LATEST NEWS READ THE FULL STORY IN THE NEWS SECTION OF

SPARKS-MAGAZINE.CO.UK APPRENTICES DRIVING BUSINESS GROWTH Apprentices are more than worth the money it costs to train them, new research shows. The Electrotechnical Skills Partnership (TESP) said companies that recruit apprentices can see a return on investment in year two at higher charge-out rates, and in year three at the lowest rates. The research found that by the end of year four, apprentices created a net total benefit of between £11,400 and £56,700. TESP chair Ruth Devine said: “Although it is a commitment, which can be daunting to small businesses, investing the time and resource into apprenticeships will ultimately drive business growth.”

TRADE SKILLS 4U OPENS NEW CENTRE IN COVENTRY Trade Skills 4U is to open a new training centre at Westwood Business Park in Coventry. The electrical training provider has been training electricians from across the country since 2005 at its centres in Crawley, Warrington and Leeds. Students can now book on to a range of courses including City & Guilds diplomas, Domestic Installer Packages and Inspection & Testing. Carl Bennett, chairman and founder of Trade Skills 4U said: “I am extremely excited with the opening of the new centre. We have conducted a lot of research in the area to ensure that this is the perfect location to run our courses from.”

COLLEGE GETS EQUIPMENT BOOST FROM SCHNEIDER ELECTRIC When Schneider Electric contacted Warrington & Vale Royal College’s Dave Love, he didn’t expect to receive ‘more than £90,000’ of products for students. But that’s what happened! Now, thanks to this donation – which arrived on eight pallets – the students have access to the most up-to-date equipment in the industry. Schneider Electric had been contacted by the e5 group who had visited the college earlier in the year. Deepak Sharad of Schneider Electric said: “I was so happy that we have been given an opportunity to provide such equipment to the students.”


ELECTRICAL CONTRACTORS SHOW FALL IN REPORTABLE ACCIDENTS The accident rate among electrical contracting businesses fell in 2018. New figures show the rate of RIDDOR-reportable accidents fell to 164 per 100,000 employees, with no fatalities reported last year. The rate of specified (major) accidents was also lower than in 2017. The main causes of injury were falls, slips and trips and there was one reportable injury caused by electric shock. Steve Brawley, chief executive of the Joint Industry Board, said: “The rate of reportable accidents in our industry continues to fall, and it means that the rate of these accidents is now, remarkably, only slightly more than 10% of what it was in 2001.”

ELECTRICAL ENGINEERING STUDENTS WIN HS2-INSPIRED COMPETITION Electrical engineering students from Birmingham have won a competition based around the development of HS2. Five first year Level 3 students from South & City College Birmingham were tasked with redesigning Birmingham New Street Station and improving the onward journey for passengers travelling through the city. The students were given an insight into HS2 at Birmingham’s High Speed Rail College and after pitching their proposal to a panel of expert judges were awarded first place in the Fast Trackers 2019 programme. The winning students will now get the opportunity to work with mentors from Network Rail and Mott MacDonald.

SOMERSET SPARK ANSWERS DIY SOS A Somerset-based electrician has praised local tradespeople for helping out on an episode of DIY SOS. Matt Francis, of NICEIC-registered M Tech Ltd in Bridgwater, was among the trades who helped create a two-storey extension for a family of five in Weston-super-Mare. He led the electrical design and installation work on the nine-day project after volunteering his company’s services at a registration event earlier in the year. “There was a bit of pressure to get it done in time,” said Matt. “But everyone got involved and there was such a good buzz on site.” The episode is due to air on BBC One this year.

APPREN OF THE YEAR 2020

Do you have what it takes to compete against the best electrical apprentices in the country?

The regionals heats of the SPARKS Apprentice of the Year competition take place between January and March, with Level 2 and 3 students from more than 80 colleges taking part across eight regions – the South West, South East, North West, North East, Midlands, Wales, Scotland and Northern Ireland. SPARKS Apprentice of the Year is now in its 11th year and we’re excited to be including Scotland as one of our regional heats for the first time. The winners of the regional heats will go on to compete at the grand final, which will take place at Schneider Electric’s impressive Innovation Hub in Coventry. As well as the prestige of winning the competition, there are prizes worth up to £10,000 up for grabs, with every competitor getting a certificate for taking part.

