You ask: RECENTLY, I’VE BEEN MORE INVOLVED WITH INSTALLING ELECTRIC VEHICLE CHARGE POINTS, AND I’M EXPECTING THAT I WILL SOON START TO BE ASKED TO PROVIDE ROUTINE TESTING FOR THESE. THIS IS ALL PROFITABLE WORK, BUT FILLING IN THE TEST CERTIFICATES BY HAND IS TEDIOUS AND TIME-CONSUMING. IS THERE A WAY TO AUTOMATE THIS PROCESS?

Megger says:

There certainly is – by using Megger CertSuite Installation software This includes two certificates specifically for EV charge points The first is an electrical installation test report, which you would use when certifying a new installation, and the second is an electrical installation condition report which you would use to record the results of routine testing on an existing installation These certificates will cover all of your requirements relating to EV charge points, but CertSuite Installation can do much more; it provides everything needed to produce certificates for all types of domestic and commercial electrical installation When CertSuite Installation is used with a Megger MFT-X1 multifunction installation tester, results are captured directly from the instrument – no manual data entry is needed Results are stored securely in the Cloud or, if no internet connection is available, they’re stored locally for uploading later CertSuite Installation is available as a mobile App for iOS and Android devices, and it’s also compatible with all widely used browsers on laptops and desktops

So, you’ve heard all about the benefits of electrical vehicles for the planet, but how can this new boom in green transport prove to be a positive for you as an electrical contractor? The team at Rolec provides more detail.

JUMP IN FLEET FIRST

When you first think of EVs, your mind might initially jump to homeowners and individuals as being the main driving factor in overall adoption. Although this is a demographic that has really championed the electric vehicle movement, there’s an even bigger industry driving the transition to net zero

Fleet’s ahead

The fleet industry is where the real growth will be seen in this sector In fact,

according to recent data produced by Samsara, ‘‘more than half of fleets operating 150-plus vehicles expect to have a hybrid or fully electric fleet by 2025’’

This growth is being further catapulted by supportive government grants such as the Workplace Charging Scheme for state-funded education institutions and The Infrastructure Grant for staff and fleets, progressive regulations (Part S, for example) and the growing demand for public charging infrastructure to support the EV driver on-the-go

All of this provides you with the

potential for an ever-growing customer stream Increased demand for EVs makes it a reliable source of income now and in the future, with the benefit of offering annual maintenance packages with installations.

There are currently over one million electric vehicles registered in the UK, and this isn't showing any signs of slowing down soon As these numbers continue to rise, charging infrastructure must grow to meet demand, so installers are vital in making it happen

Smaller companies may be hesitant

due to the initial costs, but thanks to organisations like Wattif EV, fully funded, part funded, and subscription solutions are available to businesses that are looking to introduce EV charging but don’t have the upfront capital to implement it

Being aware of these opportunities as an installer means you can offer fully funded and managed EV chargepoints to clients who are unsure about the cost of installing chargepoint infrastructure and the associated chargepoint management requirements.

Of course, there’s also the environmental benefits of becoming an EV chargepoint installer to consider Not only will you be growing your business and championing environmental change as an individual, you’re also making it possible for other businesses to meet their sustainability goals – something that has become increasingly more important over the last decade.

Become a Rolec EV Approved Installation Partner

Daniel Forsberg,

CTEK’s Marketing Manager EVSE,

discusses the increasing need for chargepoint solutions to provide futureproofing capability that will ensure sustainability from EV installations.

BUY WELL, BUY ONCE

EVs are all about sustainability, cutting carbon and clean mobility When powered by electricity from renewable sources, the impact they’re making on our shared road to net zero is substantial and growing.

To make EVs as positive a contributor as possible, the whole ecosystem they exist in must also play its part From how the electricity is generated to reducing wastage in supply equipment and enabling Vehicle to Grid (V2G) bi-directional charging, there are sustainability wins to be had at every turn

When we were designing our newest chargepoint (the CC3), we thought long and hard about how to make it as futureproofed as possible, knowing that doing so would enhance the sustainability of our product and the installations where it is used

We believe all installers and their clients – from homeowners to landlords, destinations to local authorities and chargepoint operators – should have longevity and flexibility in mind when specifying EV charging solutions.

Does the unit they’re going to install have the capabilities needed not just for today’s charging needs but for the opportunities of tomorrow? Is the hardware futureproofed for the next wave of EV charging capabilities? Can it handle the software coming down the track?

Installers will want their clients to have confidence that their new EV charging

installation is going to function as well (or, ideally, better) in three years’ time as it will on the day it is first plugged in So, what should installers and their clients be looking for when considering an investment in chargepoint equipment?

Standards and protocols

To take advantage of the opportunities to supply electricity back to the grid, chargepoints should support the international standard ISO15118 which is a leap forward for EV-to-chargepoint communication Among the advances it enables are:

l Plug & Charge: automated vehicle identification and billing for charging sessions.

l V2G: bi-directional charging for EV drivers to be paid for discharging electricity to the grid at times of peak demand

l Dynamic Charging Mode: introducing a dynamic control mode alongside the existing scheduled mode, allowing for more nuanced control over charging processes

l Security: enhanced data protection closes existing loopholes, protecting user

data and payment information

l Multi-contracts: simplifying the management of multiple e-mobility contracts, allowing users to seamlessly switch between different charging contracts based on location

Meanwhile, chargepoints should also support OCPP (Open Charge Point Protocol) 2.0.1, ensuring smooth interaction with a whole host of current and future third-party hardware and software

OCPP 2 0 1 compliant equipment prevents customers being boxed in and having to rely on the service from, or continued existence of, just one provider They can change their back-end provider for payment and monitoring and expand with additional chargepoints from different manufacturers

The longevity of hardware will also be enhanced by a range of connectivity technology, so you should look for chargepoints that can communicate via ethernet cable and WiFi. Alternatively, 4G communication is useful for remote sites, especially with some older chargepoints that are equipped with 3G now starting to fail

Repairability

UK roadsides and car parks already have too many obsolete and broken chargepoints that are uneconomical to repair or terminally compromised for future use. These tombstones are a sad memorial to wasteful technology that was not futureproofed

So, look for charging equipment that can be easily serviced and, if necessary, repaired Find out if a chargepoint has replaceable standardised components such as the contactor, RCD, fuse, socket or fixed

charging cable Indeed, sockets and cables can experience significant wear and tear in high use environments such as public car parks

Upgrading

Robustness

Installers and their clients should be thinking about current EV charging needs as well as future demand As more multi-car households invest in multiple EVs, home chargepoints with dual outlets will become desirable, so choosing one now is an easy futureproofing win For non-domestic properties which currently have a single phase supply, upgrading to three phase in the future opens up the potential for faster charging for one or more EVs Again, specifying hardware now that can handle three phase supply, as well as single phase, will futureproof the installation, as you can keep existing hardware rather than buying and installing again

Charging points installed in public areas such as car parks should have a minimum IK08 rating for impact protection and an Ingress Protection (IP) rating of IP54 to keep out dust and rain These physical protections complement the digital cybersecurity of encrypted communication and unique passwords

Look for long and extendable warranties, plus in-country support for preand post-installation advice and guidance. Training for installers, which can be free, will ensure smoother installations and trouble-free operation

PICK AND CHOOSE

g g r, offers some tips to help customers choose the right EV chargepoint for their requirements.

Finding the right EV chargepoint that suits the needs of your customers while being easy to install and maintain isn’t always a simple task Despite there being a myriad of chargepoints now available on the market, they all operate slightly differently, which can make choosing the right product an overwhelming consideration

By the end of 2024, we’ll see at least a 20% increase in electric vehicle sales (not

accounting for plug-in hybrids), which is further indication of the growing number of chargepoints and installations required

As such, let’s take a look at the top five pieces of information that installers should be aware of to assist customers in choosing a suitable chargepoint solution:

1. Electrical supply

Charging electric vehicles puts a large load on the supply for a prolonged period of time with no respite. For this reason, the

size and maximum demand on this supply needs to be calculated in order to establish if there is spare capacity and whether some form of load management needs to be used

Additionally, the Distribution Network Officer (DNO) must be notified before or after installation, depending on the type of installation and size of the supply

Easy to achieve with the right equipment, load management requires the correct hardware and App. This can be carried out manually using CT clamps or the services of specialist companies (e g CPOs), who can manage this via the Cloud

2. Installation

It goes without saying that chargepoints have to be located in parking areas for vehicles to connect to them, however there are still a number of things to consider, including wall or post mounting, ducting runs and the ability to easily alter cable for future upgrades

As chargepoints are a smart connected product, consideration must be given to whether the data cable is routed to them directly as this can provide a more stable connection than using Wi-Fi Also, where

load management is used, a RS485 communications cable is often needed, such as in the case of connecting the energy meter with the chargepoint

3. Usage

Electric chargepoints are smart connected devices as required by The Electric Vehicles (Smart Chargepoints) Regulations 2021, requiring an App to operate them To provide an alternative to getting out your phone and using the App to start and stop charging, the Deta e chargepoint has the option of using an RFID card

Whether in a workplace or home setting, chargepoint owners can ask users to pay for electricity usage by setting up accounts through the user App Chargepoints can either be tethered (supplied with a pre-fitted cable) or un-tethered (where a user has to supply their own cable)

The Deta e charge point is supplied untethered but has the ability to lock the

cable into it, effectively converting it to a tethered version if the user requires

Should the cable become damaged, this has the advantage of allowing the user to easily replace it themselves without requiring a contactor. It should be noted, however, that in some UK locations tethered chargepoints are still not permitted

4. Landlords

Where a user needs to pay for electricity used, such as a workplace setting, it is possible for the landlord or business to set up individual user accounts and manage this themselves. This effectively makes them a CPO (Charge Point Operator)

An alternative to this is to use the services of companies who not only manage the chargepoints by monitoring their usage, but also ensure they are maintained and operating effectively These third-party companies will also

manage the account and billing for users based on the energy they have used

5. Grants

Building a network of smart home EV chargepoints is high on the agenda for the UK government. To support this growing industry, the Office of Zero Emission Vehicles (OZEV) offers grants to residential users, directly benefitting rented and rental properties

Not only are tenants who are renting a flat able to apply for EV charging grants, so are landlords for flats and houses with off-street parking, making it an ideal time for landlords to invest in smart EV chargepoints like the Deta.e eDock or eVoom, and futureproof their investment properties

Have you and your customers considered turning to solar to power electric vehicles?

Here we discover some of the compelling reasons to adopt dual energy sources.

IN THE SUN THE DUAL

Homeowners who are environmentally conscious and seeking energy independence now have more options than ever to use renewable energy at home

Solar panels are the most frequently used way to get renewable energy into the home, and we’re now seeing renewable energy used for more than just powering appliances and switching on lights.

When looking to start maximising the potential of renewable energy sources with dual energy sources, electric vehicle charging is a great place to start and offers a solution that is perfect for optimal energy efficiency

Electrical vehicle specialist evec, recently launched its EV home chargers (VEC01 & VEC03) with the addition of standard solar integration. These upgraded chargers can harness the sun's

power, ma ever and m access to solar panels

Switching to EVs already reduces the lifetime emissions of a car by three times, but why should electrical installers advocate for solar-powered EV charging and dual fuel use in the home?

Eco-friendly advantage

By tapping into solar energy, EV owners further reduce their carbon footprint The environmental impact is significantly reduced when combined with EVs’ inherently lower emissions

Cost savings

Implementing multiple energy systems can help homeowners reduce their reliance on fossil fuels and high electricity bills. Selling excess energy back to the grid can also generate income

Flexible charging

Solar-powered charging allows EV owners to adapt charging to schedule and tariff preferences

With solar integration, you can charge either with sunlight during the day or through the use of a cheaper tariff overnight (or both). The evec App, for example, also has a specific “eco (solar only) mode,” which allows users to charge using solar power only

Various grants are also available across the UK, and a 0% VAT option can offset the cost of the initial installation of solar panels, making their integration even more appealing for home and EV owners

Solar panel functionality

Photovoltaic (PV) cells absorb sunlight, converting DC energy to AC through a solar inverter This AC power can then be used to support all electric devices

Integration requirements

While any EV charger can connect to solar panels, a PV inverter is essential for converting DC to AC Some EV chargers, like the evec VEC01 & VEC03, already have this integrated technology

Number of panels

The right number of solar panels depends on factors like EV range and energy requirements. According to Octopus Energy, an average solar panel system of 8-12 panels can charge an EV This would give an average of 1 to 4 kWp – enough to charge an average EV in about eight hours

Electrical installers advocating for solar-powered EV charging align with sustainable practices and help meet the evolving needs of eco-conscious clients To get the greatest benefits, home and EV owners should integrate multiple renewable energy systems to provide sustainable and reliable home energy solutions

We catch up with the team at Lewden to find out more about the benefits of utilising EV feeder pillars for both domestic and business purposes.

A PILLAR OF SUPPORT

EV feeder pillars are critical components in the electric vehicle charging infrastructure

Feeder pillars are designed to provide safe and reliable electrical connections for EV charging equipment, essentially providing an outdoor hub that can safely distribute power from one supply source to multiple EV chargepoints

What are the typical features of an EV feeder pillar?

EV feeder pillars are arranged with a device for isolation of the incoming supply source Depending on the electrical arrangement of the building, this may be a switch disconnector, a fuse, or moulded case circuit breaker (MCCB).

EV chargepoints connected to the pillar may require single phase or 3 phase distribution supplied in various current ratings according to the variety of kW EV chargers The pillar houses the circuit protection devices essential for connection to each of these final circuits This would typically provide protection against

overcurrent, residual curre transients, and PEN condu

EV feeder pillars can a metering to monitor powe from the supply network

What do the Building Regulations state regarding the provision of EV chargepoints?

For new residential buildings, Part S of the Building Regulations states that the number of associated car parking spaces that have access to EV chargepoints must be:

1 The total number of associated parking spaces where there are fewer associated parking spaces than there are dwellings, or 2. The number of associated parking spaces that is equal to the total number of dwellings within the residential building, where there

more associated parking spaces than the dwelling

Where a building undergoes material change of use and one or more dwellings with associated parking result, at least one associated parking space for the use of each dwelling must have access to an EV

charging point

Where a residential building undergoing major renovation work will have more than 10 associated parking spaces after completion of the renovation, at least one parking space for the use of each dwelling must have access to an EV charging point

Where a new building, which is not a residential or mixed-use building, has more than 10 parking spaces, at least one parking space must have access to an EV charging point

How can EV feeder pillars aid compliance to the Building Regulations?

Strategically placed EV feeder pillars allow a number of EV charging points to be radially connected from one or more central hubs, allowing easy coverage to larger parking areas with EV charging points for business They create a central point of interface for system protection, metering and isolation

How are EV feeder pillars constructed?

EV feeder pillars can be constructed from a range of different materials and finishes, depending upon their environment and specific applications

Mild steel cabinet construction is suitable for sheltered inland installations situated more than 20 miles from the coast, whereas stainless steel construction would suit externally exposed, polluted, or coastal atmospheres where salt corrosion is a factor

THE BOX OF TRICKS

From concept to design, we discover more about the brainchild and journey behind the launch of the new Enkin Solar Box.

With 60 years of combined electrical expertise, the Enkin design team is dedicated to solving residential and commercial lighting challenges, and this includes re-imagining an overlooked and unreliable aspect in lighting – portable solar panels.

With poor battery operation, unreliable charging, and ineffective waterproofing, some solar panels can have a less than stellar reputation, particularly when it comes to outdoor lighting

The problem

Enkin began to address the problems associated with outdoor lighting as a whole by recognising the benefits that outdoor lighting provides and how these practical aspects are negatively affected

Installing exterior lighting to properties adds functional and aesthetic benefits, including improved visibility, safety and security, highlighting architectural

structures, extending the use of the outdoor spaces in darker evenings, as well as improving visual and atmospheric ambience Combining these elements can be particularly challenging when faced with constraints such as wiring access, listed building regulations, power consumption, and lack of portability.

Next, the team collected data on the issues surrounding the construction of poorly manufactured solar panels and began conceptualising a portable solar box that not only provides solutions for outdoor lighting, but overcomes the technical problems associated with some solar panels on the market today

The concept

With field research and data collection completed, the design team was able to begin working on innovative solutions to the multitude of problems that affect not only solar panels, but outdoor lighting as a whole It was important for the final design to include features that would prolong the longevity of the solar panel itself, as well as ensure reliability and convenience for the user. Portability is a main design feature for the Enkin Solar Box, which is housed in an IP66 rated casing constructed from high quality plastic, measuring 500 mm (W) x 350 mm (L) x 100 mm (H) that can be relocated and

set up with ease (sizing is subject to change and may vary)

The solar panel itself measures 465 mm (W) x 300 mm (H) This fully removable panel comes with the use of a 10-metre cable and can also be angled within the housing by using the adjustable support legs situated beneath the panel.

Housed inside the protective casing of the Solar Box is a power off/on button, with optional timer modes as standard, with up to eight-hour timed operation and 5 V, 12 V, and 24 V lighting connectors

The option for additional PIR motion detectors can be attached to activate lights, allowing the user to place the Solar Box in a high traffic or dimly lit area to act as a security light or motion activated guide light.

Further developments

It’s worth noting that in conjunction with the Solar Box having Zigbee compatible smart mode functionality, the team is working to improve user convenience with an Enkin ‘smart’ App that will play a crucial role in all Enkin products in the future

This App, which is currently in development, will enable the user to view real-time charging, battery percentage, estimated charge time, estimated battery run time, and weather forecast, as well as allowing practical remote functions such as powering on/off and dimming

GETTING ON THE RIGHT COURSE

Pete (Monty) Monfort, Director of Arena Training Centre and Monty Electrics, shines a spotlight on the BPEC Solar Voltaic Systems course.

COP28 took place in Dubai in 2023 and saw close to 200 countries battling it out to agree on the wording for a global climate change deal No doubt many readers will, like me, despair at the politicians as they chop and change on their promises and commitments, especially where it relates to the health of the environment

Actions speak louder than words, however, and our industry has the capacity to make a difference at a grass roots level by implementing green technology solutions for homes and businesses

Whilst there are growing numbers of society waking up to environmental issues

and thinking about how their own actions can combat climate change, there are many more who might be convinced to adopt the technology from an entirely

financial viewpoint In particular, the cost of energy and the volatility of energy prices has forced many people to reconsider their options

Either way, the solar industry is starting to see a new lease of life after it was all but killed off with the expiration of the ‘Feed In’ tariff scheme

So how can you benefit from this refresh of the PV industry and why might you consider undertaking training such as the BPEC Solar Voltaic Systems course when you’re already qualified to install and commission electrical systems?

The BPEC Course addresses many of the issues outlined in the following paragraphs and will help prepare you for an area of electrical design and installation that has many pitfalls for the unprepared

Competence

Whilst solar differs little from any other electrical work in that you’re required to design, install and inspect, according to BS 7671 Photovoltaic Installations are classed as a special location. In fact, the technology has a full Code of Practice – Grid

Connected Solar Photo Voltaic Systems –written by the IET (ISBN 1839537515) and installers will need to familiarise themselves with regulations relating to circuit protection, connection methods, earthing, bonding, system design, and circuit protection to name but a few

Health & Safety

Installation involves working at height and some electricians will need training to understand the risks of working on scaffolding and lifting methods for carrying equipment on to roof spaces

PV systems also utilise DC current and there are risks that some electricians will not be familiar with the increased risk of arcing and differences in the way in which

circuits are switched and isolated Work is also carried out on live cables since PV panels are always generating when exposed to any source of light

Design

There are lots of factors to consider when designing an effective system Roof elevation, direction and location will impact on potential generation, while shading issues can greatly impact on the efficiency and may merit different systems or indeed may be entirely unsuitable.

Energy consumption patterns and loads will need to be considered and knowledge of different manufacturer requirements PV systems also need equipment such as invertors to be located in suitable places and there are different requirements for volt drop, when compared to the norm

Rules & Regulations

Installers must adhere to the law, rules and regulations relating to solar PV installations You should be aware that installation of new electrical circuits requires notification to building control In most cases planning permission isn’t required but there are exceptions

Additionally, generator systems must comply with regulations relating to their connection to local supply systems and you may need to connect and notify (G98) or seek approval for larger systems (G99)

Certification by the Microgeneration Certification Scheme (MCS) can benefit installers since it provides customers with reassurance that you’re competent and will install quality equipment and that they won’t lose out on any financial incentive schemes

Structural knowledge

Installation of PV equipment can add significant loads to roof systems While the panels themselves are not particularly heavy they can act like sails in the wind and, as such, structures must be assessed for their strength.

You may choose to learn how to carry out your own structural surveys or you may wish to work alongside a registered engineer to assist you

Likewise, the panels bolt to the roof and this involves lifting, moving and repairing tiles This is another area that you may choose to become competent in or work alongside a roofing specialist.

Inspection & Testing

Installers will already be familiar with most of the techniques used for testing electrical circuits but solar systems remain live and thus the testing procedure must take account of the risks of working on live circuits whilst testing Specialist testing equipment makes this easier and safer Inspection of installed circuits is arguably even more important for DC systems due to the increased risk of arcing.

Solar is here to stay

In summary, solar PV systems are likely here to stay Even if you’re not interested in becoming an installer, the likelihood is you will come across them in your everyday work moving forwards, so knowledge is key to ensuring your safety

The BPEC Solar PV course was developed with the aim of providing electricians with the skills and knowledge required to install small scale PV systems

The course has been structured to meet the requirements of the National Occupational Standards and is recognised as a demonstration of competence for the Microgeneration Certification Scheme (MCS)

How can the electrical trade tap into the growing solar revolution? Brinley Buckley-Roberts, Head of Marketing at C.K Tools, offers some pointers.

INSTALLING A SOLAR FUTURE

The rise of solar energy is well and truly upon us with more households and businesses installing rooftop solar panels than ever before The potential for growth in this sector is huge, with the UK market size measuring £1 2bn in 2023 (an increase of 35%) with trade organisation Solar Energy UK working to achieve a five-fold increase in the UK’s solar capacity by 2035.

Spiralling energy costs, a recognition of the importance of renewable energy sources and advances in technology (making solar panels more affordable and efficient) have all proved to be a game-changer in recent years, prompting a trajectory towards widespread solar adoption.

The proliferation of solar energy is also a game-changer for the

electrical trade As the demand for solar panels increases, so does the demand for qualified electricians equipped with the right training and tools to complete installations effectively

Tools for the trade

This presents an exciting opportunity for electricians looking to diversify their offering and grow their businesses. But what do installers need to do tap into this growing market? And what tools and

accessories do they need?

C K Tools, as a business that has been at the forefront of premium tools for more than 100 years, has invested heavily in the solar sector to support the electrical trade with the growing demand for solar panels

As with most of our product R&D, we spent time with solar installers to develop tools and kits specific for this job, to ensure clarity, comfort, control and efficiency. As a result, we’ve assembled a quality Solar Installer Kit, tailor-made to provide the core tools required to complete a solar installation in a lightweight, durable and affordable package

The kit also includes the T3671A Ratchet Solar Crimper for safe, secure crimping of MC3/MC4 PV connector types, which is essential for completing a solar job safely, accurately, and to the required legal standards

CHEMISTRY LESSONS

Dave Roberts, UK MD at GivEnergy, explains why LiFePO4 battery chemistry can help allay recent fears surrounding home battery fires.

Consumers are increasingly opting for home batteries as a means of cutting their electricity bills and carbon emissions. Whether as a standalone system or coupled with renewable technology, home battery storage is becoming increasingly practical and affordable

Now, with this rise of home batteries, scrutiny of relevant fire safety measures is also on the rise

Home batteries hit the headlines

Several recent incidents in Australia have put home battery fires under the spotlight.

According to 9News network, solar storage battery fires have been linked to at least 13 cases of property damage in the country This includes the destruction of a house in the state of Victoria In response, the Australian Competition & Consumer Commission (ACCC) has proposed a compulsory recall of the battery models responsible.

Elsewhere, the media has been awash with reports of ‘lithium-ion battery fires’ (sometimes labelled interchangeably as ‘lithium battery fires’) In this respect, the incidents in Australia feel like a continuation of this trend

It’s important to note that these ‘lithium battery fires’ are more often than not connected to smaller devices Think smartphones, laptops, electric scooters, etc. – all of which use lithium-ion batteries.

A report by the UK government’s Department for Business, Energy & Industrial Strategy acknowledges this link It states that “most available fire statistics for lithium-ion batteries are related to smaller portable products”

For home battery storage systems, meanwhile, the same report acknowledges

the lack of specific statistics It states that concern about fire safety is simply based on “the large energy content within (home battery) systems”

With all of this taken into consideration, it’s understandable that members of the public may have concerns about fire safety regarding home batteries. There are valid reasons, however, to feel reassured

Moving towards safer chemistry

Often omitted in media reports on ‘lithium battery fires’ is the fact that ‘lithium-ion’ can refer to several different types of battery chemistry

Two of the main types of li-on battery found on the market include nickel manganese cobalt (NMC) and lithium iron phosphate (LiFePO4)

conditions, environmental friendliness, and high power density

NMC chemistry was used in the solar storage batteries responsible for the aforementioned incidents in Australia. In fact, it’s almost exclusively the cause of ‘lithium battery fires’ in small devices, too

On the other hand, LiFePO4 batteries are proven to be less prone to thermal runaway, reducing the risk of fire Compared to its NMC counterpart, LiFePO4 cell technology boasts exceptional safety, an extended lifespan, enhanced performance in extreme

The good news is that LiFePO4 cell technology is increasingly the choice for home battery storage systems. Globally, the proportion of NMC batteries in electric vehicles, energy storage systems, and consumer electronics was 51% in 2022, compared with 26% for LiFePO4 By 2033, the proportion of NMC batteries is forecast to decline to 43% Meanwhile, the same figure for LiFePO4 batteries is set to rise to 48%, according to research from Fastmarkets

Recent changes to installation guidelines

Recent focus on home battery fire safety in the UK concerns changes to guidelines on loft installations

The British Standards Institute (BSI) recently published PAS 63100: 2024. In section 6 5 5, it states that batteries shall not be installed in “voids, roof spaces, or lofts” Reasons for avoiding installations of home batteries in lofts can include, among other things:

l Poor ventilation and airflow,

l The presence of flammable insulation in older lofts.

