Wire Gauge) stranded copper wire. This grounding wire should be connected at the other end to a
copper, brass, or steel-grounding rod that is driven into the earth. Wire and grounding rod are not
included in generator contents.
Grounding codes can vary by location. Contact a local electrician for area codes.
USING THE GENERATOR
WARNING:
When this generator is used to supply a building wiring system:
Generator must be installed by a qualified electrician and connected to a transfer switch
as a separately derived system in accordance with the National Electrical Code, NFPA 70.
The generator shall be connected to a transfer switch that switches all conductors other than the
equipment grounding conductor. The frame of the generator shall be connected to an approved
grounding electrode.
For power outages, permanently installed stationary generators are better suited for providing
backup power to the home. Even a properly connected portable generator can become overloaded.
This may result in overheating or stressing the generator components, possibly leading to a
generator failure.
Before connecting electrical devices, allow the generator to run for a few minutes to stabilize the
speed and voltage output.
CAUTION: Become familiar with the markings on the panel before connecting electrical devices.
Connect electrical devices running on AC current according to their wattage requirements. The
chart in figure 9 shows the running and starting wattage of your generator according to its model
number.
NOTE: Although the overall running wattage of the machine is 3250 Watts, it is not recommended
that you attempt to draw more than 2400 Watts (20 A) from any ONE of the 120 Volt duplex
receptacles. The duplex receptacles are rated 20amps.
The running wattage corresponds to the maximum wattage the generator can output on a
continuous basis.
The starting 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 running wattage listed by the device, to stop and start their motors. The
starting wattage ability of the generator covers this extra power requirement.
Model Number Running Wattage Starting Watt

Figure 9- generator wattage by model number.
The total running wattage requirement of the electrical devices connected to the generator should
not exceed the running 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 Amperes
