It would be good to see a bypass on the RCD, so the supply authority chap could, if the RCD wont hold, make a judgement call about whether to bypass it or to give householder a temporary board with a few sockets on it
We would probably look for an alternative but a non RCD version would be a No No.
It does beg the question if a property is causing the RCD to operate, on the safety of that installation and weather we should re-connect the mains supply after repair.
I suspect that we would issue a notice of deviation telling the customer to get their installation checked.
