Tradesmen fined for dangerous electrical work A builder and electrician have been fined for carrying out dangerous electrical work on a domestic property in the Midlands. Kevin John Wakefield, trading as Beta Homes Improvements, and Paul Lloyd, trading as P Lloyd Electrical, both pleaded guilty at Wolverhampton Magistrates’ Court to offences including a banned practice, misleading actions and professional diligence under the Consumer Protection from Unfair Trading Regulations 2008. It followed an investigation by Dudley Council’s Trading Standards team and NICEIC. The court heard how Wakefield was hired to build an extension and install electrics at a house in Dunns Bank, Quarry Bank in 2016. When he finished the job, the householder was plagued with problems which led to an electrical fire. After complaints from the homeowner, Wakefield asked his ex-brother-in-law Lloyd to check the electrical work and issue the necessary certificate. Lloyd issued an Electrical Installation Certificate displaying the NICEIC logo even though he was not, and never had been, registered with the voluntary body. The home owner continued to have issues and asked another electrician to test the electrical installation. The electrician found a host of problems with the installation including no RCD protection on some of the circuits, and one of the circuits being considered so dangerous it had to be disconnected. The electrician also highlighted various errors, missing information and inconsistencies with the certificate, provided by Lloyd. NICIEC was alerted to the concerns and contacted Lloyd about the complaint. Lloyd failed to respond to the allegation so the matter was passed over to Dudley Trading Standards. Wakefield was fined £2,000 and also ordered to pay £1,144 costs, £819 compensation and a victim surcharge of £170. Lloyd was also fined £2,000 and ordered to pay £1,144 costs, £569 compensation and a victim surcharge of £170. Kevan Parker, MD for Certsure, said: “We take a dim view of those who pretend to be registered electricians when they are not. Anyone thinking about using our logo fraudulently will be caught and dealt with appropriately by the courts.”

Jason chooses safety first An electrician has received another timely boost from C.K Tools after suffering an injury last year. Every tradesman is familiar with cable routing and the risks of splinters that can occur. That became a painful reality for Jason Price of Jason Price Electrical Services, whose hand was badly injured last year when a cable rod (from another supplier) splintered during use. Thanks to C.K, Jason became the proud owner of a C.K MightyRods PRO Cable Rod Set, which offers total protection against splinters due to a unique SplinterShield coating. Will Sheridan from C.K originally heard Jason’s story during a visit to wholesaler Seryn Electrical and, by chance, recently met him again during another visit. Jason is still suffering intense pain in his injured hand and an operation to remove the splinter has proved unsuccessful,

leaving the splinter embedded and resulting in ongoing pain. On a lighter note, Will took the opportunity to present a delighted Jason with C.K’s SPIRAFlex rod, to help make his work that much easier. The C.K MightyRods PRO are specifically designed to combat the issues of painful splintering and snapping, thanks to an innovative SplinterShield coating that protects the rods and allows both safe and efficient working conditions. C.K realised that flexibility is also key to successful cable routing and introduced its super-flexible SPIRA-FLEX rod, perfect for accessing tight corners, bends and other obstacles.

Change in law is sparked by Seaward A campaign led by Seaward Electronic has sparked the introduction of tough new rules for landlords to keep private tenants safe. Seaward’s campaign was backed by Easington MP Grahame Morris, who sponsored an Early Day Motion calling for the topic to be debated in parliament. The campaign urged policy makers to change the law to require landlords to carry out regular electrical testing in their rental properties. Mr Morris said: “Seaward’s successful campaign, which has been instrumental in changing government policy, will help to save lives – as well as save families the hardship and pain caused by domestic fires.” But Mr Morris says the government needs to go further to ensure the legislation is implemented as quickly as possible. And Seaward believes the rules need to go further to include portable electrical appliances as well as fixed installations. Five-yearly safety checks Housing Minister Heather Wheeler MP announced a series of measures designed to bring England’s policy in line with that of Scotland. Landlords will be required to undertake five-yearly safety checks, with new guidance being published setting out minimum levels of competency and qualifications for inspectors. Andrew Upton, Managing Director of Seaward, said: “The new rules are an encouraging step in the right direction and I’m pleased the government is taking the safety of tenants seriously. However, it’s disappointing to see that electrical appliances aren’t included in the


legislation this time – and we will continue campaigning to ensure this happens. “I am also keen to see the outcome of the social housing green paper consultation and hope to see similar rules introduced for those tenants.” Andrew explained that quick and simple measures such as portable appliance testing can highlight problems the tenant or landlord may not be aware of, such as simple wear and tear and appliances that don’t meet UK safety standards. Government statistics for 2017-18 show that faulty electrical appliances were the second largest cause of fires in the UK. Despite this there is no legal requirement in place for landlords to regularly test any portable electrical appliances they provide in their rental properties. Mr Morris added: “I welcome the Minister’s announcement; however, we need a clear commitment on when the new legislation will be brought forward and assurances that any phasing of new electrical safety standards will not be prolonged.”

A matter of urgency Electrical Safety First (ESF) has added its weight to the debate by urging government to introduce new laws as a matter of urgency following the death of a University Professor. The comments come after a jury found that John Alliston, 70, of the Royal Agricultural University of Cirencester, was electrocuted by a faulty boiler after touching a live copper wire in his garden in 2017. Electrical Safety First was instrumental in getting the government to agree to legislation on mandatory electrical safety checks in the private rented sector. However, there is concern that, with no timeline laid out for the legislation to become a reality, more tragedies like the death of Professor Alliston could occur. A jury concluded the death was accidental, and he was electrocuted due to the absence of Residual Current Protection, whilst the property had not had an electrical safety check. Phil Buckle, Chief Executive of ESF, said: “The recent, tragic death of Professor Alliston illustrates the importance of this essential safety requirement. Electrical Safety First is extremely concerned that the government has not yet provided a timescale to implement these checks, particularly since it announced its intention of doing so last year.”

Letters PE readers share their thoughts on the big industry-related issues.

Part P is not doing enough for the industry Dear PE I recently wrote to you concerning my own experience with Part P and you kindly published my letter in the March edition of the magazine. Having read the April issue, I noticed a letter titled ‘training gains or pains’ which I think sums everything up that is wrong with the industry – someone who decides they fancy being a spark and expects to become a domestic installer

by doing a basic electrics course. The person concerned seemed upset that they would have to complete a test and inspection course as well, which is a fundamental part of our industry now. Apparently it cost £4,000 to complete the course – a small price to pay to work in an industry where you can earn a good wage. That said, anyone that has completed an apprenticeship will tell you that a course in basic electrics is not

enough to carry out a safe installation – this is learnt from training on the job and 3-4 years at college. Ours is one of the most dangerous industries to work in, but also at the same time one of the easiest to get into, something that Part P was supposed to improve. Yours sincerely, Steve Smith

Coiled extension leads: are they a good idea? Dear PE I was wondering if your readers could settle an argument please. I feel that using a coiled extension lead is especially stupid as it not only causes heat to build up within the inner coils over that of the insulation withstand, but because of the transformer effect, the voltage will creep down and the current

will rise, causing the end appliance to burn out. Let’s say that you have a hedge trimmer plugged into a coiled extension lead; the effect might be that the trimmer voltage will be some 50 to 70V lower while the current drawn may go higher than normal as the wattage will be the same. In either case, the higher current and reduced voltage will cause the

thermal lock-out device within the windings to fail open circuit, and the fuse (3A) to blow. Of course, if some idiot has fitted a 13A fuse while testing the lead or appliance out, they’re just asking for trouble. Yours sincerely, F Kennedy




Martin Gregg, Commercial Manager at Unitrunk asks why there are no regulations for fire testing of cable management within the electrical industry. hile fire safety has always been embedded into the design and construction of buildings through various standards and legislative controls, the events that took place at Grenfell Tower almost two years ago have, quite rightly, become a focus for examining the suitability of certain materials for use in construction or refurbishment projects. There is widespread consensus on the need for positive change.


