Appliance Wattage Chart
The wattage noted below for each appliance is approximate only; please refer to
the specific tool or appliance for exact wattage or purchase a watt meter.
You can also figure out the wattage of an appliance by multiplying the number of
amps stated on the appliance label by 120 (volts). Amps x Volts = Watts

Generator Sizing Example
Use the example in the chart below as a guide to help you determine which size
generator best fits your needs.
1. Make a list of each appliance you want to run and enter the running watts and
surge watts beside each appliance.
2. Total up the running watts of all the appliances. Add to this the highest
appliance surge wattage number - the appliance makes no difference. Choose a
generator with a surge watt rating at or above the grand total from your
worksheet.
