What I am wondering is if there is any code that is violated if the wrong colors are used in wiring outlets? For example, it is standard to use white as neutral and black as power but if I only had two blacks or some other color combination, does this violate any codes in the state of Michigan?
A follow up question which is what made me wonder this... I currently have a light in a closet that has a pull chain for the switch. I want to install a switch outside the closet that will control the light fixture instead (with a new light fixture that won't use a pull chain). The existing power is of course ran to the light. Is it perfectly legit to simply use a single 14/2 or 14/3 wire (in one conduit), running the white and black to the switch, one for return and one for going? I know many outlets use black and black going to the switch so is it a big deal to use black and white instead? Does it violate any codes in Michigan?
