Well, an EV Charger question has raised concerns over another aspect of an already fraught electrical installation!
My heat pump has a measured DC current leakage of 10ma so should require at least a Type F RCD. The PV inverter I have awaiting installation requires a Type A RCD. They will both co-exist in the same small CU, where from my inexperienced viewpoint cannot see how two RCD’s (Type A and B), SPD, and the three circuits can fit, let alone an EV Charger.
The heat pump manufacturer only published the DC spec and advised a Type F or B RCD this August. Prior to that they were silent on the matter (so I’ve no comeback on the installation company).
I think my EV journey has come to an abrupt halt. I wouldn’t have know any of this without your advice. Now to work on a solution……!
