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.

    If I was running a 10A plus load for Hours, a 16A BS4343 (Commando) socket would be my socket of choice.

     


    Noting of course that BS 7671 prohibits those in domestic premises, because they are not shuttered.

     



    553.1.201 Every socket-outlet for household and similar use shall be of the shuttered type and, for an AC installation, shall preferably be of a type complying with BS 1363.



    One with an interlocked isolator might be an option, as it's arguably no less safe, but would be a departure.

    OK on caravan and camping sites with kids around (van end of the lead isn't interlocked even if the pitch outlet is) ... but not at home.


    Before anyone asks about the vehicle connectors on EV chargers themselves - BS 7671 permits those, but note that BS EN 61581-1 has requirements such that if the charging outlet is not shuttered, the outlet is isolated when the connector on the lead to the vehicle is removed.
