# How Many Amps Does A 100 HP 3 Phase Motor Draw?

## What size breaker do I need for a 7.5 HP 3 phase motor?

Re: Wire and breaker size for 7.5 hp motor You need 50 amp rated wire with a 50-100 amp breaker..

## How many watts is a 1 hp motor?

746 wattsOne electric horsepower is equal to exactly 746 watts.

## How do you measure a breaker for a 3 phase motor?

For 3-phase loads, you divide the VA by the nominal voltage and by the square root of three (approximately 1.732). If your total 3-phase load in a 480V system is 50,000VA, what size breaker do you need? 50,000VA ÷ (480V × 1.732) = 60.2A. The next size up is 70A.

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

A 20 amp breaker is all you’d ever need for a 220v 3HP motor. It wouldn’t hurt anything to run 30amp circuits if you so choose, but it’s overkill.

## How much power does a 20 hp motor use?

14,914 wattAt 20 hp, P = 20*745.7 = 14,914 watt.

## How much electricity does a 5 hp motor use?

Therefore, the power consumed by a 5 HP motor performing at 80% efficiency will be: Output mechanical energy: 5 HP X 746 Watts = 3,730 Watts or 3.73 kW. As the output mechanical energy is the result of the motor performing at 80% efficiency, the power consumed by the 5 HP motor will be 3.73 kW X 100 ÷ 80= 4.66 kW.

## How do you calculate amps from HP?

The conversion from amps, a measure of electric current, to horsepower, a measure of power output by a motor, can be done using a fairly simple formula. Thus, horsepower is equal to the current in amps times the voltage in volts times the efficiency times the power factor, divided by 746.
