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.
