Hi,
My parents house recently developed a lighting fault. Split load cu and the rcd tripped on one side, the only way we could get the rcd to stay on was to switch off the upstairs lights mcb. Switching on the mcb causes the rcd to trip.
So we went and checked everything obvious and no luck.
Bear in Mind the cu was changed 3 months ago and the electrician tested all the circuits and no issues.
So they got another electrician in this week, he was there for fifteen minutes and says he earth is incomplete on the circuit and this is causing the rcd to trip. The only option he gave was a complete rewire of the lighting circuit.
Can an incomplete earth cause an rcd to trip? I thought it would need a L or N to earth fault?
Just looking to understand and see if a re wire is completely necessary.
Many thanks
Neil
