Coaxial cables entering buildings must be separated from lighting conductors by what distance?

Coaxial cables entering buildings are subject to specific installation practices to ensure safety and reduce the risk of electromagnetic interference. The requirement for separating coaxial cables from lighting conductors is critical to prevent any potential electrical interference that could affect the performance of the communication systems, as well as to enhance safety by reducing the risk of electrical faults causing hazards.

The correct answer indicates that a distance of 4 inches is mandated between coaxial cables and lighting conductors. This separation distance is established by guidelines that aim to provide adequate spacing to mitigate interference and potential electrical issues, while still being practically feasible for installation.

This standard ensures that the electromagnetic fields produced by lighting conductors do not adversely impact the performance of the coaxial cables, which are sensitive to such disruptions. Following these guidelines helps promote the integrity and reliability of both lighting and communication systems within a structure.
