    Sorted it

    Just disconnected one of the earth leads at the back of the second socket and no RCD trips. I've made sure that the sole earth lead connected to the socket is indeed going to earth with a multimeter so unless I have missed something I think that's it but I'm not holding my breath.

    If all continues well I'll check out how the BPS performs later in the weekend - always assuming there is no loud bang and a smell of burning

    No, not a problem really. It’s just that when I had dedicated mains at my old place it took me some time to get a decent earth using a ground spike so I was going to be sensible for once and say don’t mess about with it until you’re satisfied current runs to ground. I got a fairly nasty jolt messing about with the last set up.

    The whole problem with the world is that fools and fanatics are always so certain of themselves, and wiser people so full of doubts.

    Good news I'd check that you have approximately 120V of AC on both Live & Neutral relative to earth & 240V accross from Live to Neutral & you are good to go

    Something definitely not right here Mark - I thought it was to good to be true

    240v across live and neutral
    BUT 240v live to earth and 0v neutral to earth

    Doesn't look balanced to me

    Have you reconnected the Earth on the secondary of the transformer to mains Earth?

    Sometimes my own stupidity amazes me

    That's exactly what I did wrong.

    All sorted now - 240V across live/neutral

    120v across live/earth & neutral earth.

    I am really grateful for your help Mark - esp previous post.

    Thanks
