How many amps does a 2.5 hp motor draw?
Common Horsepower to Amps Conversions
| Horsepower | Amps | Voltage |
|---|---|---|
| 2 HP | 13.8 A | 120 V |
| 2.5 HP | 17.3 A | 120 V |
| 3 HP | 20.7 A | 120 V |
| 3.5 HP | 24.2 A | 120 V |
How do you convert HP to amps?
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.
What size breaker do I need for a 2 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 |
| 3 | 16.8 | 8.4 |
| 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.
What size breaker do I need for a 40 hp motor?

How many amps does a 1 HP pool pump draw?
1 HP is 746 watts x 1.5 HP = 1,119 watts. 1,119watts ÷ 120volts= 9.325 amps.
What size wire do I need for a 30 hp motor?
Electrical motor wiring data – NEMA amps, starter size, HMCP size for motors ranging 1/2 to 500 hp
| Motor HP | NEMA amps | Phase Wires (AWG) |
|---|---|---|
| 25 | 34 | 6 |
| 30 | 40 | 6 |
| 40 | 52 | 4 |

What size breaker do I need for a 1.5 hp motor?
Okay, a 1.5 HP motor at 115 volts the Full Load Current (FLC) is 20 amps, (table 430.148 NEC) to figure out short circuit and ground fault protection you take 250% x FLC, so 250% x 20 (FLC) = 50 amps, this is your circuit breaker size.
What size breaker do I need for a 20-amp motor?
Use 12-gauge wire for a 20-amp circuit, 10-gauge for 30 amps, 8-gauge for 40 amps, and 6-gauge for 50 amps.
