    Sockets tripping after board upgrade - should have been rewired

    After updating a consumer unit, from an old rewireable fuse board, one of the socket circuits is tripping when under load. The property should have been rewired as the installation is so dated but the project manager and client didn't want to rewire it. The supply to the flat is approximately...

    CU 10m from incoming box - new dwelling

    Thank you for the advice all. I will use armoured. I meant ducting and for future proofing. If you ever wanted to pull something through in the future as it’s under a block and beam floor. I’m still not sure how people are working out 16mm SWA the calcs come out at 25mm surely? Unless anyone...

    CU 10m from incoming box - new dwelling

    A plastic conduit is laid under the floor ready for a cable. I want to use 25mm tails rather than armoured. Previously I’ve fitted 100amp SP&N fused switch with 25mm armoured but they are tight to make off in the mains electrical meter box and some providers don’t want you in there box! If you...
