Amendment 1 to BS 7671:2018 has been released

Amendment 1 to BS 7671:2018 has been published today as a standalone, free-to-view version on Section 722 (electric vehicle charging installations only).

The update enables a more practical solution for electric vehicle charging installations and follows advances in technology that were unavailable when BS 7671:2018 was first published. It will also assist the industry to support the Government’s target of at least 50% of new car sales to be ultra-low emission by 2030, enabling the installation of charging points to be easier, quicker and reduces the cost of installations to both installers and consumers.

Changes made to Section 722 include:

Protection against electric shock
Regulation 722.411.4.1 concerning the use of protective multiple earthing (PME) supply has been redrafted.

The new and amended requirements around PME are intended to keep pace with technology, while increasing the ability for an installer to use PME on EV charging equipment installations. This means that more charging points can be installed, helping the roll-out of EV infrastructure across the country.

In addition to changes to the existing information, two new indents have been added:

(iv) to cover a single-phase installation, and

(v) to allow the use of an alternative device to those in (iii) or (iv) which does not result in a lesser degree of safety than using (iii) or (iv)

Regulation 722.411.4.1 does not allow PME to be used to supply an EV charging point unless one of the methods described in (i), (ii), (iii), (iv) or (v) of 722.411.4.1 are used.

Further Information
BS 7671:2018+A1:2020 will be published on 3rd February 2020. To view a free version (non-printable) visit electrical.theiet.org/bs-7671/updates/
