Which conductor is used to equalize potential between SBBs on the same floor of a structure?

The BBC backbone bonding conductor is specifically designed to equalize potential between different service entrance points or structures, such as SBBs (Service Bonding Buses) on the same floor. By using a backbone bonding conductor, electrical potentials across different locations can be balanced, thereby reducing the risk of electrical shock and protecting equipment from voltage differentials that can occur due to various factors, including lightning strikes or electrical surges.

The use of a dedicated backbone bonding conductor ensures compliance with electrical codes and standards, which prioritize safety and functionality in electrical installations. This conductor not only serves the purpose of bonding but also enhances the overall performance of the grounding system within the structure.

In contrast, while grounding conductors are crucial for providing a path to ground for electrical faults, they do not specifically address potential equalization between multiple SBBs. Communication conductors are meant for transmitting information rather than for grounding or bonding purposes. Power conductors, similarly, are designed to deliver electrical power, not for equalizing potential. Therefore, the backbone bonding conductor is the most appropriate choice for this application.
