Just want to check i'm reading things correctly.....
extending the ring mains in the garage, i want to put all the sockets cables in conduit to make it look better, and whilst i'm at it, replace the old T&E cables with singles in conduit for the lights, as they run zigzagging thru the roof joists, and have been used by the last owner to hang things from.
Singles cable is sold in 100 meter reels only it seems, i roughly worked out i'd have a 25 meter run for the sockets, and 10 meters for the lights, and to do it in blue, brown and green/yellow, i'd have to buy 300 meters of wire, (500 if i bought 2.5 for the sockets, and 1.5 for the lights)
I've read that you can use a single colour and sleeve it at each end/termination point, and label the CU to warn of this, and that you can use any colour wire you want except green/yellow, which must only be used for the CPD,
But you can use another colour for the CPD as long as it's sleeved appropriately,
is that correct?
i.e. if i buy a reel of 2.5mm grey singles wire, and some blue, brown and green and yellow sleeve, that'd be ok, as a single reel would cover all the wires i need, at every inspection point in the conduit i'd sleeve the wires just to make tracing them easier if needed one day, as well as at every junction/termination of course.
