It depends on what the voltage is: A Watt is a unit of power described as "1 ampere of current pushed by 1 volt of Electro-motive force", therefore 1W = 1A x 1V. 1 kW is a "kilowatt" or 1000 Watts. Using the above formula, and a little algebra, you can find the current required to deliver any amount of power depending on the applied voltage: Current = Power / Voltage; symbolically expressed as I = P / V examples:

* 9.5kW x (1000W/kW) / 120v = 79.2 amps

* 9.5kW x (1000W/kW) / 240v = 39.6 amps

* 9.5kW x (1000W/kW) / 480v = 19.8 amps (Notice how raising the voltage reduces the required current?)
