[QUOTE="toontoonizer, post: 503743, member: 33054"] We have a large residential property (27 acres) with 2 powered annexes, gate motors plus lighting. One annex is fully featured with kitchen + boiler + underfloor heating hence the draw could exceed 100amps in certain scenarios. The internal wiring was one of the things I considered, but during the time they were repairing the first fault we were put on a generator and we experienced no voltage drop issues on the generator. If the internal wiring was an issue this would have persisted even while running on a generator. I believe the supply loop impedance is what indicated a fault to them the first time as it was around 1.2 (and I believe the maximum should be 0.8ish). Thanks for the reply 🙂 [/QUOTE]
