hey guys, I was wondering what the code is for a dwelling as you come in the door of a room what is the max distance that a switch for lights can be away from the door? One more thing, when strapping mc cable is it legal to use a one hole strap as a mechanical connection to the wall and then use a black tie wrap or steel tie wire around that one hole strap to secure a bundle of mc cables running in a wall as a means of strapping and support?
