Hair salon project

[infinity]

Hi

Been asked to quote for a hair salon, brand new fit in an empty building, was just wondering as the customer intends on dry lining all walls and ceilings i was going to run basket above ceiling with T&E cabling as only 11Mx 9M, i was gong to drop cables with pvc conduit, into drylining boxes, this would mean RCBO's on most circuits, as switch drops would mean rcd protection as would sockets etc.,

I was only wondering if all the rcd protection could end up being troublesome? as dryers could trip them out etc, also i was going to put 2-3 sockets max on a ring supplying dryers due to the current usage of them.

thanks

Do lighting circuits need RCD protection if there is a 'skilled operative' working there?

If the switch drops are surface wired in say pvc conduit then lighting wont need rcd protection anyway.

you could do it all in MICC. :waving:

Ooooooo that's now a ''Specialist'' installation method!!!

I wonder how long it'll be before metal containment installation systems will come into the realms of ''Specialist installation''!!!!! Not too long me thinks!! lol!!

Just so we know where we’re heading, is this what is best or what is cheapest?

The cheap option will probably come out and bite you later.

But from your posts it looks like you’ve decided what you’re going to do anyway.

We all know that cheapest isn't always best, but cost is usually a factor.
In this situation what is the worst that can happen from installing basket and pvc conduit instead of steel conduit?

Perhaps the hairdressers enjoy seeing if they can throw their scissors into the ceiling tiles so hard that they hold there and there could maybe be the possibility of going right through the tile with such force that they go straight up through a hole in the basket (which will be around the perimeter of the room) and penetrate the cable sheath and insulation, then they could stand on some aluminium steps to go to pull the scissors out of the cable and get a shock because you had decreed that they were skilled and instructed people so the circuit didn't need rcd protection.

Personally I think this seems a bit far fetched - I reckon basket and pvc conduit will be just fine.

For any "young uns", time was when a spark had to be able to use all types of cable, and containment no matter what it was.
We used to have to be able to test our own work too, no relying on gadgies who had done 2391 because we had been taught how to do it it was expected of us
