Generator Selection Guide
To determine the right generator for you, use the chart below to give some guidance. As a rule of thumb, Amperage x Voltage = Wattage. If you have 10 Amps and 120 Volts then that would equate to 1200 Watts.
To make your calculations, print your selector guide here. 
Use the following formula to convert to watts if necessary:
Amps x Volts = Watts (Single Phase - 90% you'll need this calc.)
Amps x Volts x 1.73 = Watts (Three Phase)
Running Watts** = Horsepower x 932 (for many motors)
*** For motors, remember that initial start-up will take from 3X to 6X as much power.
