Morning all
On xmas eve the RCD tripped. The CU has 2 RCD protected row of fuses. I flipped it back on and all ok. Then on Tuesday it tripped again. I have narrowed it down to the MCB that supplies a summerhouse. Yesterday I did some investigations. That MCB supplies power to the summerhouse and garage sockets. I removed the L and N for the sockets and the RCD tripped. I then reconnected the sockets and removed the summerhouse and all ok. So must be the summerhouse?
The SWA cable goes into the summerhouse into a socket. From that socket theres a T&E to an outside junction box that feeds some lights and an outside socket. When i disconnect that T&E, so the only cable connected to the socket is the SWA supply, all is ok. So I am guessing the problem must be the cable to the outside JB or moisture in the outside JB. The only doubt is that the outside JB appeared to be completely dry inside. I removed the cable feeding all the outside, and it still tripped, so I think I have ruled out everything and I am left with a problem with the cable to the outside JB. I was rained off yesterday so have not done anything else, but am I along the right lines? Cant see what else it can be.
Thanks in advance.
