    I promised an update after mulling over the advice (and trying to get a few more measurements). I decided to follow the idea of a N-E fault. I did it all at 250v because I didn't want to try to unplug everything, even though (of course) I'd got all the power fully off. So one-by-one I pulled...

    Well I think what you said about getting reliable readings is key. I've got numbers coming out of my ears but no smoking gun. Today I can't reproduce the effect of reducing the overall leakage current (at the meter tails) by isolating the garage. And I can't provoke any fault to trip the RCD. My...

    I’d love to just rip it out but to spend the best part of a grand to narrow it down for fault finding seems a bit drastic. It may come to that... It’s T-N-CS by the way.

    I have a Crabtree CU so I think I looked for something that would plug in directly replacing the MCBs - seemed to be about £30 each

    I did consider that - until i saw the price of an RCBO - the board has 18 breakers...

    Well, you asked for details - sorry if this is too long... I have suffered random RCD tripping since I moved into this house 8 years ago. It happens infrequently - about once every 3 months on average - and I have struggled to find any pattern to it. Perhaps it is worse when the weather has...

    Qualified in electronics, only did electrical work as a DIY, now retired and enjoying life. Except when the RCD trips for no obvious reason... Cheers Jez
