# How do you calculate amps from kW?

## How do you calculate amps from kW?

To convert amps to kilowatts the power formula can be used, which states that I = P ÷ E, given that P is the power in watts, I is current in amps, and E is voltage in volts. Thus, the power P in kilowatts is equal to the current I in amps multiplied by the voltage V in volts, divided by 1,000.

What size wire do I need for a hp motor?

### How to calculate kilowatts to amps in a calculator?

Select current type, enter power in kilowatts, voltage in volts, power factor for AC circuit and press the Calculate button (DC = Direct Current, AC = Alternating Current): Amps to kW calculator ►. The current I in amps (A) is equal to 1000 times the power P in kilowatts (kW), divided by the voltage V in volts (V):

How to find the power P in kilowatts?

The power P in kilowatts (kW) is equal to the current I in amps (A), times the voltage V in volts (V) divided by 1000: P (kW) = I (A) × V (V) / 1000 P (kW) = PF × I (A) × V (V) / 1000 P (kW) = √3 × PF × I (A) × V L-L (V) / 1000 P (kW) = 3 × PF × I (A) × V L-N (V) / 1000

How to calculate the size of a wire?

Wire Size Calculator This calculator requires the use of Javascript enabled and capable browsers. The purpose of the calculator is to determine the size of the conductor wire in a circuit of a given distance with a given amperage load. Select the type conductor wire material, the circuit voltage and the phase of the circuit.

#### How to calculate the ampacity of a wire?

To calculate wire ampacity for a circuit, use the Wire Ampacity Calculator or the Advanced Wire Ampacity Calculator. For long conductor runs where voltage drop may be an issue, use the Voltage Drop Calculator to determine proper conductor sizing and maximum circuit length.
