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?
 
Looks like someone has tried to extend the ring when adding extra items.

Thanks for your prompt reply. To clarify, when you say 'tried' to extend the ring, are you suggesting that it isn't acceptable? If so what do you feel a better solution would be with this layout?
 
I would say it depends on where the 3 cables coming from the ceiling are connected. Maybe the ring circuit was extended to add the FCU (orange) and then a spur fed out from the jb (red)?.

I think further investigation/testing will be needed.

Yes, makes a lot of sense. I'll get a sparks to investigate before I proceed. Thanks again for your help DPG
