EV Charging using 13amp external socket outlet

Former Community Member
Former Community Member
For an external socket outlet to be used as a dedicated EV charging point, what are the earthing arrangements ? Given it will be RCD protected. I assuming this socket outlet will be considered as an EV Charging point under the regs.


Is mode 1 not allowed in the UK anymore? I read this in an article done by IET Wiring matter "According to a note in IEC 61851 Mode 1 charging is not permitted in the UK". If so why is it still in the regs?


Thanks.

    As you have a copy and I don't, can you tell me if  the RMS test current  or the maximum permitted temperature rise changed ? Resistively heating pins  do not care about the phase  or magnitude of the voltage, just the RMS current.

    I agree interrupting a inductive load involves more burn from the back EMF.

    Given the way an EVSE works there should not be much make (or break) under load unless there is a fault, and there will be a transorb to catch the worst indignity -  if anything I'd expect PF to be a bit capacitive from EMC filters. The one thing there is not going to be is a 50Hz iron core transformer ? Odd.
