Supposeyou plan to install a 5 kW air conditioner with a voltage of 220 V (single-phase AC) and a PF of 0.9. Plug these values into the formula: A m p s ( A) = 1000 × 5 k W 220 V × 0. 9 = 23. 81 A. Hence, you need wires and a circuit breaker capable of handling at least 23.81 amps to safely operate your new air conditioner. Moreinformation from the unit converter. How many kW in 1 hp? The answer is 0.746. We assume you are converting between kilowatt and horsepower [electric].You can view more details on each measurement unit: kW or hp The SI derived unit for power is the watt. 1 watt is equal to 0.001 kW, or 0.0013404825737265 hp. Note that rounding errors may occur, Foreasier explanation, let us review the example below: We have a circuit with 25kW three-phase power generator, 80% efficiency (0.8 PF) at 240volts. The amps will be: amps = CableSize Calculation of 125 Kw LT Motor. Load Current = P / (1.732 x V x Pf x Eff) —> (P = √3 x Vx I CosΦ = for three phase circuits) This is the full load current cable needs to cater in Ideal condition. But in practical situation, there are 35 kW to Amps Conversion. From our formulas follows that in order to get 3.5 kilowatts in amps we must know the voltage. Assumed the PF is 0.5, and supposed the voltage is Awound rotor motor, 7.5 HP, 230 volts, 3-phase takes a line current of 18.4 amperes, when operating at rated output at an efficiency of 88%. Calculate the indications on wattmeters when these are inserted to measure power by the two wattmeter method. A. 4.035 kW, 2.325 kW. B. 4.232 kW, 2.126 kW. C. 3.902 kW, 2.456 kW. D. 3.855 kW, AtGeneral Power, our 50Hz diesel generators incorporate advanced alternator technology, ensuring consistent power output and exceptional performance. Durability: Our generators are built to withstand challenging environments and heavy usage. With robust construction and durable components, they are engineered for longevity and minimal singlephase motors, and engineers should, whenever possible, determine the actual full load current load current from the motor rating plate.

Rta: // The solution is as simple as dividing 22kW / 0.81, as follows: 22 / 0.81 = 27.16.
