Marine Electrical Systems USCG Question #996 (Set 34)

When the control handle is in the 'off' position, what is the status of the solenoid actuated brake of an electric winch?

Official USCG Answer & Rule Citation

Correct Answer: Option B — de-energized and the brake is set by a spring

Fail-safe electric winch brakes operate via a spring-applied mechanism. When the master switch is centered in the off position, the brake solenoid is de-energized, allowing heavy compression springs to firmly clamp the friction brake drum and hold the load.
