[QUOTE="GD16, post: 519931, member: 33818"] Hi just a quick question, when you test the Earth loop impedance on a EV charger where the EV is on its own TT Rod but the feed comes from the TNCS at the CU what do you call the test for the Earth loop impedance ? (eg Ze for the EV point) I assume you would test between the incoming Line in the EV point and at end of earth cable connected to the Earth rod . Thanks for any help I know the chargers that need TT are being replaced by EV chargers with PEN fault protection but was curious. [/QUOTE]
