In electrical systems, what does "bonding" ensure?

Bonding in electrical systems is a critical process that involves connecting various metallic parts to ensure electrical continuity and enhance safety. This practice is essential for preventing potential electrical shock hazards, reducing the risk of fires, and ensuring that all parts of an electrical system are at the same electrical potential.

When metallic parts, such as conduit, panels, and enclosures, are bonded together, they create a low-resistance path for fault currents. This allows protective devices, such as circuit breakers or fuses, to activate quickly in the event of an electrical fault. By ensuring that all metallic components are connected and at the same potential, bonding helps protect both individuals and equipment from electrical hazards.

Proper bonding is also a requirement in electrical codes and regulations, emphasizing its importance in maintaining a safe electrical system. The benefits of bonding in terms of safety and performance illustrate why this concept is fundamental to electrical installation and maintenance practices.
