When did type A RCD's become a requirement for EV chargers

Alan B

I am just looking at a potential EV charger installation for a house that has supposedly been prewired for an E charger but it's protected by a type AC RCCB. Then to make things worse it's in an easy 9 consumer unit and the only type A RCCB they have is only rated at 63A, the ev charger is sharing the RCCB with two other 32A circuits plus 4 others. I don't have any space for extra devices and will need to put an extra consumer unit in.

I am wondering if the install ever complied with the regulations. Looking at regulation 722.531.2.101 it's in the first 18th edition but i don't know if ev charging was even in any of the 17th editions?

Also quite shocking that I can't get a 100A type A RCCB from Schneider for the easy 9.

    Amendment 2:2013 to BS 7671:2008, first introduced Section 722. As it was introducing a new Section, it came into force immediately for designs after 31 July 2013 (according to the introduction).

    The Regulation from Amendment 2:2013 reads as follows (and in wording is very different to Regulation 722.531.3.101 that is in the current BS 7671:2018+A2:2022):

    722.531.2.101 Every charging point shall be individually protected by an RCD having the characteristics specified in Regulation 415.1.1.The RCD shall disconnect all live conductors, including the neutral.
    The RCD protecting the charging point shall be at least a type A RCCB complying with BS EN61008-1 or RCBO complying with BS EN 61009-1. If it is known that the d.c. component of the residual current exceeds 6 mA then a type B RCD complying with BS EN 62423 shall be installed.
