Figure 10- Estimated wattage requirements of common electrical devices.
Once you have found the rated wattage requirement of each electrical device, add these
numbers to find the total rated wattage you wish to draw from the generator. If this number
exceeds the rated wattage of the generator, DO NOT connect all these device, Select a
combination of electrical devices, which has 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