Some legislative change has already started to happen, with certain types of ‘combustible’ cladding materials now banned on new build residential buildings taller than 18m high. It’s a start, but even this step towards learning direct lessons from Grenfell has been criticised, because high rise hotel and office buildings are exempt from the ban and the use of combustible materials for the building envelope of low rise properties remains a risk to those who live there. The Hackitt Report, published last May

following the independent review of building regulations and fire safety, highlighted the ‘ambiguity of regulations and guidance’ and called for a ‘risk-based approach’ to specification with ‘transparency of information and an audit trail’. The report acknowledges that ‘legislative change will take time’ but the question remains: why do we not already have a suitable regulatory framework in place for electrical fire safety? Moreover, with such a lack of clarity, where can the industry turn for reassurance that the jobs they are specifying now will be both


safe and compliant when any future legislation comes into force? Ambiguity As many who have worked in the construction or electrical sector overseas will tell you, the UK industry has regulatory requirements that are more robust than most other countries. Our building regulations and fire regulations are seen internationally as very demanding and the wiring regulations are now in their 18th Edition, covering a broad spectrum of electrical safety. However, despite the fact that the latest wiring regulations were clearly influenced by the need to respond to fire safety concerns prompted by Grenfell, there is still nothing within the 18th Edition that stipulates fire testing of cable management; the backbone of any commercial electrical installation and the

physical barrier between electrical cables and the building fabric. Cable management is just one of the many product categories for which there is currently no mandatory fire testing requirement, either within building regulations or wiring regulations. This leaves those with responsibility for specifying and installing cable management networks with a lack of information regarding which systems offer verified fire safety: the very ‘ambiguity’ criticised in the Hackitt Report. Despite the fact that the source of the fire at Grenfell Tower has been traced to an electrical fault, it is building envelope materials that have come under scrutiny in the wake of the disaster, rather than materials essential to the installation of building services. While we might speculate that this is due to an assumption that electrical installations carry an inherent level of fire risk – after all, more than half of fires in domestic properties are caused by electricity (Source: Electrical Safety First – 54.4% of fires in England are caused by electricity) – this is surely an argument for considering where fire safety in the specification of electrical installation materials can be improved? Safer future The programme of legislative change following the publication of the Hackitt Report has only just begun and there are certain to be more changes in mandatory standards and permissible materials still to come. So far, however, there seems to be scant attention to the fire safety of cable management systems, which is why Unitrunk has invested in independent fire


safety testing for both our cable tray and cable ladder systems, ahead of any industry requirement. For us, there may be no regulation on fire resilience but there is a moral obligation to ensure resilience is built into the design and manufacture of our products and to verify it through independent testing. Thanks to the testing, we are also now able to offer specifiers, contractors and their clients the peace of mind that comes with knowing that both our UniKlip and standard cable management systems have achieved an E90 rating, which means the cables within the system could power a lamp continuously for at least 90 minutes at a temperature of 1,000˚C – a temperature comparable to a building fire. We’re the first cable management system specialist in the UK to pass these tests and we’re now calling on the rest of the industry to do the same. For so many of us, the images of the tower of flames at Grenfell and the TV footage of distressed and bereaved residents will remain vivid for years to come. There is nothing we can do now to prevent that loss of life or devastation but we have a moral obligation to do everything we can to ensure buildings are safer in the future. Verifying the fire safety of the materials we use is an integral part of that obligation and, hopefully, it will also become a regulatory requirement one of these days, creating a corresponding commercial imperative to test for fire safety.

CODEBREAKERS JOHNNY COOKE: I found this today during a rewire on a Chinese takeaway – lead and paper lined cable supplying the first floor sockets still in use! When we inspect and test, we’re primarily looking to comply with 651.1, to determine, so far as is reasonably practicable, whether the installation is safe for continued use. By doing this, we’re evaluating work carried out to previous editions of the Wiring Regulations and comparing them with the current version of BS 7671. At some point, existing installation methods and equipment will become obsolete by either a change in our wiring techniques or the inability to repair or source spares, or both. As we can see here, we have access to live parts as the junction box (JB) lid is missing. Even if a spare could be found, the basic insulation on the conductors internal to the JB seems to show signs of degradation. We can also see live conductors have become exposed externally to the JB, just under the voltage indicator. The means of earthing the metal sheath of the lead sheathed cable also leaves a little to be desired from a modern standpoint, and wouldn’t have been to manufacturersspec, even in its day. Lead sheathed cables, such as these, were in use between 1920 and the late 1950s, so is likely to be 70 to 100 years old. To be fair the most damning factor that will make this observation unsatisfactory and point towards a significant upgrade is the failure of the basic insulation on the conductors, and them not being taken into an enclosure, which is almost impossible to rectify effectively.

MARTYN REES: New consumer unit required? Customer wasn’t sure if he needed any work doing on his mains end!!! I’ll go through the issues with this one as I see them. First of all, there’s no lid on the CU (it hasn’t been removed for testing). For that reason there is access to live parts on every circuit, therefore every circuit will attract a C1 before we start. There is no way to safely isolate or switch the CU off as the cover is missing and the danger from contact with the live terminals is high. The isolator to the left (feeding the CU) has no cover, so access to live parts here, and the fuse is visible and touchable in its carrier, so again, access to live parts. The twisted gold cable looks to have been terminated on the incoming side of a 30A carrier, so C2 there, plus no cpc for the circuit visible means a C2 again. The same situation appears for a couple of red singles which seem to be the reason for the lid being left off as the cables stop the lid from being fitted. Add to this all of the single insulated cables not taken into enclosures, cables not adequately supported, no mechanical protection, and the list is extensive. The Observations, Regulation infringements and Codes applicable to this observation would be.

Access to Live parts due to missing CU lid

416.2.2, 651.2(v), 134.1.1


Access to Live parts on CU isolator, missing lid

416.2.2, 651.2(v), 134.1.1


Unacceptable and dangerous isolation method for installation

462.1, 651.2(v), 134.1.1


Cables not adequately supported, risk of strain on terminations

522.8.5, 134.1.1


Cables not protected against mechanical damage

522.8.1, 134.1.1


Basic insulation not taken inside an appropriate enclosure: numerous circuits at CU

526.8, 134.1.1


Circuit protective conductor (cpc) is not continuous throughout the lengthof the circuit and terminated at each accessory or point of wiring

412.2.3.2, 134.1.1


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

Access to live parts: JB lid missing

416.2.2, 651.2(v), 134.1.1


Access to live parts: basic insulation degraded and missing

416.1, 651.2(v)


Basic insulation not taken inside an appropriate enclosure

526.8, 134.1.1


Basic insulation on conductors deteriorated beyond safe condition



Method and integrity of sheath earthing not appropriate



The FIs, in these cases, is to ensure all JBs, enclosures and basic insulation on conductors are checked for similar issues. If found to be lacking they will both attract a C2, in extreme cases of breakdown, they may attract a C1, if live parts are accessible.

The FI, in this case, is to ensure all circuits are checked for adequate compliance. If found throughout the installation with similar observations, they will attract a C2 code.

PAUL MACKLIN: A great find here: the client informed me he had a consumer unit change the previous day. When we finally went to check on the work this is what we found, with the consumer unit cover laying in front of the installed unit. Shocking! This is soul-destroying to say the least, and it's deeply concerning when a client has evidently been taken advantage of by unskilled or uncaring installers. As the cover isn’t in place, probably due to the way the cables have been dressed in (or not), there is straight away access to live parts, which can only attract a C1. With the multitude of cables tangled together and taped off, possibly live conductors, the best and only conclusion is to assign an FI. This is because the whole installation will need to be fully inspected. If this is domestic, the CU may well need to be metallic, which it is not. There may be a problem with division of circuits with the solitary RCD, but we can’t tell if this is the only CU in the installation; we’ll assume it is. There is a grey twin & earth at the bottom of the photo that isn’t supported or contained adequately and, being at a low level, could easily be snagged and pulled out accidentally. The Observations, Regulation infringements and Codes applicable to this observation would be.

Access to live parts, from missing CU cover

416.2.3, 526.5, 134.1.1 1


Inadequate terminations in cables which may still be live

134.1.3, 134.1.4


Single RCD on new installation may give rise to unwanted tripping


New CU installed to BS 7671:2008 (2015) (or later) in a domestic dwelling, not metallic


Twin & earth cable not adequately supported or contained



Due to poor new installation standard, the whole installation requires full inspection



C3 FI C2

RICHARD STENNER: Thought you might like this horror show for your magazine. Whoever installed this decided they didn’t need MCBs for the chiller supply!

I have to admit, that’s one of the most blatant failures to fit a protective device I’ve ever seen. The implications for serious injury from electric shock in a fault scenario are just inconceivable. Without adequate Overcurrent Protection, not only are the lives of those coming into contact with this circuit in grave danger, but there is a high potential fire risk if a significant overcurrent occurs. This kind of approach to circuit design is verging on criminal and highlights the need for regular inspections and maintenance to ensure the safety of users from both electric shock and fire. The Observations, Regulation infringements and Codes applicable to this observation would be.

The FI, in most of these cases, is to ensure the installation and modifications are inspected to confirm safety and compliance with relevant standards. The FI for the new CU not being metallic is dependent on its location and although plastic, maybe in an enclosure constructed of non-combustible material. This could either then become a no-code or a C2 respectively.

Circuit Breaker not fitted to a circuit, leading to improper fault and overload protection for the affected circuit.

132.10, 430.3, 431.1.1, 411.3.2.1, 134.1.1


The FI, in this case, is to ensure all Distribution boards in this installation are checked. If found with similar findings, they will attract a C2 code.

Technical & training



here an earth electrode provides the means of earthing for an installation, TT earthing arrangement, the resistance to Earth (RA) of the electrode must be measured to verify the earthing arrangement satisfies the requirements of BS 7671 (Regulation 643.7.2). This article looks at the requirements for providing fault protection for circuits connected to a TT system and using a proprietary earth electrode test instrument to verify the resistance of an earth electrode.

