Under which condition is coaxial cable allowed to share raceways with power and other circuits?

Under which condition is coaxial cable allowed to share raceways with power and other circuits?

• A. Separated by a barrier
• B. Any time
• C. Only if the power circuit is non-powered
• D. If the coaxial cable is shielded and the power is minimal

Answer: (A)

Sharing a raceway with power and other circuits requires a clear physical separation to prevent contact, heat transfer, and electrical interference between the conductors. The only condition that allows this is having a barrier inside the raceway that keeps the coaxial cable physically separated from the power conductors. That barrier ensures safe, code-compliant coexistence of the two systems. Without a barrier, sharing is not permitted, even if the power is low or the coax is shielded. Shielding or reducing power does not substitute for the needed separation, and simply being low-power does not eliminate safety or interference concerns.
