Typical Equipment Power Requirement Information
You can calculate your requirement more accurately by reading the equipment labels for the stated Voltage, Current and Wattage ratings. Note: Voltage times Current = Watts (V x I = W). Total the wattages of all equipment that will be run at the same time.

Also note that electric motor starting may require up to three times the nameplace running power. After initial start, less power is required.
To determine motor wattage: Watts=horsepower times 932 (W=HP x 932).
