In communication cables, what is the minimum bonding conductor size required for metallic members?

The correct choice is related to the requirements for bonding conductors in communication cables, which are vital for ensuring safety by reducing the risk of electrical shock and fire hazard. The bonding conductor connects metallic components to the grounding system, providing a path for fault currents.

The minimum size for bonding conductors is typically guided by standards and codes related to electrical safety. In this context, 14 AWG is recognized as the minimum acceptable size for bonding conductors in many communication cable applications. This size ensures sufficient conductivity to safely handle fault currents while remaining flexible and easy to work with.

Selecting a conductor that is too small may not effectively carry the potential fault current, which could lead to overheating and failure of the equipment or even potential dangers to personnel. Therefore, adhering to the established minimum of 14 AWG is essential for the safety and functionality of systems involving communication cables.