The SPARKS Apprentice of the Year grand final will take place at Schneider Electric’s impressive Innovation Hub in Coventry.

10

Last year’s winner was Ben Kidner, a third-year apprentice at Bridgwater and Taunton College. Ben qualified for the final as the best runner-up but despite being the self-confessed underdog, he impressed the judges and did enough to win the overall competition. Ben’s advice to those thinking of entering this year? “Definitely take it up, it’s a big confidence booster and I’ve seen the results. I’ve seen the improvements since day one, especially with the extra hours you do practising.” Sean Miller, electrician channel programme manager at Schneider Electric, said: “We are proud to be helping the electricians of tomorrow as they start out on their journey. It’s always great to see the apprentices working with our products throughout the regional heats and the final, as the standard of work is very high.”

If you think you’ve got what it takes to follow in the footsteps of our previous winners, head over to www.sparks-magazine.co.uk to sign up. We can’t wait to see you all when the competition gets underway in the New Year.

BUSINESS LUKE SKILLS: WICHARD

PART 2

Following on from his interview in the Summer issue of SPARKS, Luke Wichard tells us how he makes the most of marketing, personal and business growth and the online world to better himself and his business, My Trusted Electrician.

SPARKS Magazine: What’s the best way to maximise your time? Luke Wichard: That’s easy - plan. Write down a list of what needs doing and what needs doing first. I use a mixture of apps but the best is Trello. Chuck your ‘to do’ items in there the second they pop into your head. SPARKS: How do you market your business? LW: I use leaflets, local community magazines, Google Maps listings for my website, Checkatrade, Facebook and my van signage to reach local homeowners. It’s important to advertise in multiple places. SPARKS: How do you set goals and go about achieving them? LW: Imagine where you want to be when you retire. Have a finishing line to focus on. Create small achievable milestones to reach each year. SPARKS: How do you continue learning? LW: I love YouTube. You used to only get one shot at college before the real world, but now we have all this information at our fingertips and it’s free. I drive a lot and have

“It’s important to advertise in multiple places”

discovered that audiobooks are a perfect opportunity to learn. If you drive for only one hour a day, that’s five hours a week which you can be learning. SPARKS: How do you use the internet to boost your business? LW: I use Facebook to interact with customers and provide helpful content. Hopefully, they’ll think of me first when they need an electrician. I use YouTube for quotations. For example, if I’m quoting to rewire a kitchen then I will attach a YouTube video about rewiring a kitchen with my quote. SPARKS: What is one tip you would give to your younger self? LW: Learn how to run a business and how to market. Don’t assume that it’s not important and that you will pick it up as you go along. Even if you’re good at your trade it’s not enough to make the phone ring.

ELECTRICAL WHOLESALERS

WHAT TO LOOK FOR WHEN CHOOSING A SUPPLIER “Some Electric Centers offer evening deliveries or overnight lock up collection”

HOT TIP AGREE A SET OF DISCOUNTED TRADE TERMS WHEN YOU SET UP YOUR ACCOUNT

A good wholesaler should be able to provide the branded products you trust. There are also some great own label products available such as those supplied by Electric Center as part of its Acel range. They are made by top manufacturers and clients can’t price-check them online.

> PRICING

A

Price is always a factor in any purchase. Sit down with your electrical wholesaler to discuss the type of products you will need and agree a set of discounted trade terms when you set up your account.

> TRUSTED PRODUCTS

> KNOWLEDGEABLE AND HELPFUL STAFF

You may hear electricians talk about the importance of being able to ‘fit and forget’ – once you’ve completed a job, you don’t want to be called back to fix or replace products you’ve installed.

You may need to rely on the staff at your wholesaler for a bit of help every now and again. They may also be able to advise on the best products for a job or suggest viable alternatives.

s an installer, it’s important to have a wholesaler you can trust. But what should you look for when it comes to choosing the ones you want to work with?

