Hello everyone, I'm a bit concerned because the electrician has mounted a double socket on the back of the kitchen cabinet. The backing is only a 4mm board as a normal kitchen base unit. The socket is NOT attached to the thicker 18mm back brace. The unit is only 300mm wide. The socket is for the built in gas hob and oven. The wire comes out of the wall behined the oven, then is run through the edge of the oven unit and the 300mm unit and enters the socket from behined the cabinet and through the 4mm board. Is it safe to mount the socket on this thin board? surely the screws holding the socket would or could come loose. Some expert advice would really be appreciated as I can't question the electrician.
