Mains circuit tripping
I know this is electrical rather than computer but I was not sure which other part of Pprune to post in to pick the brains of the Ppruners.
Last night in the middle of dinner the circuit breaker for the sockets in the main part of the house (we have an extension with its own distribution board). I switched off and unplugged everything on the ground floor and reset the trip. The switch tripped again. I turned off the ground floor trip. And reset the main trip and all was OK. I switched back on the ground floor sockets trip and the main trip switch tripped again. I am now looking at a series of extension cables running from the extension and upstairs to power the boiler, fridge and freezer and of course the broadband router and wondering where to look next before I have to call an electrician in.
Can anyone help. Why is the main trip tripping rather than just the one for the groundfloor. The main trip is 80A RCD the ground floor is a 32A. Two thoughts have occurred to me.
1) the ground floor trip is faulty
2) it is the RCD that is tripping and some water has got into a socket or cable - heaven alone knows how I find that one.
Any suggestions would be gratefully received. At least the beer is still cold and the easter weekend decorating has been put on hold.
