In the power check and powertrol scenario, which position do they fail?

• A. Open
• B. Neutral
• C. Closed
• D. Locked

Answer: (C)

During a power check, you’re confirming you can remove power from the system, so the powertrol must be in a non-energizing position. When the powertrol is in the closed position, the circuit is completed and power is still being supplied. That defeats the purpose of the check because you’re not verifying de-energization. The other positions (open or neutral) indicate no power flow, allowing the test to pass, and the locked position is a safety measure to prevent moving the control while work is done. So the scenario fails when the powertrol is in the closed position because it leaves the system energized.
