13A EV socket

lyledunn
TNCS system in local development. Second hand BMW 330E Hybrid with ICCB that appears to restrict charging to 6A. Owner wants 13A socket on outside wall of house. 

The area is near the Mourne mountains where an Ra of 200 ohms would be difficult to achieve with a single rod. In any event the driveway has just be nicely finished. It would be a simple matter of drilling through the back of the meter cupboard to provide  the 13A socket but it is the loss of neutral protection that is the problem. Anyone know if loss of neutral protection is available as a separate item?

    Quite. Had they asked for a 13A socket for a Christmas tree or a lawnmower, we would not blink at exporting the PME earth, being  happy that really the socket for that sort of thing may as well be 2 pin, as the earth is not really exported with most outdoor electrical appliances, due to double insulation.

    In the street will be metal  PME lamp posts and lights in metal frame PME bus stops, and the main source of trouble will be grafitti or rubbish, not earthing.

    I can imagine that depending what was asked - 'can I have a socket by the front door here?' there would be no issue raised. Later someone plugs a car in, still almost always no problem. But having opened the can of worms that is car charging, in effect the lost neutral detectors that have no earth are really not much more than a low voltage and high voltage cut-out, except that they break the CPC as well as L and N when operating,
