I need to identify the neutral wire with the 4th switch to install a smart switch.

single junction box wiring multiple circuits
A junction node cannot be included in multiple junction boxes. A junction node also cannot be included in a junction box path and an individually created path between two segments (paths without a junction box). Maximum 16 paths No more than 16 controllable entry/exit paths can pass through a single-junction node within a junction box. Well, you can have as many junction boxes you want, technically, because the code limits the terminals, not the path to the terminal. Ad I recall, a circuit should have a typical load of 80% of the breaker max, so: A 12 ga/20 Amp line can run .8 x 2400 = 1920w.
If you are in a 3 phase panel, and you have circuits 2 4 6 sharing a neutral, you have 3 different phases sharing the neutral, each is 180 degrees out of sync with each other, each phase cancels out the other when the loads are balanced. So if each phase has 10 amps on it, the neutral will have 0 amps on it.All the wires contained in a box must come from the same source. You cannot mix voltages, or panels. Brb with a reference. Edit: 12-904 is actually for conduit. Whoops. Still, don't put 2 different sources in one box.

Commented Aug 15, 2021 at 13:34. 1. A box with a splice isn't required, but you can't feed a receptacle directly, a disconnect switch is required. A bigger problem is you can't have multiple feeds from the same system to a detached building. Now you could have two halves of a duplex receptacle, one switched, and of course two feeding cables have to come feed them. Someone may have forgotten to break off the tabs between the receptacle screws which tabs produce the above condition. If the two feeds came as separate (hot neutral) cables then the tabs on both sides need to be broken. Would it be weird to have like 4 junction boxes chilling in the attic?
