Hi,
We just had what we thought was a power cut. All the electrics cut out, until we realised it was the main circuit breaker which had tripped. None of the individual circuit breakers had tripped, just the main.
I turned them all off again, flipped the main breaker on, and then one by one switched the circuits on. The main breaker tripped when the circuit marked 'upstairs lights' was switched on, indicating a fault with that circuit.
This has happened once about 2 years ago, when terrible stormy weather caused a leak which passed through one of our loft extension light sockets and tripped that circuit. The problem stopped when the weather stopped and the light dried out and we've never had such bad weather again. This time, we have not had any significant rain or wind for days.
But what we have had, is really, really cold weather (-7 at night). Our car doors have been frozen shut, the outside tap is frozen inside, that sort of thing. I mean, it's warming up during this afternoon, but could the cold weather have caused this?
Or could it more likely be something else?
Thanks
Matt
