I got called to a job this afternoon, it's outside lighting, about a 1000w of lamps on the whole circuit, and when trying to quote for it done a few calcs and the volts drop is massive, it's 24 volts, the circuit is run in 3 core 4mm swa, and is 300m in length, now I know that it's well over the allowed 3% allowed, but after reading into the regs a bit I've found a reg- 525.100 would this apply, the max measured Zs is 2.43 and is on a 10 amp rcbo, so given that disconnection times will be satisfied can I disregard the volt drop as safety is not affected?
many thanks in advance
