[QUOTE="ProDave, post: 316563, member: 6969"] Okay, where to start? First circuit, IR N-E 25M ohm would not trip an RCD even if one was present. High R1+R2 start looking for a dodgy light switch on the light fitting you tested at. Second circuit: R2 open circuit, start splitting the ring at each socket and test to identify which leg of the ring has the open circuit CPC. then investigate and fix / replace that leg. [/QUOTE]
