Wiring the following: power going to the first switch then to a second switch followed by 2 lights, then ending with a third switch. How would I wire this?
Yeah, if I had to do this job to the newest code, I would just avoid doing any switch loops on multi-way circuits, even if it makes the total run longer. I'm starting to think that eventually you're going to see 14/4 and 12/4 turning up at a lot of suppliers due to the new code.The above drawing is the way to do it except for one code issue. There is no neutral at the last three way switch. Neutrals are required in switch box by the current NEC code. Connect the lights at the last switch to be compliant.
Allan.,The 12-2-2 and 14-2-2 have two white wires allowing use for two independent circuits. (One of the white wires has a thin colored stripe to tell it apart from the other.) Use the old rule of marking the ends with colored tape or stain if you need to use one of the white wires as a hot wire. The 12-4 and 14-4 have one white wire, the other three are usually red, black, and blue.
Colored wires #6 and thinner may not be remarked with white tape and used as neutrals.
