Bonding establishes a reliable connection between metal parts, ensuring that they have a low-resistance pathway for electrical current to flow. This is vital for safety in electrical systems, as bonding minimizes the risk of electric shock and reduces the potential for electrical fires by allowing stray currents, such as fault currents, to safely dissipate into the ground.

Reliable connections are also essential for the proper operation of electrical equipment and systems, as they prevent differences in electrical potential that could lead to unsafe operating conditions. In contrast, other types of connections, such as temporary, non-conductive, or loose connections, do not provide the consistency needed for safety and functionality. For instance, a temporary connection may not maintain integrity over time, while a non-conductive connection does not allow current to flow at all, rendering it ineffective for bonding purposes.
