Hi
I have a powerbreaker rcd fitted outside my bathroom protecting my whirlpool bath, when i press the test button, i hear a humming noise from the rcd, but it doesnt trip?
I have checked the wiring as best i can, there is a 6mm earth going back to the fuse board which had a 100ma rcd, but i cant seem to find why the unit wont trip
any help or guidence welcome
