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?

    Back to the OP. there are Chinese made relay drivers such as the ZHRV2- series that detect loss of neutral (or more accurately out of spec supply voltage ) you can pair up with your own 3 pole (LNE) contactor if you feel brave.   ( example data sheet of the sort of thing.)

    I have not seen this done for equipment in the UK, but in kit that 'goes abroad' and may be used with what is politely referred to as "power of opportunity", which may be a stack of dodgy cables and adaptors or as crude as someone shinning up a pole holding what look like well insulated jump leads, such arrangements are used to auto-disconnect for the most serious errors of connection or infrastructure damage. Needless to say BS7671 does not really apply to those situations, but unlike the UK, often the  ground is very dry so a shock to terra firma is unlikely to be lethal.
