The Key to Understanding Light Switch Wiring and Knowing What You Can and Cannot Do

White Wires and Light Switch Wiring

Electrical Question: I am trying to figure out how to finish my circuit. I have a 3 way switch controlling a light(in the middle) where the power(2wire) comes into the first gang box that has the leg going out to the light there. The other switch(on the other side of the room)has been wired to control this light as well using 3 wire. (The white coded as black). Using a double gang box for this second box, I’m trying to add an additional single pole switch and continue power to control another light, but I don’t know where this light’s white return wire should connect to, because the white in the box is coded for hot (black).
