Contents

## What size breaker do I need for a 200 hp motor?

So, assuming an inverse time breaker, the 200 hp motor would have a maximum branch circuit OCPD of 240 amps x 250% = 600 amp.

## How many amps does a 300 hp motor draw?

Here are the Full Load Amp (FLA) values for typical 230VAC and 480VAC 3 phase motors.

150 360 180
200 480 240
250 580 290
300 696 348

## How do I convert HP to amps?

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.

## How do you calculate full load motor amps?

The motor FLA calculator uses the following formulas:

1. Single Phase AC Motor FLA (Amperes) = (P [kW] × 1000) / (V × cos ϕ)
2. Single Phase AC Motor FLA (Amperes) = (P [HP] × 746) / (V × cos ϕ × η)
3. Three Phase AC Motor FLA (Amperes) = (P [kW] × 1000) / (V × 1.732 × cos ϕ)

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

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 full load amps on a motor?

Full Load Amps, or F.L.A., represents the amount of current the motor is designed to draw at the rated horsepower. In the example nameplate, this means that when the motor is running under a full load at 230 volts, we can expect it to draw 5.4 amps.
