Occupancy Sensor Wiring in same wiremold as 120V

[steve66]

I need to add some occupancy sensors to some existing lights. The occupancy sensors have a 24V power supply, and send 24V to a relay to switch the power to the lights.

Per the NEC, is there any way I can run the 24V wiring in the same wiremold with the 120V branch circuit for the lights?

I thought that somehow I could reclassify the low voltage equipment, and do this. But I can't find it in the code.

Thanks in advance.

Perhaps you are refering to Section 725.52(A) Exception No. 2.

This is just my opinion.
If it's wrong, we'll both find out.

If the 24V power supply transformer is rated at 1000va or less, I would classify it a Class I power limited circuit. NEC 725.21(A)

If all of the conductors have insulation rated for the highest voltage in the circuit and are "functionally associated" with the equipment being powered (and it sounds like your's is) , then 725.26(B)(1) allows all of the conductors to be run in the same raceway.

Wire fill and de-rating are applicable.

Hope this helps