Fault protection for circuits connected to TT systems BS 7671 recognises the use of an RCD or an overcurrent protective device to provide automatic disconnection of a circuit forming part of a TT system under fault conditions (Regulation 411.5.2 refers). However as an overcurrent device may only be used where a suitably low value of earth fault loop impedance (Zs) is permanently and reliably assured, use of an RCD is preferred. Whilst compliance with BS 7671 will depend on the rating and

characteristics of the RCD, in order to achieve disconnection in the shortest possible time the resistance (RA) should be as low as practicable, and as stated in Table 1, a resistance value exceeding 200 Ω may not be stable. Where an RCD provides earth fault protection, the following conditions must be fulfilled (Regulation 411.5.3):

• •

The relevant disconnection time of Regulation 411.3.2.2 or 411.3.2.4 should be satisfied, and RA x I∆n ≤ 50 V

Where: RA is the sum of the resistance of the earth electrode and protective conductor connecting it to the exposedconductive-parts (in ohms), and IΔn is the rated residual operating current of the RCD.

These requirements are met if the Zs of the final circuit protected by the RCD meets the relevant requirements of Table 41.5 of BS 7671, see Table 1.

TABLE 1 Maximum earth fault loop impedance (Zs) for non-delayed and time delayed ‘S’ Type RCDs to BS EN 61008-1 and BS EN 61009-1 for Uo of 230 V Rated residual operating current (mA)

Maximum earth fault loop impedance Zs (ohms)









* The resistance of the installation earth electrode should be as low as practicable. A value exceeding 200 ohms may not be stable (Regulation 542.2.4 refers)

It should be noted that an RCD will provide protection against earth faults but will not detect overloads or short-circuits. Therefore, as stated in ‘Note 2’ of Regulation 411.5.2, where an RCD is used to provide fault protection the circuit must also be provided with overcurrent protection in accordance with Chapter 43 of BS 7671.

Measuring Earth electrode resistance RA Using a proprietary earth electrode test instrument the Earth electrode resistance test is conducted as follows.


Technical & training In preparation for the test the installation should be isolated, the earth electrode should preferably be disconnected from the earthing conductor which connects it to the main earthing terminal. If this is not possible, the earthing conductor must be disconnected from the main bonding conductors and other protective conductors at the main earthing terminal, to remove any parallel paths to the general mass of Earth. If such parallel paths are not removed before the measurement is made, an unrealistically low reading of the resistance of the electrode to Earth will be obtained. With reference to Fig 1, the temporary (current) electrode C2 is placed in the ground some distance away from the installation earth electrode under test. Unless the soil resistivity is very high a distance of around 40 metres is usually sufficient for this purpose. The temporary (potential) electrode P2 is placed approximately mid-way between the other two electrodes.

• •

One reading is taken with P2 in the mid-way position, and a further two readings are taken with P2 approximately 10 % of the overall distance (4 metres) on either side of the mid-way point. In principle, the instrument passes a current through the ground between the two current terminals C1 and C2. At the same time, the voltage drop between the installation earth electrode and the general mass of earth is determined by means of the voltage (potential difference) at terminals P1 and P2. The instrument then has sufficient information to calculate and display an ohmic value for the resistance of the installation earth electrode under test. Many proprietary instruments have a facility for checking the resistance of the temporary electrodes. Where the resistance of a temporary electrode is found to exceed the limit stated in the instrument manufacturer’s instructions, the resistance should be reduced to a value within the stated limit. A sufficient reduction in the resistance of the temporary electrodes may be achieved by driving longer temporary rods into the ground, or by watering the ground in the immediate vicinity of the temporary rods. The ground adjacent to the earth electrode under test must not be treated with water or brine, as this would make the resistance measurement invalid for the purpose of verification or reporting

Earth electrode testing

Determining the average value The average of these three resistance readings should then be calculated, as illustrated in the following example, and compared with the individual readings. None of the individual readings should differ from the average by more than 5 %. If they do, and there is a clear progression in the readings from one position of P2 to the next, it may mean that the resistance area of the installation earth electrode is overlapping that of temporary electrode C2. To overcome this problem, electrode C2 should be moved further away from the installation earth electrode, and the test procedure repeated.

Example When three acceptable resistance readings have been obtained, use these to determine the average value. Suppose that the following readings were obtained when testing the resistance of an earth electrode using an earth electrode test instrument: R1 = 37.3 Ω, R2 = 39.1 Ω and R3 = 41.2 Ω. The mean value is determined as follows: Resistance of electrode RA is: R1 + R2 + R3 3

= 37.3 + 39.1 + 41.2 Ω 3 RA = 39.2 Ω

This measured value should be recorded in the appropriate section of the electrical certificate or report along with the type of electrode and its location.

Gary Parker, Senior Technical Support Engineer at ECA, runs through the major changes to surge protection requirements in the 18th Edition.

SURGE PROTECTION: EASY AS 1, 2, 3 urge protection devices (SPDs) are used in electrical installation systems to protect against transient overvoltages (or voltage spikes) that can cause damage to electrical equipment by overloading components. These electrical surges can result from sources such as lightning or the switching on or off of large electrical loads elsewhere in the network. SPDs are designed to divert the excess current to earth, protecting electrical appliances and systems. With our increasingly complex dependence on electronic devices, automation and IT, in both domestic and commercial environments, the possible consequences of overvoltage damage to

vulnerable equipment and components – ranging from the loss of critical data on computer systems to the disruption of industrial plant, machinery or vital infrastructure – can be significant, costly and hazardous. What causes surges? Lightning strikes produce the largest transient overvoltage events in electrical installations, creating surges of thousands of volts lasting less than a millisecond. These can result from direct strikes, but also strikes up to a kilometre away from the installation. Man-made surges arising from switching event transients on the network, though much smaller in scale, are more frequent and can stress

electronic components, causing unplanned outages, damaging or degrading equipment – and ultimately result in equipment failure. When is surge protection needed? Chapter 44 of the 18th Edition of the IET Wiring Regulations deals with ‘Protection against voltage disturbances and electromagnetic disturbances’. Section 443 has been redrafted, removing the earlier 17th Edition’s ‘AQ criteria’ risk assessment process that considered external environmental conditions that influence lightning. Instead, the 18th Edition establishes that SPDs need to be installed by electrical contractors to protect against transient overvoltages in situations where there may be serious consequences. Effectively, the process has been simplified and the emphasis in approach has shifted from considering whether SPDs should be installed, to installing SPDs unless it’s established that they’re not required.

Protection against transient over-voltages shall be provided where the consequence caused by overvoltage could: (a) result in serious injury to, or loss of, human life, or (b) result in interruption of public services and/or damage to cultural heritage, or (c) result in interruption of commercial or industrial activity, or (d) affect a large number of co-located individuals.

If a risk assessment is not carried out, the regulation states that SPDs shall be fitted in all cases. What types of surge protection are required? SPDs are classified into three different types (Types 1, 2 and 3) according to their standard and the types of transient overvoltage they are required to handle: Type 1 SPDs Also known as equipotential bonding SPDs, these are designed to be deployed at the origin, where services enter a building or facility, and protect against major surges from direct lightning strikes. They are not, however, designed to protect sensitive electronic equipment or electrical systems from switching transients. They should, therefore, be used and co-ordinated with Type 2 devices. Type 2 and 3 SPDs These are designed to protect electrical and electronic equipment from the secondary effects of indirect lightning and against switching transients by reducing the transient overvoltage to safe levels. Type 2 SPDs can help prevent the spread of overvoltages in electrical installations, and are usually installed in distribution boards. Type 3 SPDs, which have a low discharge capacity, can be used to supplement Type 2 SPDs to provide protection for sensitive and critical loads. These SPDs should be installed close to the equipment to be protected. The use of a combination of SPD types, effectively acting as a cascaded protection system, is recommended to provide coordinated protection from transient overvoltages. Many types of SPDs are available, including combined SPDs in a single unit (such as Type 1+2+3) for simplification of installation and maintenance, and reduced cost. The correct installation of SPDs is also vital to ensure maximum protection, not only for electrical safety but also because poor installation techniques can reduce their effectiveness. For example, connecting conductors should be kept as short as possible, as this will minimise any additive voltages on the connecting cables. Full guidance on the specification for connections is available in Chapter 44, section 443 of the 18th Edition. For more information about the 18th Edition and to access a host of supporting materials and guides produced by ECA go to:

We say: The regulations say you should select RCDs to limit the risk of unwanted tripping. To ensure this, the total leakage current (which is the leakage current in the protective conductor plus the earth leakage current) should not exceed 30% of the RCD rated residual current. The best way to be sure is to measure the leakage current with an earth-leakage clamp meter, such as the Megger DCM305E. All you have to do is clamp the meter around the line and neutral conductor of each circuit, and it will measure any current imbalance – which is the leakage current – and show it directly in milliamps. Alternatively, you can clamp the meter around the incoming tails of the consumer unit/panel, then switch off all the MCBs. If you switch the MCBs back on one at a time, you’ll be able to see the leakage current associated with each circuit. The Megger DCM305E is a very good clamp meter to choose, because it can also measure AC currents up to 100A, so you’ll find many more uses for it in addition to earth leakage testing.

WHICH MAXIMUM EARTH FAULT LOOP IMPEDANCE VALUES SHOULD YOU USE? NAPIT’s Don Holmes provides us with more essential technical information. he maximum earth fault loop impedance values (Zs) in BS 7671 – or the equivalent tables in the IET On-Site-Guide (OSG) and IET Guidance Note 3 Inspection and Testing (GN 3) – are essential references when carrying out Zs tests. But what if the manufacturer of a particular overcurrent device provides a maximum Zs value for the device which differs from the corresponding value in BS 7671? Or what if the maximum tabulated Zs value in BS 7671, or the OSG or GN 3 needs to be corrected due to ambient temperature? This article will consider which maximum values of Zs to use in such circumstances.

