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.
