Yes but he also needs and earth and neutral:-)


D'Oh!

(I'd thought "with the 18th an EV charger he might well need a local
earth rod anyway so..." but then went full prat.)


The single phase unit I fitted at a school had a local earth rod. I
still had to export the house earth to protect the cable and isolate it
inside the charger.

The neutral I believe had two purposes. One is to allow you to charge a
non three phase EV and the other is to provide 230V for the control
gear/interface on the charger.
