    Tripping Shower

    I have a 9.5kw shower running from a 40 amp rcb. About 10 minutes after turning the shower off the rcb trips. This has only just started, the shower has been in since we moved in. There is no pull cord switch, or rocker switch for the shower. Any thoughts why this might be happening?

    Nearly fifteen years ago I moved a bathroom in our house, and repurposed the 32A electrical shower circuit to power a pair of double sockets - which then had multiway adaptors powering all my office hardware (i.e. low overall power). Not exactly complex or risky at the time, and the MCB has...
