Last night, we lost all power to the plug sockets, the RCD had tripped. I isolated it down to the garage as if I turned off power to the garage (from the main CU in the house) the RCD could be re-set. As soon as I restored power to the garage the RCD tripped again.
I went out into the garage and turned off the small chest freezer in there and tried to restore power - it still tripped. This morning I turned off the small CU in the garage and tried to restore power and it tripped again. We have some outside lights and also a weather proof plug in the rear garden.
We had some gates fitted on Friday. The power to the garage runs along the fence and then goes underground to the garage where the post for the gate has been concreted in. On Friday they did trip the power as they had all there drills plugged into an extention taken from the garage. Once it tripped on Friday, it re-set fine and they then took power from the house. I am now thinking worse case scenario and they have somehow nicked the cable whilst digging and possibly damaged it, hence it constant tripping even though nothing is plugged in. I am presuming the cable is SWA although just had a look at the cable as it enters the garage and there is no writing on it what I can see. The cable is black, about 15-20mm diameter and is very rigid.
If there is no way of damaging SWA, would else could I try to isolate the problem and restore power back to the garage without it tripping the RCD?
TIA
