Hi, I am not an electrician but thought I would ask the experts. I had a major leak in the roof of my garage which was just above my consumer unit. Now eveything was working fine prior to the leak and the switch/trip feeding the garage tripped (obviously) with the leak.
I disconnected every circuit in the consumer unit (marking where each one goes first) and then using a hair dryer (fed by extension from hallway) I began drying each one out, it took a couple of days to do (after solving the roof leak), but they all seemed dry. I have a cheapie circuit test meter which I used to check if, when I swithched each of the individual trips/switches on/off they would show that when I switched on they would show on and vice/verser as they should so using my circuit tester.
I thought they had dried all ok so re-connected each one and switched back on the mains from the main feed in the house.
All OK with everything awiched off in the garage consumer unit, now I switched on the main one in the garage marked '63A 30mA' (I was told this would be the 'feeder' for the box by an old electrician I know that I see when walking my dog), and it switched on OK and stayed on.
Now when I try to switch ANY of the others on inside the consumer unit, the one marked '63A 30mA' switches itself off (but the main trip/feed inside the house which looks like all the others stays on).
Now I thought I'd be clever and disconnect all of them bar one (which fed sockets on the left hand side of the garage) after switching off the mains from the house.
I then switched on the mains again and the 63A 30mA one in the box and then the one I had left connected, but the 63A 30mA one in the garage tripped out. I tried this process for each one inside the box, having only one connected each time and I had the same result for all.
It has been two weeks since I had the roof fixed (by a neighbour who is a roofer luckily) and around 10 days of drying them out has passed so does this mean they still may be damp or does it mean they cannot be dried and once they have been wet they all have to be changed?
Thanks.
