TECHNOLOGICAL INNOVATION | SPARKS

“THE NEXT GENERATION OF ELECTRICAL PROFESSIONALS CAN CARVE OUT A PLACE FOR THEMSELVES IN THE INDUSTRY AND OFFER REAL VALUE TO CUSTOMERS.”

I

t has never been more critical for electricians to stay on top of the latest products, trends and techniques. Those entering the profession must understand the advantages of specific technology, and the fundamentals of the modern home, to be competitive now and in the future.

The opportunities which technology presents to the electrical industry are clear - greater flexibility, control, efficiency and reliability, as well as easier installation and maintenance.

GAINING COMPETITIVE ADVANTAGE

Working with the right product can provide the edge in a competitive market.

Consumer units such as Easy9 Compact offer flexible wiring options, allowing installers to deliver circuit protection in any new build or retrofit project with minimal intrusion.

Those who fail to understand their products will find themselves working harder than their competitors to achieve similar results. Suitable products enable electrical contractors to work smarter, instead of harder.

TECHNOLOGICAL INNOVATION Technological innovation is fundamental to improving our world, and the electrical industry is at the forefront of this. What does this mean for you, the next generation of electrical professionals?

MEETING CUSTOMER DEMANDS

Modern customer demands mean products need to be customisable, flexible and meet specific environmental needs. A compact size and a low-profile aesthetic mean that electrical installations remain inconspicuous. By offering bespoke solutions to customers, electrical contractors can transform businesses, saving them time, energy and money.

GETTING UP TO SPEED

The next generation of electrical professionals can carve out a place for themselves in the industry and offer real value to customers. Meeting these ever-changing needs of consumers will be a prerequisite for success, for providing confident consultancy to meet specific needs.

SPARKS | WHAT’S IN MY TOOL BAG?

“I NEVER THOUGHT I WOULD GET THIS EXCITED ABOUT BUYING NEW TOOLS! IT’S ALWAYS A GOOD FEELING WHEN YOU ADD TO THE COLLECTION.”

WHAT’S IN MY TOOL BAG? STEPHANIE WARD

When Stephanie Ward needed some extra money, Stuart, an electrician and her future father-in-law, came to the rescue. He needed a gofer, she had a week off from her retail job… and so her journey started!

12

WHAT’S IN MY TOOL BAG? | SPARKS

HERE’S STEPHANIE’S TOOL BAG AND FAVOURITE GO-TO TOOLS!

MULTI TOOL

IMPACT DRIVER

CABLE CUTTERS

ARMOUR SLICE

RETHREADING TOOL

LONG-NOSED PLIERS

It’s one of my favourite tools. It’s super adaptable and I use it for cutting through pretty much anything including plasterboard, floorboards and around tiles using a diamond tip. It’s also got a sanding function.

Essential for working on armoured cable, it slices through the armour sheathing and scores the strands much more accurately than a hacksaw, leaving a neater edge ready for the gland.

MOST INTERESTING

This is my multi-functional test meter.

A lot of my work includes testing and fault finding and this is a tool that can help me determine what the issue is so it can be resolved!

With three torque settings, my impact driver always makes light work of fixing and removing screws. It doubles up as a drill for making small holes in plasterboard and wood using the spade bit.

This is especially important on renovation and repair work - how many times has this got me out of a situation where the thread of a lug shears?!

These are a great tool, that’s why I have two sizes. The mini ones I have on me all the time, they’re useful to cut and strip most cables. I get my standard ones out when I’m terminating larger cables.

When you need to get to a cable at the back of a board or other hard-to-reach cables these come into their own - the extra length nose means most cables can be grabbed.

TOP TOOL TIP

Always have a separate tool bag so you don’t have to break your back lugging the whole kit around everywhere.

MOST USEFUL

I know it’s boring, but a range of insulated screwdrivers. I always keep my 3.5, 5.5 flat head and PZ2 on me at all times.

