I have a double gang junction box which will house two switches, one controlling main lights which are at 277V and the other controlling decorative lighting at 120V.
Can I run several circuits through the same conduit? I need to bring five individual circuits into my bathroom/dressing room addition. I'd like .Assuming the junction box has the proper capacity, I want to run a separate circuit through that box so as to split-off a circuit which will then go two different ways to power up an outlet on . So say you're running Class II circuit for a doorbell from a 16VAC transformer to the doorbell button switch and to the chime using 18/2 with .

So say you're running Class II circuit for a doorbell from a 16VAC transformer to the doorbell button switch and to the chime using 18/2 with insulation rated for 300V. You still couldn't run that wiring in a conduit with 120/240V power wiring. As long as we're talking about metallic conduit, you can indeed use the conduit as the EGC, and connect your cable ground wires at the junction boxes. The answer is yes a single gang nonmetallic receptacle or switch box is allowed to have two cables entering the same holes. See a copy of the NEC exception below; 370-17. Conductors Entering Boxes, Conduit Bodies, or Fittings.
From the statement above, for 120V & 277V circuits occupying the same enclosure, it reads to me that both 120V & 277V circuits can exist in the same enclosure, without any special separation. Is this true? yes with some exceptions for switches/devices supplied from 277 different legs or 277 and 120.
Multiple circuits are ok. The wires are all coming from the same panel, and they're all #14 120v, but they're coming from 3 different single pole 15 amp breakers. You would want to apply 12-3030. If they are from the same panel, they can be in . It's a 15A multiwire branch circuit supplying both 120v and 240v outlets. It's allowed to serve both line-to-line and line-to-neutral loads. The only requirement is to use a common trip double pole breaker and not independent trip single pole breakers with a handle tie. Can two different circuits go through the same junction box? That is, two cables enter from different breakers and they tie to cables exiting, but the two circuits aren't connected except for the grounds if that is required. Yes, that is fine. The only restriction would be mixing voltage classes.
