[QUOTE="Mell, post: 505500, member: 33286"] To be honest on off I haven't read that bit in the book as I've never had a problem testing an RCD but the way I was taught was to use my metrel at the socket or accessory and do the RCD test and it would do the 6 tests but recently after being advised I did read up on RCDs and stood corrected it did say how to test an RCD off load, just a quick one, if you test an RCD off load and trips at 1 x load and trips at 5 x load as it should but then on half load it trips on the second cycle is that a defective RCD because it shouldn't and do the same test on the same board but on the other RCD and get a pass on the metrel. I think its a faulty RCD but I'm willing to be wrong. Thanks Mel [/QUOTE]
