## How do I convert HP to amps?

Converting horsepower to amps can be done in a few simple steps, or using this simple formula.

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

## How much current would a 1.5 HP 240v motor draw?

## What size breaker do I need for a 7.5 hp motor?

You need 50 amp rated wire with a 50-100 amp breaker. 7.5hp=40 amps x 250%=100 amp breaker on #8 Thhn. If a 100amp breaker isn’t sufficient to start the motor without tripping I can then go up to a maximum of 400% of the motor rating.

## Can amps convert to horsepower?

Multiply amps by volts to obtain the motor’s wattage, or watts (A * V = W). … Divide the wattage by the conversion factor 746 W per HP to convert watts to horsepower. The equation would be as follows: (W) / (746 W per HP) = HP. In our example, (575 W) / (746 W per HP) = 0.75 or 3/4 HP.
