I watched the test, it was only on the ramp test. 37ms at 30mA, 13ms at 150mA. The electrician thought it was marginal and was expecting to see around 18mA (he reckoned that Crabtree did tend to be sensitive and I think he was a little surprised to see it trip on 15mA rather than after). He was...

OK, had a qualified electrician round, ripped the consumer unit wiring out and organised it to fault trace and I now know I don't have to rewire for a long time, got rid of two faulty sockets. Took a long time! Basically the RCD on a ramp test was firing at 15mA. Running 5 PCs and a raft of...

Ah, so my month was not well spent on the basis that the trip switches do not isolate both sides of the circuit. Bah! Perhaps I just better get on the phone.

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...
