Pyro Help Please

Has the OP measured any Insulation resistance? As numerous posts have mentioned it could be a fault at a fitting or being a lighting circuit a borrowed neutral.

Had a quick scan thought the full thread but not seen anything mentioning test results.

First of all me thinks he had a problem with the lights and left them to the end of the job because thats what you do I suppose and because it is MICC and it has been in for a while it may be an end that is down or the insulation is brittle and the cable it touching the box and its not the first time a customer has connected the earth of a fitting in with the neutral.

Also fuseboard change you cannot do a full EICR but I always do a Ze PSC and global insulation ie live and neutral linked out and IR at 250vdc to earth if I get 80Meg fine if I get dead short I highlight to customer more work is required. Plus I dont give them my readings ie customer phones to say I have another electrician quoting and he has asked me to ask you what your reading were I always reply I cannot put my hands on them just now but I could call back later to which i never do and they dont either. In other words if the guy wants to know what the reading are he can find out for himself
