A 125 volt DC motor is rated at 10 kW. What is the current rating of the motor?

Correct Answer: Option D — 80 amps

Direct current motor current is determined by dividing power in watts by voltage ($I = P / V$). Converting 10 kW to 10,000 watts and dividing by 125 volts yields 80 amperes. IEEE 45 guidelines require proper conductor ampacity sizing based on this full-load current rating.
