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?

    If it is a PME supply with TNCS installation then you should use a double pole socket. Don't know if you can get an outdoor weather proof one but there are plenty of indoor makes around , looking at ones yesterday in Homebase. Scowling a bit about all these new silver switch bar ones , excellent looking of course for switches four bars in a row  for a multi gang switch. No the centre pivited long bar on sockets only takes the slighted touch to flick it over' a dog / cat small baby could switch on. Around here with PME/TNCS the main earth goes from the cut-out neutral to the metal consumer earth bar which is bolted to the metal casing , the earths now separate from the neutral in the installation, but do they? no still connected to neutral , (and the regs still call the neutral a live conductor). 

    I have seen the result of a aluminum armour  installed around a large factory fence  for security lighting , a cold poured plastic T joint was made at each lighting pole with copper SWA cables to the pole lights, about 6months later what a mess having to break open the joints , copper to aluminum corrision don't  mix.  With old supply  copper overheads between houses now being changed to aluminum ABC's but with the existing copper service drop from the power company's aerial power lines still being used , I predict some trouble in years to come and neutral faults.

    Below is the inners of a double pole switch socket.
