PME vs TT for charger

garywwess
Can someone please explain in common scence English (this has to be explained to a customer) ..  why it is permissible for a street light , which in itself is basically a big metal earth rod buried 5 feet in the ground.. is allowed to be PME`d  (customer used to install street lights) yet his charger has to be TT`d  and isolated from the PME at all costs..  his parking space has a street lamp smack in the middle of it ???  I neither agree or disagree with the instructions to do so… just need something in writing to show the customer to prove im not just generating extra income needlessly..

    I think there will need to be a sea change on network investment at all levels,  at the moment it seems to be about keeping the existing network running as long as possible, and just filling in the hot spots.

    However if cars are to be charged in large numbers, like say half the fleet of cars we now have as petrol become electric, then we will need more power generation, an uplift of lots of routes to higher wattage, perhaps 33kV where currently there is 11kV, and an awful lot of new LV cabling.
