Fault has stumped me!!

Do you mean submain to elsewhere or are you refering to contactor supply feed?

Boydy - i may've mentioned it in my original post but there is an RCBO board that feeds several submains (i thought thats what they are called - they don't have their own DNO fuse if that's what you are asking )around the common parts of a large block of flats.

I rewired that one light so it is on the correct switched live , neutral and earth now.

The place is a total wiring mess!!!

So is the rcbo tripping now sorted?

Haha good question. Not sure. Still have to replace 6 lights then i'll check. They had a non-existent IP rating so had to be done anyway. I'll let u know monday. For once i have sat AND sun off and i plan to put work woes out of my mind for 60 hours!

Ps whoever suggested clamp meter for earth leakage cheers. I'm gonna do that too.

Its all wired in the same size for cpc and neutral so N to CPC short no problem right?! JOKE
