[QUOTE="Phoenix, post: 539987, member: 8133"] Your PFC is going to be a lot higher than your PEFC on a TT system, remember that PFC is the highest of PEFC and PSCC, seen many certs for TT installs witha comically small PFC filled in! For PSCC, 2 lead high, test between neutral and each phase (3 tests) and take the highest and double it to acocunt for a ph-ph fault. I expect the reason you weren't getting 7-8A for PEFC is chances are with your earthing conductor connected back in, you have parrallel paths, and the zdb is probably quite a bit lower than Ze/Ra OOI, whats the overcurrent protetcion for the SWA?
