In a failure, what position do both power check and powertrol fail in?

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

Answer: (C)

The question checks how these power-control devices behave when something goes wrong. Power check and powertrol are designed so that, if a fault occurs, the default or fail state is to keep the power path connected—so they fail in the Closed position. This design helps avoid unintended loss of power to critical systems by not disconnecting power during a fault. So, when a failure happens, you’re expected to see both in Closed, rather than Open, Neutral, or Locked.
