EV charging point - no for protection

At a customers house today, he asked me to add an outside socket. There's a spare way in an IP65 consumer unit outside next to the intake. On inspection, it's supplied off  a Henley block, it's not a sub board, but there's no RCD protection, just a surge protection device. There's a standard bs7671 label about testing the rcd, that's all..

I''m not registered to fit EV points so the customer can't claim any grants like he could of this person: but surely unless I'm missing something,they can't be a spark if they think the SPD is going to provide supplementary electric shock protection. They are a proper registered EV installation  firm, are they right and I'm wrong? Do I report it? To who? What if he fits them all like this?

  • You may want to refer to regulation 722.531.3.101 on RCDs, which states each charging point incorporating a socket-outlet shall be protected individually by an RCD. I believe this is referring to the charger having a built in RCD.  However, depending on the installation method, additional 30 mA protection for the circuit may be necessary. Regarding the SPD, it is possible that the installer and the client had a discussion and agreed to install it for protection against transient overvoltages, which could cause significant financial loss if they damaged the EV charger.
