In grounded systems, how should non-current-carrying conductive materials be connected?

In grounded systems, non-current-carrying conductive materials should be connected in a manner that establishes a ground-fault current path. This connection is essential for safety in electrical systems. When a fault occurs and a conductive path is created inadvertently (such as when a wire comes loose or insulation fails), having a ground-fault current path allows the fault current to flow back to the ground. This helps to ensure that protective devices, such as circuit breakers and fuses, can detect the fault and interrupt the circuit, reducing the risk of electric shock or fire.

Establishing a ground-fault current path ensures that any fault current will be directed safely to ground rather than allowing it to energize non-current-carrying conductive parts, which could create dangerous situations. By connecting these parts properly to ground, you help facilitate the correct operation of protective devices, maintain electrical safety, and minimize potential hazards in the system.
