The Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020
Between 17 February and 16 April 2018, the government invited comments on the Electrical Safety Standards Working Group’s decision to make a recommendation to introduce mandatory inspection and testing for private rented properties.
Getting important labelling right leaves a lasting impression
What you leave behind after an installation speaks volumes. While electrical labelling is most importantly about safety, it should also be convenient, professional, time-saving, making your life easier and leave a lasting impression with your customers.
Lets take a look at what was in Wiring Matters – Issue 77 September 2019
Brief introduction to the deployment of medical IT systems
Patients undergoing acute care in healthcare establishments (such as hospitals) require enhanced reliability and safety of the electrical installation as well as the safe and reliable operation of the medical electrical (ME) equipment used. This is to provide security of supplies and minimize the risk of electric shock.
BS 7671:2018 Frequently Asked Questions
The IET’s technical helpline receives a wide range of frequently asked questions. Here are just a few of the common questions received.
Setting the Standard
This article explores a brief history of standardization, the current process of standardization and why it is so important for our industry today.
IET announces new amendment to BS 7671 (IET Wiring Regulations)
The IET has announced a new amendment to BS 7671:2018 (IET Wiring Regulations 18th Edition). The national Wiring Regulations committee, JPEL/64, today agreed the publication of Amendment 1, which will consist of a stand-alone update to Section 722: Electric Vehicle Charging Installations.
Solar & Storage Live
The IET are pleased to announce that they are partnering with Solar & Storage Live again this year (17th – 19th September, NEC Birmingham).
Which RCD Type?
Residual Current Devices (RCDs) are safety switching devices. They are designed to provide safety for three types of protection, this section takes a look at them.
Setting the Standard continued, A-Deviations
In the previous article (Setting the Standard- Issue 77) they briefly described the process of standardisation from international to national level. One area that they did not discuss in detail relates to a situation a national committee is faced with when an EN or HD cannot be implemented at national level.
Issue 76 of the IET Wiring Matters magazine is out now ! Here is a brief look at what is in this issue :-
Protective bonding habits
Over the years, the requirements for protective bonding in the IET Wiring Regulations have changed. This article expands on James Eade’s November 2018 Wiring Matters article, where he touched upon some items of metallic equipment, which are usually bonded even when they are not considered to be extraneous-conductive-parts.
Latest developments in International Standards for supplies for electric vehicles
In this article they look at some of the international standards for electric vehicle charging.
An Interview with Michael Peace
The IET’s newest Senior Engineer, Michael Peace, will be familiar to Wiring Matters readers as the author of last issue’s article ‘To Bond or not to Bond’. The IET’s Cameron Fraser sat down with him, and found out more about the newest addition to the team.
As an electrician it is now more important than ever to stay up to date with the latest information and regulations within the industry. Following the Harrogate Elex tradeshow, show sponsors the Institution of Engineering and Technology (IET) are heading to Coventry on the 19th & 20th September.
Crabtree: 100 years of safety remembered and celebrated
Crabtree began on 17th April 1919 when John Ashworth Crabtree designed a quick make and break switch.
In the March 2019 issue they welcome back James Eade’s Mythbusting column, he will brief you on the developments of IEC 60364-8-2 and investigate the importance of working safely with storage.
Here is a quick look at what you can expect to find in this issue :-
Mythbusters #3 – All electrical appliances in the workplace should be tested annually
As myths go, this is a well-established one. A cursory glance at any item of electrical equipment in the workplace is very likely to reveal a green sticker indicating that the testing interval is annual, but should it be? As the IET Code of Practice for In-service Inspection and Testing of Electrical Equipment undergoes revision in preparation for a 5th Edition, James Eade delves into the archives to look at the rationale for testing and where such established practice comes from.
Working safely with storage: It’s not business as usual
Two near misses within the past 18 months have been a timely reminder of unique safety procedures for electrical energy storage systems – Dr Andrew Crossland CEng and EUR ING Graham Kenyon CEng
Lecturing on the 18th Edition of the IET Wiring Regulations in Cyprus
The publication of the 18th Edition of the IET Wiring Regulations has created a surge in demand for local network events to provide updates and insight into the new and amended requirements. The IET Cyprus network requested a visit from a member of the IET Technical Regulations team to give lectures on the main technical changes and new requirements of the 18th Edition of the Wiring Regulations in Nicosia and Limassol and I was happy to volunteer to do them – By: Leon Markwell
Latest developments in International Standards for prosumers low-voltage electrical installations
In October 2018, a new standard, IEC 60364-8-2, was published. In this article, we give a brief overview of some of the latest requirements at international level, which may or may not be incorporated in BS 7671 in the future – By: Geoff Cronshaw
Crabtree: 1919 to 2019 and beyond
Electrical safety has always been at the heart of everything Crabtree does. It’s a philosophy that has seen the brand through periods of depression, a world war, and market uncertainty. It enables them to consistently deliver products and devices that installers can trust, and it all started with a ‘dolly’. (Sponsored)
Energy and Clean Growth Minister Claire Perry announced today the launch of the new joint government-industry Offshore Wind Sector Deal.
Industry to invest £250 million including new Offshore Wind Growth Partnership to develop the UK supply chain as global exports are set to increase fivefold to £2.6 billion by 2030
a third of British electricity set to be produced by offshore wind power by 2030
part of the government’s ambition to make the UK a global leader in renewables with more investment potential than any other country in the world as part of the modern Industrial Strategy
Clean, green offshore wind is set to power more than 30% of British electricity by 2030, Energy and Clean Growth Minister Claire Perry announced today (7 March 2018) with the launch of the new joint government-industry Offshore Wind Sector Deal.
