## How do I convert HP to amps?

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

- Amps = (Horsepower × 746) ÷ Efficiency ÷ Volts.
- Watts = Horsepower × 746.
- Watts = Wattsη
- Amps = Watts ÷ Volts.
- Amps = HP × 746V × η × PF.

25 A | 3.62 HP | 90% |

## How many watts is a 1 hp motor?

One electric horsepower is equal to exactly 746 watts.

## How many watts is a 10 hp motor?

So a 10 hp motor will need 7680 watts when operating.

## Can a generator run an electric motor?

YES, but it can only be done long term with an electric motor that is designed to also run as a generator and if the generator will be paralleled with other generation the motor will need to be a synchronous motor.

## How much power does a 2 hp motor use?

How many watts does a 2 HP motors have? If a 2 horse power motor is doing 2 horsepower of work then in the load about 1500 Watts of energy is used in the load.

## 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.

## What size breaker do I need for a 3 HP motor?

## How do you convert HP volts to amps?

Given horsepower and volts, it is possible to calculate amps. The calculation of amps uses Ohm’s Law, which is amps times volts equals watts. Multiply the horsepower by 746 watts. For example, an engine at two horsepower with 230 volts would be calculated as two horsepower times 746 watts, which equals 1492.
