A motor has a connected load of 11,190 watts. What is the horsepower of the motor?

To determine the horsepower of a motor when you have the connected load in watts, you can use the conversion factor where 1 horsepower is equal to approximately 746 watts.

To convert watts to horsepower, you would use the following formula:

Horsepower = Watts / 746

Plugging the connected load into the formula:

Horsepower = 11,190 watts / 746 watts per horsepower ≈ 15.0 hp

This calculation shows that the horsepower rating of the motor is approximately 15. Therefore, the correct answer, which reflects the closest standard motor size that corresponds with the given load, is indeed 15 horsepower.
