A 125 volt DC motor is rated at 10 kW. What is the current rating of the motor?
Official USCG Answer & Rule Citation
Correct Answer: Option B — 80 amps
Motor current rating is derived from power divided by voltage (I = P / V). Converting 10 kW to 10,000 watts and dividing by 125 volts yields exactly 80 amperes, complying with 46 CFR Subchapter J motor sizing guidelines.
