Hi, first time posting on here so apologies in advance if I ramble on a bit.
I have a fault on my mains as the fuse keeps blowing every time I switch on power at the mains. I was told there is probably a fault on the circuit and that to isolate the fault I would have to go from socket to socket, taking out a red and blue wire and switching power back on. If fuse doesn't blow then the circuit is ok up to that point. To try this I switched off power at the mains and removed the circuit breaker. I unscrewed the socket cover and tested the socket and there is still power going to it. My tester is lighting up like a Christmas tree.I would welcome any advice on this matter.
