What is the main goal of electrical system bonding?

The primary goal of electrical system bonding is to interconnect conductive parts and reduce shock hazards. Bonding involves connecting various metallic parts of an electrical system to ensure they are at the same electrical potential. This practice minimizes the risk of electric shock by providing a low-resistance path for fault currents. In the event of a fault, such as a short circuit, the bonded system allows the current to flow safely to ground, triggering protective devices to shut down the power, which helps to prevent injuries and equipment damage.

Focusing on system safety, bonding helps to create a unified ground reference, which is crucial in maintaining safety within electrical installations. This effectively reduces the risk posed by unwanted voltage differences that may occur between different parts of the system.

The other options do not address the core objective of bonding. Increasing voltage across circuits or enhancing system efficiency does not relate to safety and shock hazard reduction. Isolating electrical appliances serves a different function and does not contribute to the safety aspect that bonding specifically targets.
