Define "bonding" in electrical systems.

The term "bonding" in electrical systems specifically refers to the practice of connecting different parts of an electrical installation to establish a common ground potential. This is crucial in ensuring safety by reducing the risk of electrical shock, providing a path for fault currents to flow to the ground, and minimizing differences in voltage between conductive parts that may inadvertently become energized.

By bonding, all metal parts that are not supposed to carry current during normal operation are connected to a common grounding system. This ensures that if a fault occurs, such as a short circuit, any excess electricity is safely directed away from individuals and equipment, significantly lowering the risk of electrical hazards. The process also helps in reducing electromagnetic interference, contributing to the overall reliability of the electrical system.

This understanding confirms why the correct choice involves establishing a common ground potential through bonding, which is a fundamental aspect of electrical safety and system performance.
