SWMBO in her new kitchen extension has this idea of an Island in the middle which has the sink, dishwasher and a bit of other odd gubbins thereon, and a couple of extra 13 amp outlets on some power pole thing.
Now whilst the drains and water are arranged to go there, the power needs obviously to be tapped onto the kitchen ring main. This is up in the ceiling and as usual drops down where needed to the wall sockets as per normal practice.
However whilst I can take a cable down from the ceiling next to the drain pipe which will be boxed in, in due course, the cabling has to run under the concrete floor slab for a few feet before coming up inside the Island unit.
How would this normally be done?. I don't suppose its the done thing to just lay 2.5 T&E under the floor in the concrete so would it be better to either put in a buried duct in the concrete floor slab, or simpler still use some suitable 2.5 rated (2 lumps off to keep the ring main) SWA direct bury cable?.
Any advice appreciated..
Cheers...
