I have a dead end 3-way switch in a 2-gang box. The switch is fed with a 14/4 cable using black as common, red and blue travellers, and white as a capped neutral per code. I would like to add a standard 2-way switch to this box with 14/2 running to a fixture. I would do this by pigtailing the black/common and white/neutral of the 14/4.
Any issue with this?
