The total running wattage requirement of the electrical devices connected to a generator should not exceed the rated wattage of the generator itself.
To calculate the total wattage requirement of the electrical devices to be connected, look up the rated (running) wattage of each device and add
these numbers together to find the total wattage that all of the devices together will draw from the generator. If the total wattage of the selected
devices exceeds the rated wattage of the generator, DO NOT connect all of the devices. Select a combination of the electrical devices that will have
a total wattage less than or equal to the rated wattage for the generator, i.e., no more than 3000 for this ACDelco Model AC-G0002 3500 Surge
Watts / 3000 Running Watts Portable Generator.
This generator can run at its surge wattage capacity for only a short time. Connect electrical devices requiring a rated (running) wattage
equal to or less than the rated wattage of this generator. Never connect devices requiring a rated wattage equal to the surge wattage of a
generator.
A device's rated (running) wattage should be listed somewhere on the device itself and/or in its manual. If the wattage specification for a device is not
available, the wattage can be calculated by multiplying the Voltage requirement (120 or 240) by the Amperage drawn.
Watts = Volts x Amperes
Or, the wattage required by a device can be estimated by using the following chart (see Figure 7). The chart provides only estimates and it is better
to know the exact wattage of each electrical device to be powered by this generator.
