If an electric motor with 80% efficiency is pulling 16A at 120V,
what is the horsepower?

Going by (16)(120)(0.8)/746, I get about 2 HP.

Is this right?


I also mostly agree based on a chart I have here.

2 HP AO smith 120V motor pulls:
16.4 to 16.6 at 3600 RPM
17 to 17.8 for 1800 RPM


Thanks Joe, that is in line with my measurements as well.