SPARKS | INTERVIEW

INTERVIEW SPARKY NINJA David Watts, aka SparkyNinja, has twenty years’ experience in the industry and is a founding member of the e5 group. He now runs a training company and works to try to improve training standards and help apprentices online.

“THIS INDUSTRY HAS FAR MORE TO OFFER THAN YOU MIGHT THINK AS AN APPRENTICE.” SPARKS: Where do you want to be in five years’ time?

SPARKS MAGAZINE: Why did you decide on this trade?

SN: I want to be in a position where electricians are trained and practising to higher technical levels and the industry takes more action in safeguarding the public from the risks of incompetent electrical workers. Whether my part in achieving that is just by providing quality electrical training, getting more directly involved in the EngTech Elec strategies or pushing forward with the argument for a licence to practise, remains to be seen.

The next 18 months are going to be interesting.

SPARKY NINJA: I did well at school but I had no idea what I wanted to do as a career. My dad and grandad were electricians, running a family firm. They said if I took on an apprenticeship I would learn life skills that would ensure I was never without work. They were right.

SPARKS: What advice would you give someone just starting out?

SN: This industry keeps reinventing training routes, qualifications, registration schemes and card schemes - it can often appear daunting when first starting out. Fundamentally, the science behind electrical systems and how it’s utilised doesn’t change too often. So keep going back to the basics with your technical knowledge and things won’t appear too confusing over time.

electricians can start using them and take a more sensible approach to condition monitoring of electrical systems.

SPARKS: What tool could you not do without?

SPARKS: What’s the best thing about your job?

SN: A thermal imaging camera.

SN: The feedback I receive from electricians after they have taken part in my training. My training is tough and heavy in technical content, but it is delivered in a way that makes electricians understand it more easily.

SPARKS: How does social media affect your business? What do you use it for?

SN: Social media has helped to build a solid reputation, which has given me the opportunity to take SparkyNinja forward as a training company.

SPARKS: Which bit of new technology are you most interested in?

SN: Power monitoring equipment. It’s becoming more affordable, meaning more

14

SPARKS: What would you be doing if you weren’t an electrician?

SN: I would probably be in the emergency services for a full time job and training to develop video games on the side.

SPARKS: Who has been the biggest influence on your career and why?

SN: Most probably my dad. He started to lecture at a local FE college and asked me to get involved. From that point, training has been my main focus.

EV CHARGING

Electrical Lecturer Leeds College of Building

With the ban on Internal Combustion Engine vehicles set to come into effect in 2030, the demand for EV chargers is set to soar. Things we must assess prior to installing an EV charger include the location of the charger, the location of any necessary earth electrode and the adequacy of the existing installation.

1. A BS1363 socket that is installed as a dedicated EV charging socket outlet shall be identified by a label with the words: Answer: 2. Charging equipment installed in an outside location shall have a minimum IP rating of?

Answer:

WWW.SPARKS-MAGAZINE.CO.UK

TOP TIP

When deciding the location of the EV charger to be installed, remember to find out not just where but how the client parks their car. You wouldn’t want to get to the end of your install only to find out your lead doesn’t reach the client’s charging inlet!

“IF THERE IS...

A NEW TEST, LIKE ELECTRICAL VEHICLE SUPPLY EQUIPMENT (EVSE) TESTING, YOU CAN UPDATE THE FIRMWARE FOR FREE.”

DOTS MAKE TESTING EASIER A multi-function tester is a staple piece of kit for any electrician but Metrel’s multi-function testers are a bit different. Brendan Beaver, manager of Metrel in SW London, explains why.

ADAPTABLE

Metrel’s multi-function testers are based on dot matrix screen technology, like your smartphone, rather than using liquid crystal screens. This makes them more adaptable and updateable.

EVSE TESTING

Of course the testers deliver all the normal electrical tests you need, like non-tripping loop tests in a good repeatable fashion.

But if the testing requirements change or there is an improved measurement method, for example the introduction of a new test, like Electrical Vehicle Supply Equipment (EVSE) testing, you can update the firmware via the internet yourself for FREE.

