The Institution of Engineering and Technology (IET) has published the 18th Edition of the IET Wiring Regulations. Projected as an essential publication for all professionals working in the electrical industry, IET Wiring Regulations forms the national standard to which all new and amended electrical installations in the UK are to comply. The IET urges all electrical professionals to ensure they are familiar with the changes before the new requirements come into effect from January 2019.
Significant changes include: recommendations for Arc Fault Detection Devices (AFDDs) in AC final circuits, requirements for devices for protection against overvoltage, a change to the requirement for the methods of supporting wiring systems within buildings against their premature collapse in the event of a fire and a new Appendix focusing on energy efficiency.
Changes have also been made to the requirements for electric vehicle charging installations with PME supplies (the most common form of earthing in new installations) as well as new guidance for the design and erection of electrical installations that have local production and storage of energy for optimising efficiency.
The changes to BS 7671 come from the revision of international and European standards, of which the UK is obliged to take on the technical intent. JPEL/64 members represent the UK on many of these international committees and the content to be included is discussed in terms of the impact on UK industry, before a new update to BS 7671 is agreed and published.
BS 7671:2018 and the IET's popular suite of guidance are available from www.theiet.org/wiringbooks.
To accompany the 18th Edition, the IET is launching online training for the City & Guilds 2382:18 qualification. The only online training to be endorsed by City & Guilds for this qualification, the Full and Update courses both offer flexible learning, in their own time at own pace. Accessible via an app, the training also includes three, full, practice exams to fully prepare for the real thing.