WORKED EXAMPLE 1 An MCCB with a rated current value (In) of 32 A is connected to a circuit forming part of a TN supply system which has a U0 value of 230 V. The MCCB is required to disconnect in 0.4 seconds. Calculate the maximum Zs value.

Where: Zs = earth fault loop impedance. Ia = current causing the automatic operation of the protective device within the time given in Table 41.1. U0 = nominal voltage to Earth. Cmin = the voltage variation factor (usually 0.95). Calculating Maximum Zs values for moulded case circuit- breakers (MCCBs) Maximum Zs values for MCCBs to BS EN 60947-2 are not included in BS 7671. Therefore, manufacturers’ tables should be consulted for the rating of the MCCB to be used. Alternatively, the maximum Zs value can Supply Protection and Metering Equipment

Testing circuits for Zs values according to temperature Notes 2 and 3 at the end of Tables 41.2, 41.3 and 41.4 in BS 7671 indicate that the maximum Zs values in those tables should not be exceeded when the line conductors are at the appropriate maximum permitted temperature (70ËšC for thermoplastic). The figures in these tables can be used for design purposes. However, as the resistance of conductors tends to increase with temperature, the ambient temperature at which testing is carried out is a significant

SOLUTION From Table B6 of the OSG, the maximum measured Zs value is 1.75 Ω at an ambient temperature of 10˚C. From Table B8 of the OSG, the correction factor is 1.06. Therefore the maximum measured Zs = 1.75 Ω x 1.04 = 1.82 Ω.

Adjustment for ambient temperature When Zs tests are carried out at an ambient temperature of 10°C, the conductors being tested may be assumed to be also at 10°C. This means that the tabulated maximum Zs values of Tables 41.2, 41.3 and 41.4 need to be adjusted accordingly. For a cable having thermoplastic insulation with a maximum permitted temperature of 70°C, this adjustment can be made by simply multiplying the maximum Zs values in the appropriate table by 0.8 (Appendix A2 of GN 3). Table B6 of the OSG and Table A4 of GN 3 contain maximum Zs values for circuit-breakers based on the cross-sectional area (csa) of the protective conductor and at an assumed conductor temperature of 10°C. The note under these tables states that Regulation 434.5.2 of BS 7671 requires that the protective conductor csa meets the requirements of BS EN 60891-1, -2 or BS EN 61009-1, or the minimum quoted by the manufacturer. Table B7 of the OSG and Table A5 of GN 3 list minimum protective conductor sizes for class 3 type B and C devices with current ratings up to 40 A. This covers typical domestic installation circuits wired in twin with cpc thermoplastic cables where the cpc is smaller than the live conductors. When testing is carried out at an ambient temperature which is less or greater than 10˚C, the correction factors listed in Table B8 of the OSG or Table A6 of GN 3 should be applied to the maximum Zs values listed.

WORKED EXAMPLE 2 A circuit is protected by a 20 A type B circuit-breaker to BS EN 60898. The ambient temperature is 20˚C and the circuit is wired in 2.5mm2 twin with cpc thermoplastic cable. Calculate the maximum measured Zs.

Using manufacturers’ maximum Zs values Manufacturers may also provide maximum Zs values for their MCBs and RCBOS which are for conductor operating temperatures of 70˚C. These values of Zs are higher than in Table 41.3 of BS 7671, as they are based on the actual operating characteristics of their own MCBs. In contrast, Table 41.3 of BS 7671 gives values suitable for all BS EN 60898 MCBs and BS EN 61009-1 RCCBOs. The maximum Zs values to achieve disconnection time vary with different types of protective devices and also between manufacturers. Appendix 3 of BS 7671 recommends that wherever possible designers use manufacturerspecific data. Where manufacturers’ values of Zs for MCBs are used, they will often recommend multiplying the measured value of Zs by a correction factor, to correct for ambient temperature. For example, Schneider recommends using a factor of 0.8.

For other ambient temperatures, the appropriate correction factor should be used. Relevant circuit design criteria There will be circumstances where a designer has specified requirements which are particular to an electrical installation. The intended impedances may differ from BS 7671. In this case, the inspector of the installation should ask for the design criteria or arrange to forward the test results to the designer for verification. In the absence of such data the inspector should apply the requirements set out in BS 7671. As a NAPIT Registered Installer, you can access a wealth of technical information, guidance and advice.

“I LEARNED A WEALTH OF INFORMATION” Eager to get up-to-speed with the requirements of the 18th Edition regulations, Damien Heath of Heath Electrical (MK) took himself along to a one-day C&G training course at Hager’s Telford HQ. Here, he tells us how he got on. bviously 2019 is a big year for us electricians, with the updated 18th Edition regulations having come into force from January. Although we’ve read a lot about the new requirements through magazines like PE, it’s important for me and my business that we are qualified and compliant to the latest standards. Nowadays there is a wealth of training options available – whether it be online-only, theory-based or a


combination of both – offered by specialist training companies or suppliers who are experts in their field. To this end, Hager has been a big presence in helping contractors to understand exactly what’s required (particularly in the areas of surge/circuit protection) and is continuing to lead from the front, offering both one-day and three-day training course options (C&G certified). Because I was already qualified to the 17th Edition prior to the course, the one-day option was perfect for me, while the three-day course is specifically for those who have yet to qualify to the 17th Edition, or took their 17th Edition course some years ago. So how did it go? Firstly, this was my first trip to the Hager Academy in Telford and I must admit that I was very impressed. The company has clearly invested a great deal of time and money into this facility and it provides the perfect setting to learn from the company’s technical staff. Prior to the course, we were shown around the site, and the schedule of the day was then explained to all delegates. We were looked after extremely well


throughout the day, with stationary provided, a top quality lunchtime buffet to keep the brain and stomach charged, and refreshments available during the course. In terms of the content delivered to us, this was all theory-based with the only online element involved being the follow-up exam. I have to say that it is one of the best organised courses I’ve attended – very professional and the fact that we were all sent supporting documentation beforehand proved really useful in helping to better understand the material that was presented to us on the day.

enlitened I would imagine that the three-day course is much easier to present in terms of spreading the information across the three days, and I have to admit that it took a fair deal of concentration to take in all of the content that was delivered during this one-day offering. That said, our tutor took things at a steady speed so that everyone could understand the information given and, when questions were raised, they were answered quickly and efficiently. Essentially, the course is designed to help you feel confident when applying the 18th Edition regulations, and I have to say that I learned a wealth of new information throughout. A number of subjects were covered, including changes to the requirements for surge protection, AFDDs and RCD types, and I found the presenting style to be engaging and informative. Once completed, the all-important acid test then came in the form of the online exam, which I completed the following day. This is in multiple choice format and lasts around two hours in total. I’m delighted to say that I managed to pass with flying colours and, although a very proud moment, it wouldn’t have been possible without the help of Hager’s training experts. Although I was a tad nervous before undertaking this one-day course, all of the staff (and other delegates) that I made contact with were incredibly helpful and made the whole experience much more relaxed. The venue is fantastic, the lunch is top notch, and the learning is not too bad either! If you’re looking to get 18th Edition qualified, I’d highly recommend taking a look into the courses on offer from Hager.

LI G H T I N G G R O U P Jeff Richardson, Aurora Group’s Divisional Director for UK Trade, explains how Enlite’s AriahPro™ high bay is engineered for industry and designed to last.

High Power, Big Savings in industrial surroundings Across the UK, there are likely to be thousands of units on industrial and commercial estates in which HID’s are still in place but where an LED solution would make a worthwhile contribution to a company’s bank balance in addition to the nation’s energy saving targets. With affordable, energy-saving LED lighting designed specifically for this type of premises, it is becoming a highly attractive option for many building owners and users and one worth proposing. By replacing fittings on a one-for-one basis, there’s usually no need for a costly rewire (providing the wiring is still in good condition); and electrical work can be phased as budget and operations permit. A typical LED upgrade usually pays for itself in two years. Having remained a popular industrial solution for many years, HIDs have now been measurably superseded by today’s LED technology, in respect of both light output and running costs. A popular replacement, Enlite’s AriahPro 150lm/W LED highbays are cost effective, compact in size and reduce maintenance costs. Ideal for warehousing, manufacturing, conference centres, etc., they offer outstanding energy saving when compared with HID. Let’s compare HID’s typical energy consumption with the AriahPro. Say 12 Low or Highbay 250 Watt Metal Halide fittings are required to illuminate an industrial space and these would typically consume 3000W in total. By retrofitting with AriahPro’s 150W option, energy consumption would be almost halved. With up to 30,000 Lumens to L70 50,000 hours, the highly thermal efficient aluminium heatsink allows a low operating temperature of up to 50°C. Enlite’s AriahPro comes in 100W, 150W and 200W options. Its 120° beam angle is standard and optional 70° polycarbonate or 60°/90° aluminium reflectors are available. Engineered for industry and designed to last (it comes with a 5 year warranty), this high power LED high bay is IP65 rated, dimmable, offers 1.5kV surge protection and its die-cast housing has an IK08 impact rating for maximum protection in all environments. The AriahProHighSense comes with the same features as the AriahPro but also includes a motion sensor with adjustable detection up to a radius of 8 metres. With sensing options and the opportunity to make the AriahPro smart with Aurora’s AOne, energy costs can be reduced even further, making high industrial lighting running costs a thing of the past.