16

MULTI-FUNCTIONAL

We believe that your tester should be truly multi-functional and be at the centre of your business, allowing you to certify your work quickly and simply, helping out when you need a quick reminder how to make the connections, and offering more, like SPD testing, lux measurement, cable tracing and power quality. All this and more is available on the MI3152XC full colour touch screen tester now.

AFFORDABLE

If your pockets are not that deep yet, take a look at the MI3125BT or the MI3100SE, a more conventional looking MFT but with a big heart. They are both rechargeable, monochrome testers, but offer help screens and internet updating ability, so you’ll never be forced to buy another tester to keep up.

ELECTRIC POWERTRAINS COME IN TWO FORMS: PLUG-IN HYBRIDS (PHEV) AND PURE ELECTRIC (BEV).

ATTITUDES ARE CHANGING… FAST

Fast-changing consumer opinion is influencing how companies operate.

Research from the GlobalData Survey has revealed that 58% of customers would support businesses that are trying to have a positive impact on the environment. This coupled with government incentives and emissions targets means that many consumers not only prefer businesses that demonstrate environmentally conscious operations, but actively avoid those that don’t.

PHEVs AND BEVs – YOUR OPTIONS

Electric powertrains come in two forms: plug-in hybrids (PHEV), which couple a traditional petrol engine with a rechargeable battery, and pure electric (BEV).

THE BIG TWO FOR EVs: RANGE & CHARGING

Range and charging time are the two big considerations when switching to electric.

A SUSTAINABLE FUTURE ROOTED IN HISTORY The e-mobility buzz was sparked in 1970, and an impressive zero-emission vehicle line-up is emerging, according to Volkswagen Commercial Vehicles.

Ensuring you have means to charge and the powertrain can achieve the mileage you need between charges is vital to understanding if a BEV or PHEV is right for you.

THE FUTURE COULDN’T BE CLEARER

The future for commercial vehicles is brighter and greener than ever – and because of that Volkswagen Commercial Vehicles is planning to extend its electric product line further. The ID BUZZ concept has been previewed ahead of launch in 2022, to demonstrate the brand’s commitment to a sustainable future, while showcasing the blend of practicality, luxury, and cutting-edge technology of future EVs.

CORDED POWER – CORDLESS FREEDOM Work is easier without an electric cable holding you back, but are cordless tools strong enough for every task? What about the really tough jobs that need large angle grinders, saws or rotary hammers, for example?

Thanks to BITURBO, described by Bosch Professional as its most innovative and powerful range of 18V battery-powered tools ever, cordless convenience now goes much further.

Their revolutionary technology brings you the same power and performance as corded tools rated up to 1800W.

GAL 18V 160C, Worlds Fastest Charger

are much more efficient and powerful, run longer per charge and have up to twice the lifespan. BITURBO motors boost power even further with their maximised airflow, which reduces resistance, and their high-strength neodymium magnets.

A New Dimension of Power For maximum effect, the BITURBO motor is paired with an 8Ah or 12Ah ProCORE18V battery. Designed to drive and maintain the higher currents needed for power-hungry applications, these advanced batteries feature Bosch’s COOLPACK 2.0 technology. This uses intelligent heat management to optimise efficiency, for greater power and runtime, while extending battery life by preventing damage from overheating.

GBH 18V 36 C, Cordless SDS Rotary Hammer

Feel the Extreme BITURBO tools will turbocharge your working life and give you a sensation of extreme power.

They achieve that by combining two key elements: a high-performance brushless motor and the high-powered Bosch ProCORE18V Professional Battery System. These two parts have been engineered to work perfectly together and maximise each other’s performance.

Meanwhile, the BITURBO motor makes full use of ProCORE18V’s potential. A tool powered by one highly compact, lightweight ProCORE18V battery can match some competitors using two batteries.

Discover the BITURBO Brushless range and more in the Bosch Professional World.

