Hi
The RCB on my Crabtree distribution board trips on a regular basis, once every other day. Over the last month I have tried to narrow down which circuit it is on by isolating the individual switches for the different circuits, but with no success - it has tripped out regardless of which circuits have been isolated.
I am reluctant to get an electrician in unless there is something they can specifically test on a circuit to pin it down.
It quite often trips overnight (cold, moisture, damaged wiring) but not exclusively so. I have a lot of computer equipment, but most of it tends to have wall warts which are not earthed so they would be unlikely to be the problem.
So:
1) Is it possible that it is a fault of the RCB itself?
2) If I got an electrician in, is there some equipment that is likely to pick up the earth leakage (my suspicion is that there is more than one fault).
3) Are there any devices I can substitute in place of the devices on the circuit board so that the individual circuits trip, not the whole lot