> STOCK AND DELIVERY You want your wholesaler to have a good range of equipment and accessories in stock – with the ability to source and supply the things they don’t have quickly and efficiently. Some Electric Centers open early in the morning or late into the evening to meet customer needs and some offer evening deliveries or overnight lock up collection. Electric Center has 118 branches across the UK and prides itself on providing great customer service, flexible delivery options and quality products. It is the gold sponsor ofthe SPARKS Apprentice of the ear competition.

THE POWER OF LIGHTING Interact Pro with Philips Interact Ready luminaires has been installed in the Innovation Room at TATA Steel’s headquarters in North Wales.

“TATA Steel now delivers its most innovative systems through lighting”

> COST EFFECTIVE The new system has provided the company with a quick and cost-effective connected lighting installation. It provides effective lighting control to allow the creation of an impactful ambiance for the customers who visit to learn about the latest innovation in the steel industry. “Our innovation room is an important space where we showcase the best of our work, so it is important that we have an equally sophisticated, connected lighting system but one that our employees can operate with ease,” said Jason Wilkes, electrical engineer, TATA Steel.

> QUICK INSTALLATION Interact Pro uses a wireless network to connect luminaires, sensors and switches. This means that it is much easier to install than many existing

lighting control systems and doesn’t require additional cabling, making the process swifter. Users can quickly set up the connected lighting system via the Interact Pro app. The Interact Pro system has been so well adopted by TATA Steel’s employees that the light switches put in place are no longer needed – meaning that light is only used when required and reduces overall energy consumption. “From early consultations we knew Interact Pro with Philips Interact Ready luminaires was a system that would help TATA Steel make an impact with customers to reflect its innovation,” said Stuart Jolley, trade and specification director for Signify in the UK and Ireland. “We look forward to continuing the partnership in the future to continue to deliver the most innovative systems through lighting.” LIGHTING

> ENERGY SAVING The Interact Pro system has put TATA Steel employees in control by letting them tailor light levels according to their requirements. It allows them to customise scenes and schedules through easily tapping the Interact Pro app, facilitating the productivity and well-being of employees. Also, it ensures that the lighting in the room is only used when it is needed, significantly reducing energy costs. Register for training at www.interact-lighting.com/pro I AU TU MN 2019 I SPA RKS

STARLITE

Hub-free smart lighting designed with installers in mind

“Choose from 16 million colours or 64,000 shades of white”

T

amlite Lighting has partnered up with Wiz Connected to launch the Starlite Connect range of downlights, bulbs and LED tape. Starlite Connect lighting products sync directly to phones, tablets and voice assistants – including Google Home, Amazon Echo and Siri – without the need for an additional gateway or hub. You can connect quickly and simply using wifi or Bluetooth, meaning users can get creative with their home within 30 seconds.

> EASE OF INSTALLATION Starlite Connect downlights, bulbs and tape have been designed with installers in mind. No smart system training is required to set up the Starlite Connect system. With a simple product design and no hub to install, sparks can fit the luminaires in the same way they fit standard fixtures.

The commissioning can then be done post-installation by the user. Starlite’s 24-hour tech support means that customers can raise any commissioning queries with them, not with the contractor. This means electricians can get into the smart lighting industry without the need for smart lighting training, providing the ultimate ‘fit and forget’ solution.

CABLES PROVIDED BY BASEC

DOS & DON’TS

Even cables that are sourced responsibly are at risk during initial delivery and installation. During this phase, they will be subjected to movements, stresses and strains - and if these exceed the cable design limits, damage becomes a strong possibility.

“Maximum cable tension and sidewall pressure limits can both cause damage if exceeded when pulling cables”

> BEND RADIUS – ARMOURED CABLES Bend radius is a key consideration, particularly for armoured cables and for higher voltages of 11kV or more. It should be communicated by manufacturers and passed on by suppliers to the installers. Maximum cable tension and sidewall pressure limits can both cause damage if exceeded when pulling cables. To prevent this, cable installation routing should be closely assessed, and several rollers or guides used at any bend points. > BEND RADIUS – SCREENED CABLES With screened cables such as BS 7629-1-rated fire alarm types, the minimum bend radius must be maintained to ensure fire integrity. Kinks in the screening or overtight entry into accessories may compromise fire performance. > CABLE PULLING Problems can occur where cables are pulled in two directions from a common mid-point. This approach can cause significant damage to a cable that cannot twist freely during installation, or where loops of cable introduce twists.

