The IET is carrying out some important updates between 17-30 April and all of our websites will be view only. For more information, read this Announcement
Do the regs allow the use of a 3 core and earth cable for 2 switched lives or must 2 twin and earth cables be used?
Unless it has changed, and it has been a few years, 1neutral, 2 lives and 1E , so long as both light switches are fed from the same breaker.
In singles brown, black and oddly purple sometimes used. in terms of cable more like our T and E, you do get "funf-adrig" or 5 core, NYMJ 5-1.5mm , now in the new 3 phase colours plus neutral and earth.
