How do you 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 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 3/4 hp motor draw?

AMP DRAW BASED ON HORSEPOWER

HP 1 Phase Amps
115 volt 230 volt
1/2 9.8 4.9
3/4 13.8 6.9
1 16 8

What size breaker do I need for a 3 HP motor?

What size breaker do I need for a 3 HP motor? A 20 amp breaker is all you’d ever need for a 220v 3HP motor. It wouldn’t hurt anything to run 30amp circuits if you so choose, but it’s overkill.

How do you calculate amps in a 3 phase circuit?

Divide the power consumption in watts by the line voltage multiplied by the power factor to find the amperage. For three phase circuits the power factor is the square root of 3. If your calculator doesn’t have a square root function, use 1.73 as an approximation of the square root of 3.

How many amps does a 2 HP well pump draw?

When delivering 1/2hp to the pump, it draws 5.0 Amps. If that motor operates at its service factor of 0.8, it will draw 6.0 Amps. Most installations have motors near the maximum load.
