Rcd fault not tripping Discussion ThreadRcd fault not tripping Electrical Advice
Hi
I have only had a quick look at a fault so haven’t gone too far into it.
Lighting mcb tripped out, elderly lady wanted it checked out before it went back on so meggered it, all lights worked but rcd would not trip.
It’s a BG 3+3 split load installed by someone when the heating was done about 8 years ago, no paperwork.
Swapped the second rcd for one I had on board but still would not trip, plugged tester in first rcd and both tripped.
circuits are
Rcd
Cooker
Water heater - 2 twins
Sockets - 4 twins
Rcd
Sockets 4 twins
Garage - swa
Lighting - 4 twins
Is this likely to be a neutral in the wrong bar? No continuity between neutral bars when Rcds are off.
Any ideas where to start first?
