The primary purpose of bonding together metal equipment enclosures and metal raceways is to?

The primary purpose of bonding together metal equipment enclosures and metal raceways is to keep all metal parts at the same voltage. This practice ensures that if a fault occurs, such as a short circuit, all bonded metal surfaces will rise to the same potential, minimizing the risk of shock to personnel and equipment. This is crucial for safety, as it prevents voltage differences that could lead to electric shock or arcing.

By ensuring that all metal parts are at the same voltage, the bonding provides a reliable pathway for fault currents to return to the ground, allowing overcurrent protective devices (OCPDs) to operate effectively and quickly. This synergy between bonding and the operation of OCPDs is essential for maintaining both safety and equipment protection, but the primary concern remains the equalization of voltage throughout the metal framework.