Here are some top tips for a clean, trouble-free installation: > CABLE DELIVERY AND CUTTING TO LENGTH Safe handling of cable starts with the supplier, often a distributor or wholesaler. Manufacturers will deliver cables on an appropriately-sized drum or reel, loaded under controlled factory conditions. Cutting the cable to length, and redrumming onto an often-smaller delivery drum can result in over-bending if the drum belly diameter is too small.

Avoiding cable torsion when pulling is important, and is largely addressed by using rotating pulling heads and a suitable cable pulling sock. Tension built up around each bend will propagate back down the cable, causing issues nearer the drum. Competent and experienced cable installation teams, using the correct equipment including tension-monitored winches, pulling socks, and a generous quantity of rollers and guides, should experience fewer problems while ensuring a trouble-free installation.

SAVE TIME

WITH SWIFT

The Swiftclip, which forms part of Legrand UK’s Swifts cable tray range, has been designed with speed in mind. Requiring no tools during installation, the Swiftclip not only significantly reduces the number of components required, but also ensures cable management installation times of at least four times faster than a nut and bolt solution.

> FIVE SIMPLE STEPS: Connecting the Swiftclip couldn’t be easier. Here, Mark Williams, lead marketing manager for Legrand’s cable management business unit, demonstrates an installation in just five simple steps:

> STEP ONE: INITIAL SET-UP

01

Ensure the cable tray supports are placed in the relevant location before you begin.

> TOP TIP

When designing a cable management installation, cable ladders, cable trays and their supports should be strong enough to meet the total load requirements of the cable management system. Ancillary items such as light fittings or junction boxes should be taken into consideration as well as the cables and any predicted future additions.

> STEP TWO

02

Place a straight length of cable tray across the supports. Ideally the joint should be a quarter of the span of the cable tray from the support for maximum strength. Place the next straight length of cable tray across the next supports and position the coupler centrally over the tray joint.

36

SPARKS I AU TU MN 2 0 1 9 I CAB L E M AN AG EM E N T

> STEP THREE

03

Place the Swiftclip between your thumb and index finger and insert the joggled head through the aligned tray and coupler slots.


> STEP FOUR

04

Pass each leg of the Swiftclip through the tray and coupler slots, starting with the leg nearest to the tray wall.

Repeat process on the other side of the tray, fitting the clip in the opposite direction. Ensure the head and feet of the Swiftclip are clamping through the tray and coupler and that the Swiftclip spans across the joint.

> TOP TIP Swiftclip can be used not only to connect length to length, or length to fitting, but can also be used to secure the bed of the tray to the supports (trapeze hangers/cantilever arms etc).

> STEP FIVE: SWIFTCLIP INSTALLATION COMPLETE

05

The Swiftclip is compatible with the existing Swifts medium (MRF) and heavy duty (SRF) cable tray systems, is load-tested to BS EN 61537 and provides earth continuity without the need for additional components. In addition, the innovative cable management component is available for internal pre-galvanised and external postgalvanised applications.

FIRE SAFETY WITH FIREFLY Nick Hayler, technical and product QA manager from cable management manufacturer MarshallTufflex, explains why product selection is vital to ensuring compliance. > STAY UP-TO-DATE

> THE FIREFLY RANGE

Falling, hanging and trailing cables present a serious risk in the event of a fire, not only as they may hinder occupants trying to evacuate, but also for the emergency services entering the building. The updated BS 7671:2018, Regulation 521.10.202 - which came into effect January 2019 - now requires cables to be adequately supported against premature collapse in the event of a fire. This applies throughout the installation, and not just in escape routes.

