Using The Generator - DUROMAX XP4400 Owner's Manual

USING THE GENERATOR

Once you have allowed the engine to run for several minutes, you may connect electrical
devices to the generator.
AC Usage
You may connect electrical devices running on AC current according to their wattage requirements.
The chart in figure 9 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 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.

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:
