Editor’s Viewpoint

Busy sparks can finally call the shots It would be hard to argue that this is an easy time to be a trade professional. The wider world feels unsettled, confidence is fragile, and many households are watching every penny. From inflation that refuses to fully behave, to political noise and global uncertainty, it can feel like we’re all working against the current. On the ground, that translates into delayed decisions, customers scrabbling to save money, and the stress of juggling rising costs with the need to stay competitive. Yet, beneath that surface-level gloom, there are some genuinely encouraging signs for the trade – especially looking ahead in 2026. A new “UK State of the Trades 2025 26” report from Jackson Woodturners, based on a survey of more than 500 UK tradespeople, paints a picture that should give electricians pause for thought – in a good way. According to the study, tradespeople expect to increase their prices by an average of 9.5% this year, with electricians specifically forecasting a rise of around 10.1%. That would take average day rates from roughly £300-£500 in 2025 to an estimated £330-£551 in 2026. Those figures aren’t plucked from thin air. They reflect a market where demand continues to outstrip supply. More than a third are booked well into March and almost one in five won’t have availability until April earliest. For sparkies, that level of forward work is not just reassuring – it’s leverage. Of course, none of this is happening in a vacuum. The same report highlights just how challenging 2025 was. Nine in ten tradespeople reported disruptions to their work, with rising costs cited as the biggest headache, followed closely by customer cancellations and late or withheld payments.

Add in the fact that 85% of tradespeople say customers pressured them to reduce quotes in 2025 – with requests for “cash discounts” still rife – and it’s clear that the job hasn’t suddenly become easier. But there’s a subtle shift underway. As Lucie Levesley, Director at Jackson Woodturners, points out, being booked months in advance puts tradespeople in a position to set prices that reflect both their skill level and the true cost of doing business. For electricians, that’s particularly relevant. Electrical work is highly regulated, safety-critical and increasingly complex, whether it’s EV charging, renewables integration or modern consumer unit upgrades. This isn’t commodity labour – it’s professional, specialist work. What’s encouraging is that many electricians appear to be recognising that fact themselves. The research shows that 81% of tradespeople plan to raise prices this year, with nearly a third looking at increases of 11% or more. That suggests a growing confidence to push back against the race to the bottom and charge rates that are sustainable. The world may still feel like a difficult place, and no one should pretend the pressures will disappear overnight. But demand for skilled electricians isn’t going away. If anything, it’s intensifying. With careful planning, clear communication with customers, and a willingness to value their own expertise, 2026 could be a year where sparkies not only stay busy, but finally start getting paid what the job is really worth. Have a good month and we hope you enjoy the issue.

Ellis Stevenson wins SkillELECTRIC gold Twenty-two-year-old Ellis Stevenson has made history by becoming the first ever female winner of SkillELECTRIC, after claiming gold at the 2025 UK Final held over three days at Bridgend College. Ellis, a recently qualified apprentice from SECTT and UHI Moray and now employed by Campbell & McHardy in Moray, Scotland, delivered an outstanding performance in a demanding final that formed part of the WorldSkills UK national competitions in South Wales. Taking silver was Adam Souter, also from SECTT and UHI Moray, while the bronze medal went to Fabian Maciejewski of East Goscote Electrics and Leicester College. Ewan Forsythe, trained at Belfast Metropolitan College and employed by Nugent, received a Highly Commended award following a strong performance. Ellis previously competed in SkillELECTRIC 2024 but did not progress beyond the heats. Determined to improve, she returned in 2025, won her regional heat and went on to secure first place in the final. Organised by National Electrotechnical Training (NET) in conjunction with WorldSkills UK, SkillELECTRIC is delivered with support from NICEIC and Scolmore Group. The competition is designed to

test the core competencies of qualified electricians while highlighting pathways into low-carbon technologies. Finalists were tasked with completing a complex electrical installation within a strict timeframe, assessed against criteria including wiring and termination, inspection and testing, and fault-finding. This year’s challenge also incorporated solar PV, supported by NICEIC, and EV charging technology, supported by Rolec. Speaking after her win, Ellis said: “I’m completely shocked – I really didn’t expect to win. When I heard my name, it took a moment to sink in. I’d like to thank my tutor, Iain McBean, whose support has been incredible throughout.” Jennie Phung, SkillELECTRIC Project Manager at NET, said: “The standard of work was once again excellent. We were particularly encouraged to see returning

competitors recognising the value of the competition. Ellis is a fantastic ambassador for female electricians and for young women considering a career in the sector.” All finalists received a range of prizes, with Ellis also awarded the Megger MFT-X1 multifunction tester and DeWalt power tools. The 2026 SkillELECTRIC competition opens in March. GET MORE DETAILS ABOUT THE 2026 SKILLELECTRIC COMPETITION AT: WWW.RDR.LINK/EBV001

COMMENT

“CODING IS MORE THAN JUST A TICK-BOX EXERCISE.”

Despite growing managerial pressures and the proliferation of best practice guides and literature, Approved Electrician, Anthony Squires MIET, reminds electricial professionals of the importance of using their own engineering judgment when carrying out EICRs. ICRs remain one of the most important safety tools at our disposal, but their value depends entirely on the competence and autonomy of the person completing them. While the industry benefits from structured documents such as Best Practice Guides, it’s my view that these should always be treated as guidance only – a starting point for thought, not a substitute for engineering judgement. After all, no single guide can account for the specific risks, environments, or occupants present in every real-world installation. The responsibility for accurate coding rests with the inspector, and this is where autonomy becomes essential. Our duty is not simply to follow a flowchart, but to justify each observation against BS 7671 and the fundamental legal duties placed on us as electrically competent persons. When challenged, the only defensible position is one grounded

in regulations, engineering reasoning, and a clear, evidence-based audit trail. Look beyond the obvious A robust EICR assessment should always extend beyond what is physically visible. Environmental conditions must be considered, including any increased fire loading, the presence of combustible materials around equipment, or the likelihood that a thermal event could restrict safe egress – especially within the main means of escape. The vulnerabilities of the occupants must also be taken into account. A scenario that may present “lower” risk in a standard dwelling may represent a significantly heightened danger to vulnerable residents with reduced mobility, cognitive impairment, or limited escape options. In short, coding is not a tick-box exercise. It is an engineering activity requiring reasoning, professional autonomy, and the courage to stand

16 February 2026 PROFESSIONAL ELECTRICIAN

“Our duty is not simply to follow a flowchart, but to justify each observation against BS 7671...” behind your decisions. As scrutiny in our industry continues to grow – from clients, regulators, and fire authorities – the ability to clearly and confidently defend your coding using actual regulations is no longer optional, it is the hallmark of a professional. By rooting our decisions in BS 7671, applying engineering judgement rather than defaulting to generic guidance, and always considering the real-world environment and the people we serve, we can ensure that our EICRs are accurate, defensible, and aligned with the fundamental purpose of electrical inspection: protecting life.

THE TRAINING GROUND I’ve heard that AM2 certificates have gone digital – how does this work? NET has launched a new e-certification system that allows you to view and share your AM2 certificate via a secure online portal, and also order a printed copy to arrive in the post. It’s currently only available to people who received their assessment result from 6th December 2025 onwards. During 2026, we’ll be looking at if it’s possible for historical AM2 candidates to access an e-certificate. For those who are eligible, all you need to do is register for the e-certificate system. Once your registration has been verified, you will be able to view your AM2 certificate online, share via a QR code and also invite a ‘Connection’ – such as a potential employer – to view your certificate via the secure portal. The are many benefits of this new service – not least the fact you can get lifetime access to your AM2 certificate online. This is a great help if you lose or misplace your printed copy, which can often happen. From an industry perspective it also increases security and reduces fraud when seeking proof of competence. Your first printed copy is free regardless of when you order it. So, even if you don’t want one straight away, you can order one at any point in time If you’re an apprentice in England, your apprenticeship completion certificate will still be processed separately by the Department for Education and is not part of the AM2 e-certificate system. Take a look at the information on NET’s website for full details on the e-certification process. GET MORE INFORMATION AND ADVICE FROM NET BY VISITING: WWW.RDR.LINK/EBV004

Q. WHAT HAPPENS TO EMERGENCY LIGHTING IN THE SITUATION OF A POWER CUT? DOES THE INTERNAL MEMORY RESET? DOES THIS THEN AFFECT THE ANNUAL THREE-HOUR TESTS?

Self-test emergency luminaires are designed to withstand power interruptions and do not lose their internal memory during a power cut. Test history, fault records, and the test schedule are stored in a non-volatile memory bank, so data is retained even when mains power is lost. When power is restored, the luminaire resumes normal operation and continues its test regime in line with its original schedule. A power cut does not reset or invalidate the annual three-hour duration test, although the test may be delayed until the battery has sufficiently recharged. Scheduled tests include monthly functional tests and annual duration tests, with results stored in memory. All self-test luminaires display status via a bi-colour LED. Stand-alone fittings will be manually monitored, while addressable systems log data centrally. Typical LED indications are: ● ● ● ● ● ● ●

Solid green – Mains present, no fault Slow flashing green – Charging Fast flashing green – Test in progress Single red flash – Battery fault Double red flash – Lamp fault Triple red flash – Duration test failure Off – No mains supply

Test faults can occur for many reasons, such as batteries not fully charged or low temperatures that can affect battery performance; in many cases, a re-test after full recharge will clear the fault without component replacement. In summary, a power cut does not reset the luminaire’s memory, does not erase test records, and does not invalidate the annual three-hour test, although it may temporarily delay testing until battery conditions are suitable.

THE

CODEBREAKERS CHARLIE JONES: THIS WAS A BRAND NEW EV CHARGER INSTALL. THE CONTRACTOR CAME BACK TO RECTIFY IT EVENTUALLY, BUT HOW IS THIS KIND OF WORK BEING SINGED OFF? THE MORE YOU LOOK AT THE IMAGE THE MORE YOU FIND! As a new Electric Vehicle Charge Point (EVCP) installation, it would not normally be considered for periodic inspection and testing. The standard of workmanship observed here is therefore of particular concern. The installation is non-compliant with BS 7671, including the requirements of Section 722, and would require rectification works to make sure the installation is compliant prior to the issuing of the Electrical Installation Certificate. The EVCP cable has not been adequately supported where it terminates within the external intake enclosure. This lack of support would place strain on the terminations and connections. The extended meter tails from the connection blocks to the open connector block have resulted in exposed live parts. This presents a clear danger to anyone accessing the external intake enclosure – DNO, meter operators and the householder reading the meter. The EVCP current transformer (CT’s) conductors also appear to have been terminated within a floating connection unit, which again would place strain on the cables and terminations. C Therefore, the classification code would be a C1, Danger present, risk of injury, immediate remedial action required due to the presence of exposed live parts.

The Observations, Regulation infringements and Codes applicable to this observation would be:

416.2.1

Cables, conductors and terminations not supported to prevent strain 522.8.5 on connections

DAVID SIMPSON: I SAW THIS ON A RECENT JOB – IT’S THE MOST DEGRADED CABLE I'VE EVER SEEN. I THINK IT MIGHT BE A GOOD EXAMPLE OF CABLE (NOT) SUITABLE FOR THE ENVIRONMENT. When designing an electrical installation, selecting the correct cable for the environment is critical for the wiring system to remain safe and serviceable for its expected lifetime of the installation. In this case, the cable that has been utilised for this installation appears to be a flexible cable that has deteriorated significantly. The damage is likely due to eﬀects of ultraviolet radiation, adverse weather conditions or possible vermin damage, resulting in the almost near total breakdown of the outer sheath insulation. At present, there does not appear to be any exposed live conductors, as the internal insulation remains intact, but this would only be a matter of time before it occurs. Although the cable clips do seem to be still supporting the cable in places, they do not mitigate the underlying deterioration. Therefore, the classification code would be a C2, Potentially dangerous, urgent remedial action required due to D damage to the outer sheath of the the cable presents an increased risk of insulation failure.

The Observations, Regulation infringements and Codes applicable to this observation would be: Cables not suitable for the external influences the wiring system have been subjected to for the environment

HOW TO USE LOG-LOG GRAPHS In electrical engineering, graphs and charts serve as an essential tool for communication and data representation. The aim of this article from the experts at NICEIC is to look at graphs that speciﬁcally use log-log scales. Such graphs can oﬀer a convenient way to analyse and visualise data in an easy and understandable format once their construction is understood. It is therefore important that electrical contractors are aware of how to read and interpret these graphs.

Note: This article will focus on those found in Appendix 3 of BS 7671 and those issued by manufacturers to assist in the selection of overcurrent protective devices. Logarithmic scale Log-log paper is a resource that makes use of the logarithmic scale where each incremental unit is arranged in a series of uneven bands grouped within repetitive cycles, and which signifies either a tenfold increase or decrease in a quantity. Logarithmic graph paper is a useful way of representing data that covers an extensive range of values1. For instance, it may prove difficult when needing to accurately display data ranging from, say, 0.01 to 1 000 000 on the same scale. However, displaying such information may be achieved using a logarithmic scale that allows each cycle to represent a distinct range, as shown in Fig 1a. Consider the log-log paper in Fig

1a, the horizontal axis starts at 1 within the first cycle which then increases in single lines unevenly spaced to a value of 10. Each subsequent line within the next cycle then represents an increase of 10 up to a 100; then similarly, each further line represents an increase of 100 and so on until 10 000 is reached. Likewise, the vertical axis starts at 0.01 and progresses up to 10 000 in similar steps. However, representation of these values remains undefined until the axes are labelled. The graph shown in Fig 1b shows the characteristic curve of a 32 A fuse to BS 88-2 where the vertical axis shows time (s) and the horizontal axis shows prospective current (A). To demonstrate how to interpret

such a graph, let’s assume a prospective fault current of 250 A has been calculated; the red dotted line intersects the fuse characteristic curve which indicates that the fuse takes approximately 0.4 s to operate. Characteristic graphs in Appendix 3 There are two important observations about the time/current characteristic curves given in Appendix 3 of BS 7671: i. The curves have been cropped at 0.1 s. For disconnections times less than 0.1 s, it becomes necessary to refer to manufacturers’ data. ii. In relation to the curves associated with protective devices to BS EN 60898, the slowest operating times are shown.

1 Logarithmic graph paper can be either log-log, where both scales are logarithmic, or log-lin, where only one scale is logarithmic and the other is linear.

Manufacturers’ charts Where fault conditions result in very short disconnection times of less than 0.1 s, the characteristic curves detailed in Appendix 3 are no longer applicable. The designer will therefore need to consult manufacturer’s data to determine the let-through energy (I2t). Such issues with short disconnection times are generally more of a concern on commercial and industrial installations rather than in a typical domestic installation. The ability of a cable to withstand

the energy during a fault and subsequent increase in temperature is dependent on its cross-sectional area (S), resistivity, temperature coefficient, heat capacity of the conductor material, and the appropriate initial and final temperature (k). The ‘let-through’ energy generated during the period of the fault is given by the formula: I2t Whereas the thermal ‘withstand’ formula for a cable is given by: k2S2 As such, it is important to remember that the value of k2S2 for the cable is not less than the value of let-through energy (I2t) quoted by the device manufacturer, i.e. I2t < k2S2 (434.5.2). An example chart demonstrating the energy let-through against prospective short-circuit current is shown in Fig 2. Based on the previous example and graph of Fig 1b which considered a 32 A BS 88-2 fuse, what would happen when the fault current is increased to 3 000 A rather than 250 A? From the characteristic curves given in Appendix 3 of BS 7671 it is evident

26 February 2026 PROFESSIONAL ELECTRICIAN

that the disconnection time will be less than 0.1 s and, therefore, manufacturer’s data will need to be assessed. Using the graph in Fig 2, with a fault current of 3 000 A, the let-through energy (I2t) is about 12 000 A2s. Providing the product of the k factor (Table 43.1 of BS 7671) and the conductor cross-sectional area, both squared (k2S2), is greater than 12 000, compliance with regulation 434.5.2 will be achieved. Summary Log-log graphs are a vital tool used in electrical engineering for analysing and visualising data across an extensive range of values. This article has explained the use of log-log scales, particularly as used in Appendix 3 of BS 7671. Where fault conditions result in a very short disconnection time of less than 0.1 s, manufacturers data charts should always be considered when selecting suitable overcurrent protective devices.

POLLUTION DEGREE CATEGORIES Hager’s Technical Training Manager, Paul Chaffers, discusses pollution degree classifications of circuit-breakers, considering the effects of external influences associated with outdoor installations. ollution degrees help manufacturers and designers select appropriate circuit-breakers and enclosure designs based on the operating environment inside the enclosure. The presence of dust, moisture, or conductive particles can significantly degrade insulation performance, especially in ventilated or outdoor installations.

What is pollution degree? Pollution degree (PD) is a classification defined by standards such as IEC 60664 (Insulation coordination for equipment within low-voltage supply systems: Principles, requirements, and tests) and referenced in BS EN IEC 61439 (Low-voltage switchgear and controlgear assemblies) and in circuit-breaker product standards BS EN 60898 and 60947-2. It describes the expected level of environmental contamination that could

affect the dielectric strength of insulation within electrical enclosures. This classification is critical for determining clearance and creepage distances, which are essential for ensuring safe operation and preventing insulation failure. See Fig 1 for a better understanding of each category. BS EN IEC 61439 sets out the requirements for low-voltage switchgear and controlgear assemblies and mandates that the pollution degree of the internal environment must match the insulation requirements of the components used. For example, if internal components are rated for PD2 conditions, but the enclosure is installed in an environment where non-conductive pollution may become conductive due to condensation, the risk of dielectric breakdown increases. This scenario requires careful design

consideration, using measures such as: ●

●

Use of filters or sealed compartments to limit ingress of contaminants Heaters or ventilation systems to prevent condensation Upgrading internal components to withstand PD3 conditions (if appropriate to the installation type)

Circuit-breakers to BS EN 60898 BS EN 60898 is the British Standard for low-voltage circuit-breakers for overcurrent protection in household and similar installations. It states that circuit-breakers to BS EN 60898 are intended for use in environments with PD2 conditions but allows for installation in environments with a higher pollution degree, provided enclosures offering the appropriate degree of protection are used. Circuit-breakers to BS EN IEC 60947-2 BS EN IEC 60947-2 is the British Standard for low-voltage circuit-breakers used in industrial, large commercial, and similar installations. It states that, unless otherwise specified by the manufacturer, a circuit-breaker is intended for installation under environmental conditions classified as PD3. Environmental conditions In many applications, ventilation is key

“... installers should not be concerned about using BS EN 60898 circuit-breakers in outdoor enclosures, provided the manufacturer has tested and validated the assembly arrangement as suitable for such use.” to the eﬀective operation of enclosed equipment, especially where heat is generated. It helps maintain performance by keeping internal temperatures within design limits. To reduce enclosure size and cost, natural ventilation using louvres, slots, or vents is commonly used (see Fig 2). When properly positioned, these features can protect against dust and occasional dripping condensate and can be of any length, provided they meet test standards. Ventilation also helps reduce internal condensation caused by temperature and humidity changes. However, it is important to note that ventilated enclosures do not fully isolate the internal environment from the external one. Therefore, pollution degree categories must be considered. BS EN IEC 61439-1 refers to pollution degrees in relation to environmental conditions, including relative humidity and condensation. It highlights that the pollution degree to which devices and components are exposed inside the assembly enclosure (the microenvironment) may differ from that outside the enclosure (the macroenvironment). This difference is due to protection offered by enclosures with specific IP ratings, ventilation, internal heating, or other methods. Outdoor applications For large commercial and industrial outdoor installations, circuit-breakers

Fig 2. Ventilated equipment

conforming to BS EN IEC 60947-2 are recognised as suitable for PD3 conditions (environments where condensation and conductive pollution are expected). This makes them ideal for outdoor use in these settings. However, these devices are intended to be operated only by instructed or skilled persons. In residential applications, there is a limitation: BS EN IEC 60947-2 circuitbreakers are not suitable because they are not designed for operation by ordinary persons. Instead, circuitbreakers to BS EN 60898 must be used in domestic settings. While this standard is based on PD2 conditions (where only non-conductive pollution occurs), it does acknowledge that temporary conductivity, such as that caused by condensation, may occasionally be expected. Therefore, installers should not be concerned about using BS EN 60898 circuit-breakers in outdoor enclosures, provided the manufacturer has tested and validated the assembly arrangement as suitable for such use. In addition to standard switchgear assembly tests such as short-circuit and temperature rise testing, Hager carry out a range of additional tests which exceed the minimum requirements, including condensation and freeze testing. This is to ensure compliance under extreme weather conditions. The enclosure’s intended application, as specified and approved by the original manufacturer, must be clearly documented. For example, a general designation such as 'Outdoor' suggests suitability for typical outdoor environments. However, if there are specific limitations, these must be

explicitly stated, for instance, 'Outdoor use without direct exposure to sunlight'. Conclusion Specifying switchgear and controlgear assemblies for outdoor applications can be a complex task, often accompanied by understandable hesitation due to the need to meet a number of stringent standards. Installers should be aware that when an empty enclosure is purchased and populated independently, the responsibility for compliance with BS EN IEC 61439 shifts to the installer (who is now the assembly manufacturer with the corresponding obligations). This includes ensuring the assembly meets all relevant performance and safety requirements. One effective way to mitigate this risk is by selecting equipment that has been tested and validated for outdoor conditions, including features such as relative humidity and condensation control. Doing so not only simplifies compliance but also enhances reliability and long-term performance in challenging environments.

Dr. Zzeus IN THIS REGULAR COLUMN, DR. TOM BROOKES, MD AT ZZEUS TRAINING AND CHAIRMAN OF THE BSI TECHNICAL COMMITTEE FSH 12/1 INSTALLATION AND SERVICING, ANSWERS YOUR QUESTIONS RELATED TO FIRE SAFETY. IN THIS MONTH’S EDITION HE LOOKS TO CLEAR UP SOME RECENT INDUSTRY MISCONCEPTIONS. One of our clients, for whom we conduct fire risk assessments, has been told that across 74 buildings they must now install lift-up clear covers retrospectively on all their manual break-glass call points. They were told it was a major nonconformity because if they have some with cover and some without, it's not the same action. Is this true? It would cost the charity a significant amount of money, rather than being used for people in need. The short answer is no, it is not correct. British Standards are not retrospective; BS 5839-1:2025 is a code of “Best Practice”. Here’s why: I’ve recently been made aware that misinformation circulating on social media claims precisely that if there is no MCP cover, it is a major nonconformity. This is totally incorrect for two reasons: 1) It is not retrospective, which means only new installations need to have lift-up clear covers on them to protect from accidental activation. If a site experiences frequent false alarms with a call point, it is recommended that a cover for false-alarm management be installed. 2) Someone has misinterpreted what “same action” means The action of a manual break-glass call point is either “thumb press” or “hit with a hammer” and has nothing to do with lifting the

cover. Clause 44.1.2 lists what we think are Major areas of non-conformity (listed below). If you are taking over maintenance of a fire system, these should all be documented. Major nonconformances that are listed in BS 5839-1:2025 clause 44.1.2: 1. An incorrect number of manual call points to meet the requirements of Clause 19. 2. The method of operation of all the manual call points is not the same – “Thumb press” or “hit with a hammer”. 3. The provision of fire detection is insufficient to conform to the category of system the installation was designed to meet. 4. Heat detection in bedrooms. Again, this is not retrospective. 5. Sound decibel levels that are below the recommendations in Clause 15. 6. Standby battery power supplies that are below the recommendations in 24.3. If there is no standby power supply, it breaches the requirements of the Health & Safety (Safety Signs & Signals) Regulations 1996 7. Non-fire resisting cables are being used rather than fire-resisting cables as required by Clause 25.3. 8. No fault monitoring of the system for power, detection and sounder faults Clause 11.1. This includes auxiliary power supplies and the interfaces through which devices are connected.

9. System integrity that does not meet the recommendations in Clauses 11.2.1, 11.2.9 and 11.2.13. 10. The standards of electrical safety are not in accordance with the recommendations specified in Clause 28. 11. Experience of false alarms, or a history of exposure to them, such that compliance with Section 3 cannot be achieved. 12. Changes to the use, layout, or construction of the protected premises that could affect the effectiveness of the system. 13. Missing zone plan or other correct diagrammatic representation of the building Clause 22.2.5. 14. The fire alarm panel does not have a zonal indication, Clause 22.2. 15. The lack of a facility for the automatic transmission of fire alarm signals from a residential care home to an ARC.

DEMYSTIFYING PEN PROTECTION Viktors Nikolajevs, UK Key Account Manager at CTEK, takes a closer look at the requirements for PEN protection in EV charging applications and dispels a few myths along the way. s the number of electric vehicle charging points in the UK increases at pace to meet UK government Net Zero targets, so there is an increased safety risk from (thankfully rare) open Protective Earth and Neutral (PEN) faults. Should a PEN fault occur, the entire steel body of the vehicle would become energised and when the user comes in contact with it, they will become the only path to Earth. DNOs report approximately 400 faults per year with typically only 1% resulting in electric shocks. But as the numbers of EVs grow, their increased numbers of users are at risk of electric shock during such PEN faults.

When a PEN fault occurs, the user is still at risk of getting an electric shock, even if RCD protection is in place. RCDs will still see the imbalance between the Line and Neutral conductors and break as expected. However, the PE conductor will be eﬀectively live under fault conditions and not break without dedicated means of isolation. The most eﬀective prevention is detecting the fault when it occurs before the end-user comes in contact with an energised vehicle body. Requirements for electrical installations BS 7671:2018+A2:2022+A3:2024 outlines a requirement for PEN fault

protection devices when using PME earthing under clause 722.411.4.1 for chargepoints located outdoors or that might reasonably be expected to be used to charge a vehicle located outdoors. The protection device is supposed to disconnect all live and PE conductors should a fault occur. Alternatively, the clause also permits the use of earth electrodes. However, there is no underpinning BS product standard for PEN protection devices and the clause states that such functionality could be included within the charging equipment. This prompted some EV charging equipment manufacturers to develop a variety of built-in solutions, mostly based

032_PE_FEB26.qxd_Layout 1 06/01/2026 17:23 Page 33

around detection of Phase to Neutral voltage ranges of 207 V to 253 V. Requirements for EV charging equipment standards This approach contradicts the requirements of Section 8.4 of the product standard for all EV charging equipment, BS EN IEC 61851-1:2019 Electric vehicle conductive charging system – General. The section states that for Modes 3 and 4 permanently connected EV supply equipment, protective earthing conductors shall not be switched. EV charging equipment with enabled built-in PEN protection (i.e. the ability to switch PE) do not currently meet the product standard. There is a pending UKonly deviation for this standard that would allow PE switching inside of the charging equipment if the following conditions are met: ●

●

Only manual reset permitted. Automatic reconnection prohibited. Full BSI Kitemark certification via type testing required. Functional test button required.

Not meeting the product standard raises potential issues such as liability in case of injuries and property damage, site insurance policy validity, CE/UKCA marking and certification, and suitability

for grants, such as OZEV, since all of these typically require confirmation of compliance with EN 61851-1. Requirements for OPDD standards IET has recently published IET01:2024 Open combined protective and neutral (PEN) conductor detection devices (OPDDs), which acts as the product standard for devices with PEN protection functionality. The standard describes the operational requirements and their corresponding product markings. Importantly, it increases the operational voltage range to minimise the risks of nuisance tripping in the areas with higher nominal voltage, in some cases from 184 V up to 262.2 V, and in certain cases as far as 273 V. IET01 permits PEN protection to be built-in to the EV charging equipment but drives the point that it must comply with EN 61851-1. This is done in preparation for the deviation mentioned previously and it aligns with requirements such as manual reset only and functional test button requirements for built-in devices. It is important to note, that the extended voltage ranges are likely not to apply to built-in protection devices as EN 61851 will most likely retain the ESQCR voltage references of 207 V to 253V.

Whilst IET01:2024 is not referenced in any other standards or regulations at the time of writing, some of the DNOs have added the compliance with IET01 into the application process. Summary At the time of writing, EV charging equipment with active built-in PEN protection (the ability to switch PE conductor internally) does not meet BS EN IEC 61851-1 requirements in relation to PE conductor integrity within the charging station, pending the deviation. If such devices do not have built-in test buttons and allow for automatic resets, they are also non-compliant with IET01, meaning that some DNOs may reject installation applications. For locations where PEN protection is required, ideally external OPDDs in line with IET01 should be used in combination with EV charging equipment that does not switch PE conductors internally. This will ensure current and future compliance of the EV charging equipment, protective devices and the installation overall. Under Construction (Design and Management) Regulations 2015 (CDM), installers may also be held accountable for using non-compliant equipment, as they may be classed as the system designers. It is the responsibility of system designers to verify the equipment compliance and, if the equipment is found not to be compliant (even if the manufacturer claimed otherwise), the system designers are still completely responsible for the installation design and equipment used. With this in mind, it is always recommended to request the manufacturer’s supply certification from third-party independent bodies such as BSI, Intertek or equivalent, confirming their compliance claims. Please note: information in this article reflects the status of standards at the time of writing and may change.

FEELING THE HEAT With the rise of renewables, battery storage and electric vehicle charging, the demands on our electrical systems are evolving fast. Jonathan Swain, NAPIT Technical Writer, breaks down how contractors must adapt their designs and installations to stay compliant and safe. he way we use electricity in our homes and businesses is changing rapidly. The rise of renewable technologies and electric vehicle supply equipment (EVSE) means that load profiles, even within domestic installations, may be significantly higher than ever before, and for much longer durations. Greater care and consideration must now be taken during the design and installation of these systems, and contractors must evolve alongside the technology. For example: your old college electrical lecturer may have taught you, when positioning circuit-breakers in a consumer unit, to place the highest-rated device next to the main switch and cascade down to the lowest. Historically, this would have (mostly) been acceptable, as these circuits were rarely simultaneously and continuously loaded. In today’s world, however, manufacturer’s instructions may now require devices to be suitably spaced to allow adequate heat dissipation within the consumer unit assembly and to ensure correct operation – particularly when installing systems to supply heat pumps,

battery storage, EV charging equipment and solar PV. These circuits will be drawing, or supplying, significant current for sustained periods, meaning breakers are likely to emit more heat in operation (I2R) than a circuit breaker supplying an average upstairs sockets circuit. There is another crucial factor to consider; not only can these circuits present an increase in load – but also an increase in supply. Solar PV and battery storage systems deliver current into the installation, which has implications for how we select and erect systems to ensure they are suitably rated and not at risk of thermal damage.

The new (fifth) indent states:

What does BS 7671 say? An often-overlooked change in Amendment 2 of BS 7671:2018+A2:2022 is an addition to Regulation 551.7.2, which outlines the requirements for installations where generating sets operate in parallel with other supply sources. Solar PV and battery storage systems operating alongside a primary DNO (Distribution Network Operator) supply fall within this regulation.

This regulation requires that the common parts of the installation shall be suitably rated for the combined current that could be simultaneously delivered by each supply source. In electrical installations without parallel supplies (i.e. from generating sets, fed from a single point of supply), an upfront device typically provides overload protection to a consumer unit and ensures

Fig 1: InA ≥ In + Ig(s) is not achieved. 100 A (In) + 16A (Ig) = 116 A which is greater (not less) than the 100 A consumer unit rating (InA). The example is non-compliant

PROFESSIONAL ELECTRICIAN February 2026 35

035_PE_FEB26.qxd_Layout 1 06/01/2026 17:29 Page 36

THE CPD ZONE its rating cannot be exceeded. The presence of additional sources, unless correctly conﬁgured, could result in more current being delivered to connected loads, with a proportion bypassing the primary protective device and instead coming from the additional source. Failure to account for this in design – resulting in non-compliance with the requirements of Regulation 551.7.2 – could compromise the intended protection of the installation. The potential consequence: thermal damage to an assembly now able to distribute more than its rated current (InA). We will examine three illustrative scenarios showing the impact of the change through Regulation 551.7.2 being put into practice. The intent is to raise awareness of these requirements, especially considering the growing prevalence of multi-source installations. The installations shown are relatively simple to highlight the core concept. In more complex installations, the designer will need to

consider the implications across multiple points of an electrical system. Scenario 1 A 100 A (InA) type-tested consumer unit is connected directly to a 100 A service fuse (In), with a ﬁnal circuit connected to a 3.68 kW inverter with a 16 A design current (Ig). In Fig 1, the rated current of the assembly could potentially be exceeded, making the installation non-compliant. Potential solutions:

1. Install a distribution board rated at 116 A or more (InA). Some manufacturers have tested their 100 A assemblies and can provide a declaration of conformity along with instructions on how to achieve a 116 A conditional rating. 2. If the inverter or gateway has the facility, a Customer Limitation Scheme (CLS) could be provided. G100-compliant electronic control of the loads and supplies may ensure that the assembly rating is not exceeded. 3. If the installations maximum demand permits, an additional overcurrent protective device could be installed to reduce the In value. This would render the installation compliant; the calculation is now satisﬁed, as shown in Fig 2.

Scenario 2 In this example, an assessment of maximum demand shows that the full original supply capacity must always be maintained. Installing a switch-fuse isolator, as in Scenario 1, would reduce available current at certain times, i.e. when the PV system isn’t generating. To resolve this, a dedicated renewables consumer unit has been installed, and the switch fuse repositioned, as shown in Fig 3. By installing the switch-fuse isolator, the assembly is sufficiently protected. The current demanded by the consumer unit cannot exceed its InA rating because of the overcurrent protection provided. All parts of the system are suitably rated for the maximum potential current flow they will be subjected to. In this configuration there has been no loss of available capacity as the full 100 A is still available for distribution at the consumer unit.

Fig 4: The sum of the the load supplying circuit-breakers (32+32+16+6+6) is 92 A. Overload protection is provided to the assembly by these devices and the installation is compliant

Scenario 3 In previous scenarios, the consumer unit had the capacity to demand greater than its rated current due to the quantity and rating of the circuits connected. As the combined capacity of the supplies could sustain this overload, the installation was non-compliant unless additional overcurrent devices were installed. In Fig 4, however, we can see a similar arrangement – but the connected load has been reduced. In BS 7671:2018+A2:2022+A3:2024, there is precedent that, under certain conditions, a

Fig 5: Label to be fitted when the method of compliance is a maximum connected load

device providing protection against overload does not necessarily need to be positioned at the start of an installation, as described in Regulation 433.2.2. It even permits the omission of devices for protection against overload where, because of the characteristics of the load or supply, an overload is unlikely or impossible, as described in Regulation 433.3.1[ii]. In this example, overload is not possible by design, protection is provided by the devices in the consumer unit itself. When this method is used to achieve compliance, appropriate labelling is required, as shown in Fig 5. Conclusion Some argue that the perceived risks described here would only arise if there were already a design failure, specifically, if a part of the installation were overloaded in breach of Regulation 433.1.1. Whilst there may be a degree of truth in this view, it’s important to note that the regulation is a mandatory requirement, and no allowance is made for the application of diversity to meet its requirements. Diversity should never be used as a means of load control and/or overload protection regarding this regulation.

Note: Any intended (and documented) departure from BS 7671:2018+A2:2022+A3:2024 requires special consideration by the designer of the installation, and the resulting degree of safety shall not be less than that obtained by compliance with the Regulations. In counter to the criticism: we’ve heard reports of contractors attempting to overcome supply capacity issues by installing microgenerators. Installations evolve, and are added to throughout their service life and, as discussed, many emerging technologies can represent a significant increase in current demand. In this light, perhaps even the harshest of critics can appreciate the intent and value of the regulation in the face of a rapidly evolving industry. Traditional, linear supply arrangements are increasingly supplemented by additional sources. Designers must now factor in new dimensions of current flow and protective coordination to ensure safe, compliant installations.

In this article the experts at IDEAL Electrical oﬀer step-bystep guidance on using a circuit tracer to identify a dead short.

DEAD SIMPLE ircuit tracers play a vital role in modern electrical work, helping to streamline fault-finding and improve efficiency. Consisting of a transmitter that sends a signal through conductors and a receiver that detects it, a circuit tracer permits electricians to quickly identify which breaker or fuse protects a circuit, trace concealed conductors, and locate electrical faults. Troubleshooting can be a time-consuming task, but a circuit tracer makes it a faster, one-person job. A dead short is one type of fault that highlights the true value of a circuit tracer. This fault occurs when current flows along an unintended path with no resistance, leading to a hazardous level of current in the circuit that can damage equipment and put workers at risk. Attempting to locate such a fault manually can be time-consuming, as the associated protective device will trip almost instantly to prevent damage. Manual testing might involve individually isolating and inspecting each device along the circuit, a lengthy and frustrating process. A circuit tracer provides a powerful, time-saving solution. With a tracer in hand, electricians can quickly and accurately pinpoint a dead short. But how exactly can a circuit tracer be used in this way?

Finding a dead short Before using their circuit tracer, electricians must ﬁrst prepare for the testing. To prepare: 1. De-energise the circuit. This is essential to avoid electrical hazards.

2. Disconnect any connected devices to eliminate potential interference. 3. Inspect the wiring visually for obvious signs of damage, such as burnt insulation or exposed conductors. Next, electricians should turn on and use the circuit tracer transmitter. Advanced transmitters such as the SureTrace Plus and SureTrace Pro transmitters include a built-in automatic continuity test, which can be used to identify the shorted conductors. The circuit tracer receiver can be used to pinpoint the short. The receiver detects the signal that the transmitter sends through the conductors. 1. Turn on the device and adjust its sensitivity levels. 2. Scan the circuit by moving the receiver along the conductor run. 3. Follow the highest signal reading, which indicates the path of the circuit. 4. Reduce sensitivity as you approach the suspected fault to pinpoint the exact location. 5. Follow the circuit until the receiver registers a sharp drop in signal strength – indicating the likely location of the short. How to use an inductive sensing clamp for non-contact testing In some cases, accessing the conductor termination points to connect the transmitter may not be possible or safe. Instead, electricians can use an inductive sensing clamp for a non-contact solution. By placing the clamp around a conductor

at any accessible point along its run, the clamp can induce a signal without a direct connection. Then, the receiver can be used in the same way to follow the signal and locate the fault. The SureTrace Pro includes an inductive clamp in its kit, providing a versatile troubleshooting tool for non-contact fault-finding. Fast, accurate fault-finding Circuit tracers enable faster, more accurate troubleshooting, turning the process of locating dead shorts and other faults into a straightforward task. Whether using the transmitter or an inductive sensing clamp, electricians can easily inject a traceable signal into the circuit and use the receiver to pinpoint the fault. By following these steps, electricians can work more efficiently, save valuable time, and find dead shorts with ease. GET MORE DETAILS ON THE IDEAL SURETRACE PRO BY VISITING: WWW.RDR.LINK/EBV014

WEATHERING THE WORKDAY From waterproofing to flexible tech, Nick Poulson at Carhartt explains how understanding the labels behind a jacket can better help you pick the right one for the job. utdoor conditions move fast at this time of year; cold mornings, sudden showers, and wind picking up on exposed sites, so the right jacket is as important as the right tool. With so many labels and technologies to choose from, it’s not always obvious what each one oﬀers but understanding the diﬀerences helps you pick a jacket that actually supports the way you work.

Your best defence A waterproof coat is an essential in winter but it isn’t much use if it leaves you soaked in sweat and then cold and clammy as you dry. A breathable but waterproof membrane makes a big diﬀerence on-site. Storm Defender is a label you will see on a number of Carhartt jackets and is designed to block out heavy rain while still

letting vapour escape so you stay dry from the weather and from your hard work. The Loose Fit Heavyweight Jacket has the Storm Defender membrane paired with a roll-away hood, storm flaps and an adjustable droptail hem to prevent any little drips and draughts that might creep in. For lighter, packable layers, the Monterey Jacket (available in men's and women's versions) also incorporates Storm Defender but is much lighter and can be packed away into its own pocket when not needed. Flexibility when you’re working is always important, so if you’re looking for a jacket with plenty of movement, opt for clothing that has Rugged Flex or Full Swing on the label. Rugged Flex has stretch built into tough fabrics. Duck canvas for example, is naturally stiff when new, so adding flex in key areas like elbows, shoulders and across the back, means you can reach, climb and lift without feeling restricted. The Duck Chore Coat combines this flexibility with wind resistance and its loose fit makes it a great option if you want to layer up underneath. Full Swing takes a different approach. Instead of adding stretch, it alters the cut of the jacket so your arms and shoulders can

42 February 2026 PROFESSIONAL ELECTRICIAN

move more freely. Developed with input from the Carhartt Crew (a group of working testers), Full Swing reduces strain by giving you more room where you naturally need it. The Bartlett Active Jac incorporates both Rugged Flex and Full Swing, is insulated and lined with quilted taffeta. Home comforts Some jobs call for warmth without bulk, others for wind protection and others for something that feels at home both on-site and off it. That’s where Carhartt’s Montana range sits. This collection is made up of durable, cold-weather workwear, including insulated jackets and vests, all in a Western style. Montana jackets and vests use rugged duck fabrics and are made for cold weather. The Montana Rugged Flex Relaxed Fit Duck Insulated Jacket will keep you warm, even in freezing conditions, while the Montana Duck Vest offers the same kind of warmth but without sleeves so it’s ideal for layering. The Montana Active Jackets use Wind Fighter technology and insulated duck canvas for dependable warmth but also have striking knit panels created by designer Bethany Yellowtail, for a distinctive look.

Dave Elson, Compliance Manager for Werner UK, advises on how electricians can get ahead this winter by following essential safety guidance on-site.

STAY ONE STEP AHEAD ith the colder weather firmly setting in and warnings of ‘Arctic blasts’ set to freeze parts of the UK, at Werner we’re urging tradespeople to act now to ensure they’re ready for the additional challenges that come with working at height at winter. According to the latest Health and Safety Executive (HSE) figures, falls from height remain the leading cause of workplace fatalities in Great Britain, accounting for more than a quarter of all deaths at work in 2024-25. In construction, that proportion rises to more than half. As the days grow shorter and temperatures begin to fall, these risks are only likely to increase. That’s why we’re encouraging those working at height to take proactive action now to ensure their site safety protocols are up to scratch. Once the frost arrives, it’s already far too late to start thinking about winter safety. Cold weather, wind and reduced daylight can all have a major impact on site conditions. By getting ahead now – reviewing training, checking equipment and planning for harsher weather – you’ll keep yourself and your team one step ahead of the risks. Werner’s guide contains a series of do’s and don’ts for tradespeople to

consider, part of our ongoing commitment to promoting safe working at height at every turn. They include: DO wear the right clothing The first line of defence against the cold is the right workwear. A good rule of thumb is the three-layer system: a moisture-wicking base layer to keep sweat away from the skin, an insulating mid-layer such as a fleece, and a waterproof, wind-resistant outer shell. Gloves, boots and hats are equally important, and a high-visibility or reflective outer layer helps keep workers visible in darker mornings and early evenings. DON’T skip risk assessments Every job should begin with a thorough risk assessment, but it’s even more critical as conditions worsen. Cold, wet or icy surfaces, wind gusts and reduced visibility can all compromise stability when working at height. Regularly check ladders and platforms for corrosion, loose fittings or signs of wear – particularly after a frost or heavy rain – and ensure equipment is stored under cover where possible. DO plan for changing conditions As daylight hours shorten, ensure there’s adequate lighting on-site so hazards such

as slick surfaces are visible. Installing non-slip mats or grates can reduce the likelihood of slips and falls. Always monitor forecasts and be ready to adjust schedules if wind, snow or ice make conditions unsafe. Fatigue also sets in faster in cold weather, so frequent breaks and job rotation can help maintain concentration DON’T neglect training Winter is a good time to refresh health and safety training. Workers should know how to identify seasonal hazards such as cold stress, hypothermia and frostbite, and understand what to do if symptoms occur. Werner has also compiled a series of training resources designed to give tradespeople all the tools they need to ensure safest possible working. I always say that preparation is the best means of prevention. You can’t totally eliminate the risks associated with working at height, particularly in winter, but you can ensure you’ve taken every step possible to mitigate against risk.

“A REALLY WELL-DESIGNED TOOL BAG” Pete ‘Monty’ Monfort, Director of Arena Training Centre and Monty Electrics, takes the Hultafors Ergonomic Tool Carrier for a test drive. ometimes it takes sitting down and properly reviewing a product to make you stop and think about just how much influence a brand has had on the trade. You use their kit day in, day out, often without really giving it a second thought. Hultafors Tools is one of those brands. Part of the wider Hultafors Group, alongside Snickers Workwear, Solid Gear and Hellberg, the company has been around for an impressive 140 years.

Tools for the trade Aside from producing enough slide rules every year to apparently stretch from Sweden to Australia, Hultafors is synonymous with well-made, no-nonsense tools. Axes, saws, knives, measures, drivers, wrecking bars – if it’s something you might need on-site, chances are they make a version of it. So, when I was sent the Ergonomic Tool Carrier to review – along with a few extra goodies including a branded T-shirt, hat and tape measures – I was

genuinely pleased to give it a proper run out on real jobs. This is an open-topped, soft-sided tool bag, and it immediately feels robust without being over-engineered. I loaded it up straight away with my everyday tools and found organisation was one of its biggest strengths. There are loads of side pockets, which makes it simple to keep smaller tools, testers and hand tools separated and easy to grab. The lower front lip is a subtle but clever touch too, letting you stack tools from small to big while still being able to see and access everything quickly. One of the standout features is the ergonomic curve on one side of the bag. It doesn’t sound like much, but when you’re lugging tools around site all day, it makes a real difference. The bag sits closer to your body, doesn’t smash into the side of your knee as you walk, and generally feels like it takes less effort to carry. The base of the bag is a really tough moulded plastic, which keeps everything stable and upright. More importantly, it stops your tools getting wet if you put the bag down outside on damp ground. The main body of the bag is made from 1680 Denier ballistic polyester, which feels seriously tough and more than capable of standing up to the usual knocks, scrapes and general abuse that comes with site life.

One pocket has a particularly nice feature: a built-in waterproof rain and dust cover that simply pulls out and tightens with a cord. I used this recently on a garden job where we were caught in a short spell of rain, and it kept all my tools bone dry. It also came in handy indoors when the joiners turned up and started throwing sawdust everywhere. Because I’d had the foresight to cover the bag, I wasn’t rummaging through piles of debris every time I needed a tool. Everything’s covered The bag also has covered, zippered pockets, which are ideal for carrying more sensitive and expensive equipment safely. The handle is extra deep and well thought-out, meaning your knuckles don’t get battered by larger tools when carrying it around. The rubber-clad grip runs along the length of the handle, making it comfortable to hold and easy to balance, even if the bag isn’t evenly loaded. Strength-wise, it feels like it would take far more weight than I’d ever realistically want to carry, and according to Hultafors it’s tested to a 60 kg static load. There’s also a dedicated steel bracket for tape measures, which holds them snugly and feels just as robust as the rest of the bag. It’s nice to see those

046_PE_FEB26_Layout 1 07/01/2026 11:49 Page 47

small details included, rather than having to clip things on wherever they’ll fit. In use, the bag has been spot-on! The front and back are different heights, which gives you a good overview and easy access from the front, while still offering plenty of support for tools at the back. The central compartment is large and well laid out, with pockets, tool holders, pen holders, elastic loops and even a key clip. Everything has its place, which makes working quicker and less frustrating. Overall, I think this is a really well-designed tool bag. Price-wise it sits a little higher than some of the cheaper alternatives on the market but, more importantly, it feels like something you’ll only ever need to buy once. It genuinely seems indestructible, and that makes the slightly higher price tag feel like money well spent.

“A SET THAT MAKES THE CUT” Steve Hewish, Senior Electrician at Unique Group (SW), gets to grips with the Mandrex SpeedXcut M42 Electricians’ Hole Saw Set. ometimes it’s only when you really put a tool through its paces that you realise just how much time it can save you on-site. Hole saws are one of those items electricians use almost daily, but often just put up with whatever quirks they come with. That’s why I was keen to give the Mandrex SpeedXcut M42 Electricians’ Hole Saw Set a proper test on real jobs. First impressions were very positive with the immediate standout feature being the One Click quick-change arbor system. Compared to traditional hole saw setups, it’s a genuine time-saver. Swapping sizes is quick and straightforward, without having to mess about taking everything apart. When you’re drilling multiple holes in diﬀerent sizes across a job, that alone makes a noticeable diﬀerence to productivity. Another clever detail is the notch taken from the side of each hole saw. This allows swarf and debris to escape easily while drilling, which helps keep the cut smooth and prevents the saw from binding. The electricians’ set I tested comes with hole saw sizes covering most day-to-day needs, and it’s supplied in a tough, blow-moulded case with room to expand if you want to add more sizes later. It also includes spare hole saw

adaptors, which means you can use the Mandrex arbor with existing hole saws if you need a specific size. Mandrex also offers a wide range of sizes, material-specific hole saws, replacement arbors and pilot bits, which are readily available from UK suppliers. Strong performance across multiple taks In use, the hole saws performed well across a range of materials. I tested them on wood, plastic, metal and plasterboard, and they cut cleanly and easily in all of them. The SpeedXcut M42 bi-metal construction, with 8% cobalt, definitely helps here, requiring less feed pressure and producing a smooth cut. The only real negative I found was when drilling metal trunking. There’s no depth stop, so you do need to be mindful of protecting cables behind the material. That said, the hole saw cuts through so evenly that this is a relatively minor issue if you’re paying attention. I’d also recommend using Mandrex’s cooling spray rather than standard spray oil when drilling thicker metal, as the hole saw did get quite warm when cutting through heavier conduit boxes. One particularly useful feature is the

48 February 2026 PROFESSIONAL ELECTRICIAN

long-thread hole saw adaptor included in the set. This allows you to enlarge existing holes, which is ideal for lighting upgrades, replacing old downlights, or adding extra cable entries into trunking or distribution boards. I was also sent the Mandrex quick-lock extension adaptor, which is another well-thought-out addition. If you’re drilling through thick materials, up to 300 mm, the extension clips straight onto the arbor without tools. There’s no need to strip anything down, unlike many other systems on the market. Overall, this is a well-designed, practical hole saw set that does exactly what electricians need it to do. It saves time, cuts cleanly, and feels built to last.

SMARTER SUSPENSIONS In this case study article we learn more about how Gripple’s new and improved HangPro helped to cut installation time by 30% on a complex retail build. xposed ceilings and beams, and open-plan layouts have become defining features of modern retail environments. While they create bright, open spaces for customers, they present significant challenges for M&E contractors. Installing electrical containment, lighting, and HVAC systems in these conditions demands precision, flexibility, and speed. That was exactly the situation faced by 24-7 Projects, the M&E division of 24-7 Group, during the fit-out of a new supermarket in Harrogate, North Yorkshire. With a glulam beam structure and fully exposed ceiling, the team required a suspension solution that could handle varying drop heights and awkward angles without compromising on strength or finish. Traditional suspension methods, such as threaded rod and strut, were found to be too time-consuming to install. The team also wanted to avoid the additional health and safety risks they can bring through on-site cutting, working at height for extended periods, and hot works.

Project support Working in collaboration from the early design stages, Gripple’s Technical Services team supported the project by identifying the most suitable suspension systems for the structure. Central to the installation was HangPro, Gripple’s next-generation wire suspension system, suitable for hanging a variety of building services like ductwork, cable baskets, lighting, and displays. Designed as a faster, more eﬃcient alternative to traditional methods, the new and improved HangPro accommodates loads up to 55 kg and can be adjusted even under load (when supported), allowing ﬁne-tuning on site. The results? Well, they speak for themselves. The project team achieved an estimated 30% reduction in installation time, saving around 378 hours of labour. HangPro’s adjustability and versatility eliminated the need for on-site cutting or hot works, improving safety and reducing waste.

The team also saved 1,520 kg in material weight and achieved a reduction of 3,451 kg in embodied carbon – supporting both project sustainability targets and broader environmental goals. Beyond the practical advantages, HangPro also helped maintain the project’s architectural intent. Its slim proﬁle and discreet ﬁnish complemented the open ceiling design, ensuring electrical containment and lighting systems blended seamlessly into the retail environment. John Butterworth, Director of New Products at Gripple, said: “We evolved HangPro to make installations faster, safer, and more adaptable for the challenges contractors face today. It’s great to see it performing so effectively on real projects like this.” GET MORE INFORMATION ON THE NEW AND IMPROVED GRIPPLE HANGPRO BY VISITING: WWW.RDR.LINK/EBV020

IS THE PRICE RIGHT? Alan Broom, Technical Support Manager at Contactum, looks at why investing in good quality circuit protection should never be undervalued. t a recent trade show, a contractor told me that MCBs were “a bit expensive.” The irony was that he was holding a large coffee from a well-known chain that cost more than the MCB he was referring to. That coffee was gone in the duration of our conversation. Circuit protection products are built to last decades, comply with stringent safety regulations, and could very well prevent a fire in the home or workplace. It got me thinking – where does the real value lie?

Quality controls When we talk about circuit protection, we’re not dealing with luxury items or passing fads. We’re talking about consumer units, RCBOs, MCBs, and AFDDs that must meet strict requirements set out in BS EN 61439-3, BS EN 61009, BS EN 60898, IEC EN 62606, and BS 7671. These aren’t optional standards – they’re the backbone of electrical safety in the UK. Meeting them properly doesn’t happen cheaply. It demands high-grade materials, rigorous testing, quality control, and continuous development to keep up with evolving safety expectations.

Commitment and pride in standards come from years spent learning the trade from my father – often accompanying him on jobs during the weekends and school holidays. Those experiences instilled a respect for good tools, safe practice, and the importance of doing things properly – lessons just as relevant in circuit protection manufacturing as on-site installation. Counting the cost Contractors understand the importance of doing a job right the ﬁrst time, and it’s the same with circuit protection. Choosing products purely on price might save a few pounds upfront, but the potential cost of failure – in time, call-backs, or even safety – is far higher. Those who work on the tools appreciate this instinctively. The name of the game is to do the job properly, safely and with a smile on your face. It’s not about chasing the cheapest component, but selecting equipment that delivers safety and reliability. There’s also the matter of longevity. A compliant, well-made protective device is designed to perform consistently for years, if not decades. You don’t have to

52 February 2026 PROFESSIONAL ELECTRICIAN

recharge it every night or swap it out every 18 months. Look at the true value Viewed over its lifetime, the cost is not only reasonable, but also excellent value. The upfront price might look higher, but spread across years of protection, it comes out at pennies a week – less than your streaming subscription or, dare I say it, your daily caﬀeine ﬁx. So, the next time someone says circuit protection devices are too expensive, ask them how much they value reliability, reputation, and their customers’ safety compared with their morning cappuccino. One may last ten minutes, the other could last a lifetime. I can only hope that future generations will carry that approach forward. One where quality workmanship and appreciation for properly engineered circuit protection helps ensure the industry remains professional, safe, and sustainable.

WARMTH WITHOUT WASTE The team at Rointe take a closer look at the latest trends in heating solutions and why the brand’s newest launch can offer smart heating that thinks for itself. s modern homes and commercial spaces evolve, the demand for heating solutions that are both energy-efficient and user-friendly has never been higher. For electrical professionals, the challenge lies in balancing compliance, comfort, and installation efficiency – without compromising on design. Rointe’s EONIQ WiFi radiator addresses all of these requirements, offering a next-generation approach to electric heating that combines adaptive technology, flexible aesthetics, and installer-focused design.

Heating that adapts At the heart of EONIQ is Smart Adaptive Inverter Technology, a system that goes far beyond traditional thermostatic on/off control. By analysing room usage patterns and heat demand, the radiator modulates power intelligently, maintaining temperature more consistently while reducing unnecessary energy consumption. The result is smoother, more stable heat, fewer temperature swings, and lower running costs – all without constant user intervention. For installers, this adaptive approach provides a predictable system that meets modern energy regulations and reduces call-back visits caused by poorly set thermostats. It also supports multi-room setups where each zone can operate independently, ensuring energy efficiency across entire properties. Flexible performance, premium finishes EONIQ caters to both practical and aesthetic expectations. Available in five contemporary finishes – White RAL 9016,

Black RAL 9005, Oyster White, Pearl Beige, and Dark Grey – installers can specify units that either blend seamlessly into interiors or act as a statement feature. The radiator comes in three power ratings (600 W, 1,200 W, and 1,800 W), offering the flexibility to match heat output to room size, insulation levels, or project requirements. A slimline form factor ensures that units fit neatly in compact spaces without compromising performance. Digital control, made simple With the Rointe Nexa App, EONIQ can be managed via WiFi Direct, removing the need for additional gateways or hubs. Installation is simplified, multi-room commissioning is faster, and configuration is more straightforward. End users gain access to features such as geolocation-based automation, energy-saving modes, scheduling, and real-time consumption data. For landlords, facility managers, or multi-property owners, Nexa enables centralised control, allowing comfort to be maintained without wasteful energy usage. The App also provides simple remote diagnostics, helping electricians or building managers identify performance issues quickly. Durability and installer focus EONIQ is engineered to perform reliably over time. Its 100% recycled aluminium heating elements provide rapid, even heat, while high-density thermal fluid ensures temperature stability. Advanced surface coatings protect against wear, cleaning, and UV exposure. Silent operation, simple wall-mounting systems, integrated WiFi, and Lot 20 compliance make installation quicker,

easier, and more reliable. The radiator’s intelligent control reduces unnecessary manual adjustments, giving users consistent comfort while lowering service calls associated with poorly configured heating schedules. Challenging misconceptions Common myths about electric radiators are easily debunked with EONIQ. “More watts mean faster heating” is replaced by the reality that adaptive distribution and intelligent control define comfort. “Smart radiators require complex networking” is no longer true thanks to WiFi Direct. And multi-zone heating in apartments or multi-room properties can now be intuitive and manageable via Nexa’s centralised system, giving users confidence that their heating operates efficiently and safely.

A GLASS ACT odern, futuristic buildings come with equally futuristic challenges. And when engineers need to think outside of the traditional control box, they’ll often turn to WAGO. There was a lot to consider when integrated control system specialist, Accurro, started work on Albion Riverside, an 11- storey apartment block of shimmering glass overlooking London’s Thames, as the company’s Co-Founder and Director, Harry Lees, explained: “There is so much glass, it’s a bit like a greenhouse, so part of the scope was to overcome the heat gained from the sun. That was the biggest challenge.” Accurro was also tasked, he said, with controlling the humidity in the building to safeguard the installed artwork, and extracting moisture from the building’s steam room when it wasn’t in use. The client also required leak detection, for insurance purposes, and for all controls to be as easy to use as possible.

Smart thinking To fulfil the brief, Accurro installed a smart HVAC solution. It tracks the sun’s position in the sky and measures radiation levels in real time, then uses this data to automatically control air conditioning, heating, and humidifiers in individual rooms as the day progresses. As well as meeting the client’s practicality requirements, this approach also contributes to the building’s overall sustainability by ensuring the efficient use of power. “Once the resident has set the system to the temperature they are happy with, it controls itself,” said Harry. “It means they always get the optimal energy usage.” Controls and graphics are integrated into the installed touch screens, providing residents with a single, simple interface for audiovisual and HVAC functions, while an automatic extract damper extracts steam from the steam room. Bullet sensor leak detection modules on the floor of the plant room raise the alarm if water is detected, or if pre-set usage parameters are exceeded, indicating a burst pipe. As well as protecting the building and its contents from damage, this further contributes to its green credentials by helping to avoid water waste.

We discover more about how Accurro and WAGO are helping to power residential building automation through the use of smart solutions. Big ideas, small footprint One of the biggest restrictions when designing the system was the size of the plant room, something which is quite common in residential developments, where architects do not necessarily consider the space needed for advanced building management systems (BMS). The solution was WAGO’s 750 series programmable logic controller (PLC). Harry explained: “Generally speaking, you wouldn’t use a PLC in residential building control – they are more for industrial applications. That said, a normal BMS panel is about four times the size of the WAGO PLC.” What’s more, because it’s designed for industrial use, it’s very robust. Harry’s team also used WAGO terminals for underfloor heating manifolds. “These are usually stuck behind cupboards,” he said. “The WAGO clamp system means there are no screws on the terminals, so they’re maintenance-free – you don’t have to check the screws each year to make sure none are loose. This is a huge plus when you’re working on residential properties.” In addition, WAGO’s automation system is open source and vendor agnostic at field level. This, combined with the flexibility provided by the WAGO Codesys Software, allowed Accurro to put its own stamp on the solution, and tailor it to meet the needs of the end user. During the year-long installation, WAGO staff were on hand to promptly answer questions and respond to queries. GET MORE DETAILS ON WAGO’S RANGE OF PRODUCTS AND SOLUTIONS AT: WWW.RDR.LINK/EBV023

Make more impact with Vorteck On today’s sites, impact drivers don’t hold back. They deliver relentless torque that can destroy ordinary accessories in seconds. For electricians working at pace, that power only counts if the accessories can handle it. Twisting bits, slipping sockets, and burnt-out drills don’t just slow the job down, they compromise results. C.K Tools has addressed that challenge with the expanded Vorteck range. Built not just to withstand impact, but to fully harness it, Vorteck is engineered for professionals who expect their tools to keep up with the way they work. And now, the arsenal has grown. Power without compromise Vorteck is designed around one clear principle: convert maximum torque into controlled, reliable performance. Through advanced metallurgy and torsion-optimised geometry, rotational force is channelled eﬃciently, reducing vibration, minimising energy loss, and signiﬁcantly extending service life. This approach delivers more than incremental gains. It represents a rethink of what impact-rated accessories should achieve, ensuring that modern impact drivers can operate at full potential without accessories becoming the weak link. The complete toolkit for real sparks The expanded Vorteck range covers the full spectrum of on-site applications. It includes impact screwdriver bits with magnetised tips and exceptional torsion control, pro cobalt HSS drill bits for reliable

metal penetration, and quick-change sheet steel hole saws designed to reduce replacement costs by up to 30%. The range also features masonry and tile bits with carbide precision, fast flat wood bits that work up to three times faster than standard alternatives, and deep-reach nut and bolt drivers developed specifically for cable trays and threaded bar. Every product shares the same commitment to premium materials, impact-rated performance, and durability that holds up under pressure. Built to suit the way that you work Vorteck accessories are designed around real site conditions. Quick-change hex shanks allow instant swaps. Precision-ground edges bite cleanly without skidding. Pass-through depth solutions handle awkward fixings, while flared collars help prevent over-drilling in electrical enclosures. Magnetised tips keep fixings exactly where they are needed. These are not features added for specification sheets, but practical solutions that support faster, cleaner work across metal, timber, masonry, and mixed materials.
