SELECT provides industry guidance on the newly launched 18th Edition of the IET Wiring Regulations

IET Wiring Regulations

SELECT, the campaigning body for the electro-technical trade in Scotland, has been updating its members on key points from the newly launched 18th Edition of the IET Wiring Regulations. SELECT’s Technical Standards Adviser, Bob Cairney, prepared the guide which is available in an on-line format to assist members to understand the changes contained in these important regulations. The guide will also feature in the next issue of SELECT’s CableTalk magazine. Bob said:  “BS: 7671:2018 (The 18th Edition of the IET Wiring Regulations) contains a number of significant changes which reflect industry best practice. We have recently been out on the road to highlight the changes during our recent very successful Scotland-wide Toolbox Talks. These were held a few weeks ago and the presentations were well received by the members who attended”. A central theme of the regulations concerns improvements to the level of safety provided in new electrical installations and in particular with regard to fire safety. The 18th Edition introduces new devices called arc fault detection devices (AFDD) and these, where installed can provide an additional level of electrical safety from faults which other protective devices cannot detect specifically arcing faults. These are expected to be widely adopted by the industry. There is also new guidance on types of RCD and arrangement of devices to achieve selectivity between protective devices. Also of interest is informative guidance on energy efficiency. Darrell Mathews, Managing Director of SELECT, said: “These regulations incorporate the latest in technological developments across our sector and, while they do not come into force until 1 January 2019, we want SELECT members, as ever, to be in pole position.” NOTES TO EDITORS SELECT, Scotland’s largest trade association, has over 1250 member companies who collective turnover is around £1 billion and provide employment for 15,000 people. Its members are responsible for over 90 per cent of electrical work carried out in Scotland. Bob Cairney, SELECT’s Technical Standards Adviser, has 40 years’ experience in the electrical industry.
