Another time you'd use white as a hot is a 240V circuit.
Unless, of course, you want to run 12/3 (unneeded expense)and have an unused white at the load. You would/should have to land the white at the panel though, if you did that. I have seen 6/2 WG that has black and red wires (there is some in my house), but I have never seen it for sale myself. So, I don't know if it is even available anymore.
Good point.
Remember this thread is really about saras and her newbie question.
Most common wiring methods are in the MC and NM families so most jobsite and "what is on the truck" methods will utilize these; and most MC and NM is 10/12/14 gauge. I would hope folks doing conduit runs wouldn't choose to use white for an ungrounded.
Sara, do you understand 3 and 4 ways and how switch legs are done in the (2) basic uses they get?