Where users tend to install home battery storage depends on their individual circumstances For those installing battery storage units in properties with limited space, the loft space may be the only feasible option

A fire-safe future for home batteries

Given the shift to LiFePO4 in home battery storage, we believe it’s feasible that PAS63100:2024 may alter the guidelines with relation to loft installations This will come as a relief to homeowners who want to invest in home battery storage, but don’t have the necessary space outdoors

In the meantime, it’s the responsibility of those working in the battery storage industry to ensure consistent messaging around fire safety

In part, this involves clarifying the necessary safety measures users of home batteries should take This includes ensuring batteries are professionally installed and fitted in well-ventilated areas, for instance

It also involves getting the message out around the enhanced safety of LiFePO4 batteries Simply put, based on the available numbers here in the UK, battery fire risk (especially home battery fire risk) isn’t something anyone should need to lose sleep over

With over 20,000 UK homes per month installing solar PV, an entirely new market is open to installers who can now offer a truly efficient, value-for-money EV charger where integrated solar charging is already included

Charging vehicles with solar energy

Ingeniously, thanks to the intuitive smartphone App, homeowners can cut their home-based EV charging costs with the Sync EV Wall Charger 2

By utilising surplus solar energy from their existing solar panels – with no modifications to panels required –instead of having any surplus directed back to the grid, homeowners can potentially charge their EVs for free with Sync EV

In addition, with personalised settings such as scheduled charging and optimised cut-off points, allowing users to charge dynamically and maximise cheap rates of electricity, the Sync EV Wall Charger 2 delivers a faster home charge compared to plugging a charging cable directly into a 3-pin socket which gives a very slow charge at a fixed rate – both inconvenient and less cost-effective.

Designed for life

Designed with sleek aesthetics, and no compromise on practicalities, the Sync EV Wall Charger 2 is available in two versions – tethered and untethered – to suit individual needs

The tethered option, which comes with an integral 7.5 m fixed wraparound cable that is fitted with a user-friendly charging gun for attaching to the vehicle, provides a neat, tidy and safe solution And, since the charger uses personalised settings, your customers can rest-assured that they’re completely in control of who uses

their charger – no rogue charges are possible

With a charging capacity of up to 7 4 kW with a standard household single-phase electrical supply, and a 3-phase version available which can deliver up to 22 kW and is ideal for commercial customers, the Sync EV Wall Charger 2 which is controlled via a smartphone, allows users to rent out their charger, for example to neighbours,

providing additional income

Available in a range of eight interchangeable colours options – traffic white, signal grey, sandstone yellow, signal red, jet black, blue grey, deep blue and racing green – customers can co-ordinate their EV tech with their electric vehicle

The EV Wall Charger 2 has a three-year warranty, is CE-approved and stringently tested to ensure complete confidence and peace of mind

It’s O-PEN season with MCB-MCCB boards

O-PEN protection is now available in a range of 200 A, combined MCB-MCCB boards from Proteus Switchgear.

As EV chargers increase in power output standard MCB boards cannot supply these larger chargers The OPMCX board allows fitting 2 x MCCBs as well as MCBs without the need to use a full size MCCB panel board.

All boards have a 200 A, 4 pole, switch disconnector main isolator, and can accommodate two 3 pole MCCBs up to 160 A maximum. The MCB section can be 4, 6 or 8 TP ways up to 63 A depending on the board ordered This section can be fitted with Proteus’ 3 module 4 pole RCBOs and MCBs and 2 pole 1 module RCBOs, as well as the brand’s other MCBs and RCBOs.

PEN protection is fitted, switching 3 phases, neutral and the EVC insulated earth bar, giving total disconnection from the supply in the event of a PEN fault.

The layout of the board has been arranged to assist installation in a feeder pillar with the main switch fitted to the top of the panel, allowing easy cabling from an adjacent service head Outgoing cables are bottom exit for cabling through a trench The width is 600 mm, narrower than a full MCCB board, helping to maximise the space within the feeder pillar Options for surge arrestors and metering are available

This new OPMCX range of combined MCB-MCCB boards is designed to complement typical feeder pillar and service head

ALL PART OF THE PLAN

With every quote adding to your schedule and every new job bringing a new challenge, financial planning often takes a backseat to the day-to-day running of your business. That needs to change, according to James Chillman, UK Country Manager of Fergus.