Brushes in traditional DC motors wear out, need regular replacement, produce damaging friction, generate excess heat and reduce energy efficiency and power. Brushless motors BITURBO tools combine a high-performance brushless motor with powerful ProCORE18V batteries to maximise power output and maintain a longer battery life per charge

SPARKS | PASSIVE FIRE STOPPING

Passive fire stopping is an essential requirement in the Wiring Regulations (BS 7671:2018) and key to the Health and Safety at Work Act, Electricity at Work Regulations and Construction (Design and Management Regulations).

DON’T LEAVE FIRE STOPPING TO CHANCE!

“ULTIMATELY, WE ALL HAVE RESPONSIBILITY WHEN IT COMES TO FIRE SAFETY.”

Gary Parker, ECA Technical Manager, explains the Dos and Don’ts of Passive Fire Protection and how to avoid falling short in this essential aspect of installation and design.

DO:

WHAT IS PASSIVE FIRE STOPPING?

Unless they are properly sealed, holes for cabling or other services in a building’s compartments can create a gateway for fire. So, wherever a hole is made, fire stopping will also be needed.

KEY QUESTIONS TO CONSIDER:

■ How long should the fire stopping material delay a fire?

■ Does the material need to bear weight, e.g. if it forms part of a floor?

■ Avoid making unnecessary or unplanned holes, gaps, or voids in compartmentation areas ■ Follow the correct methods for fire stopping required by manufacturers ■ Use materials that will sufficiently withstand fire and heat ■ Raise any concerns about the effectiveness of compartmentation with your supervisor or line manager ■ If requirements for fire stopping are not clear, notify the client or building owner immediately.

■ Does any electrical containment require fire stopping on the inside and the outside?

■ Will any services need to pass through the barrier in the future?

20

For more info visit: www.eca.co.uk/technical

| AUTUMN 2021 > WWW.SPARKS-MAGAZINE.CO.UK

DON'T:

■ Create any unnecessary breaches or holes in fire compartmentation ■ Leave any penetrations with no fire stopping ■ Deviate from the required fire stopping specifications for the task in hand ■ Use makeshift filling methods or materials to block holes or gaps in compartmentation.

IF IN DOUBT, LEAVE IT TO THE SPECIALISTS

Fire-stopping, in all but the simplest of cases, is best assigned to specialist service providers. Ideally, a specialist subcontractor should be involved at all stages of construction.

Ultimately, we all have responsibility when it comes to fire safety. It should never be left to chance.

CASE STUDY | SPARKS

Amy Barratt-Singh

ENCOURAGING WOMEN INTO THE SECTOR

Women make up just 3% of electricians working in the UK. That’s why, when Ideal Industries heard about Amy Barratt-Singh, aka AmytheSparky, they were keen to support her with sample products and sponsorship.

AMY'S STORY SO FAR:

■ I studied as a mature student, paid my own way and was the only woman on my course ■ Getting people to take me seriously was quite challenging at first ■ I started my YouTube channel and Instagram to encourage other women to work as electricians and in the trades

“IDEAL INDUSTRIES IS KEEN TO PLAY A PART IN ENCOURAGING A MORE DIVERSE PROFESSION.”

■ My advice is to get as much experience as you can by working in different environments ■ I feel that companies can encourage more women into the industry by putting women on their website and in their marketing materials ■ The most rewarding part of my job is that I’m doing what I love!

AMY SAYS:

ENCOURAGING DIVERSITY

Brett Smyth, general manager EMEA at Ideal Industries says, “With role models like Amy inspiring a new generation of potential electricians, Ideal Industries is keen to play a part in encouraging a more diverse profession.”

I love the Ideal Industries FT-45 Feed Thru modular plug system for data terminations.

CIRCUIT PROTECTION | SPARKS

RCBOs – WHAT AND WHY? An RCBO provides protection against several types of faults and guarantees power continuity on healthy circuits. Mike Cash at Electrium explains what you need to know.

WHAT IS AN RCBO?

An RCBO is a “residual current operated circuit breaker with overcurrent protection” i.e. a combined MCB and 30mA RCD device.

