What should be done if a grounded conductor is found to be faulty?

When a grounded conductor is found to be faulty, the appropriate action is to investigate and repair the fault in the grounded conductor. The grounded conductor, often referred to as the neutral wire, plays a crucial role in providing a return path for electrical current and maintaining safety in the electrical system. If this conductor is faulty, it can lead to unbalanced loads, potential overvoltages, and can pose serious hazards like electric shock or fire.

Repairing the fault ensures that the electrical system can operate safely and effectively. It is critical to address the issue right away to prevent further complications, ensure safety for users and equipment, and adhere to electrical codes and standards.

Other choices, such as replacing only the ungrounded conductors or isolating components without fixing the grounded conductor, do not adequately address the inherent risks posed by a faulty grounded conductor. Leaving it unfixed until the next maintenance could lead to serious safety threats, making timely repair essential in maintaining a safe operating environment.
