Table C.12. Type EB PVC Conduit -- Table C.13 .The wire I'm using is 12 AWG stranded. The junction boxes are metal and sized at 4 x 2 1/8 deep. Additionally, the J boxes are just connection points. . (hot/neutral) that enter the J box are counted as 1. Example two complete Romex wires enter the box, one from the left and one from the right. There are then 2 hots, 2 neutrals, and two .
There is a guideline based on the number of conductors and gauge. A normal single outlet box can only have two pieces of 12-2 in it where I live. The cubic inches is stamped on the box somewhere. PS- if you didn’t know this, you may be in over your head. And yes, that 12-2 is like a coat hanger and very hard to work with.

OR main panel wire enters on the south of the box, and 1st subpanel enters on north, 2nd subpanel enters on west of the . For example, a 4-inch square box that is 1 ¼-inch deep can accommodate up to eight #12 wires, nine #14 wires, or ten #16 wires. In contrast, a 4-inch square box that is 2⅛-inch deep can hold more wires. . In summary, . If I put a junction box in the ceiling, is there a maximum number of 14 guage wires that can be connected together with wire connectors because there would be 6 wires connected together (and is there a maximum number of wires per box). Coming into the juntion box would be: - one 14-2 wire used for a switch and 3 recessed lights(65 w each)

Hello, I have a room in the basement that has incoming 12/2 Cu from a junction box feeding to a light, then 12/2 fed to another light, then 12/2 run to a combination switch/recept. I would like to wire this setup so that the switch operates independent of the receptacle, so my plan is to run 12/2 from the junction box to the switch/recept combo .Piped to and installed junction boxes on the ceiling between each square of 4 lights, then did individual whips down to each light. They were all 0-10v dimmable, so I was using luminary MC cable that is the the #12 120v wires and the dimming wires in 1 cable, and I wasn't going to struggle getting 2 of those in each light.
A junction box provides a code-approved place to house wire connections, whether for outlets, switches, or splices. . The size of a conductor is expressed as AWG (American Wire Gauge); the smaller the number, the larger the wire. Common household wiring is usually 16, 14, or 12 AWG.