WHY SHOULD YOU USE RCBOs?

Circuits in residential applications require additional protection from a 30mA residual current device. Using RCBOs provides individual protection to each circuit which avoids unwanted tripping and keeps all healthy circuits operational.

“USING RCBOs PROVIDES THE NECESSARY PROTECTIONS WHILE AVOIDING UNWANTED TRIPPING ON HEALTHY CIRCUITS, WHICH REDUCES RISK AND AVOIDS DANGER & HAZARDS.”

WHAT DO THE REGULATIONS SAY?

314.1 requires installations to be divided into separate circuits to avoid danger in the event of a fault, and to be designed to avoid hazards caused by the failure of one circuit e.g. a lighting circuit.

If one 30mA RCD serves several final circuits - sockets, shower, lights, a fault on the sockets, or shower – will disconnect the faulty circuit and the lighting and that will cause the hazards that 314.1 intends to prevent.

Avoiding unwanted tripping of RCDs from excessive PE currents is required by 314.1 and 531.3.2. The PE current must be no more than 9mA for a 30mA device. But multiple circuits and multiple PE currents could cause frequent unwanted tripping when several appliances, consoles, PCs etc are used.

Using RCBOs provides the necessary protections while avoiding unwanted tripping on healthy circuits, which reduces risk and avoids danger and hazards.

That’s a compliant solution.

For full details of regulations relating to additional protection by 30mA device please see BS 7671:2018.

TOP 5 ESSENTIAL TOOLS WITH SIMON BRYANT When it comes to being a spark, without our essential tools we wouldn't be able to work so selecting the right equipment is key.

We asked Simon Bryant to help us put together a list of essential tools for every new spark’s toolbox.

TOOL 03

What kind of spark would you be without the humble hammer? You’ll find you’ll lose a lot of these over the years! Wiha have an ergonomic hammer for your everyday spark and it doesn't break the bank.

“YOU’LL FIND YOU WILL LOSE A LOT OF HAMMERS OVER THE YEARS!”

@Simonbryantelectrical There’ll be an apprentice giveaway soon.

TOOL 01

With electrics you’ll always need testing equipment. Once you're qualified you will need a multifunctional tester, but for now a voltage indicator is essential.

Not only does this prove if voltage is live but you’ll need it to do basic continuity testing. Belling out cables is a great way to identify circuits and helps prepare you for fault finding.

TOOL 02

When it comes to side cutters, I would recommend getting some with notches for stripping inner cores of cables. These Knipex ones have two notches, one for stripping 1mm/1.5mm and one for 2.5mm.

The CK ones have a cutting hole for 3.5mm faceplate screws which can come in handy.

TOOL 04

When it comes to the finishing touches a torque screwdriver is essential to get the terminals at the right torque. This is essential for EICRs and consumer units.

Who doesn't love a fuse board change?

TOOL 05

I use the Milwaukee M12 Compact everyday, which lives in my Veto Tech Pac. The hex tool holder is quick and easy; you will never have a drill bit fall out again.

SPARKS | FEATURE: SURGE PROTECTION

UPSKILLING WITH DEHN ACADEMY With surge protection devices becoming a largely mandatory part of the wiring regulations, in the 18th Edition, we’ve asked Dehn UK how they’re helping the next generation.

T

raditionally, electricians haven’t always been involved in this niche area of the electrical industry, relying heavily on specialist subcontractors but with the increase in the use and installation of these systems and devices it’s becoming far more important for electricians (and especially trainees & apprentices) to increase their knowledge in these areas.

“…IT’S BECOMING FAR MORE IMPORTANT FOR ELECTRICIANS (AND ESPECIALLY TRAINEES & APPRENTICES) TO INCREASE THEIR KNOWLEDGE IN THESE AREAS.”

With global warming there’s been an increase in lightning activity across the UK over the last two decades, therefore more people are likely to feel the effects of lightning and surge events.

TOP TIP

Make sure you are upskilling to keep pace with this important & highly specialised industry segment.

