I wonder if someone could offer some advice.
Over the last few days the fuse has been randomly blowing in the upstairs sockets in my house.
As I said, it is completely random and happens regardless of whether an upstairs socket is being used or not. I've isolated the problem to one socket, as this is where the 'pop' with a blue flash occurs before the fuse goes. I've checked the wiring on the socket and everyone is connected okay.
Could there be a problem with the way the wires are laid under the floorboards?
Any suggestions would be great
