Power is power and you draw 3730 watts with either scenario. For more reliable motor protection, use the actual motor current as listed on the motor nameplate. Solution: I = 100*1000/(3. Initially, we explored the idea of three-phase power systems by connecting three voltage sources together in what is commonly known as the "Y" (or "star") configuration. 2 amps x 175% (T430-152) = 23. 33 times 3, or 250 amps. 3*1000) = 30. 3 Phase Diesel Generators are popular for portable trade, construction and agricultural applications - operating machinery such as larger water pumps, compressors, wool presses. How many amps for 200 KVA generator per phase leg? To answer this question correctly, the voltage of the generator. Calculator-1 Input the system line-line voltage, line current, and power factor angle (degrees) into Calculator-1 to compute three-phase reactive power, real power, and total power as well as the power factor. There is a limit to the load that a single phase can handle and typically that number is set to 7. 35 A 120 V 1. Rated Voltage: 415 V.
