STARTING WATTAGE REQUIREMENTS
1. Some appliances and tools will list on the motor
name plate the starting and running voltage and
amperage requirements. Use the following formula to
convert voltage and amperage to wattage:
Volts X Amp = Watts
120 volts x 10 amps = 1200 watts
To select the right generator for your needs, total the wattage
of the items to be run at the same time.

The wattage ratings shown are averages. Wattage requirements may vary
with different brands of appliances.

2. To determine the approximate starting wattage
requirement for most appliances and tools with
inductive type motors, multiply the wattage that
was calculated by 2 to 4 times to assure adequate
generator capacity. If the nameplate information is
not available use the values on the following chart
as a guide.
3. Remember that the starting and running wattage
for resistive loads are the same. (Example: a 100
watt light bulb requires only 100 watts to start.)
Most resistive loads will be listed in wattage.
