you are very vague on information .

Who me? I thought I'd given all the info relevant to my question? And I don't see how you've arrived at 'try B' from knowing the system and location? From my reading of the regs the only thing that seems to affect the choice of A versus B type RCD is the level of DC residual current. Have I missed something? I do really appreciate your help, I'm just not sure I understand what you are saying and why?

how long have be sparking self made ?

6 years - not very long, but longer than there have been regs specific to EV charging points lol - I remember them coming in (Ammendment 2).

Problem is here you are installing a standard 13A socket outlet which could be used for any purpose.

Garage is attached to house but with no access from one to the other.

OK, will see if I can describe the situation in a bit more detail. I've been asked to quote for a garage installation (currently no power in garage) among other things. The supply is TN-S. One of things that will be used in the garage is a charger for a hybrid car. The charger has a 13A BS1363 socket, so will draw 13A or less (probably close to 13A). I've no plans to add an earth electrode as system is TN-S and as far as I am aware the car will be charged in doors. I'll be installing a CU in the garage (probably 5 way), 10mm2 (probably SWA) fed from 40A MCB in house CU. The will be a 32A sockets circuit and 6A lighting circuit in garage and a separate 16A/20A circuit for the car charging point as required by 722.311. The door frame is metal so will probably be extraneous and need bonding back to the intake. Think that covers it.

Maybe so you can plug the kettle in for a brew whilst waiting for the car to charge....

Yes, and the charger could be plugged into another socket. I follow the EV scene a bit on YouTube and the like and EV drivers plug their cars in everywhere - for example when visiting friends they'll run an extension from their friend's lounge to charge their car. Why wouldn't they? The charger has a standard plug on it! Which puzzles me as to why all these requirements are not on the charger manufacturers! But the scope of Section 722 says any socket intended to be used for charging electric vehicles. All that said I don't say any problem with using the charger point for other purposes?

now I get the picture. now that was not so bad was it.

Lol! I'll be marking in 'suitable for electric vehicle charging', so hopefully the car will be plugged into this one and the kettle into one on the main sockets circuit!

WTF?

No, but if I'd put all that in the first post and it had been twice as long, maybe no-one would have read it