OF EXPERTISE To commemorate its centenary, MK Electric is profiling the people who have contributed towards its achievements over the past 100 years. Here, EMEA Marketing Operations Manager Emma Segelov chats to Scott Irwin, Business Operations Director, about his 30-year journey with the business and plans for the future. Scott, please can you tell us a bit about yourself ? My current role is Business Operations Director, but I started my career with MK Electric 30 years ago on a four-year technician’s apprenticeship at Southend. Since then, I’ve been involved in nearly every aspect of the business, including production and supply chain, before moving into a commercial role. I’m a huge advocate of apprenticeships, and believe my story proves you can work your way up without having to hop out of the industry.

What’s your biggest achievement? In my role as Production Manager, I was heavily involved in establishing the Logic Plus platform from a manufacturing processes perspective. It was a completely new product at the time and required implementing millions of dollars of automatic assembly equipment. This not only allowed us to produce a revolutionary new range of wiring devices, but also speed up production and improve quality overall. How has the industr y changed since you fi firrst started? Digitisation means the number of electrical devices owned by each household has increased, generating the need for USB integrated sockets to provide convenient charging. That said, not all USB integrated sockets are equal. Some incorporate robust protection against an overload or short circuit, and dynamic device recognition (DDR), which ensures optimal and efficient charging, no matter what the device. What is MK Electric doing differently in its 100th year? We have always been a premium brand, but recognise that some projects require a more value-driven

solution. We have responded to this by launching a new range known as MK Essentials to make our products more widely accessible. Designed to offer the same levels of reliability, fit and quality for which we are known, MK Essentials offers a wide range of white switches and sockets suitable for smaller budgets, without compromising on customer expectations. What advice would you give to someone who’s considering joining the industr y? Don’t restrict yourself, there are loads of opportunities in this industry and you gain important transferrable skills. I’ve been involved in nearly every area of the business, and I believe this gives me a rounded view on many areas of business operations. Also, don’t look down on apprenticeships, as they can be a stepping stone to eventually landing a senior role – many people have done it, including me.

CCTV: FROM START TO FINISH Matt Parton, Product Development Manager at ESP, offers advice on how to plan, design and install a CCTV system.

ith the UK security industry estimated to be worth £2.4bn and CCTV accounting for 50% of sales within this sector, that represents a lucrative income stream to the contractors who are willing to diversify. By utilising the skills they already possess, electricians are in a position to build business with existing customers through the adoption of CCTV as an additional product category. They can use the knowledge of this new product sector to target new customers.


Planning Possibly the most important stage of any CCTV installation is the survey. Time spent understanding what the end user and operator of the system expect will be of great benefit. Always do a thorough evaluation of the site before deciding on which products and systems will be best suited to the scheme. This will require an understanding of the specific role for the CCTV system, as well as the client’s expectations and clarifying if there are any special

requirements, such as 28 days recorded storage. Consider if it is likely that the user will require service after the installation. Ideally, during an on-site evaluation, a test monitor with a varifocal lens camera connected can be used to show the client there and then a clear example of what viewing angles and coverage can be achieved. Design Make a detailed plan of the site that is to be covered. For the purposes of security, mark on the plan the vulnerable areas such as doors, windows, access points etc. Also, mark on the plan the areas of concern or areas of interest, for example, vehicles parked on the drive. Indicate on the drawing where the cameras are to be placed to get the best coverage of all the areas of interest. Obtaining the width of field of the area of interest and the distance away from the camera will give all the information needed for selecting the correct lens type, as well as the IR specification for selecting the right camera. Mark on the drawing a secure location on the site (away from any malicious intent)

where the DVR is to be installed. Ideally, this should be an area where unhindered access to the DVR and cables/connections can be managed effectively. Mains power will be required at this location. From the site evaluation, consider where the cameras are to be positioned and how the cable will trace back to the DVR. If the cable runs are to be longer than 100m, then typically a local power supply will be required at the camera. If the cable runs are within 100m, then the power supply will typically be positioned next to the DVR. Consider whether it is possible to run the cable through the building, or whether the cable will need to be externally surface mounted. If it’s the latter, then consider discreet and secure methods of installation. Some installations may require conduit to protect the cables and deep bases for camera connections. It is also worth noting that the connection between camera and cable will not be waterproof, so if the connection cannot be made internally, the use of deep camera bases of IP rated junction boxes should again be considered. When it comes to cable access points for a CCTV installation, it will typically require



the installer to make these access points – usually with the help of a power tool. The DVR may need to be monitored elsewhere on the site, so it is important to make provisions for cable or alternative solutions to connect the DVR to a monitor. It may be that the DVR needs a network connection for remote access via smartphone/PC, so this also needs to be considered and provision made for a cable to a network access point. Consider future-proofing options such as specifying a larger system to add additional cameras at a later date, as and when the requirement arises. Fitting a surge protection socket to protect the system from grid surges, as well as additional splitters for multiple monitors, can all be considered. At this stage, it is important that the plan and

design are agreed with the client, and then the practical work can begin. Installation It is important to bench test the product or system as early as possible in order to be completely familiar with all aspects. The bench test also provides an opportunity to programme and set up system parameters prior to installation. It is best to install one camera at a time and test as you progress. At the location of the first camera, identify the cable run and, if required, make the access points with suitable tools. If drilling through external walls, drill at a slight angle so that the external access hole is lower than the internal hole. This ensures no potential water ingress will cause harm to the interior

of the building. Typically, most cable access holes will be no larger than 20mm. Fish the cable from the DVR to the camera. At suitable points, tack the cable to provide support against strain, but do not use a staple gun. Connect the cable at the camera end, then at the DVR. Apply system power and check if the picture is live. If it is, down power the system. Mount the camera and make the adjustments in order to achieve the required live view. Cable access points should be protected with cable entry plates, wall grommets etc. Clear sealant should be considered to protect the rear of the camera if the mounting surface is uneven and is exposed to moisture. Complete each installation of the cameras one-by-one, testing as you progress. Once the camera and cables are installed, the next step is to clearly label each cable at the DVR end. This will help if any system adjustments are needed or return visits to the site are required. Connect the network cable and adjust the parameters on the DVR if not set during the bench test. Test essential system functions such as recording, playback and data backup. Once the installation is complete, the client can be debriefed and issued with a hard copy of basic system operations.

Kevin Smith, Test and Measurement Category Manager at Seaward, explains why fixed appliance testing should form an essential part of your electrical testing routine. he lack of clarity on whether fixed appliance tests should be carried out with PAT tests, or when the fixed installation electrical installation condition report (EICR) is completed, means that the testing of fixed appliances is often overlooked altogether. Whilst PAT only covers individual items such as kettles, microwaves and computers, fixed appliance testing extends to any electrical equipment which is permanently wired into the building.


Fixed wiring complications Unlike PAT tests on portable equipment, which are relatively quick and simple to carry out, fixed appliances such as hand dryers, storage heaters and cookers can pose a logistical challenge due to the installation’s fixed wiring. But that doesn’t mean a simple visual inspection is enough – they should still be subjected to a full combined inspection at test intervals determined by a risk assessment.


It’s easy to take for granted that the fixed appliances that we use daily at work and home are safe, but just like any electrical item, they are subject to wear and tear. Many faults can’t be detected during a visual test, despite them being potentially very dangerous. A loose connection or damaged wire can cause a serious fire, so we really can’t underestimate the importance of carrying out thorough testing on these items, just as we do with portable appliances. What can you bear in mind? Many people who are trained and qualified to undertake PAT testing are not competent to safely isolate the supply of fixed equipment. Unlike appliances which can simply be unplugged, fixed equipment must be fully isolated and locked off before being checked with a lock-off device. It’s essential that fixed appliance and equipment testing is carried out by a competent person, in accordance with the

specific tests for a particular class of equipment. Seaward’s Apollo+ series PAT testers include programmed sequences for fixed appliance testing, making it an ideal choice for engineers who require point-to-point capabilities in their device. Since its launch five years ago, the Apollo series has been a firm favourite among users, with the Apollo+ series building on the success of its predecessor thanks to a range of new features and improved functionality, including updated software designed to speed up testing times. The Apollo+ series The Apollo 500+ and 600+ both include built-in point-to-point functionality in addition to PAT options, making it an ideal solution for engineers who are qualified to carry out both PAT and fixed appliance testing. The new Apollo+ models are also boosted by new accessories, including an external rechargeable battery pack – welcome

news for high-volume users who will now be able to recharge their devices on the go, extending their operation time. Users can also enjoy enhanced interface functionality, including customisable operator permissions, advanced search options and the ability to quickly navigate results. As with the original series, Apollo+ devices can be used alongside Seaward’s easy-to-use health and safety reporting software, PATGuard 3. How often fixed appliance tests are carried out will depend on the appliance – that’s why it’s so important to conduct a risk assessment as part of the testing process. Apollo+ series devices include risk assessment and risk-based retest calculator features, allowing engineers to easily determine a risk-based suggested retest period in line with the IET 4th Edition Code of Practice. Another new feature is Seaward’s QR code label format, supported by the

Seaward QR Data Viewer App, which gives end users like facility managers the ability to quickly access device data and appliance details during PAT audits. Seaward webinars For people who want to learn more about electrical testing, Seaward offers a range of free webinars aimed at helping engineers improve their skills and keep up-to-date with the latest information. The on-demand sessions cover topics such as legal requirements, industry guidance and common practice, how to perform risk assessments, how to test fixed appliances and how to improve safety standards. We believe our customer care is second-to-none and this is just one of the ways we can help those working in the electrical testing industry. From helping them choose the right tester, to offering specific training for topics such as fixed appliance testing, our webinars are ultimately about sharing our knowledge to

keep people safe – a responsibility we take very seriously. We regularly update our PAT equipment and it is important that we give our customers a chance to keep up to date with the latest technology.

