Need to know what the control wiring is controling. If it is Class 1 wiring and it is functionally associated with the power wiring there is no problem having it in the same raceway as long as the insulation on all the conductors has a high enough rating. If the control wiring is Class 2 then it can not be in the same raceway with the power wiring without a barrier. 725.26(B)(1), 725.55(A)