Fire clips are required to ensure that cables are held up in the event of a fire. But what should you be looking for when choosing fire clips? Marshall-Tufflex has recently extended its Firefly range, in line with the updated requirements, so it includes clips that are suitable for use on its entire range of PVC-U trunking systems. The clips fix to walls or ceilings and, with their spring-loaded design, are quick and easy to install. Thoroughly tested,

“The Firefly fire clips are fire resistant above 1000°C for up to 120 minutes”

the Firefly fire clips are fire resistant above 1000°C for up to 120 minutes, and feature rounded ends to prevent damage to cables and injury to installers. The range includes both internal versions that can be installed within the trunking prior to cable installation and externally fitted variants for a simple retrofit to ensure an existing installation is compliant.

AM2

WHAT’S IT TO YOU?

Get help preparing for your AM2 from NET

D

id you know, at the end of your electrical apprenticeship you’ll need to take the AM2 or AM2S test, or the FICA in Scotland, before you can become fully qualified? What does this mean? Think of it as similar to a driving test – you spend weeks or months learning how to drive, then the driving test is where you put everything into practice and you are marked against strict criteria.

“The AM2 covers installation, fault– finding, safe isolation, inspection & testing”

“The AM2 and AM2S are 16-hour tests split over two-and-a-half days” > IN-DEPTH ASSESSMENT The AM2 and AM2S are just like this – it’s an in-depth assessment where you have to carry out specific tasks to show what you have learned during your apprenticeship. The whole test is around 16 hours long, split over two-and-a-half days, and it’s broken down into different sections such as installation, fault-finding, safe isolation and inspection & testing. Strict exam conditions are in place during the assessment, so this means no electronic devices or getting help from anyone else. You’ll be monitored by an assessor, who

will be marking your work as the day progresses. Once you pass the assessment, it’s one of the final pieces of the puzzle to completing your apprenticeship and becoming a fully qualified electrician.

HOT TIP USE NET’S SELF-ASSESSMENT CHECKLIST TO ENSURE YOU’RE READY TO TAKE THE TEST

> AM2 OR AM2S? Your training provider will tell you which assessment you’ll be taking: the AM2, or AM2S. This just depends on which type of apprenticeship you’re following.

It’s really important that you don’t take the test until you’re 100% ready. The NET website has a selfassessment checklist that lists everything you need to do. Use it during the last few months of your apprenticeship, talk to your employer and training provider and make sure you’re comfortable with all areas of the test so you’re fully prepared before booking.


TOOL UP FOR

SUCCESS

“Be prepared to pay a little extra for tools that will protect your health & safety”

Advice from Bosch Professional on choosing your first set of cordless power tools. > RULE ONE

COMBI

Make safe choices by insisting on professional quality. Your tools will last longer, do a better, faster job and give you fewer problems. And remember: your health is your greatest asset. Be prepared to pay a little extra for tools that will protect it.

A great all-rounder – and the first power tool in any professional electrician’s bag. Combines drilling and screwdriving functions with an impact drill mode – which you can activate to hammer through hard materials like concrete. Check out the Bosch GSB 18V-21 Professional Combi.

> IMPACT DRIVER

> DUST EXTRACTOR

> OSCILLATING MULTI-CUTTER

Another must for electricians. Specialised for screwdriving but good at drilling in wood too. Applies rotational shocks – perfect for removing damaged or stubborn screws, and for driving screws through hard wood. More compact than a combi or drill driver, it’s great in cramped spaces and easier to hold in place – with no danger of kickbacks.

Using power tools generates dust. Never assume it’s harmless. Dustrelated illnesses permanently damage health and shorten lives. Remove it close to its source with a purpose-designed vacuum cleaning and filtration system.

Electricians have multiple uses for this. Its side-to-side motion allows accurate, highly controlled cutting, grinding, scraping and sanding – often in confined spaces where a rotating tool can’t reach.

Check out the Bosch GDR 18V160 Professional Impact Driver with its class-leading price-toperformance ratio.

See the Bosch GAS 18V-10 L Professional Dust Extractor, for wet and dry use, which maintains maximum suction over long periods.

Go for one with the Starlock system, which gives firmer blade attachment, better performance and a wider range of applications. The Bosch GOP 18V-28 Professional MultiCutter, with snap-in accessory change, is your best choice.

