What is the purpose of bonding in electrical systems?

The purpose of bonding in electrical systems is to ensure electrical continuity. Bonding creates a low-impedance path for fault currents, which is critical for the safety and functionality of an electrical system. This practice connects various conductive parts in an installation, including electrical equipment and raceways, to prevent voltage differences between them that could lead to dangerous conditions.

When bonding is properly implemented, it minimizes the risk of electric shock and helps ensure that circuit breakers and fuses operate effectively during a fault condition. This means that if a fault occurs, the electrical current will be directed through the grounded pathways, facilitating prompt disconnection of the faulted circuit.

While enhancing accessibility, improving energy efficiency, or increasing load capacity are important considerations in electrical installations, they do not directly pertain to the core function of bonding. Bonding primarily focuses on safety and the effective operation of the electrical system by ensuring that all conductive components are at the same voltage potential, thus protecting against hazardous scenarios.
