When coaxial cables are run underground, they must be separated at least _____ inches from underground light and power conductors, unless in a raceway.

The requirement for coaxial cables to maintain a separation of at least 12 inches from underground light and power conductors is rooted in safety standards outlined in the National Electrical Code (NEC) and best practices for minimizing electromagnetic interference and ensuring the integrity of both types of conductors.

This distance helps to avoid potential electromagnetic interference that could affect signal quality in coaxial cables, which are often used for data transmission, such as cable television. It also provides a safety margin to protect against accidental contact or damage to the cables during maintenance or excavation activities.

Maintaining this separation is crucial for preserving the functionality of communication systems while ensuring that the electrical systems remain safe and reliable. In scenarios where cables are run in a raceway, the requirements can differ, reflecting the increased protection provided by the raceway itself.