Use a combi or drill driver instead for: larger drilling diameters and harder materials; driving long, thin screws into timber; and precise setting of screw tightness.

“An impact driver is great in cramped spaces”

> BATTERIES FIRST! Before it’s too late to change, start building a set of compatible 18V tools – so you don’t need different batteries and chargers for each one. For more information visit:

> USER FRIENDLY

> DETECTION MODES

UNIVERSAL MODE:

The tool is very user friendly with clear visual and audible signals and a high contrast display. It enables even beginners to accurately locate cables and to find ideal spots for electrical installations.

The D-Tect 120 detects up to 120mm and can be used to meet a variety of electricians’ application needs through its three detection modes. The illuminated buttons enable users to choose between the operating modes, increasing the accuracy for different application scenarios. The detection depth varies within the different detection modes in order to optimise accuracy.

The default detection mode easily identifies metal, live wires and water filled plastic pipes. It covers the majority of existing wall scenarios and applications. If the detected material is unknown then this is the mode to use.

With the object tracking function, you can easily avoid costly mistakes. The D-Tect 120’s clear display screen indicates the positioning of detected objects behind surfaces through its informative directional arrows offering vital guidance for new electricians.

“The object tracking function helps you avoid costly mistakes”

DRYWALL MODE: A mode optimised for materials such as plasterboard and wallboard. This is the best mode to detect wooden studs but is just as accurate for metal, live wires and plastic pipes.

CONCRETE MODE: Optimised for concrete and other homogeneous materials. Use when searching for rebar.

> CENTRE FINDER FUNCTION When an object is located, an audio signal will be heard as well as a visual display signal. This is useful when locating objects and when identifying safe areas to drill. The orientation arrows that appear on the display point you to the centre of wires, water-filled plastic pipes, wooden studs and more.

> SPOT MEASUREMENT FUNCTION

> DUAL POWER SOURCE

The innovative radar technology enables spot measurement for precise detection even in the most compact of spaces – there is no need to move the tool back and forth, as results are displayed as soon as the tool comes into contact with the surface.

The D-Tect 120 has a dual power source, being operable by either alkaline batteries or a 10.8/12V lion battery, from the Bosch Professional Power Tools range - bringing versatility to detection.

FREE SAFETY KITS FOR TRAINEES IN SCOTLAND

The very first item you should own as a trainee electrician is a safety lockout kit. The kit costs around thirty quid and could save your life. Get used to using a lockout kit early on.

T

oo many electricians are injured or killed each year because they have not safely isolated the circuit whilst working. Safety lock-out kits should be used as an integral part of the safe isolation procedure. Even if your employer doesn’t use a lockout kit, you should. > TRAINING TRUST

SECTT and Electrical Safety First are taking a lead in supplying these to all 3rd stage Apprentices and Adult Trainees in Scotland. SECTT chief executive Anne Galbraith is an advocate for electrical

safety at work. She said: “I cannot stress enough the importance of working safely at all times, to protect the apprentices, our colleagues, and the members of the public. “The kits will be provided to apprentices and adult trainees from the Shetland Isles to the Borders, studying at 21 approved centres across Scotland. Apprentices and adult trainees should become familiar with these lockout kits as these are the same kits that are used when sitting the Final Integrated Competence Assessment (FICA), which is the AM2 equivalent in Scotland.

“Even if your employer doesn’t use a lockout kit, you should!”

“Over 650 trainees are being supplied with free lockout kits by SECTT and ESF. Worth £30, the kit will help the electricians ensure that electricity is turned off (and stays off) until electrical work is safely completed. This process is a safety fundamental and essential in helping to avoid a serious or fatal electric shock.” “Adopting safe working practices and procedures is essential, particularly for this industry,” said Phil Buckle, chief executive of Electrical Safety First. “The kits promote safe working as an ingrained habit. At some point in their career, that could make the difference between life and death.”

CHECKING EARTH LEAKAGE CURRENTS

Megger on its DCM305E earth leakage clampmeter

“Exceeds latest safety design standards”

> SAFETY IN MIND

T

he DCM305E is perfect for identifying and measuring the earth leakage current in a circuit where the RCD (residual current device) keeps tripping out unexpectedly. The measured result will quickly identify whether the earth leakage current present is excessive, causing the RCD to trip, or if the RCD itself is over-sensitive or faulty.

