[QUOTE="ProDave, post: 382718, member: 6969"] Low L-N readings most likely mean there was something still connected, e.g the timer circuit of a bathroom fan (remember to turn off all fan isolators). That won't cause imbalance and won't trip an rcd. Low L-E or N-E readings are the ones that you should be suspicious of. there is one reading listed there that would have all of us pulling that particular circuit to pieces to find the fault. Can you guess which one it is. I would suggest you have NOT fixed the rcd tripping fault, it just hasn't happened for a bit but there is most clearly a fault on one of those circuits you tested.
