Question 302Electricity & Electronics - QMED

The correct answer is D) thermal overload protection and low voltage release. The potable pump drive motor requires thermal overload protection to prevent damage from excessive current draw, and low voltage release to disconnect the motor in the event of a voltage drop, preventing it from restarting unexpectedly when power is restored. This is in accordance with U.S. Coast Guard regulations for the protection of electrical equipment on commercial vessels. The other options are incorrect because magnetic overload protection is not required for this type of motor, and low voltage protection would only disconnect the motor and not provide for a controlled restart when power is restored.