CHARGING CHOICES T GARO Electric talks PE through charging solutions for every site and setting in order to harness the full range of opportunities of the EV revolution. he last couple of years have seen a major escalation by governments to incentivise electric vehicles (EVs) as an important component of their strategy to meet emission targets. As car manufacturers reduce and withdraw their diesel and petrol ranges, the expanded choice of electric and hybrid models is now a realistic option for the masses. Consequently, EV Dharging infrastructure is rapidly developing to support this evolution. For businesses and retailers, the benefits of installing EV charging stations are far-reaching. The presence of charge points encourages visitors to choose your location and spend more time there. As an employer, attracting and retaining top talent can be a challenge, hence the increase in employee benefits programmes. Adding EV charging options

to company parking spaces is one more benefit that enhances the reputation and attractiveness of an organisation.

What’s out there? GARO Electric’s comprehensive range of EV charging stations is ideally suited to fulfilling this demand. The company is part of the GARO Group, which includes Norwegian and Swedish operations. Our Nordic counterparts are market leaders in the region and have completed numerous high profile installations, including Volvo Sweden’s R&D facility, Swedavia Airport Car Parks, Sweden’s Green Highway, McDonalds Sweden and multiple energy utility companies and service stations. GARO Electric is now bringing this extensive experience, innovation and expertise to the UK market, offering a premium quality, complete range for the local market. Over the last 12 months, the company has completed installations across a number of high profile organisations, including Facebook, Musgraves, Abbott Laboratories, Boston Scientific and more. The entire EV charging range is approved for OLEV grants. There are charging solutions for institutions, workplaces, offices, shopping centres, car parking spaces, service stations and more, while GARO’s Product Development team is continually developing and enhancing the charging range to meet the future requirements of customers.

Which chargers are appropriate for which settings? For charging at work or home, a wall mounted charger is the most common option. With GARO’s GLB range, a hybrid EV can be fully charged in around three hours, and a pure electric EV in around six hours.

For public locations, car parks and larger workplaces, a faster, more robust option is appropriate. Built to withstand the elements, GARO’s LS4 range of chargers can charge a pure EV in just three hours. Its features include premium design, smart metering, connectivity and enhanced safety features. All charging points are fitted with cloud billing and reporting functionality to ensure total and accurate charging control for operators. A unique load balancing function allows the charging station to adapt to the demands of the user’s system. The entire range has been built with robust, quality materials and smart technology, including load balancing, connectivity and metering. A three-year warranty is standard across the range.

PROTECTION, AS STANDARD Andy Douglas, MD at Timeguard, asks whether your RCD protection is up to standard. t’s now two years since the latest British Standard for RCD protection and, while there has been the usual period of grace to run down stocks of older devices, surely it’s time to ensure your customers get the full benefits of the latest thinking on their safety? That’s where the new Valiance+ range of RCD-protected switched sockets and spurs comes in. Timeguard has undertaken a complete redesign, adding the latest generation of componentry throughout as well as the reassurance of compliance with the latest safety standards. Both end-user safety and long-term reliability are improved.


The standard Valiance+ is fully compliant with BS 7288:2016: ‘Specification for residual current devices with or without overcurrent protection for socket-outlets for household and similar uses’. This latest standard was published in November 2016, revising and updating BS 7288:1990. The main visible sign of compliance with the standard is that there is now a dual-flag indication system to show whether the power is live: RED – ON, or Green – OFF when the RCD is tripped. However, ‘under the bonnet’, other changes add up to greater reassurance for users. They mostly relate to EMC resilience, with more stringent testing to ensure products can withstand years of


use and electrical or physical abuse and RF interference. While it is still legal to sell and install devices certified to the older standard, one could ask as to who would want to compromise on safety regulations when newer compliant devices are on the market? The range The latest Timeguard Valiance+ range offers a complete range of 1 gang and 2 gang RCD switched sockets in both active and passive versions, so you can decide whether the power is automatically restored to the device when the power is restored (essential for freezers etc.) or if it remains isolated until manually reset (essential for power tools, etc. with exposed moving parts). There are white plastic and rugged metal clad variants in both 1- and 2- gang and a choice of three styles of RCD switched fuse spurs, as well as Weathersafe enclosed sockets for outdoor use. Why bother with RCD sockets? An RCD wiring accessory or residual current device is a life-saving device, designed to provide added protection for people against the risks of electrocution. If, for instance, someone cuts through the cable when mowing the lawn or touches a faulty appliance indoors, RCDs specifically detect earth leakage. This could of course be leakage

through the body of a person who is grounded and has accidentally come into contact with live components or cut wires. RCDs are designed to disconnect quickly enough to mitigate the harm caused by such shocks. A miniature circuit breaker (mcb) at the consumer board is an automatically-operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Installers have increasing knowledge and ideas on where the extra protection provided by RCD sockets and RCD spurs should be installed, although of course any socket that might conceivably supply power for outdoor use should have built-in RCD protection. Just make sure the RCD sockets you fit are meeting the latest safety standards as well as looking good for installation anywhere.

WHICH FAN FITS THE PLAN? he ‘Building Regulations Approved Document F – Ventilation’ sets minimum flow rates that an extractor fan installed in a wet room should be able to deliver when correctly installed. The accompanying Domestic Ventilation Compliance Guide 2010 details “Best Practice” installation methods. The minimum airflow rates are as follows:

T ● ● ● ●

Toilets = 6 l/sec Bathrooms = 15 l/sec Utility rooms = 30 l/sec Kitchens = 60 l/sec (30 l/sec in kitchens when the fan is installed adjacent to the hob – this is also the minimum flow rate expected from a ducted cooker hood).

Excess moisture, often created when these rooms are in use, can result in condensation, damp, and ultimately mould developing if left unchecked. By having a properly performing extractor fan in these rooms, excess moisture is removed and the conditions allowing mould to form are largely eliminated. However, there isn’t a one-size-fits-all approach regarding the type of extractor fan that you should install.

What type of fan? Having considered the application of the ventilation required, it is important to select the correct type of fan to meet the requirement fully. Axial Fans are ideal for through the wall, ceiling and short run of ducting applications. Whilst providing high performance from a slim profile, they work against limited back pressure so are recommended for use with flexible ducting not exceeding 1.5m in length, with a maximum of two 90˚ bends. Mixed flow fans for wall and ceiling combine the convenience of the size of an axial fan with the performance of a small centrifugal fan, making them ideal for short-to-medium duct runs. Centrifugal fans are quiet, powerful and suitable for wall and ceiling applications. They work well against system resistance, making them the perfect choice for efficient performance for longer duct runs.

An approved ventilation system is required in the toilet, bathroom, shower, ensuite, utility room and kitchen for all installations that are notifiable work to Building Control. Here, the team at Airflow outlines which extractor fan you should install.

Installed performance It’s not sufficient to just fit any fan. The selected fan should perform efficiently by extracting the minimum flow rate as required by the latest Building Regulations. The number of bends and the length of duct attached to the fan will create resistance to flow that must be overcome to ensure adequate extraction, known as ‘installed performance’. Fans should also be positioned to give an optimum flow of air through the whole room and, to avoid pockets of residual air, they should be mounted as high as possible, well away from primary heat sources such as gas water heaters and boilers. To optimise ventilation of a bathroom, it may not be beneficial to rely on a window to supply the replacement air. This is subject to the proximity of the fan to the window. You must also consider the location of planned or existing door and window openings, as well as sources of odours, stale air or condensation. Undercutting of doors and use of trickle vents is required by the Building Regulations to allow air into the room.

CP ELECTRONICS STIRLING HEALTH AND CARE VILLAGE CP Electronics has helped provide dementia-friendly solutions, in accordance with research published by the University of Stirling, at Stirling Health and Care Village. CP Electronics installed its RAPID system, which offers a centrally controlled scene-setting solution that allows staff to manually control light levels in corridors. At night time, staff are able to dim the lights to 50% of their full output. The system can also dictate lighting to dim to 50% if there is no movement after 15 minutes, and to a further 25% after another 15 minutes – this is thanks to the use of 81 Passive Infrared Sensors (PIRs). Brian Hedley, Area Sales Manager for CP Electronics, said: “Balancing the wellbeing of patients and the needs of staff was key to this project. Together, with the help of FES Limited, the lighting control systems succeeded by creating a comfortable and practical environment.”

