How many amps is 3 horsepower?

Common Horsepower to Amps Conversions

Horsepower Amps Efficiency
3 HP 20.7 A 90%
3.5 HP 24.2 A 90%
4 HP 27.6 A 90%
4.5 HP 31.1 A 90%

#### 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.

What is the full load current of a 1 hp motor?

Full Load Current: Three Phase AC Motors

Motor Horsepower Motor Ampere
1 230V 460 V 4.2 2.1
1-1/2 230V 460V 6.0 3.0
2 230V 460V 6.8 3.4
3 230V 460V 9.6 4.8

How many amps does a 1 hp pump draw?

A 240 volt, 1 horsepower well pump draws 10 amps of current.

## How many amps does a pump draw?

Divide the wattage by the voltage to find the current. For example, if the pump wattage is 2,200 watts, and the voltage is 110 volts, the current is 2,200 /110 = 20 Amps. This is the value of the amps drawn by the well pump.

What is the formula to convert HP to amps?

Knowing that we can write hp to amps formula for direct current (DC) as: I = P * 746 / (V * η) .

What size breaker do I need for a 40 hp motor?

25 230 V 460 V 100 50
30 230 V 460 V 125 70
40 230 V 460 V 175 100

### How to calculate the 3 phase amps of a motor?

Mathematical equation: Three phase Amps = [HP * 746] / [E * %age Efficiency * PF * 1.73] Example: Determine the current flowing through a three-phase, 2 HP, 400-volt motor having an efficiency rating of 93% and a power factor of 0.9. Solution: Current = [2 * 746] / [400 * 0.93 * 0.9 * 1.732] = 2.57 Amps

How to calculate dc amps using HP to amps?

DC Amps = [HP * 746] / [E * %age Efficiency] Example: Find the current passing through 24 volt, 1/2 HP motor having an efficiency of 95%. Solution: Current = [0.5 * 746] / [24 volt * 0.95] = 16.35 Amps Single phase AC Calculations

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.

#### What is the formula for three phase AC?

Three phase AC. The three-phase ac amps involve HP * 746 in the numerator and 1.73 times PF * Efficiency times voltages in the denominator. The formula is identical to the previous case with the difference of factor 1.73 instead of 2 in the denominator. Three phase Amps = [HP * 746] / [E * %age Efficiency * PF * 1.73]
