"Opened Ground"

"Opened Ground" refers to areas of a power system, such as electrical circuits or switchgear, that are intentionally disconnected or de-energized to ensure safety during maintenance or repair. When equipment is "opened," it means the circuit has been physically or electrically separated to prevent the flow of electricity, reducing the risk of electric shock or equipment damage. Properly marking and managing opened ground ensures technicians can work safely and verifies that the circuit is truly de-energized before proceeding with any work.
