USING THE GENERATOR
AC Usage
The total running wattage requirement of the electrical devices connected to the generator should
not exceed the rated wattage of the generator itself. To calculate the total wattage requirement of
the electrical devices you wish to connect, find the rated (or running) wattage of each device. This
number should be listed somewhere on the device or in its instruction manual.
If you cannot find this wattage, you may calculate it by multiplying the Voltage requirement by the
Amperage drawn: Watts = Volts x Amps. If these specifications are not available, you may estimate
the Watts required by your device by using the chart on the next page.
Once you have found the rated wattage requirement of each electrical device, add these numbers
to find the total rated wattage you wish to draw from the generator. If this number exceeds
the rated wattage of the generator, DO NOT connect all these devices. Select a combination of
electrical devices, which has a total rated wattage lower than or equal to the rated wattage of the
generator.

●
You may connect electrical devices running on AC current according to their wattage
requirements.
● The chart below shows the rated and surge wattage of your generator according to its model
number.
●
The rated wattage corresponds to the maximum wattage the generator can output on a
continuous basis.
● The surge wattage corresponds to the maximum amount of power the generator can output for
a short period of time. Many electrical devices such as refrigerators require short bursts of extra
power, in addition to the rated wattage listed by the device, to stop and start their motors. The
surge wattage ability of the generator covers this extra power requirement.
