Can a 22 guage 6 conductor shielded cable rated at 300 volt be ran in the same conduit as
#12 thhn that is used for a 120 volt circuit. Pipe fill is not a concern.

Maybe, it depends entirely what the conductors are doing.

If you are trying to run a data line in the same conduit as power wiring most likely no you can't.
 
I agree with Bob,

If the twisted pair cable is a Class 2 or 3 circuit or a data or communications circuit then it can't be installed in the same raceway with power or lighting circuits.

If the 22 ga. stuff is Class 2, then no. You also may have signal integrity issues with them bundled with the 120 volt power.
 
Would 300.3.C.1 apply here? If not a Class 2 circuit, then yes.

BTW, would Class 2 wires be marked 300V?
