Question:
Can you combine the 0 to 10 vdc signal wiring & the load wiring to a dimmable light fixture in the same raceway. A lot of the fixtures have only one entrance point & the wiring in the controller is not separated so all the wiring at those points are combined. Appreciate your input, thanks.

Answer:
Hey James thanks for your question. If the 0 to 10 volt "signal" is a Class 2 circuit, then no, separation is required as stated in 725.136. The power supply for that circuit would need to be listed as stated in 725.121(A). If it is a Class 1 circuit then yes as stated in 725.48(B). The luminaire manufacturer's instructions should provide details for the wiring.
