Out of interest, what do you do for a two gang switch? Do you use a three core and sleeve the black and grey or would you run a twin brown and a single?

Almost always twin brown for strappers and singles either end (presuming you mean 2-way).

Although some use 3-core, I would say the majority don't. Again, across the border the use of 3-core (or three-phase cable as they describe it) is not permitted.

I meant a 2 gang, 1 way. So I would run a three core from the rb4 to the switch, brown for common and black and grey for the two switched lives

With a 2-gang 1-way just a twin brown from one of the luminaires, and then a single to the other luminaire with the commons bridged in the switch.

Which wouldn't happen over here as we don't have sheathed singles available.
So for me it would be a three core to the switch from the rb4 and a twin to each light from the rb4

I wasn't aware of that. PVC/PVC single brown or brown & earth, or single blue (or unusually blue & earth) are readily available here.
 
point taken. shame as it's very useful for strapping the exhaust back up on a landrover. :oops:
 
Load o fuss about nowt. I hate old houses where the lighting circuit is wired in singles. Bloody cables slung about all over the place takes ages to work out what's going where half the time. Nothing wrong with using 3 core cables for 2 way lighting at all, in fact, best way. How do you lads go on with armoured then? Do you have specialised Brown Blue and Green/Yellow SWA?????

Not in the north, but in the south 3-core SWA is brown, blue & green/yellow. Although ETCI Wiring Rules permit the use of the armour as a cpc it is never actually done, and it wouldn't be permissible to remark the conductors on the SWA. (Except for recently it has been made legal to remark the blue as green/yellow with retrospective effect.)

In fact a job I did recently in Bridgend, Co. Donegal (right on the border - less than 5 minutes from me) needed a 3-core SWA. The local wholesalers didn't stock any in single phase colours so I had to drive to Letterkenny in Co. Donegal 20 miles away to get the cable.
 
You can get 3core swa here which is brown,blue, green and yellow. Its just not very common and generally a special order.

Granted, but unfortunately it's not always an option to wait for delivery!

And before anyone asks why not use 2-core - no-one stocks it!
 
Blimey my flabber has never been more gasted. Last time I was in Southern Ireland (Admittedly a while back now, on the West coast), we went into a local "shop", for some butties, it being a "general store". Turns out not only is it a general store and post office, but at the end of the room is a coffin resting on a table, yep its a funeral parlour as well, and to top it off, there is a couple of old boys supping the black stuff up the other end of the shop, this at 9:30 am. Fantastic, what a place. So I am amazed anyone gives a ---- about the colours of anything really!!! Hey ho.
 
LOL. Believe it or not electrical work has become much more regulated over the past two and a half years. Although the Wiring Rules have been around longer than that.
