hi, i have installed a ring main upstairs and one downstairs. the problem is my downstairs ring is tripping the rcd, i have checked all 9 sockets all cables are correct and earths insulated i have used a fluke to check the ring is correct and i do get continuity. can some body give me any advice.
many thanks james.
Have you checked Neutrals on same RCD supply as lives for ring? presume you have split load board with 2 rcd's
If not that then check for N-E fault, often front plate screw of socket pressing on N in back box,