> EFFICIENT AND VERSATILE Specially designed to check earth leakage currents, the DCM305E is an efficient and highly versatile instrument. The clamp features an autoranging display with the option of six manual ranges – 6 mA, 60 mA, 600 mA, 6 A, 60 A and 100 A – with a minimum resolution of 0.001 mA on the 6 mA range. The device’s upper range also enables TRMS AC current measurements up to 100 A. Additionally, this clampmeter vastly improves measurements on circuits with harmonics/electric noise on the cables using a low pass filter of 50/60 Hz.

“Quickly identify if the earth leakage current is excessive”

Safety is of the utmost importance and with that in mind, the DCM305E exceeds the latest safety design standards IEC1010-2-32 and EMC requirements through a series of safety features that provide you with a safer working environment. Other key functions include the ‘data hold’ feature, which aids in measurements where there is a problem with accessibility or poor lighting, and the automatic power off feature that extends the battery life.

> EARTH LEAKAGE Earth leakage is electric current that finds its way to earth via an unintended path. There are two types of earth leakage – intentional and unintentional. Unintentional earth leakage results from faulty equipment or insulation, whereas intentional earth leakage is exactly that – a consequence of equipment design. Examples are IT equipment and fluorescent lighting systems, which often produce a small amount of earth leakage even when operating correctly. Check out uk.megger.com

THE 18TH EDITION AND INSPECTION & TESTING WHAT YOU NEED TO KNOW! The 18th Edition of the Wiring Regulations, which came into full effect this year, contains lots of big changes, but also several subtler changes. As an installer you need to be fully up to date with these changes, to ensure you can continue to undertake tests and inspections safely, efficiently, and in accordance with the Wiring Regulations. > PART 6, REVISITED Part 6: Inspection and Testing, contains some of the more extensive changes in the 18th Edition. It has been completely restructured to align the Regulation numbers with the CENELEC standard (CENELEC is the body responsible for European standardization in electrical engineering).

By Gary Parker, senior technical support engineer, ECA

> IS MORE COMPLEX RCD TESTING NEEDED UNDER THE 18TH EDITION? There is a note in Regulation 643.8 that now states that RCDs up to 30 mA can be tested at a current equal to, or higher than, five times their rated residual operating current. There is also more emphasis on different types of RCDs, particularly where there may be waveform distortions. EV charging and solar PV are good examples of this. Note that in some instances, these RCDs, often known as Type A, Type B or Type F, may not be compatible with some older models of RCD test instruments.

“As an installer you need to be fully up to date with these changes”

The model forms of documentation in Appendix 6 of BS 7671:2018 have also been modified, albeit only slightly, with the biggest change being in the Minor Electrical Installation Works Certificate; seeing some content moved to highlight the ‘presence and adequacy of earthing and bonding arrangements’. Regulation 643.6 has introduced a new requirement to verify polarity at the origin, where relevant, before energisation. This is something that most contractors have done, but is good to see in the Regulations.

> DO NEW CERTIFICATES NEED TO BE USED? There are subtle changes to the 18th Edition test certificates, but this goes for all the forms. As such, any work being done in accordance with the 18th Edition commencing on or after 1st January 2019 should be, and should have been, certificated using 18th Edition model forms.

CONSIDERED TE ACHING YOUR TRADE?

If your phone is anything like ours then it’ll be full of apps, some of which you don’t even use. SPARKS takes a look at the latest apps to help you fill your phone with something useful.

Due to the expansion of our provision we are seeking candidates for the following Construction Trade positions: • LECTURER - PLUMBING • LECTURER - PAINTING AND DECORATING • LECTURER - ENGINEERING We would also like to hear from experienced and knowledgeable trade professionals in Carpentry and Joinery, Electrical Installations and HGV Motor Vehicle who are looking to develop their career whilst passing on their valuable skills to the next generation.

