When can multiple clearances be issued on a single circuit or line?

Multiple clearances can be issued on a single circuit or line when any crew that requires one can have one. This approach ensures that all personnel working on or near the line are properly safeguarded and aware of the electrical work being conducted. Issuing clearances to all necessary crews improves safety by allowing each crew to operate under the assurance that the circuit is de-energized and that it is safe to work.

In practice, this means that if multiple teams need to perform work on the same line, each can secure their own clearance, ensuring coordination and communication among the teams and reinforcing the importance of safety protocols in electrical operations. It fosters a culture of safety and accountability, where each team is responsible for their own clearance.

The other choices suggest limitations or conditions that could hinder effective safety practices or may not account for the collaborative nature of electrical work, which is critical in ensuring that all crews are appropriately protected while performing their tasks.
