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 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 connect devices requiring a rated wattage equal to the surge wattage of
the generator.
NOTE: The above wattage figures are estimates. Try to check the wattage listed on your electrical
device before consulting this chart.
Once you have determined what electrical devices you will be powering with the generator, connect
these devices according to the following procedure:
1. Plug in each electrical device with the device turned off.
a. NOTE: Be sure to attach appliances to the correct receptacle (outlet). Connect
standard 120 Volt, single phase, 60 Hz loads only to the 120 Volt receptacle.
b. Connect 120/240 Volt, single phase, 60Hz loads with NEMA L14-30 plug only to the
120/240 Volt receptacle. See Figure 11 for a depiction of each of these receptacles.
2. Switch the circuit breaker to the "ON" position.
3. Turn on the connected electrical devices in the order of the amount of power they require
