# Question: How Many Horsepower Is A 15 Amp Motor?

## What size breaker do I need for a 7.5 hp motor?

Re: Wire and breaker size for 7.5 hp motor You need 50 amp rated wire with a 50-100 amp breaker..

## What horsepower is 5252?

We need to get to horsepower, which is 550 foot-pounds per second, using torque (pound-feet) and engine speed (RPM). If we divide the 550 foot-pounds by the 0.10472 radians per second (engine speed), we get 550/0.10472, which equals 5,252.

## What is the formula to convert kVA to HP?

In summary, (kVA x PF x 1,000) / 746 = horsepower.

## How do you convert HP to amps?

The wattage for the blender example would be 5 A * 115 V = 575 W. Divide the wattage by the conversion factor 746 W per HP to convert watts to horsepower. The equation would be as follows: (W) / (746 W per HP) = HP. In our example, (575 W) / (746 W per HP) = 0.75 or 3/4 HP.

## How many amps does a 7.5 hp motor draw?

## How many watts is a 1.5 hp motor?

1125 watts1hp equal to 750 watts so 1.5. hp equal to 1125 watts .

## What is a horsepower equal to?

The electrical equivalent of one horsepower is 746 watts in the International System of Units (SI), and the heat equivalent is 2,545 BTU (British Thermal Units) per hour. Another unit of power is the metric horsepower, which equals 4,500 kilogram-metres per minute (32,549 foot-pounds per minute), or 0.9863 horsepower.

## What does a 15 amp motor mean?

A 15 amp 120vac circuit is rated for a continuous load of 12.5 amps. For a 15 amp load you need a 20 amp branch circuit.

## How many amps is a 1 hp motor?

## How many amps does a 1.5 hp motor?

1 Horsepower is 745.7 watts, so a 1.5 HP motor would require a maximum of 1118.55 watts. 1118.55 W / 220V equals 5.084 amps, so in theory your motor will need just over 5 amps of current.

## What happens if the amps are too high?

A higher voltage than a device is designed for will most likely blow up some components, but amperage is derived from how much current is actually drawn, based on the device’s resistance, so having “too much” is not a problem and will do no harm. It takes 200 cells at 1.5 volts each to produce 300 volts.

## How many amps does a 1 HP pool pump draw?

10 to 12 ampsSince it’s an aboveground pool pump it’s an uprated model and probably draws in the neighborhood of 10 to 12 amps at 120 volts. Depending on your plumbing it may draw less.

## How much power does a 2 hp motor use?

## What should motor overloads be set at?

The required overload protection setting for motors is 125% of their full-load current according to the NEC, but make sure you read the overload relay instructions as well. Some manufacturers have the 125% setting built in, which means you must set the overload protection at the motor’s nameplate current.

## How many rpm is 1 HP?

Let’s look a two 1 HP motors. The 1800 RPM, 1HP motor produces 3 ft. lbs of torque at 1800 RPM. The 3600 RPM, 1HP motor produces 1.5 ft.

## What is the difference between amps and horsepower?

Amps measure electrical current. Horsepower is the amount of energy a motor creates when in use.

## How do you calculate motor horsepower?

Using the formula (V * I * Eff)/746=HP, determine your electric motor’s horsepower. Multiply the voltage, the current, and the efficiency, then divide the result by 746. For example, the horsepower of a 230v motor pulling 4 amps and having 82% efficiency would equal 1 horsepower.

## How many amps does a 1.5 HP pump draw?

A 1.5 HP motor at full load will produce 1.5 HP, which is just over 1100 watts. if we assume 90% efficiency, it will consume just over 1200 watts. On a 110 volt supply this equates to about 11 amps. On a 230 volt supply this is a little over 5 amps.
