A
Answer:
Hey Wayne thanks for your question. Yes, you can with some limitations. In general, all conductors of the same circuit must be in the same raceway, auxiliary gutter, cable tray, etc. as stated in 300.3(B). That is the method usually used. But if nonferrous wiring methods are used, and the heating issues caused by induced currents in 300.20(B) are addressed, they can be run in different raceways, etc.
