I currently have the following circuit in a room:
I plan to add a ceiling light and was going to tie the light switches black and ground to the new ceiling wires black and ground, and then use a wire nut to cap the ceiling wires neutral and leave it in the box not connected to anything.
I know the NEC 2011 says a neutral should be in the box, but is a neutral even required in a lighting circuit? Is leaving the capped neutral from the ceiling wire in the box a problem? Or is a neutral absolutely required here?
In the diagram, the neutral in this circuit comes from the outlet, and a neutral used as a hot wire is connecting the single pole switch.
