Question 469Deck General70% to pass
If an attempt is made to hoist a load that exceeds the capacity of an electric winch, an overload safety device causes a circuit breaker to cut off the current to the winch motor _______________.
AI Explanation
The correct answer is C) after the line pull exceeds the rated winch capacity.
When an attempt is made to hoist a load that exceeds the capacity of an electric winch, the overload safety device is designed to cut off the current to the winch motor only after the line pull exceeds the rated winch capacity. This is to prevent damage to the winch and associated equipment. The circuit breaker is not triggered until the load exceeds the rated capacity, rather than at 99% of the capacity (A) or immediately (D). A short build-up of torque (B) may occur, but the circuit breaker will ultimately trip once the rated capacity is exceeded.
