What is the purpose of an equipment bonding jumper in rigid metal raceways?

The purpose of an equipment bonding jumper in rigid metal raceways is to ensure proper grounding. Grounding is a critical safety measure that helps to protect both people and electrical systems by providing a safe path for fault currents. The bonding jumper connects the metallic raceway to the ground, which helps to ensure that any stray currents or faults in an electrical system can be safely redirected away from equipment and individuals.

In addition to providing a safe pathway for electricity, this bonding also reduces the risk of electrical shock and fire hazards. Proper grounding is essential for the safe operation of electrical systems and contributes to the overall reliability of electrical installations. This makes it fundamental for the maintenance of safety standards in both residential and industrial applications.
