Wiring Regs: Amendment 1 published
Amendment 1 of the 18th Edition of the Wiring Regulations (BS 7671:2018) has been released, and is now in full effect.
The Amendment allows advances in EV charging technologies which weren’t available at the time of the original publication of the 18th Edition.
The main change has been the addition of regulation 722.411.4.1 (iv). This gives an option specifically for protection against electric shock in a single-phase installation, by using a device which electrically disconnects the vehicle from the live conductors of the supply and from the protective earth within 5 seconds.
“ECA welcome the release of Amendment 1 as it takes on board advances in technologies not previously available. In addition, it will offer electrical contractors a method of providing safe and compliant electrical vehicle charge point installations for buildings with a single-phase electricity supply. This solution will avoid the need to undertake potentially dangerous groundworks or use expensive and heavy isolation transformers”, commented ECA’s Luke Osborne.
The full Amendment can be viewed for free, or downloaded for £5, at the IET website.
