Which statement about communications systems bonding conductors is FALSE?

The assertion that bonding conductors must always be longer than 20 feet is incorrect. In fact, there is no requirement in electrical codes that specifies bonding conductors need to reach a certain length, such as 20 feet. Bonding conductors are used to connect different grounding systems and ensure they are at the same electrical potential, thus minimizing the risk of electrical shock or fire. The length of these conductors is determined by specific installation practices and requirements related to effective grounding rather than a fixed measurement.

On the other hand, the other statements are accurate in describing the requirements for bonding conductors. They must be protected from damage to ensure their integrity and functionality, can be installed in a straight line for practicality, and should connect to grounding terminals to establish a proper ground reference. Understanding the role and requirements of bonding conductors is crucial for effective grounding practices in electrical systems.
