Re: Control wires in motor lead conduit?
Gary,
It is likely that the code will permit that installation. We would have to know more about the nature of the control circuit to be sure. However, if the run is very long and has a few 90s it is also very likely that the #14s would be damaged while the wire is being installed. There is just too much difference in size between the 1/0 and the 14s. I won't install #14 control wires in the same raceway if the power leads are larger than #4.

I can't think of any reason the code would prohibit such an installation but as another poster pointed out you are better off using larger control conductors and/or larger pipe to reduce the possibility of damaging the small conductors.
