During pole setting near energized power lines, what are protective covers rated for line potential?

Protective covers that are rated for line potential are required during pole setting near energized power lines to ensure the safety of workers and the public. These covers are designed to prevent accidental contact with live electrical lines, which can pose serious risks including electric shock or electrocution. The requirement for protective covers reflects the need to adhere to safety standards and regulations that mandate protective measures when working in proximity to energized equipment.

By using protective covers, workers are not only shielding themselves but also helping to mitigate the risk of an electrical incident, making the working environment safer. This requirement is crucial for any practices or procedures involving tasks close to energized conductors, emphasizing the importance of safety precautions in high-risk scenarios. The other options, such as optional, recommended, and discouraged, do not capture the essential nature of this safety measure. The requirement clearly indicates that such protective equipment is not just a good practice, but a necessary one when dealing with potential electrical hazards.
