GEN2000 Portable Gasoline Generator

USING THE GENERATOR
After the engine has been running for several minutes, electrical devices may be connected to this generator.
AC Usage
Electrical devices running on AC current may be connected according to their wattage requirements.
Rated (Running) Wattage
1400
Surge Wattage
2000
The rated (running) wattage corresponds to the maximum wattage a generator can output on a continuous basis.
The surge wattage corresponds to the maximum amount of power a generator can output for a short time. Many electrical devices, such as a
refrigerator, require short bursts of extra power for starting and stopping fan motors, etc., in addition to their listed rated wattage. Motorized devices
typically require more than their rated wattage for startup. The surge wattage ability of a generator allows for this extra power requirement.
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.
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) by the Amperage drawn.
Watts = Volts x Amperes
Or, the wattage required by a device can be estimated by using the following chart. The chart provides only estimates and it is better to know the
exact wattage of each electrical device to be powered by this generator.
Connect only electrical devices that are in good
working order. Faulty devices or power cords
present the risk of electrical shock. Immediately
turn off and disconnect any device that
commences to operate abnormally, sluggish or
abruptly stops. Determine if the problem was the
device or the rated load capacity of this generator
has been exceeded.
NOTE: Plug appliances into the correct outlet. Connect
standard 120 Volt, single phase, 60 Hz loads to the 120
Volt outlet. Connect 12 Volt, DC loads to the 12 Volt
outlet.
