I'm revamping the kitchen electrics, 1980's property. Majority of the sockets have a couple of cables going in/out of them, with the only exceptions being a couple of sockets tee'd off fused spurs and fed by single cables. However, I'm perplexed by one area. By the side of the gas hob there was a two gang socket, above that a wall cupboard and above that a junction box which fed a fused spur which in turn supplied a wall extractor. Stripping back the ceiling plasterwork revealed a pair of 2.5t&e cables coming through the a hole in the joist. One of this pair went to the j/b, the second to the f/s. A single 2.5t&e which runs along the joist from the other side of the kitchen also comes down from the ceiling and went to the j/b. Finally there was a further cable between the socket and the f/s.
I want to use the f/s to supply an island extractor, and retain the socket. I assume that the j/b was effectively performing the function of an unfused spur, but my question is: what was the purpose of the cable between the socket and f/s?
