Hi,
Does the NEC restrict mixing 120V (receptacle) circuits with 277V (lighting) in the same conduit?:?

Nope, they just need to be identified.

Nope, they just need to be identified.

But be careful if they feed devices (receptacle and switch, for example) in the same box.

Thank you the 277V light switchs and the 120V receptacles are in different boxes.
