The main bonding jumper is the correct term for the screw that connects the neutral bar to the service equipment enclosure. This component is crucial in electrical systems as it ensures that the neutral conductor is properly bonded to the grounding system of the service equipment. This bond plays a significant role in providing a defined path for any fault currents to safely return to the ground, thereby enhancing safety and preventing the risk of electrical shock or equipment damage.

The function of the main bonding jumper is to help maintain the same potential between the neutral and ground conductors, reducing the risk of voltage differences that could lead to hazardous conditions. It is a vital aspect of ensuring the integrity and safety of the electrical installation as per the National Electrical Code (NEC) requirements.
