Bonding electrical systems refers to the practice of connecting various conductive parts – such as metal enclosures, grounding conductors, and metallic structures – to ensure that they operate at the same electrical potential. This process helps to eliminate voltage differences between these parts, reducing the risk of electric shock and ensuring safety.

By establishing a conductive connection between these various components, any stray electrical currents can be safely directed away, minimizing the chances of equipment damage or electrical fires. Bonding also plays a crucial role in ensuring the effective operation of protective devices, such as circuit breakers and fuses, by allowing them to detect fault conditions accurately.

This process is an essential part of electrical installations and maintenance, as it provides a pathway for fault currents to safely dissipate. Bonding is distinct from grounding, which specifically refers to connecting an electrical system to the earth, though both practices are integral to electrical safety standards.
