A standalone free-to-view amendment on Section 722 of BS 7671 on IET Wiring Regulations only.
The amendment follows advances in technology that were not available when BS 7671 was published, enabling a more practical solution for the installation of charging points.
This means that it will be easier for the industry to help support the government’s target of at least 50% of new car sales to be ultra-low emission by 2030.
The updated Section 722 in BS 7671 will make installing charging points quicker and easier and will reduce the cost of installations for both installers and consumers.
Amendment 1 to BS 7671 on IET Wiring Regulations is an update to Section 722 (electric vehicle charging installations) only.
The changes made to this section include:
Protection against electric shock
Regulation 722.411.4.1 concerning the use of protective multiple earthing (PME) supply has been redrafted. 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 is used.
The new and amended requirements in BS 7671 on IET Wiring Regulations 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 rollout of EV infrastructure across the country.

The Code of Practice for Electric Vehicle Charging Equipment Installation is also being updated in line with Amendment 1.
