Rcd

[Andybhoy]

If fitted a split load board in a house with 2 floor extension, when all work was complete the board was powered up everything was fine until an appliance was plugged in, but here's the confusing part the regardless what Rcd was used (1or2) it would only trip (1) if all circuits were on but if u switched all circuits off the as the appliance was on turned each circuit on there would be no fault. Really need answers as this is a first for this type of problem
