Before re-energizing, what should you confirm about the lockout?

• A. The lockout device is removed
• B. The circuit breaker is in ON position
• C. Lockout is intact and no voltage is present
• D. The panel is closed

Answer: (C)

Before re-energizing, you must confirm that the lockout device is still in place and that there is no voltage present on the circuit. The lockout keeps the equipment de-energized, and a proper zero-energy check using the right tester verifies there is no residual or stored energy that could cause harm if power is restored. Only after this confirmation should you proceed to re-energize. Removing the lockout would defeat protection, turning the circuit breaker ON would bypass the lockout, and simply closing the panel does not ensure the circuit is truly de-energized.
