When working behind a recloser, what should a line crew do?

When working behind a recloser, the priority for a line crew is to ensure safety and coordination with the system operations. Calling dispatch for a hot line hold or Do Not Reenergize (DNR) is crucial because it alerts the system operators to prevent any unintentional reenergization of the circuit while the line crew is working on it. This safeguard helps protect the crew from electrocution or other accidents that could occur if the circuit were to be reenergized inadvertently.

This action is in line with standard safety protocols that govern work on or near electrical equipment. The crew's responsibility includes ensuring that all safety measures are in place to maintain a safe working environment before beginning their tasks. By notifying dispatch of the hot line hold, the crew is effectively communicating their operational status and ensuring that additional risks are mitigated.

The other options, such as resetting the recloser, notifying customers, or performing a system check, do not prioritize the immediate safety of the line crew working on the circuit and could lead to dangerous situations if the recloser were to activate while work is being performed. It’s essential for the crew to adopt practices that ensure their safety first when operating around high-voltage equipment.
