Have brought a masterseal plus double socket with rcd. Where I want to put it outside, there is a socket inside. What I want to know is how do you connect the existing interior socket to the outside one? Do I cut the cables that go to the inside socket and run two cables off that, one for the interior, one for the exterior? Or can I just add cables from the back of the interior socket and take them to the outside? Any diagrams drawn on paint or whatever would be go. Ive attached a diagram, can someone complete it please. Thanks
