When should a cable exposed at a fault location be handled?

The correct answer emphasizes the necessity of grounding and ensuring that the cable is de-energized before handling it at a fault location. This approach is crucial for the safety of personnel working on or near the cable. Grounding the cable helps to discharge any residual voltage and reduces the risk of electric shock.

In addition, ensuring that the cable is de-energized means that no electrical current is flowing through it, further enhancing safety. Handling a cable under these conditions minimizes the potential for accidents or injury that can occur if someone were to come into contact with a live or improperly grounded cable.

This set of precautions aligns with established safety protocols in the electrical industry and ensures a systematic approach to dealing with potential hazards.
