Been toa job this morning and the customer (well gaffer) is complaining about nusiance tripping. Meggered it all, all fine (over 150meg for a10yr old installation). 2 rcd tested on auto 1 tested at 1x 17 and 5x 8ms. But the other one doesn't trip at all for the tester but trip about 3 or 4 times a day for no reason) I plan to replace it tomorrow (if I can get hold of a legrande rcd from anywhere)
But if it's not thus then what can it be. Also next door is suffering from the same problem which I've looked at and again the wiring is fine
Any ideas?