You can find details of all the different course options here:

DEDICATED TRAINING ACADEMY

DEHN UK, a leading manufacturer of lightning protection and surge protection products, are well aware of the knowledge gap. So they have sought to address this directly by opening the UK’s first dedicated training academy for lightning protection, surge protection and earthing applications.

32

COURSES

Courses are available on the requirements of surge protection to BS7671, lightning protection to BSEN 62305, all fully accredited by CIBSE. They are all delivered by subject matter specialists in a mixed use space, offering technical class-based instruction alongside a practical demonstration space.

Examples are shown of devices installed with different installation options and of over current protection.

HOW SPDs WORK Surge Protection Devices (SPDs) are specifically designed to protect electronic equipment from extremely short duration high voltage spikes.

BEAMA explains more in this article.

“AN SPD DIVERTS THE SURGE CURRENT TO EARTH AND LIMITS THE OVERVOLTAGE TO A SAFE LEVEL.”

T

he operation of electronic systems can be severely affected by lightning activity or electrical switching events. Both can cause short duration high voltage spikes or transients on mains power and/or data communication/signal/telephone lines, with potentially devastating consequences to installed equipment. These increases in voltages are called surges or transient overvoltages. An SPD diverts the surge current to earth and limits the overvoltage to a safe level.

THE SOLUTION

Circuit breakers/fuses are designed to protect your home, business, equipment, and possibly even your life from an event such as a short circuit or overload. They are not designed to provide overvoltage protection. This protection is provided by SPDs which are specifically designed to redirect the harmful voltage away from the equipment.

HOW SHOULD SPDS BE INSTALLED?

SPDs are connected to the power supply in parallel with the load circuits that it is intended to protect. Depending on the type selected, SPDs are typically installed at the supply input point, the distribution board or near the equipment to be protected. Reputable manufacturers provide tailored solutions for various applications.

To find out more about the BEAMA Manufacturers Trade Association go to: www.beama.org.uk

WHAT DO THE WIRING REGULATIONS STATE?

In brief, the Wiring Regulations (BS 7671) state that adequate protection for both people and equipment from transient overvoltages of atmospheric origin transmitted via the supply distribution system and against switching overvoltages must be provided.

How do I find more information?

■ Study sections 443 and 534 of the Wiring Regulations ■ Read the BEAMA Guide to SPDs Selection, Application and Theory.

SPARKS | LIFE SKILLS

CONFIDENT? FEEL IT, BE IT When it comes to self-confidence it’s all about striking the right balance. It's being sure in yourself and your ability - not arrogantly, but realistically. It’s about you and your own awareness that you are capable.

HOW TO IMPROVE CONFIDENCE

Improving confidence has two parts increasing the confidence you have in yourself and your abilities and developing your ability to appear more confident to other people.

PLAN AND PREPARE

Planning and preparing is the most important part of feeling confident.

“TOO LITTLE CONFIDENCE CAN STOP YOU TRYING NEW THINGS. TOO MUCH CONFIDENCE—CONFIDENCE NOT GROUNDED IN REALITY— CAN LOOK LIKE ARROGANCE.”

For example, if you have an interview imagine what you want to say and think about some of the questions you might be asked. Practise your replies with lecturers or classmates. How will you get to the interview, what should you wear, how long will it take to get there? Knowing that you are prepared will create a feeling of confidence on the inside which will make you look confident on the outside.

THINK POSITIVELY

Positive thought is a powerful way of improving confidence. Tell yourself that you can do anything with the right help, support, preparation and work.

IDENTIFY A ROLE MODEL

Who has confidence that you admire?

It might be a work colleague, lecturer, a family member or friend. What do they say, how do they move, how do they speak? When something goes wrong, how do they react? Speak with them to understand more about how they think and what motivates them.

LIFE SKILLS | SPARKS

HOW TO APPEAR MORE CONFIDENT

You can project self-confidence in your behaviour, your body language, in what you say and how you say it. When meeting a customer, speaking with your boss, or giving a presentation you may feel shy or selfconscious, but you can do things to make you appear more confident.

