## How much electricity does a 30 hp motor use? ## What wire do I use for 40 amps?

For a maximum of 40 amps, you'll need a wire gauge of 8.

## How much electricity does a 25hp motor use?

25 horsepower is about 18.6 KW, so that'd be \$1.49 an hour. Your mileage may vary.May 17, 2007

## How do I know how many amps my 3 phase motor is?

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.Jan 9, 2018

## How many amps does a 1.5 HP 220v motor draw?

The 1.5 HP Baldor motor that turns at 1725 will draw 18 amps according to its name plate.Jan 5, 2011  ### What is the difference between amps and horsepower?

Amps measure electrical current. Horsepower is the amount of energy a motor creates when in use.Apr 24, 2017

### How do you convert amps to horsepower?

• 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).

### What is the formula for amps?

• DC watts to amps calculation formula. The current I in amps (A) is equal to the power P in watts (W), divided by the voltage V in volts (V): I(A) = P(W) / V(V) So amps are equal to watts divided by volts. amp = watt / volt.

### What is full load amperage?

• Rated full-load amperage — As the torque load on a motor increases, the amperage required to power the motor also increases. When the full-load torque and horsepower is reached, the corresponding amperage is known as the full-load amperage (FLA).

### How do you calculate horsepower?

• 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.
