13amp outdoor ev charging socket

[sparky308]

2.5 cable from the OP's consumer unit. Where does 40m come from? Anyway the volt drop for 40m of 2.5 drawing 10 amps is 7.2 volts or 3.1%. So I can't see a problem here.

2.5 T&E on a 16A RCBO will be fine. I charge my EV overnight on an outdoor 13A socket, charge rate set at 10A, it doesn't even get warm.

Iv heard loads of horror stories about normal 3 pin sockets warping cracking etc that's why I'd be more comfortable using the thicker cable. The run from CU to socket position is only about 3 metres.

The cable size won’t stop cheap sockets from over heating BUT a proper EV point would

Yes I would only ever get a EV marked socket nothing else

That depends on how small the cable is

Using 4mm cable won't make the socket or plug a different temperature than using a 2.5mm cable! Heat is caused by resistance in the plug/socket contacts. Use a quality EV rated socket plus a quality charger cable and there will be no problem.
