Morning all, looking at putting a distro circuit in. It's to feed a small room that the caretaker wants to use as a bit of a workshop. Without seeing the supply board et al in my head I originally thought SWA would be best. The supply board has trunking coming off it with plenty free room, which takes the cables up into the false ceiling. The cable run would then be in the ceiling void until the last 6 foot or so where it will need to make an appearance surface mounted in the back of a store cupboard. The cable won't go outside at all.

Just wanted a bit of confirmation really, am I right in thinking SWA is the best choice of cable or would you recommend something else?
 
Cheers, yeah, single phase. So basically the cable is going to come through the wall and straight in to the back of the remote board so it won't even be on show. I was then going to run sockets etc in PVC conduit from the remote board. Although I said workshop, I do mean the term loosely - it's going to be somewhere for the caretaker to charge power tools and also open up a hoover or two for repair.

Circuits will be RCD protected so I was quite content with PVC conduit - happy to be persuaded otherwise though.
 
a nice touch would be a few ft. of dado trunking with 3/4 double sockets back of the bench. you can get triangular profile to fit direct onto the bench itself.
 
I could get dado, but the last time I bought it, was about £30 a length I think. The bench isn't fixed either, so whatever I fit will be direct to the wall.
 
Depends on what's already there, what you can do, what it's going to be used for etc.
It might be that you can 'get away with' plastic conduit, otherwise steel. You may be able to just do the drops in conduit and run the rest in T&E above the ceiling.
You might need a separate circuit for testing and another one for charging batteries or powering his computer.
 
post #7 is assuming that the caretaker is not brain dead, and has a measure of common sense.

It's literally as I've said - he'll want to charge a few power tools and possible plug a hoover in to see if it works. Only other thing I've not mentioned (wasn't needed until now) is that there's asbestos in the ceiling so no access there. The lighting is going to need to be wall mounted bulkheads or batons for that reason. Don't let @Risteard hear you mention T+E outside the domestic sector mind!

Oh, in that case then... :)
 
SWA cable in this case sounds like overkill as it is never exposed to damage. The cable where visible is in a store cupboard, I can see no need to provide earthed protection unless you are managing RCD separation so I might just go for nyy-j or perhaps HD flex!
There is no need not to use SWA if it is convenient to connect into the boards easily but also no requirement to use it.
The plastic conduit for a caretakers workshop sounds fine.

Thanks - SWA might be a bit of a pain to terminate in all fairness. If I can get away with something of lesser protection I can utilise the existing trunking and bring it straight in to the back of the remote board.
 
50x100 trunking can be adapted with inserts to accept double or single sockets - makes a nice strong but simple install with end caps to enclose it.
 
I like NYY-J much easier than swa but the chances of getting the length you require instead of a drum is remote whereas swa you can often get a cut length.
