RCD not tripping at 0 Degrees

[dagrat]

Nuisance tripping is a general term that refers to many causes, but that would definitely include the tripping of an over sensitive red, so yes really.

test a range from below ma trip is, to above could be a 30 ma trip trips at 40 ramp test will tell you if it works or not

i just do it, do not need to think it is so easy i do not know the exact range in which individual meters work, if a trip does not work on a standard test or trips at 50%, i would do a ramp test on 30ma trip set at 30 on ramp test , meter will then start at 0ma and rise to maybe 50 or 60 ma. If it trips at 50ma, you can say it is tripping out of range and is faulty, if trips at 20ma, it is under range and faulty, if it does not trip at this setting, i would turn it up to 100ma if trips , still over range and faulty, if does not trip, trip is more than likely ffffeeeddd. so you know what to write on the ecr
