Coaxial cable may be placed in raceways with other power and communication circuits only if which condition is met?

• A. Separated by a barrier
• B. Running without any separation
• C. In a nonmetallic conduit
• D. Shielded by a metal jacket

Answer: (A)

When coaxial data cables share a raceway with power and other circuits, a physical barrier that separates the circuits is required. That barrier keeps power conductors from being in direct contact with or too close to data cables, reducing electromagnetic interference and maintaining safety and code compliance. Simply running them together without separation can cause signal degradation and code violations. Using a nonmetallic conduit doesn’t automatically create the needed separation inside the raceway, and shielding on the coax itself does not substitute for a proper barrier between different types of circuits. So, the only condition that makes concurrent use acceptable is having a listed barrier between the power and data conductors inside the raceway.
