## What is the full load current of a 1 hp motor?

For single phase motors, NEC table 430-148 gives 230 Vac full load current of 8 amps for a 1 HP motor.

## How do you calculate amps from motor HP?

How to Convert Horsepower to Amps

1. Amps = (Horsepower × 746) ÷ Efficiency ÷ Volts.
2. Watts = Horsepower × 746.
3. Watts = Wattsη
4. Amps = Watts ÷ Volts.
5. Amps = HP × 746V × η × PF.
