What does a system bonding jumper connect?

A system bonding jumper plays a crucial role in establishing a safe and effective electrical system. It specifically connects the grounded conductor, which is typically the neutral, with the equipment grounding conductor. This connection is essential for maintaining a low-resistance path for fault currents, ensuring that any fault condition can effectively trip protective devices and minimize the risk of electrical shock or fire.

The bonding jumper is designed to ensure that all conductive parts of the electrical system are at the same electrical potential, reducing the likelihood of voltage differences that can create dangerous shock hazards. By connecting the grounded conductor to the equipment grounding conductor, the system bonding jumper helps ensure that equipment and systems are properly grounded and bonded in accordance with electrical safety standards.

Understanding this function is critical, as it is part of the overall strategy to enhance the safety and reliability of electrical installations. This connection is pivotal in grounding schemes, serving as the first line of defense in managing ground fault conditions.
