[QUOTE="TonyCE, post: 183811, member: 7556"] Any Neighbours (with RCD protected installations) reporting anything similar problems. I've had a similar experience recently: One of the two RCD's tripping, no MCB's tripping, happens at night (between 11pm and 4am). Moved the Fridge and Freezer to another RCd, does not follow, ramp test showed 27Ma for both RCD's, and the one that was tripping was fine on 1/2 times, 1x, and 5X. Recent (10year old house) on TNCS. Have good IR on all circuits, rings all check out fine. No shared Neutrals. Neighbour said their alarm was occasionally resetting, and they'd had something done to prevent this. There is some heavy industry in the area. Still at a bit of a loss, but have swapped the two RCD's around to see if the fault follows. The rate of tripping has reduced from almost daily to "not for the last 5 days". [/QUOTE]
