seconds when starting such motors. Make sure to allow for high starting wattage
when selecting electrical devices to connect to the generator:
1. Figure the watts needed to start the largest motor.
2. Add to that figure the running watts of all other connected loads.
The Wattage Reference Guide is provided to assist in determining how many
items the generator can operate at one time.
NOTE: All figures are approximate. See data label on appliance for wattage
requirements.
Know Generator Limits
Overloading a generator can result in damage to the generator and connected
electrical devices. Observe the following to prevent overload:
• Add up the total wattage of all electrical devices to be connected at one time.
This total should NOT be greater than the generator's wattage capacity.
• The rated wattage of lights can be taken from light bulbs. The rated wattage of
tools, appliances, and motors can be found on a data label or decal affixed to the
devi
ce.
• If the appliance, tool, or motor does not give wattage, multiply volts times
ampere rating to determine watts (volts x amps = watts).
• Some electric motors, such as induction types, require about three times more
watts of power for starting than for running. This surge of power lasts only a few
