I'm wanting to run two banks of lights, both on their own switches, from the same breaker. Possible? So, I'll have two switches somehow powered by the same breaker, each running a different bank of lights. Can someone draw some type of diagram to help me?
Well if you can fix a broken helicopter, you can wire lights.
pattenp's diagram looks good to me. It's sometimes hard to pack a lot of wires into a wall box with two switches and three cables and several pigtails, so I suggest spending an extra buck on an "extra deep" box just because it's easier to work with.
If you are running 14/2 Romex on a 15A breaker, you should install no more than 1,440 watts of lights total.
If you run 12/2 Romex on a 20A breaker, do not exceed 1,920 watts total, and also do not exceed 1,440 watts on a single switch.
