BS 7671 does have another solution in Annex 722 for separation of the vehicle from the installation, if pockets are deep enough.And still this thread rumbles on.
Graham if you had a PME supply (could be single or three phase) and deep pockets (deep enough to have bought an EV in the first place) which method would you choose please?
Please also clear up what may seem to be an elementary question. I understand the need to separate the earthing arrangements of different systems, which could lead to difficulty placing either a TT earthing rod or a reference electrode. So does the separation have to be from a PME electrode (in my case, I assume that would be a street lamp by the corner of my property) to an installation electrode; or does it have to be from a service cable to an installation electrode?
