USING THE GENERATOR
WARNING: When this generator is used on a building’s wiring system, the 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 machine’s 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.
AC Usage
Connect electrical devices running on AC current according to their wattage requirements. The chart
below shows the rated and surge wattage of the generator.
Model Rated Wattage Surge Wattage
PS50 1000W 1200W
The rated (running) wattage is the wattage the generator can produce on a continuous basis.
The surge wattage is the maximum amount of power the generator can produce for an extremely short
period of time (seconds). Many electrical devices such as refrigerators require short bursts of extra power
in addition to the rated wattage listed by the device to start their motors. The surge wattage ability of the
generator covers this extra power requirement.
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 plan 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 this wattage cannot be found,
calculate it by multiplying the Voltage requirement by the Amperage drawn:
Watts = Volts x Amperes
If these specifications are not available, estimate the wattages requirement of the device by using the
chart in next page.
When the rated wattage requirement of each electrical device has been determined, add these numbers to
find the total rated wattage needed. If this number exceeds the rated wattage of the generator, DO NOT
connect all these devices. Select a combination of electrical devices, which have a total rated wattage
lower than or equal to the rated wattage of the generator.
CAUTION:The 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 the generator. Never