IM DIVISION AC ENTERTAINMENT TECHNOLOGIES The northern sales centre of AC Entertainment Technologies, based in Leeds, required a general upgrade and a change of use to several areas. To carry out the work on the centre, comprising of warehousing and offices, MHE (Halifax) was chosen as the preferred contractor. The company in turn selected various products from the Installations Material Division for the switchgear and cable management. The mains sub-distribution board was supplied from Proteus Industrial Switchgear’s BX Range, with all the associated steel cable tray and trunking from Tamlex Steel Cable Management. Complementing the overall aesthetic, LED downlighting was also fitted directly into the cable tray. Mick Habergham, Company Director for MHE, said: “I cannot think of any other company that could have met the needs and expectations in this way over such a diverse range of products. By teamwork with IMD and ourselves, we have a happy client which, ultimately, is what counts.”


Paddington Library in central London now benefits from Sylvania’s SylSmart solution. Working on behalf of Westminster Council, Sylvania provided a complete lighting upgrade at the library. SylSmart uses the latest technology to detect human presence and natural light, adjusting the light levels to only emit exactly what is needed. Sylvania gained council funding for the project after demonstrating the payback period of under five years including maintenance, or under eight years on energy alone. With this system, energy savings of up to 87% are possible, and green building certificates, such as BREEAM, can be met. Jonathan Willis, Service Delivery Manager at Paddington Library, commented: “We needed a dependable and efficient lighting system, without detailed surveys carried out before installation. With the library open seven days a week, any downtime for maintenance is very disruptive to users, so we had to keep that to a minimum.”

VENT-AXIA AQUARIUM SUMP ROOM Vent-Axia’s Lo-Carbon Svara fans have helped tackle severe condensation in an aquarium sump room. The private aquarium, located at a home in Lancing, West Sussex, contains 2,000 litres of water and is home to a variety of marine fish and a living coral reef. Svara has three speed models, including a boost speed of 30l/s that is activated by the humidistat which reacts to sharp changes in humidity. This helps control damaging humidity levels that can lead to condensation and mould and the associated health risks and building damage. Ryan Meredith, who owns the house in Lancing, commented: “The fans have been running for a few months now and I am pleased to say that I have zero condensation and no signs of any mould. The room is covered in hygienic plastic sheeting and, in the past, the moisture would be running down the plastic.”



Super Rod has launched an innovative pry tool to ensure safer electrical isolation when working on appliances or installations, as PE reports.

PRY AND MIGHTY he Super Rod Pry is the invention of David Beech, a Gas Technical Engineer. After 15 years of working in the heating industry, he became frustrated by coming across multiple damaged fuse carriers and being unable to remove the fuse for safe isolation, or to inspect the fuse rating. So, David set about developing a prototype design and is now working in partnership with Super Rod, who will market the product. Designed and developed with installers in mind, the Super Rod Pry is a new tool which has an angled pry tip that can easily access and remove fuses from fused spur carriers located in hard-to-reach locations, such as close to a work-top, cupboard or appliance. In these situations, installers would normally reach for a standard flat blade screwdriver to release the fuse, however, this isn’t a great solution and it often results in the fuse carrier getting damaged, which means replacing the


fused spur socket, adding unnecessary time and cost onto the job. With the Pry, this problem can be a thing of the past. As well as getting into places where a screwdriver can’t, the tool also has important safety benefits. On the underside of the unit, there’s a handy fuse retainer where installers can place the fuse for safe keeping while they work on the appliance or installation. By removing the fuse and safely retaining it, the likelihood of the power being accidentally reconnected – and the risk of electric shock to the installer – is significantly reduced. Made from a high strength, durable polymer material, the Pry has excellent insulation properties, as well as longevity. To ensure users keep it close to hand while they work, the Pry also has a key ring hoop so it can be easily added to an installer’s key chain.

Insert the angled Super Rod Pry tip into the fuse carrier

Apply pressure to the Super Rod Pry tool to release the fuse carrier Remove the fuse, check for the correct rating and retain the fuse within the clips on the underside of the tool

If required, the fuse carrier can be locked off by inserting the Super Rod Pry tip

WORKWEAR THAT REALLY WORKS For this review, product tester Ronny Wendlandt slips into two of Snickers Workwear’s latest garments. ooking smart when arriving at a customer’s site is so important these days, as is the need for comfortable and safe workwear that meets the requirements of the end-user. To this end, Snickers’ vast range of workwear has always been a favourite of mine, so I jumped at the chance when I was given the opportunity to try out a couple of the brand’s latest garments.


1. SNICKERS FLEXIWORK RIPSTOP HOLSTER TROUSERS The fit Having purchased many pairs of various workwear trousers over the years – ranging from engineering blues to jeans – I must say that this pair of Snickers trousers felt very different. Lightweight, comfortable and sleek, they provide a good fit around the waistline and pockets galore. Users will benefit from plenty of well-positioned belt buckles, including three along the back (with a large one in the centre of the back), two along the sides and two along the front to help secure the belt. The pre-bend knees are positioned perfectly and take to the inserts with ease. Day-to-day use From day one I got tremendous use from these trousers, and found the pockets to be an absolute god-send during first-fix, where you run cable and fill your pockets with clip, cable cutters and your trusted hammer hanging through the loop, or second-fix (or test and inspection) where you require more tools and hands-free options. When working (whether it’s bending down, up and


downstairs or kneeling), these trousers hold their shape thanks to the lightweight stretch material combination without pinching the skin in the back of your knees or on the inner thighs. The tough Cordura material is excellent at keeping dirt and dust away. Safety and protection These trousers really are built for safety, with the Cordura material and bent knee pockets combined with the option for knee pads and the garments’ stretch material giving flexibility and choice to the user. Reinforced material, tough stitching and strong zips are all hallmarks of the proven workmanship that goes into Snickers’ gear.

Would I recommend? Yes and yes again! These are a top quality pair of trousers that are fit for any trade professional who is after safety, comfort and flexibility.

2. SNICKERS FLEXIWORK FLEECE The fit Lightweight, comfortable and in keeping with the latest fashion trends, the Snickers FlexiWork fleece hoodie is designed to keep you warm and stylish on-site. I found the garment to be really well proportioned; not too long but long enough to cover your lower back when reaching out. There’s also plenty of room provided for extra space from additional clothing. The hoodie is breathable and provides three outside pockets and inside pockets with a strong zip. Thumb holes are featured at the end of the sleeves, giving the option of holding the sleeves in place and keeping your wrist warm. Would I recommend? Once again, it’s a ‘yes’ from me! The FlexiWork fleece hoodie is well made, modern looking and boasts a good quality fit and design. In my opinion, this is a great companion for any tradesperson.

The cordless machines provide equivalent power to a 1,000W corded grinder. They are up to 35% more powerful and give up to 100% longer runtime compared to predecessors. The angle grinders also include automatic safety systems; for example, KickBack Control immediately shuts down power to the motor if the disc is suddenly jammed. Drop Control does the same as soon as a dropped tool hits the floor. The X-LOCK system is a tool-less alternative to conventional accessory attachments. Simply bring the accessory and grinder connecting surfaces into contact and press; a ‘click’ sound tells you they are firmly locked. To remove a disc, just flick a lever on the grinder. Changeovers can be completed in five seconds – which is five times faster than normal.

Vent-Axia Lo-Carbon PoziDry Compact Pro PIV Offering a new way of thinking about Positive Input Ventilation (PIV), Vent-Axia’s Lo-Carbon PoziDry Compact Pro can combat condensation and mould in problem properties without a loft. At 200 x 200mm, it’s half the size of conventional boxed PIV units, meaning it can fit in the smallest spaces. A removable inner cartridge makes for simple installation and maintenance. The PoziDry Compact Pro features a foam back plate which weighs less than 100g, ensuring there is no need for installers to lift a heavy metal box above head height to mark drilling holes. Plus, with two inlet and outlet positions, the PoziDry Compact Pro can be installed horizontally or vertically in 16 orientations. Ultra-low sound levels and increased energy efficiency are guaranteed thanks to its anti-vibration EPP body which makes the unit condensation resistant too; noise levels are as low as 11dBA. 66 June 2019 PROFESSIONAL ELECTRICIAN

Van choices heating up this summer Hot on the heels of the 2019 CV Show, we look at some of the latest van options available to electrical businesses. If you’d like to see a promotional video related to each of these vehicles, simply type in the that corresponds with each item.

