Low and high voltage same raceway

[journeyman0217]

Running wires for a standby generator, generator requires power but also requires low voltage control wires to be ran to it. Are you allowed to run these wires in the same raceway, and if so can you please let me know of the code article where I can find it. Thanks in advance!

You need to determine what class control circuit it is.

Likely it is class 2 which the NEC prohibits running with power conductors.

Also the generator instructions likely require seperation.

If the control wiring is class I AND the insulation rating meets or exceeds the highest voltage it will be exposed to AND the control wiring is for the same or directly associated equipment as the power wiring, then yes. I have seen this with HVAC RTU's where the power and control wiring (120 volt class I) are run together.
