What is the primary purpose of an electrical bonding jumper?

The primary purpose of an electrical bonding jumper is to create an electrically conductive path to ensure electrical continuity. Bonding jumpers are crucial in grounding and bonding systems, as they connect different conductive parts to establish a low-resistance path. This minimizes the potential differences that can occur between various conductive surfaces, thereby reducing the risk of electric shock and ensuring the safe operation of electrical systems.

By maintaining continuity between metallic parts, bonding jumpers help to facilitate the effective operation of protective devices, such as circuit breakers and fuses, which rely on detecting ground faults or overcurrent to function correctly. Proper bonding also enhances system reliability by preventing stray voltages and ensuring that all parts of the electrical system are at the same ground potential, thereby promoting safety and equipment protection.
