How do you convert HP to amps?

How to convert horsepower to amps? Hp to amps formulas

1. Single-phase AC. I = P * 746 / (V * PF * η) ;
2. Three-phase AC, line-to-line voltage. I = P * 746 / (√3 * V * PF * η) ;
3. Three-phase AC, line-to-neutral voltage. I = P * 746 / (3 * V * PF * η) .

### How do you calculate amps on a motor?

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.

What size breaker do I need for a 10 hp motor?

Full Load Current: Three Phase AC Motors

Motor Horsepower Size Breaker
5 230V 460V 15 15
7-1/2 230V 460V 40 30
10 230V 460V 50 30
15 230V 460V 70 40

## How many amps does a 460 volt motor have?

Full load currents for 460 volts, 230 volts and 115 volts motors – single and 3-phase 1 115 volts motor – single-phase : 14 amps/hp 2 230 volts motor – single-phase : 7 amps/hp 3 230 volts motor – 3-phase : 2.5 amps/hp 4 460 volts motor – 3-phase : 1.25 amps/hp

How to calculate horsepower and amps for a motor?

Amps = HP × 746 V × η × PF. Thus, the current in amps is equal to horsepower times 746 divided by the voltage times the efficiency η times the power factor. For example, let’s find the current draw in amps of a 1 horsepower motor that runs at 120 volts with a 90% efficiency. Amps = 1 HP × 746 W 120 V × .9. Amps = 746 120 V × .9.

### How to calculate hp to amps in DC Circuit?

HP to Amps calculator is used to calculate the amperes from horsepower of the motor is known. You can use the Electrical calculator to find the current in single, 2, and 3 phase motor circuits as well as in dc circuits. In DC circuits amps is the ratio between the product of HP * 746 to Voltage times efficiency.

How to convert horsepower to Watts in a calculator?

Horsepower (HP) is a measure of electric power equal to 746 watts (W). Converting horsepower to amps can be done in a few simple steps, or using this simple formula. Amps = (Horsepower × 746) ÷ Efficiency ÷ Volts. Continue reading to see how this formula was derived. The first step to convert HP to amps is convert HP to watts.
