How do you perform a one-shot operation on a recloser?

A one-shot operation on a recloser is a specific action that allows the device to interrupt power after a fault and then restore power automatically after a set time. In this context, pulling down the red handle is the correct action to take. This handle is typically designed to initiate the one-shot operation, enabling the recloser to trip and clear faults.

The design of reclosers includes safety features, and the red handle often acts as a manual control that overrides defaults for single operations, ensuring that the equipment can be managed effectively during maintenance or fault conditions. This understanding is crucial for linemen who must operate electrical equipment safely and efficiently during both routine tasks and emergency scenarios.

Other options may represent different functions or controls that do not pertain to the one-shot operation, and understanding the purpose of each control can help ensure that linemen operate reclosers correctly and safely.
