RCD is MEM 100A 30ma RCD - *with 3rd earth tail* connected

Try disconnecting the earth flying lead. However, I suspect that your faulty
RCD premise may be correct, unless there is a serious wiring fault with the
house. But this worked before, didn't it?

that doesnt rule out all sorts of unsavouries though... and if N
connection is connected to E... I wouldnt be surprised at anything
much. Its remarkable what can actually work!
