What is the best way to run a new 15 Amp circuit for 4 groups of light in 4 areas A (1 bulb), B (1 bulb), C (8 recessed lights), D (4 recessed lights). Since drywall has not been installed in ceiling or walls, I have a lot of options to run the wire for wire this circuit. The arrangement of the rooms as follows: A B C D Power feed (panelboard) is closest to A, then C then B and then D. A is a room and will have its switch near door. B is also a room and will have its switch near door. C and D are open areas separated by a stair. C and D will be controlled by 2 adjacent dimmers mounted to wall at the bottom of the stair. Thanks in advance.

I am adding some new curcuits to a panel box. I do not have any new knock outs to use. I have thought in the past that per code you can only put (1) NM cable thru a connector, but the bag of 3/8" NM connectors I have says "For one or two 14-2 to 10-2 nonmetallic sheathed cables". Which is correct? Thanks Jeff