This deal will mean for the first time in UK history there will be more electricity from renewables than fossil fuels, with 70% of British electricity predicted to be from low carbon sources by 2030 and over £40 billion of infrastructure investment in the UK.
This is the tenth Sector Deal from the modern Industrial Strategy signed by Business Secretary Greg Clark. It is backed by UK renewables companies and marks a revolution in the offshore wind industry, which 20 years ago was only in its infancy. It could see the number of jobs triple to 27,000 by 2030.
increase the sector target for the amount of UK content in homegrown offshore wind projects to 60%, making sure that the £557 million pledged by the government in July 2018 for further clean power auctions over the next ten years will directly benefit local communities from Wick to the Isle of Wight
spearhead a new £250 million Offshore Wind Growth Partnership to make sure UK companies in areas like the North East, East Anglia, Humber and the Solent and continue to be competitive and are leaders internationally in the next generation of offshore wind innovations in areas such as robotics, advanced manufacturing, new materials, floating wind and larger turbines
boost global exports to areas like Europe, Japan, South Korea, Taiwan and the United States fivefold to £2.6 billion per year by 2030 through partnership between the Department of Trade and industry to support smaller supply chain companies to export for the first time
reduce the cost of projects in the 2020s and overall system costs, so projects commissioning in 2030 will cost consumers less as we move towards a subsidy free world
see Crown Estate & Crown Estate Scotland release new seabed land from 2019 for new offshore wind developments
UK government alongside the deal will provide over £4 million pounds for British business to share expertise globally and open new markets for UK industry through a technical assistance programme to help countries like Indonesia, Vietnam, Pakistan and the Philippines skip dirty coal power and develop their own offshore wind projects
Claire Perry, Energy & Clean Growth Minister said:
This new Sector Deal will drive a surge in the clean, green offshore wind revolution that is powering homes and businesses across the UK, bringing investment into coastal communities and ensuring we maintain our position as global leaders in this growing sector.
By 2030 a third of our electricity will come from offshore wind, generating thousands of high-quality jobs across the UK, a strong UK supply chain and a fivefold increase in exports. This is our modern Industrial Strategy in action.
The Co-Chair of the Offshore Wind Industry Council and Ørsted UK Country Manager for Offshore, Benj Sykes, said:
Now that we’ve sealed this transformative deal with our partners in government, as a key part of the UK’s Industrial Strategy, offshore wind is set to take its place at the heart of our low-carbon, affordable and reliable electricity system of the future.
This relentlessly innovative sector is revitalising parts of the country which have never seen opportunities like this for years, especially coastal communities from Wick in the northern Scotland to the Isle of Wight, and from Barrow-in-Furness to the Humber. Companies are burgeoning in clusters, creating new centres of excellence in this clean growth boom. The Sector Deal will ensure that even more of these companies win work not only on here, but around the world in a global offshore wind market set to be worth £30 billion a year by 2030.
Keith Anderson, ScottishPower Chief Executive, said:
ScottishPower is proof that offshore wind works, we’ve worked tirelessly to bring down costs and, having transitioned to 100% renewable energy, will be building more windfarms to help the UK shift to a clearer electric economy. Two of our offshore windfarms in the East Anglia will replace all of the old thermal generation we’ve sold and we are ready to invest more by actively pursuing future offshore projects both north and south of the border.
We have a fantastic supply chain already in place in the UK, from businesses in and around East Anglia to across England, across Scotland as well as Northern Ireland. The Sector Deal will attract even more businesses in the UK to join the offshore wind supply chain and we are excited to see the transformative impact this will have on our projects.
In addition, the deal will:
challenge the sector to more than double the number of women entering the industry to at least 33% by 2030, with the ambition of reaching 40% – up from 16% today
create an Offshore Energy Passport, recognised outside of the UK, will be developed for offshore wind workers to transfer their skills and expertise to other offshore renewable and oil and gas industries – allowing employees to work seamlessly across different offshore sectors
see further work with further education institutions to develop a sector-wide curriculum to deliver a skilled and diverse workforce across the country and facilitate skills transfer within the industry
prompt new targets for increasing the number of apprentices in the sector later this year
The cost of new offshore wind contracts has already outstripped projections and fallen by over 50% over the last two years, and today’s further investment will boost this trajectory, with offshore wind projects expected to be cheaper to build than fossil fuel plants by 2020. The Deal will see UK continuing as the largest European market for offshore wind, with 30GW of clean wind power being built by 2030 – the UK making up a fifth of global wind capacity.
The UK is already home to the world’s largest offshore wind farm, Walney Extension off the Cumbrian Coast, and construction is well underway on projects nearly double the size. Around 7,200 jobs have been created in this growing industry over the last 20 years, with a welcome surge in opportunities in everything from sea bedrock testing to expert blade production.
The Deal will look to seize on the opportunities presented by the UK’s 7,000 miles of coastline, as the industry continues to be a coastal catalyst for many of the UK’s former fishing villages and ports. Increased exports and strengthened supply chain networks will secure economic security for towns and cities across the UK.
The government has already invested in growing the offshore wind sector by:
confirming that clean electricity auctions will be held in 2019 and every two years from then into the 2020s, signalling support worth up to £557 million for industry
supporting Local Enterprise Partnerships such as the Humber Local Enterprise Partnership to invest in skills and business support to maximise opportunities in the offshore wind sector
supporting local communities to create new regional clusters and build on their science and innovation strengths with the £115 million Strength in Places Fund to develop stronger local networks
