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?

    We are waiting for instruction from the company. Meanwhile the lady cracks open the garage door to feed a trailing lead through with the end tied in a plastic bag. Despite me telling her that the risk of loss of neutral is extremely low, I think that she is scared stiff to go near her car while on charge! All things being equal, it would have been better to have installed a simple IP rated socket until her company agreed to pick up the tab for a compliant arrangement. At least that way it would have reduced the risk with the plastic bag and kept the opportunistic burglar from raiding her garage! 


    Hi Lyle, thanks for the reply.


    I would have thought the instructions would be available on-line?


    Perhaps reassure the lady that she is as likely to die or be seriously injured by changing the bulb in an outdoor metal class 1, using a 110V cement mixer or using an outside tap from the same perceived risk that is posed by a car on charge? Maybe a surge protected socket to protect a £10-30K appliance wouldn’t go amiss?

    She doesn't have to. Isolate the EVCP, plug in, and energise. On completion, isolate and unplug. Of course, should a thief get zapped whilst attempting to steal the vehicle when the neutral has been lost, that would be his own bad luck. ?
