### How do you calculate amps from HP?

HP to Amps formula is used to calculate current from horsepower in single and three phase ac circuits as well as in DC circuits. The basic formulas for the calculations are: Formula: 3 phase Amps = [HP * 746] / [E * % Efficiency * PF * 1.73]

**How many amps per hp?**

1 horsepower = 745.699872 Watts (Google horsepower to obtain this number) The formula is P=VI, or Power = Voltage x current. This becomes P / V = A, or Power divided by voltage equals current. At 120 volts, 745.699872 Watts / 120 volts equals 6.214 amps. At 240 volts, 745.699872 Watts / 240 volts = 3.107 amps.

#### How to calculate 3 phase motor power consumption?

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). Convert watts to kilowatts by dividing the number of watts by 1,000.

#### How do you calculate full load current?

Full Load current calculation Single phase Motor: P = V X I X Cos pi. V= Voltage +/- 10 % in Volts. I= Full load current in Amps. Cos pi = power factor. KW = output power in Watts……. All are given at the motor’s name plate details. I = / V X cos pi Amps.
