    DPDT switching branch circuit from one breaker to another?

    I’m planning a 240V welder circuit in a detached garage with a 100A sub panel. For the 160A or 180A output welders I’m looking at, the conductor can be #10, and a 30A breaker is probably OK, but a 40 would help the duty cycle. Conductor must handle welder's 1eff rating, breaker can be up to...

    Shower on 4mm ring final circuit.

    Hi, I've got a customer who wants a 10.5 kW shower installed in his bathroom. As it happens he already has two unused 4mm T&E cables run from the CU cupboard to the loft. I know it's unconventional but is there any reason I can't use these cables to make a dedicated RFC for just the shower...

    Testing on internal light circuit

    Hi I know I have to do more testing but I just want to see if there is something I’m missing. Customer said light fitting in the loft was crushed causing the breaker to trip. I thought easy fault to rectify which was very naive of me. I arrived disconnected the damaged switch which was in...

Specifically, one outlet failed and then the second one went about a year later, with no trip of the breaker. How do I test the wiring to make sure it...
