There's plenty of horror stories of sockets melting. I personally wouldn't want to rely on a 3 pin long term but each to their own

Fair, but 10amp isn't exactly high is it? Mine is an outdoor on a dedicated radial. I can replace it about 20 times before it comes close to the grand PodPoint want lol.

Hows the RCD protection implimented? If it was installed for general garden use then it is more than possible that its sharing a type AC RCD with other circuits which should be avoided, its not allowed for a installed wall box, but is a blind spot where the socket is installed for general use rather than specially for vehicle charging. I'd also want PEN protection if its not implimented in the mode 2 charge cable, although I am dubious of how effective the single phase schemes* are which generally just work on the voltage drifting outside of an allowed envelope (where-as the three phase versions can re-derive a star point from the phases and compare that against neutral and earth)

*I've seen a PEN fault where the voltages at the fuseboard where absolutely normal, however as a result of resonably high impedance LV earthing at the pole-pig LV transformer, and a fault in another installation to a steel structure resulted in a voltage divider arrangement with the ground being held at a point between star point and one of the phases, rather than close to the star point. Luckily no electric car, but shocks off pipework when stood on the concrete floor:eek:

Now I know how my clients feel when I use any IT terminology.
