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?

    Let's not confuse street installations vs consumer installations.


    The guidance in A722 directs you to consider the demand of the installation if you are using an earth electrode to attempt to limit the touch voltage [at the same time, I'll openly say I think this is rarely practicable, especially for single-phase installations). I do accept it may be more than one installation you have to consider in the big picture, but that's not what BS 7671 is telling us. This may well be down to doing what you reasonably can do in practice (although it's not very practicable).
