[QUOTE="SPECIAL LOCATION, post: 375938, member: 250"] To be quite blunt and honest... Without actually doing any RCD tests and Insulation resistance tests you have so far proved very little. RCD tripping suggests somewhere on one or more of the circuits that the RCD supplies there is a cumulative leakage greater than 30ma. This could be damaged cable, or some foreign object bridging some conductors.. (damp, dead rodent, nail through cable etc..) Or it could be that the cables are all perfectly OK but there are some appliances with excessive earth leakage... Or it could be that the RCD is just over sensitive! ?? A martindale socket tester will not prove or diagnose any of these... Wrong tester for wrong problem.. bit like trying to find why my engines not firing correctly with a tyre pressure gauge... (wrong tool for that problem!) You need to go back and do some relevant tests on all of the circuits supplied by the RCD. and test the RCD.. Guinness [/QUOTE]
