[QUOTE="Brobat, post: 453530, member: 28365"] I can't turn the whole installation off as its industrial. They wouldn't be too keen in me shutting the whole place down to test a faulty outside lighting circuit. I am aware that the regs state that the CPC should remain connected, The fault is that its tripping the dedicated RCD as soon as the timer sends power to the circuit. I've disconnected the L & N coming out of the RCD and applied power to it and it doesn't trip which suggests that the RCD itself is not at fault. however the CPC in question is the armour of some 2 core armoured flex which is connected on some trunking at a fairly awkward position to get at due to the amount of various bits of other lettuced that have been added over the last 20 years or so.
