Its voltage is 220V, while the power factor is 0.8 with an efficiency of 90%. With these values in mind, we'll arrive at the following equation: I = (25 x 746) / (√3 x 220 x 0.8 x 0.9) The total pullout current is 67.98 amperes. 2. Get the exact ampere rating relative to the type of circuit breaker you're using.

RLA - "Running Load Amps" - current drawn during normal operation of electric motor. FLA - "Full Load Amps" - amount of current drawn when full-load torque and horsepower is reached for the motor.FLA is usually determined in laboratory tests.Note! - in the calculator above FLA is RLA + 25%. 1 hp = 0.745 kW; Related Mobile Apps from The Engineering ToolBox

Oct 25,  · One horsepower (electric motor) is 746 watts, so ten horsepower is 7460 watts. Divide that by a power factor (assumed) of 0.8 and you get 9325 volt-amps. Divide that by a voltage (again, assumed) of 240 and you get 39 amperes. For calculation purposes the electrical code book states that a 10 horsepower motor at 240 volts will draw 50 amps.

In these cases, the nameplate current ratings shall be used. Caution: The actual motor amps may be higher or lower than the average values listed above. For