MyHOME Up App by Legrand The MyHOME Up app works as part of the MyHOME UP home automation system. Essentially, it is a remote alternative to a wired control panel. Once the MyHOMEServer1 has been powered up, all actuators and dimmers will be working within minutes. The contractor then opens the app in ‘installer mode’ and all devices connected to the server will be ready to link to a function on the app. The same app can then be downloaded and used by the homeowner to remotely control and manage synchronised lighting, climate, audio controls and more. Free to download on iOS and Android.

HERE’S WHAT YOU’LL NEED :

• Recent experience of working in the industry • Up to date knowledge of the subject/vocational area • Ability to inspire, motivate and raise the aspirations of learners • Full driving licence and use of vehicle for business purposes • A Level 2 in English and Maths or the ability to demonstrate competence at this level through diagnostic testing • A minimum Level 3 NVQ in a relevant trade • A teaching qualification OR the willingness to obtain one An additional recruitment and retention payment may be available to the right candidate dependent on skills, qualifications and experience. If you would like to have an informal conversation about any of the roles or would like to arrange a visit to the College to meet the team, see our workshops and get a better understanding of the courses we deliver then please contact the Human Resources Team on: 01530 836136 or staffrecruitment@stephensoncoll.ac.uk


EXERCISES We’ve been lucky enough to collaborate with electrical expert Mike Davies, who has been in the industry since the 1970s. Mike became a qualified electrical engineer after completing an apprenticeship when he left school at 16. He became a college lecturer in 1980 after completing a Further Education teacher training qualification. Now retired, Mike works as a self-employed lecturer and training consultant.

ELECTRIC CABLES The following questions require you to study the relevant sections of Units 202, 203 and 204 of C&G 2365-02 and Unit 305 of C&G 2365-03 or EAL equivalent. For each question decide if the answer or statement is true or false and consider why.

STATEMENTS

Q1

Electric cables are designed to carry voltage.

Q2

The specified size of an electric cable is the cross-sectional area (c.s.a.).

Q3

Copper or aluminium is the material used for the conductors in electric cables.

Q4

The greater the c.s.a. of a cable, the shorter its circuit length has to be.

Q5

Cables must be suitable for the environment in which they are going to be installed.

Q6

The resistance of a conductor decreases with increasing length and increases with decreasing cross-sectional area.

Q7

The first stage in calculating a suitable circuit cable is to determine the design current of the circuit.

Q8

The current rating of a cable is halved when a BS 3036 type protective device is used.

Q9

The voltage drop of a chosen cable must be determined before the cable is considered suitable.

Q10

Table 4D2A and 4D2B are the tables to be consulted when calculating the correct size of twin and earth cable to be installed.

Q11

The maximum current rating and voltage drop of a 6mm² twin and earth cable when clipped directly to a surface (Reference method C) is 47A and 7.3mV/A/m.

Q12

A 25mm² single-core thermoplastic non-armoured cable without sheath, installed to method A and supplying a single-phase resistive load, has a maximum voltage drop per ampere per metre of 1.80mV.

ELECTRIC CABLES The following questions require you to study the relevant sections of Unit 203 of C&G 2365-02, Unit 302 of C&G 2365-03 and Unit 309 of C&G 2357-13 NVQ or EAL equivalent. It is a good idea to review the basic principles of conductor and insulation resistance when considering electric cables.

RESISTIVITY Electric cables consist of the insulation and the conductor. The conductor is usually made from copper, but can be aluminium where larger cross-sectional areas may be required. Two facts apply to a conductor: a) The longer the conductor, the greater the resistance. b) The greater the c.s.a., the lower the resistance. This can be shown in a simple diagram:

r1

c.s.a.

Length

If conductor length is doubled, the conductor resistance is doubled: r1

r1

R total (Rt) = r1 x 2

If the c.s.a. is doubled then the resistance will be halved r1 r1 End view

Side view

}

= r1 2

Worked example: Let (r1 = 1Ω) If the conductor is doubled in length then R total (Rt) = 2 x 1 = 2Ω If the conductor length is increased five times then Rt = 5 x 1 = 5Ω

Q1

Identify the British Standard series that applies to cable conduit systems.
