BS 1363 socket for EV charger - what kind of RCD?

[Selfmade]

WTF?

I'm sure this one has been debated endlessly on here, but as far as I'm concerned, if it's metal and partly buried in the ground it's 'liable to introduce an earth potential' so needs main bonding.

The door frame is metal so will probably be extraneous and need bonding back to the intake.

I HAVE JUST KICKED THE CAT FOR READING THAT .

Already read it, but thanks anyway. I've actually done quite a few garages and sheds, just never a car charger (up until now). I'm sure someone reading this will find the link helpful though!

Probably Scolmore Click 1-gang switched. Unless the customer decides on metalclad.

Think I may be getting somewhere with this: Type B DC Sensitive RCD | WYLEX - https://news.voltilink.co.uk/e-catalogue/brand/wylex/family/type-b-dc-sensitive-rcd . All I need to do now is find somewhere that sells them. Kinda dreading the price!

Trade price £546.33! Gonna keep looking...

Check the socket specs

The manufacturer of the car will specify what type of RCD is required.
Usually its a A type for anything up to 32amp. With larger and 3 phase charging point usually require a B type RCD.

If you using a 13amp socket I'd protect it by a A type RCD the charging lead will have a inline RCD too.

Check the socket specs

It is a standard 1363 socket.

 

[netblindpaul]

Is it suitable for ev charging then?

 

[AJshep]

You can charge a Tesla from a 13amp socket my friend has one but I believe it took him around 24 hours to fully charge the car

I installed a IP65 32amp interlocked socket for him with a Separate earth electrode.
The data sheet from Tesla specified a A type RCD.
