    well looking at the picture the bus bar covers both rings the neutrals for these are in opposite neutral bars that would cause the problem

    it looks to me that 1 RFC has it's N in N bar 1, and the other RFC has it's N in N bar 2, but they are both on the RCD.

    the Outgoing live terminal of the main switch is feeding all the breakers directly via the buzz bars .
    the rcd is being fed from its top and bottom terminals as its conected to the already live buzz bar and also being fed by the flylead from main switch to the top.
    however if you follow the current path of the second ring main the neutrals are connected to the right neautral bar so its only route out is via the N of the RCD! hence the rcd trip fault .
    if that makes sense???

    looks like something set up by rogue traders to catch you out quoting a rewire for £9000 to an elderly couple. no spark could call himself a spark after doing that!

    Perhaps this could be moved to the CU installed for £150 thread,as this is what i would expect to see and no bonding,cert etc,it was done by dave down the boozer after 8 pints of stella,shocking.

    I dunno if it's my eyes, but it looks to me as if the busbar has been cut. It looks as if the busbar feeds circuits 1 and 2 directly from the main switch, and circuits 3, 4 and 5 are supplied from the RCD.
    However the neutrals from circuit 3 (assuming correct sequencing) have been connected to the neutral bar that is not on the RCD, so any introduced load on this circuit would trip the device.
