EXAMPLE 3:
ADDITIONAL STARTING WATTS 1500 Watts
RUNNING WATTS 1150 Watts
TOTAL 2650 Watts
Generator must have a maximum capacity of at least 2650 watts.
STARTING WATTAGE REQUIREMENTS
1. Some appliances and tools will list on the motor nameplate the starting and
running voltage and amperage requirements. Use the following formula to
con vert voltage and am per age to watt age:
Volts X Amp = Watts
Example: 120 volts x 10 amps = 1200 watts
2. To determine the approximate starting wattage re quirement for most appli-
ances and tools with inductive type motors, multiply the wattage that was
calculated by 2 to 4 times to assure adequate generator capacity. If the name-
plate information is not avail able 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.
The wattage ratings shown are averages. Wattage requirements may vary
with different brands of appliances.
