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.

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.

300 200: 5 4: 220.8 For example, the full-load current of a 5 HP motor at 460V is 7.6 Amps. The breaker must be sized for 7.6 * 1.25 = 10 Amps. Therefore, it is good practice to size the breaker at 15 Amps. A heater is a device that protects a motor from thermal overloads due to excess current in the windings. According to the NEC, the
