Hi folks, wondered if anyone has any help/comments to resolve this please?
Customer in 1970s hastily knocked up property with many extensions/DIY wiring jobs.
Way 1 on CU is wired into a B6 breaker and comprises kitchen and dining room. Way 2 is also wired into a B6 breaker and comprises the rest of the house. So far, so good.
Now comes the comedy. Opening breaker 1, circuit 2 energised all lights remain on. Conversely, opening breaker 2, circuit 1 energised-all lights remain on! Removing way 1 and we lose kitchen and dining room lights but way 1 line conductor is live and vice versa scenario for way 2. Obviously the seperate circuits have been bridged somewhere. I have TEMPORARILY for safetys sake (although I know still risky) put them both on the same MCB whilst I try and figure a way of trying to trace and remove the bridge thus restoring the customers original 2 radial circuits. Does anybody have any good methodical approach to diagnosing/doing this without resorting to going into the roof, pulling up and disconnecting every cable individually and getting covered in insulation a la abominable snowman? (yes, their eco friendly insulation monkeys have buried all the cables too but that a whole different can of worms...)
Hoping to hear from you guys-best wishes...