Mastering the art of business

financial planning is something all tradespeople should be doing: it’s what keeps your electrical contracting business strong and growing

When it comes to financial planning for your business, budgeting is crucial to financial success It’s all about knowing what you need to spend money on right now, predicting upcoming payments and preparing for what might be down the road

Making a budget means carefully calculating what each job will cost, how much you’ll spend on materials and how you’ll pay for your team

Here are four steps towards creating a strong budget and plan:

1. Assess your current financial health

Before you can plan for the future, you need to understand your present Analyse

your income, expenses and cash flow to get a clear picture of your financial status – look at what you know you need to pay out for and take into account anything that might be accruing, such as tax payments

2. Set clear financial goals

Whether it’s expanding your services, investing in new tools, or saving for a rainy day, having specific, measurable, achievable, relevant and time-bound (SMART) goals will keep you focused It’s an approach that eliminates guesswork, sets a clear timeline and makes it easy to track progress and spot missed milestones

3 Create a detailed budget plan

Allocate funds for different aspects of your business This should include direct costs like materials and labour, as well as indirect costs such as marketing and transportation

4. Monitor and adjust regularly

A budget isn’t set in stone Regularly review your budget against actual expenses and adjust as required.

Making a plan should include financial forecasting This lets you make informed decisions about the future of your business

You can do it by using historical data; look at your past financial performance to identify patterns and trends Consider the market conditions and stay informed about the economic climate and how it may affect your business.

Plan for different scenarios and create best-case, worst-case and most-likely financial scenarios to prepare for uncertainty

Job management software can help you do this, especially when you integrate it with an accountancy software package, like Xero

Cash flow

It is an often-used phrase, but “cash flow

is king” for any business. Effective cash flow management means you have enough money on hand to pay bills, purchase materials and invest in growth opportunities

There are three basic ways to make sure cash is flowing regularly into your business

The first is to invoice promptly, so make sure you send out invoices as soon as a job is completed to ensure timely payments The second is to manage outstanding invoices and follow up on late payments. Thirdly, control your costs, expenditures and avoid unnecessary expenses

Maximising your profit margins

Profit planning is about setting targets for your income and creating strategies to achieve them It involves looking at each aspect of your business to identify areas for improvement and increase profitability Here are three ways to do it:

1 Review pricing strategies: Ensure your pricing reflects the value of your services and covers all costs

2. Optimise operations: Speed up processes to reduce wasted time, energy and money

3. Invest wisely: Reinvest profits into areas of your business that will generate the highest returns

Smaller business

If you’re a small trade business, financial management can be particularly challenging However, there are some basic principles to look at Keep personal and business finances separate and don't make things tricky for your accounting Keep things simple by sticking to these boundaries

Use technology like software to automate

financial tasks, manage your day-to-day and provide real-time insights into your business performance Always seek professional advice and don’t hesitate to consult with financial advisors to help with complex financial decisions

When creating your budget, don’t forget to allocate funds to areas that will contribute to long-term growth Whether it’s new equipment, additional staff or professional development, thoughtful investment can set your business apart from the competition.

Here’s a few final things to think about in terms of financial planning:

Evaluate ROI: Consider the return on investment for any potential expenditure

Diversify investments: Don’t put all your eggs in one basket; spread your investments to reduce risk

Plan for retirement: Even if you’re just starting out, think about your long-term future and invest in retirement plans that suit your needs.

Financial risk assessment

Remember to protect your business by managing financial risks Conducting a risk assessment to identify potential threats and develop strategies to mitigate them is a good use of your time

Ensure you have adequate insurance coverage for your business assets, liabilities and income. Set aside funds to cover unexpected expenses or downturns in business and use clear contracts to protect against client disputes and non-payment

When cutting corners adds time!

When we say ‘cutting corners’ we think of ‘saving time’ but installers of D-Line trunking know this old adage is not always applicable!

To route cabling in occupied premises, probably the biggest time-saver will be opting for a surface mount installation With that decision made, as an alternative to traditional trunking, D-Line’s unique blend with decor solutions can be a no-brainer when time, safety and appearance matter

If the surface-install plan is decided to be the most effective, it helps to think

about corners.

With traditional trunking systems, navigating 90˚ corners usually requires careful measuring before cutting lids to form the gaps needed to accommodate a bend

Alternatively, mitre cutting two adjoining lengths at 45˚ can be tricky and unforgiving of rough or oblique cuts

In comparison, by using D-Line trunking the lid is always attached, in a patented one-piece design, so the corner accessory can simply push-fit over top of the lid. There’s no need to cut the D-Line trunking lids separately!

D-Line bends and tees have grip tabs underside, that lock behind the lengths. No precise measuring is needed, and any poor cut to a length end is covered by D-Line’s clip-over benefit

In contrast to traditional trunking bends and tee connections, to secure D-Line accessories there’s no need to (1) carefully measure space for the D-Line accessory, no requirement (2) to remove the lid, or (3) to cut lids, so no need to (4) reattach lids on the opposing lengths

By not cutting corners, compared to traditional trunking, using D-Line eliminates four ‘traditional trunking’ processes

D-Line products are available from all leading wholesalers
