[QUOTE="Evans Electric, post: 493261, member: 1408"] The owner of a local plant hire firm has asked me about ...in his words ...a 400V supply to a car charger ( On the phone I thought he was talking about an electric fork truck) can use one of the welder sockets ? etc . I see many articles which seem to out lining reams of difficulties we need to jump through , including taking one of the many courses available , last one £400 for the day . Am I being silly by thinking we install a 30A X 400V X 2 or 3 phase supply to the charger supplied , nail it to the wall in the bloke's parking space and switch on .? Apparently we are supposed to notify the DNO for their records. I've read about earth rods . Clamping the vehicle to earth . Fitting special RCDs that detect harmonica playing DC currents from travelling back into network etc etc . Surely all protection is within the charger . [/QUOTE]
