How much electricity does 1 hp motor consume per hour?

If I have a 1 HP motor that runs 1 hour, it will consume 750 watts, if it starts one time.

How do you calculate the power of a 3 phase motor?

Calculate three-phase motor power consumption by multiplying amps by volts by the square root of three (W = AV(sqrt 3). For example, if the motor is drawing 30 amps at 250 volts, you have 30 x 250 x sqrt 3 (about 1.73) = 12,975 watts).

How much watts does a fridge use?

The average home refrigerator uses 350-780 watts. Refrigerator power usage depends on different factors, such as what kind of fridge you own, its size and age, the kitchen’s ambient temperature, the type of refrigerator, and where you place it.

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 many amps is 3 horsepower?

Common Horsepower to Amps Conversions

How do you calculate the full load of a 3 phase motor?

For three-phase, full load current for the resistive load is equal to the three-phase power divided by 1.732 times of voltage. Here power factor will be unity for resistive loads. Full load current I, I =P.
