    Could the problem be that somewhere on the cable going from the pull cord back to the panel, a socket or something has been added.

    If the electrician simply connects the supply to the RCBO to the non RCD BUS bar in the panel, that might in itself stop the tripping. '

    That was the first thing to do. Connecting it as it has been connected, did nothing to show the problem any clearer for anyone here, and was the incorrect way to connect it anyway.

    He could have been lucky and happen to put in an RCBO a bit more sensitive than the RCD, but that would have been luck, rather than the proper independent connecting of the RCBO.

    I thought you replaced the cable? :confused:

    I replaced the cable from the shower to the pull cord, not from the pull cord to the panel.

    Have you access to inspect the cable from the board to the switch? i.e attic, side crawl attic?

    Push the test button for your socket rcd, then go try switch the shower on. If the shower doesent work and your rcbo isint tripped then it's clear what the problem is.

    No, but if need be, I could run a new cable. Strange that it trips only when the pull cord is on if the problem is from the pull cord to the panel.

    That the RCBO isn't connected independently of the RCD???

    Have you tried the experiment in post #95?

    So the rcbo is fed from the rcd.

    Did you run the shower for a minute or 2, or will that instantly trip the Rcd?

    I don't know. I'm a teacher, and everybody knows those who can't do...teach :pac:

    I did the test in post 95 and yes, with RCD tripped, and the RCBO not tripped, the power is off to the shower.

    The electrician you got to put in the RCBO for you is he qualified or is he someone from Mens shed?

    Turning off the rcd won't prove that, as both phase and neutral might be through rcd to rcbo. But running the shower causing instant trip would strongly suggest it alright if the shower had previously been running at least for a few minutes at a time.

    Turn on pull chord, then run shower.

    Does it run?

    Y would you connect an rcbo downstream of an rcd?

    No, the RCD tripped immediately, not the RCBO.

    You wouldnt, but it appears that is how it was connected today.

    A few earlier posts

    Did shower stay on when rcd tripped? If not then your sparks made a mess of adding dedicated rcbo.

    As I and others have said, the RCBO should have been connected independently of the RCD, so only the RCBO would trip with residual current problems.

    Adding in an RCBO onto the RCD was a pointless exercise if that is what has been done, in terms of stopping the RCD tripping if the shower was the cause.

    Looks like the electrician intended connecting the rcbo up independently alright, but connected into wrong neutral bar probably.

    The rcd tripping instantly bwhen you try to run it is a sign of that.

    But he said earlier it was running for a minute or two after the installation of the RCBO.

    That grey capacitor is not in place ATM, would that make a difference?

    I think he may have said it tripped a minute or two after switching on the pullchord. I'm not sure though.

    But you said in post #80 that it was running perfect without it connected :confused:

    Running the test that Bruthal suggested was the first time I tried running the shower since last week.

    Probably not.

    So to clarify. If you put pull chord on, the rcd will stay on for a time. But if you try to run shower, it will trip instantly?

    My bad, I should have posted that there was no current through the earth when the capacitor was disconnected. I didn't actually try running the shower. Just turning on the pull cord after post 80 made me realize that I had been a bit premature with my optomism:rolleyes:
