What is the purpose of electrical bonding?

The purpose of electrical bonding is to ensure electrical continuity and safety between metal parts. Bonding involves connecting conductive parts to create a low-resistance path, minimizing the potential for voltage differences that could lead to electrical shock or equipment failure. This is especially important in environments where metal parts are present, such as in electrical installations or equipment.

By bonding these parts, any stray voltage that may accumulate on non-current carrying metal parts can be safely dissipated to ground, enhancing the overall safety of the electrical system. This process also helps in reducing electromagnetic interference and ensures that in the event of a fault, such as a short circuit, the circuit protection devices will function properly by allowing sufficient fault current to flow and activate the breaker or fuse.

Grounding serves a similar but distinct purpose, focusing more on the safety of devices rather than the connection between metallic components. Increasing voltage is unrelated to the concept of bonding, as is merely connecting a circuit to a power source.
