I have a couple of swich location questions that I haven't been able to find the answer to. For years now, I've always wired switches for clothes closet lights outside of the closet, and for basement furnaces, I've installed a cutoff switch at the top of the stairs of the dwelling. I do this because I was aalways told that you are supposed to, but I haven't been able to find any reference to this in the code. Are these practices listed in there, or do I not have to do this? Thanks!
