A blue tag is used for which of the following conditions?

A blue tag is specifically used to indicate a "Reclosing" condition on electrical equipment. This tagging system is critical for safety and operational procedures, as it informs personnel that the equipment is in a state where it may automatically restore power after a fault or interruption. The blue tag warns operators and linemen to exercise caution, as the equipment has the potential to switch back on without a manual directive. Proper tagging is essential to prevent accidental re-energization when workers are performing maintenance or testing, ensuring that they are aware of the potential risks associated with the equipment's status. This proactive measure helps maintain a safe working environment in the field.
