WATTAGE CALCULATIONS
STARTING WATTAGE REQUIREMENTS 2
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 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.
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.
To select the right generator for your needs, total the wattage
of the items to be run at the same time.
