In a bathroom remodel I'd like to add another, separately switched, light fixture. Now there is a 3-gang wall box (or there was till I ripped out), controlling the existing ceiling light fixture, a heat lamp, and an exhaust fan. The box currently has 6 cables:
1 each for ceiling light, heat lamp, and fan 1 incoming power 2 going to downstream lighting fixtures (presumably)I know from having done this in another bathroom (same house) that I have to install a new deeper box, both to get a place for the new switch, and to get more volume to meet code requirements for wire count. I plan to use the Carlon blue plastic, deep old-work boxes.
Now to the questions:
- Should I replace the 3-gang with a 4-gang, two 2-gangs, or a 3-gang and a 1-gang?
- What is the best way to deal with the aluminum copper issue? The question is complicated because I'm using two dimmers and a timer that are not available in the CO/ALR form. Last time I wound up pigtailing practically every wire in and out of the boxes.
TIA
