How much power does a 7.5 hp motor consume?
Let us assume that motor is operating at full load so it will consume 7.5 hp or 5.59 or 5.6 kW approx. Let us assume motor has efficiency of 90 %, motor at full load gives around 90 % efficiency, so the power input to motor is 5.6/0.9=6.22 kW. Energy consumption in 2 hrs = 6.22x2=12.44 KWh or 12.44 unit.

How do I convert HP to amps?
Converting horsepower to amps can be done in a few simple steps, or using this simple formula.Amps = (Horsepower × 746) ÷ Efficiency ÷ Volts.Watts = Horsepower × 746.Watts = Watts ηAmps = Watts ÷ Volts.Amps = HP × 746 V × η × PF.
How to calculate wattage of a motor?
Multiply amps by volts to obtain the motor's wattage, or watts (A * V = W). Wattage is the same type of unit as horsepower, a measure of power, so it can readily be converted (like gallons to quarts). The wattage for the blender example would be 5 A * 115 V = 575 W.
How many watts does a 240 x 10 amp pull?
On start it will pull 35ish amps, but only for . 5-1 second. 240 x 10= 2400 Watts but you will need a surge capacity of around 8000 watts as the start amps are much higher.
How to find horsepower in a car?
To calculate the horsepower of a car, start by finding the engine's torque value and engine speed in the owner's manual. Multiply the torque by the engine speed, and then divide that number by 5252. The answer is the horsepower for the car's engine.

Use a 12 wire and a 20A breaker. 15A ends are allowed on 20A circuits.
What is an ampere?
An ampere is a unit of measure of the rate of electron flow or current in an electrical conductor. One ampere of current represents one coulomb of electrical charge (6.24 x 1018 charge carriers) moving past a specific point in one second. The ampere is named after Andre Marie Ampere, French physicist (1775-1836).
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.
Does increasing horsepower increase ampere value?
Look at that, while increasing the horsepower rating the ampere value and motor size also will be increased.
How many amps does a 5 HP motor need?
P.S Asking how many amps a 5 HP motor needs isn't a question that can be answered. A high quality high power factor/high efficiency 5HP motor may be as low as 18 amperes, or as high as 28 if it's a low efficiency/low power factor motor. That's why you need to obtain the motor full load current from the motor nameplate....Regards, Rod.
How far does a breaker box go from a motor?
From the breaker box to the motor only about 20-22 ft. When the supply house consulted some tables and the info from the motor, they said I could go with 30A but said it was only about 2A from potentially popping the breaker. I'm no electrician and went with their recommendation. I think it was startup current draw they said might pop the breaker IIRC, not the normal operating current.
What breaker is used for a 5 HP Clear Vue?
My 5hp Clear Vue is on 10 guage and 30 amp breaker. Never a problem. In fact, that was what Leeson recommended for the motor, IIRC. My run is only about 14' max from the breaker. Jim.
What wire do I use for a contactor switch?
40A and 8 ga wire was what the folks at the elec supply house said to use for the contactor switch & breaker when I wired up my 5HP ClearVue cyclone.
What is the purpose of a 40 amp breaker?
Remember that the breaker is to protect the wiring so if you're going to use a 40 amp breaker, make sure your wire in the circuit will handle 40 amps.
Can a 30A circuit be used for a 5HP motor?
A 30a circuit is fine for a 5HP motor. Unless you've got an extraordinarily long wire run 10ga wiring is also fine. The start surge on a 22 FLA motor won't trip a properly functioning 30a breaker unless the motor is locked up, otherwise defective, or is trying to start under a high static load. Modern compressors have unloader valves that reduce the startup loads so that it should be no harder starting than an equivalent motor spinning up a heavy blower wheel in a DC/cyclone.
Can I run a 5 HP Woodmaster sander on 30 amp?
I run my 5hp Woodmaster sander on 30amp /10ga without any problems but I would run a 5hp compressor on a 40amp/8ga due to the higher loads, particularly on startup.
How to calculate HP to amps?
Rearrange the formula of hp to amps for the three-phase line-to-line system P = I * √3 * V * PF* η / 746;
How many watts is 1 HP?
Estimate the power in watts (the nominator of the expression), 1 hp * 746 = 746 W;
How to convert power to watts?
A rule of thumb states that you should multiply the power in hp by 746 to get the power in watts. Here we are assuming you're using electrical horsepower (for mechanical horsepower, the factor is circa 745.7 ).
What does amps represent?
Similarly, the amps represent the amperage, which refers to the electric current measured in amperes. Whenever you face the challenge of converting horsepowers to amps, you are about to estimate the output current from a device with a well-defined power. Analogically, if you try to convert amps to hp, you should evaluate the power knowing ...
What does HP stand for in electrical?
Hp stands for the horsepower - the unit of, well, power. Similarly, the amps represent the amperage, which refers to the electric current measured in amperes.
What is the output current of Ohm's law?
According to Ohm's law, the output current I is a ratio of the power P and the output voltage V. However, it changes a bit in real-life applications, as any power engine works with a certain efficiency η. Knowing that we can write hp to amps formula for direct current (DC) as:
Can you use amp to HP calculator?
You can also use our tool as an amp to hp calculator. Take a look at the next example:
How much horsepower should a motor have?
For a 1 horsepower (hp) motor the load should typically be in the range 1/2 to 1 hp with maximum efficiency at 3/4 hp. A motor with a service factor can occasional be overloaded. Overloading will over time reduce motor efficiency.
What is motor efficiency?
A motor of a given rated horsepower is expected to deliver that quantity of mechanical power at the motor shaft. Be aware that the motor efficiency is not calculated in to the values for kW and amps below. Motor efficiency must be considered to avoid undersized power supply.

This means that in 10.5 volts and at around 80F, the battery will draw 20 amps in a certain number of minutes.
How many amps does a trolling motor need?
Yes, both weather and water will impact the time your trolling motor can work at one battery charge. If your boat can move at a standard speed using only 10 amps in good weather, if there are strong winds and a slight storm, you may need 20 amps or more.
What is cranking amp?
Cranking amps is the number of amps your battery can give in 32F for 30 seconds. There’s another type called cold cranking amps which represents the same measurement but at 0F. CAs work great for starter motors because in this case, you need a short yet powerful energy boost.
What does amp draw mean?
Amperage draw shows how much amp your battery draws at a speed you want to achieve. It may be difficult to find out the exact number, but the manufacturer should be able to help you with it.
What is amps hours?
Here, we have: Amps hours; Cranking amps. Amps hours is a measurement telling how many amps are delivered in a number of hours. Let’s take the easiest 100 amp hour battery. It will either use: 20 amps for 5 hours;
What is a trolling motor battery?
The battery in a trolling motor is used to store extra energy for use when necessary. Boat batteries are similar to the ones in cars, so let’s talk about those for a bit. A car battery is usually a “floating one”. This means there’s a battery case in which acid flows, covering lead plates.
How many hours does a 100 hour battery last?
Example: You have a 100-hour battery in a motor that gives 30 amps at a standard speed. Using the formula, you’ll get 3.3 hours. This is for one full charge of the battery.
