Hi
A friend of mine recently had seven white plastic double mains sockets repl aced with metal looking sockets. After about a month of this being done the RCD that covers these sockets started to trip soon after switching on the TV. I checked the sockets with a tester and it identified that in three of the sockets the neutral had been connected to live and live connected to ne utral. The TV was connected to a correctly wired socket. I rectified this w iring error in the three sockets and the problem appears to have gone away. As I understand it, this wiring error should not have tripped the RCD and for a month this was the case, but yesterday the RCD dedcided to trip out s everal times within minutes of switching the TV on. This would point to the TV being at fault, but since the wiring correction in the sockets all is w ell again (so far anyway). Any views welcome.
