Wiring Matters (Issue 86) July 2021

This is a look at what’s inside Issue 86 (July 2021) of the IET Wiring Matters magazine.

The framework for energy efficiency in electrical installations

This is Part 2 of Cameron Steel’s 3 part series of articles on energy efficiency in electrical installations.

Setting up a basic electrical maintenance regime

Electrical installations and the components within them are sometimes taken for granted and once installed, have an expectation to provide reliable, continuous service indefinitely.

Hot tubs

The IET has recently received an influx of calls on the helpline regarding the confusion surrounding hot tub installations. In this article, we try and provide clarity by examining the facts available to assist the designer in making an informed decision to avoid finding themselves in hot water.

Back to the Forum – Thermal effects

Discussions on renewable energy have made it to the IET Engineering Communities forum several times recently. Renewable electricity will play a crucial part in achieving ambitious UK Government emission targets, but this will mean an increased maximum demand for electrical installation. In this article, we look at the effects of increased temperature and thermal effects on cables and consumer units.

Electric vehicle chargepoints set to become next great British emblem

Electric vehicle chargepoints across the UK could become as recognisable as the red post box or black cab, following the appointment of the Royal College of Art (RCA) and PA Consulting to deliver an iconic British chargepoint design, Transport Secretary Grant Shapps has announced today (9 August 2021).

The design will be unveiled at COP26 in Glasgow this November and could be seen on streets across the country from 2022. The chargepoints will be functional and accessible for all users with sustainability at the heart of the design.

This project gets underway as independently produced statistics from Zap Map reveal there are now over 25,000 public charging devices across the UK – a major milestone, which means that electric vehicle drivers are never more than 25 miles from a chargepoint on UK roads. This comes as recent statistics from the Society of Motor Manufacturers and Traders (SMMT) show that over one in 6 cars sold in July 2021 had a plug.

In the run-up to COP26, the UK government is calling on countries around the world to accelerate the transition to electric vehicles, which – along with phasing out of coal power and halting deforestation – are crucial to keeping warming to 1.5°C. As part of that, having the right charging infrastructure in place is crucial.

Transport Secretary Grant Shapps said:

Excellent design plays a key role in supporting our transition to zero emission vehicles, which is why I want to see EV chargepoints that are as iconic and recognisable as the British phone box, London bus or black cab.

With less than 3 months to go until COP26, we continue to put the UK at the forefront of the design, manufacture and use of zero emission vehicles and their charging infrastructure, as we build back greener and call on countries around the world to similarly accelerate the transition to electric vehicles.

The rollout will allow chargepoints to be more recognisable for drivers, helping to create awareness around the transition to EVs – and linking them to the iconic British designs of old that are recognised the world over.

Today’s announcement follows the launch of government’s Transport decarbonisation plan, a world-leading ‘greenprint’ published earlier this summer that sets out a credible path for the UK to achieve net zero emissions by 2050 and lead the world in tackling climate change. It also comes alongside an array of government interventions to ensure charging is as easy as, if not easier than, refuelling a petrol or diesel car or van.

Clive Grinyer, Head of Service Design at the RCA, said:

This is an opportunity to support the design of a future icon that will be part of our national culture as we move towards a sustainable future. The RCA has been at the forefront of shaping our products, mobility and services for the last 180 years. We are delighted to be playing a role in the design of the total service experience to ensure a usable, beautiful and inclusive design that is an excellent experience for all.

Warwick Goodall, transport and net-zero mobility expert at PA, said:

We know that excellent design has the power to dismantle barriers to growth and simplify the user experience, making the switch to electric vehicles more attractive, accessible, affordable and secure for drivers.

PA has a strong legacy in product design, which is an integral part of our world-leading end-to-end innovation capability. The combination of PA’s world-class design team and the Royal College of Art brings the creative expertise to reimagine the EV chargepoint as an iconic piece of British street furniture.

We look forward to working together with the public and industry on a design framework that will accelerate the chargepoint rollout ambitions and bring to life the electric vehicle revolution on our streets.

Product Recall – TIME Cable 2 Core Flexible Cables

TIME Cables would like to make customers aware of a safety concern with regards to the below TIME Cables products sold via B&Q and Tradepoint from December 2020 to April 2021.

A printing error on the packaging has resulted in the incorrect amp rating of 25A being advised, as opposed to 6A, 10A or 16A.

The printing error may result in the product(s) being used for an installation which draws in excess of the current for which it is officially rated, potentially causing a risk of fire. Please check with your installer that these products have not been used with such applications.

The affected products were on sale between December 2020 & April 2021.

Product Recall – 6 Lamp Chandelier

The product presents a risk of electric shock as the basic insulation of the wiring was in contact with accessible metal parts. The ceiling cowl also had no provision of earthing and class II construction had not been met.

The instructions supplied with this sample were also considered to be inadequate as they do not contain adequate safety information and details to ensure the correct and safe use and installation of the product.

The product does meet the requirements of the Electrical Equipment (Safety) Regulations 2016.

The rewire of Buckingham Palace

We were recently looking online and found some information regarding the rewire of Buckingham Palace, this started a few years ago in 2018 but the information is still relevant as they reckon it will take 10 years to do all the required work on this building !

The work is to rewire the building, but remember this is not your typical 3 bedroom house.

From what we understand there is 775 rooms. It has 6500 plug sockets and 5000 light fittings. An estimated 100 miles of electrical cabling.

The electrical cabling and heating have not been updated since shortly after the Second World War in the 1940s.

Work is currently underway to remove a further 1.5km of VIR cabling from State Rooms including the Picture Gallery, Blue Drawing Room, Music Room, White Drawing Room, and Throne Room.

It’s also surprising to find out there is no maps or plans that show where any of the original cables go.

The below image is from a blog post on the Royal UK website and shows the work been undertaken.

The below video has some interesting facts and video footage from the rewire at Buckingham Palace.
