When working across energized lines, what should be done to the circuit breakers on the hot line?

When working across energized lines, blocking the automatic reclose features of circuit breakers is crucial for safety. The automatic reclose feature is designed to re-energize the line after a fault is cleared, which can pose a significant risk to personnel working on or near the line. If someone is engaged in maintenance or troubleshooting activities, the sudden re-energization of the circuit could lead to severe injuries or fatalities. By blocking this feature, workers ensure that the circuit remains de-energized for the duration of their work, enhancing safety and allowing for proper procedures to be followed without the risk of unexpected re-energization.

Maintaining a safe working environment when dealing with energized lines is vital, and blocking automatic reclose functionalities is a standard safety procedure that helps prevent accidents and protects workers.
