EV Charger
To enable the electrical earth to be tested, each of the three earthing points I have installed needs a breaker fitted. This allows the earth to be disconnected and tested then reconnected and tested to record (and approve) it resistance measurement.
Once I had installed it for the car park I turned my attention to the Tesla charger for the electric vehicle. Eventually it will be driven by the solar panels but for now I will plug it into the three phase supply. I need to order a plug.