■ Maintain eye contact. This shows that you're paying attention to what the other person is saying.

■ Don’t fidget or look away. This will make you appear distracted or anxious.

KIMMY

■ Sit up straight. When we are nervous, we slouch, hunch our shoulders, and lower our heads to make ourselves appear smaller.

Simply sitting up straight can help you feel and look more confident.

THE SPARKS

■ Stand up tall. This will help you breathe more freely but it also makes you look and feel more confident.

■ Speak slowly and clearly. Rushing what you’re saying or speaking quietly can make you sound unsure. Taking your time will make you feel calmer.

Don’t allow negative self-talk and never stop learning – knowledge helps us gain confidence over time.

Remember – the more you practise these techniques the more natural they will feel.

@kimmythesparks

HANDY HINT

Self-confidence is about believing in yourself and in your abilities.

You don’t have to have all the answers or succeed in everything you do! Just trust in yourself and believe that you’ll be okay no matter what.

EASY HIGH BAY INSTALLATIONS

“ENERGY SAVINGS ARE AT THE TOP OF MOST CUSTOMERS’ AGENDAS.”

When mounting high bays at heights of 15m, challenges present themselves. Tungsram’s new Auriso (IP20) and Duros (IP66) help to alleviate some of those problems. Here we find out how.

LIGHTWEIGHT

Whether using a ladder or scissor lift, mounting heavy luminaires above your head is difficult. The new Highbays from Tungsram are extremely lightweight when compared to the light output. Up to 60K lumens can be produced from a single fixture – traditionally you would expect weights of 5kg+. These highbays have all unnecessary weight stripped out whilst maintaining the required amount of heat dissipation to ensure a long life.

PREFABRICATED BRACKETS

Typically, brackets are an add-on accessory that are often forgotten when ordering. Highbays turn up on site and there is no way to mount them. The Duros and Auriso have brackets built into the fixture. If suspension is required, Y-cables or pendant mounting options are also available.

BUILT-IN SENSORS

Energy savings are at the top of most customers’ agendas, so the expectation is that lighting is on only when needed.

Auriso and Duros have on-board sensors that control lighting based on motion (SN), daylight harvesting and motion sensing (RFM) or simply on/off (RFS).

These features avoid electricians having to install secondary sensors, saving time and money.

MUCH DO YOU NEED? 1 HOW

Consider how much natural light there is in the space you are designing and where the doors and windows are positioned. This will help you choose the right amount of light and locate individual fittings most effectively.

“LIGHTING IMPACTS PRODUCTIVITY, ALERTNESS AND MENTAL WELLBEING, SO CONSIDER WHAT SPACE THE LIGHTING IS FOR.”

LIGHTING RULES 2 THE

75% of lighting in new builds must be energy efficient. So, a new lighting design may have to produce 400 lumens with a minimum efficacy of 45 lumens per watt and be over five circuit watts

APPROACH 3 HUMAN-CENTRIC

FIVE STEPS TO LIGHTING DESIGN Lighting design can be daunting, so a well-structured design process is the way to go.

Ansell Lighting highlights five considerations to help achieve the perfect end result.

HANDY HINT

Allow approx. 25 watts – or 250 lumens – per metre of space.

Lighting impacts productivity, alertness and mental wellbeing, so consider what space the lighting is for. Smart-lighting is human-centric, due to the overall control and ability to adapt and change light, and replicate natural light, so can suit most applications.

OF LIGHT 4 COLOUR

Ideally, artificial lights should replicate natural light. Daylight fluorescent tubes make it possible to illuminate large spaces economically. Where a natural effect is less important, such as industrial or street settings, use highly efficient discharge lamps.

CONTROLS 5 SMART

Smart lighting control systems save money and energy by allowing control and scheduling of individual lights and intensity. Using smart swathes, daylight controls and motion sensors help to control the light, allowing different lighting levels to be allocated for various tasks and spaces.
