[QUOTE="Murdoch, post: 505372, member: 24445"] What paperwork? Fault finding is a huge part of this job and unless you understand the necessity to do the right thing in the right order you won't make any progress. Go back to basics - have you confirmed continuity of all the circuits on the "bad" side of the fuseboard? Have you IR'ed each in turn, with the CPC's connected to the earth bar? Are ALL the loads disconnected? What are the IR readings for L-N, L-E and N-E for each circuit? Remember with fixed loads such as boilers to turn them off at the local isolation switches .. and that is why isolation switches should always be fitted Tripping on 1/2 test suggests you have a fault [/QUOTE]
