Due to a bit of a cock-up, a double socket in our utility no longer has a supply to it. I can access its cable (2.5mm) in the ceiling, but cant easily get this cable to a convenient place on the rest of the downstairs sockets ring. What I CAN access is the lighting radial that supplies the ceiling lights. I was thinking I could connect the socket to the lighting cable, knowing that the socket would need to be labelled as such and also that it would need to be rcd protected. However, as we use this socket for a 1kw microwave I am wondering if that would pull too much current for the lighting circuit. Is that so?