MITSUBISHI OUTLANDER PHEV COMMERCIAL With a revised electric powertrain and efficient new Atkinson-cycle petrol engine, the 2019 Mitsubishi Outlander PHEV Commercial saves businesses money in a multitude of ways. The UK government’s Plug-In Van Grant reduces its on-the-road price by over £7,000 and – being an Ultra-Low Emissions Vehicle – also means it can operate in London’s Ultra-Low Emission Zone (ULEZ), saving a further £24 per day compared to an older diesel van. Its 28 miles of pure electric range (WLTP) also drastically lowers running costs compared to a petrol or diesel-burning vehicle. In comparison to a pure electric commercial vehicle, the Mitsubishi Outlander PHEV Commercial also minimises the downtime associated with seeking out charge points and recharging during the day, and for longer journeys, it offers the backup of an efficient petrol engine. More importantly, it can be configured to save its battery until it reaches a ULEZ or re-charge itself en route to any urban area, ensuring any journeys within towns and cities are made silently and cleanly, improving air quality for everyone.

FORD NEW TRANSIT SPORT OPTIONS The new 185PS version of Ford’s enhanced 2.0 litre EcoBlue diesel engine makes the Transit Custom Sport van one of the most powerful ever, heading up a range of three Transit Sport van models with their signature twin sports stripes. In addition to a 9% power increase and 415Nm of torque for more responsive performance, Transit Custom Sport van customers benefit from a connectivity boost with the introduction of FordPass Connect on-board modem technology. The new Transit Connect Sport van, revealed last year at the IAA Commercial Vehicle show in Hannover, Germany, is also now available, and features the upgraded 120 PS 1.5-litre EcoBlue diesel and six-speed manual transmission. The compact Transit Courier Sport van completes the line-up.

Did you know... Hearing assistance systems are called for in many public places under the Equality Act, BS8300, the Care Standards Act and Part M1 of Building Regs? Furthermore, did you know failure to provide a suitable hearing assistance solution can amount to discrimination against a disabled person? Of all the assistive listening systems available in the UK, hearing loops are by far the most popular. They work by transmitting amplified sound to hearing aids allowing hearing aid users to hear more clearly. C-TEC manufactures the UK’s widest range of hearing loops including:

NEED ANSWERS TO YOUR 18TH EDITION QUESTIONS? OUR TOP 10 TECHNICAL ARTICLES COULD HELP! We have a whole host of technical articles available on our website for all your electrical needs, as well as a dedicated 18th Edition section to answer any lingering questions surrounding the new regulations. Check out the following articles if you’re looking to shore up your 18th Edition knowledge:

Top Product Awards, NAPIT’s EICR Codebreakers publication has been updated to include the latest changes to the 18th Edition regulations. Gary Fisher of Lougar Electrical is our resident book-worm for this one as he tries it out for size.

1. 18TH EDITION: WHAT ARE THE REQUIREMENTS FOR OVERVOLTAGE PROTECTION? With the introduction of the 18th Edition, the decision-making process for inclusion of overvoltage protection in electrical installations has changed. Dave Enefer, Devices Product Manager at Crabtree, takes a look at the latest requirements for overvoltage protection.


3. SURGE PROTECTION: WHAT ARE THE REQUIREMENTS FOR DOMESTIC DWELLINGS? Regulation 443.4 requires protection against transient overvoltage to be provided where the consequence caused by overvoltage could result in serious injury or loss of human life, interruption of public services and/or damage to cultural heritage, interruption of commercial or industrial activity or could affect a large number of collocated individuals. Here, the technical experts at Europa Components offer advice on installing surge protection devices in domestic dwellings.

4. EV CHARGING: DO YOU HAVE THE RIGHT TEST EQUIPMENT? Vehicle charging points can now be protected by either an RCD type B or an RCD type A and appropriate equipment that ensures disconnection of the supply in case of a DC fault about 6mA. Brendan Beaver, Sales Manager of Metrel, looks at why changes to the 18th Edition should have minimal impact on testing, as long as you’re armed with the right equipment.



9. BEYOND ESCAPE ROUTES: NEW REQUIREMENTS OF THE 18TH EDITION Key amendments to regulations on fire safety, particularly regarding escape routes, need to be given careful consideration. Gary Parker, Senior Technical Support Engineer at the ECA, looks at the fire safety ramifications of recent changes to the 18th Edition regulations 5. ARC FAULT PROTECTION: REQUIREMENTS & RECOMMENDATIONS Did you know that the wiring regulations require protection against arcing? Simon Rowlinson of Wylex delves into the 18th Edition regulations to explore whether Arc Fault Detection Devices (AFDDs), although defined as a ‘recommendation’, are essentially ‘mandatory’ in certain scenarios.

It’s key that electricians and contractors get trained and upskill their knowledge to ensure that their installations are compliant. Deepak Sharad, Category Manager for Final Distribution at Schneider Electric, explains why you need to take a diligent approach to your 18th Edition procurement process.

10. CHALLENGES OF THE 18TH EDITION With the implementation of the 18th Edition now a few months old, Michael Kenyon, Electrical Specialist at Bureau Veritas, considers the impact of the amendment and what it means for the electrical industry.

6. SELECTIVITY: WHEN IS IT REQUIRED? The 18th Edition of BS 7671 has changed what has been known for many years as ‘discrimination’ to ‘Selectivity’. The technical team at Stroma take a look at changes to the 18th Edition regarding Selectivity between overcurrent protective devices and what this means for installers.



8. RESIDUAL CURRENT DEVICES – WHERE SHOULD THEY BE USED? RCD is a generic term that covers a range of residual current devices including RCBOs and RCCBs. Primarily, an RCD is selected so that its residual operating current rating is appropriate for its intended purpose, whether that be for fault protection, additional protection or for protection against fire. The experts at NICEIC give best practice guidance and advice.

ONLINE ORIGINAL: MEET LITTLE MISS ELECTRICAL Every month, PE Online runs a number of ‘exclusive’ features and technical articles, offering you fresh, original content. Proving particularly popular during the months of April and May, we profiled a female electrician who is making great strides in the sector. athleen Cockin runs hers own business, Little Miss Electrical in Huddersfield. Having trained to become an electrician while working in an office as a legal executive, she has since switched to working in the trades full-time and hasn’t looked back. Last year, Cathleen got in touch with NICEIC, asking for an extra helping hand in her career. She explains: “I had got into property development with my partner and he suggested that I train as an electrician so that I could re-wire our properties. I really enjoyed it, and loved being out on-site. It certainly beats being stuck in an office all day. “I qualified as a domestic electrician, but I wanted to be able to offer Electrical Installation Condition reports (EICRs) to landlords and estate agents as well. At the time, I didn't have the right qualifications so I got in touch with NICEIC as I was aware of its campaign to support women in the industry.


“I couldn’t quite believe it when they offered to put me on their Inspection & Testing Course. Now I can confidently complete the report and offer a wider range of services.” When quizzed about her thoughts on more females entering the electrical industry, Cathleen says: “With the electrical industry being such a male-dominated sector, I was nervous about going into it. I thought I wouldn’t fit in because I’m a female. “I’ve never been one to let other people’s opinions stop me doing what I want, so I just cracked on with it, and got the total opposite response. “Yes, there were a few narrow-minded comments here and there, but the majority of people on the course said how refreshing it was to see a female for a change. I’ve got so much positive feedback and support from everyone. Customers, wholesalers, training centre, friends and family are all so kind and supportive. “It makes such a big difference knowing people are behind me in what I do. They really want me to do well.” She continues: “What I love about this industry is that there is always an opportunity to learn new skills. I get such a buzz from working on a job, powering it up and having it actually work. “Now that I am qualified to complete EICRs, my next plan is to get my head around data cabling, smart home systems and alarms. After that, I’d like to take on a few more apprentices. “I’ve just taken on a young girl which is great and has really helped me out.”

Cathleen concludes: “Eventually, I’d like to have a couple more female electricians and have a few ‘Little Miss Electrical’ vans buzzing around the area. I’ve been able to bring in enough work to need more staff so it would be great to create more jobs – especially for the girls.”

CALLING ALL FEMALE ELECTRICIANS! We want to share your journey and experiences to help attract and support women in the trade. If you would like your story featured on the PE website and/or magazine then please email:

IDEAL Introducing the In-Sure Box To make the installation of electrical conductor enclosures safe, fast and simple without the need for any tools, IDEAL has launched the new In-Sure Box. The In-Sure Box is designed for use with In-Sure Push-in, In-Sure Lever and SpliceLine wire connectors, making it maintenance-free and suitable for installation of an electrical junction in an inaccessible location, such as behind plasterboard or under a floor. As the In-Sure Box complies with the BS 5733 maintenance-free accessory standard and BS 7671 wiring regulations, it provides safety while removing the need to fit unsightly or awkward access panels. Plus, it avoids damage to finished surfaces which would then need to be expensively reworked or repaired. Uniquely, the new In-Sure Box has four cable entry points, allowing up to two cables each, meaning that it can be used either as a cable entry from one end or an ‘in-line’ configuration, for applications such as cable splices or lighting spurs. It is designed to accept most common flat and round cables with an overall diameter of 3mm to 8mm and can accept up to six individual connectors. A wide range of helpful features enable domestic electrical installers to benefit from quicker, simpler installation in any application with the In-Sure Box. By combining Push-In, Lever or SpliceLine wire connectors with the patented In-Sure cable grip system, no additional tools are needed to secure the cable. This makes installation fast, easy and fuss-free, even when working in awkward environments, such as up a ladder or in a confined space. This video gives you more details about how the product works, and how you can save time and money on-site.
