What size breaker do I need for a 1 hp motor?
How to Calculate How What Size Circuit Breaker a Machine will Need:
| HorsePower of Main Motor | 220 Volts, 1 phase | 220 Volts, 3 phase |
|---|---|---|
| 1 Hp | 5.6 Amps | 2.8 |
| 2 | 11.2 | 5.6 |

| 4 | 22.4 | 11.2 |
How do you calculate amp draw on a motor?
You can usually find this information listed on the product label, or in the owner’s manual. Then you take the wattage, and divide it by the voltage (100 watts / 12 volts = 8.33 amps.) This will tell you roughly the amperage your equipment will draw.
How many amps does a 1 hp motor draw at 120 volts?
Common Horsepower to Amps Conversions
| Horsepower | Amps | Voltage |
|---|---|---|
| .75 HP | 5.18 A | 120 V |
| 1 HP | 6.91 A | 120 V |
| 1.25 HP | 8.63 A | 120 V |
| 1.5 HP | 10.4 A | 120 V |
How many amps does a 1 HP pool pump draw?
12 Amps
Since it’s an aboveground pool pump it’s an uprated model and draws in the vicinity of 10 to 12 Amps at 120 volts. It might draw less depending on your plumbing.
How many amps does a 1 HP motor draw at 120 volts?
How many amps does a 20hp motor draw?
AC Motor Full Load Amperes
| HP | 200 Volts | 208 Volts |
|---|---|---|
| 20 | 62.1 | 59.4 |

How many amps does a 1 hp submersible pump draw?
3.2-amper
A 1 HP submersible pump engine will draw a 3.2-amper current if it is a single-phase motor at 230 volts of voltage. If it is a three-phase motor at 440 volts, it will draw a maximum 1.7-amper current.
How much current does a motor draw?
Full load amps in 120 and 240 volts electrical DC motors.
| Motor Rating (hp) | Current (amps) | |
|---|---|---|
| 120 V | 240 V | |
| 2 | 17 | 8.5 |
| 3 | 25 | 12.2 |
| 5 | 40 | 20 |
How many amps does a 1 hp motor take?
Look at the table the 1 hp motor takes will be 1.3 A at 440 Volts three-phase at the same time while using single-phase it takes only 3.8 Amps. Also 5 HP three-phase motor takes 6.4 Amps. In practically the current rating may change and which is based in the manufactured standard as well as the what grade copper they are using to winding the motor.
How many amps does a 230 volt motor have?
As a “rules of thumb” amps horsepower rating can be estimated to. 115 volts motor – single-phase : 14 amps/hp. 230 volts motor – single-phase : 7 amps/hp. 230 volts motor – 3-phase : 2.5 amps/hp.
How is current in amps equal to horsepower?
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.
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.
