4 don’t overload the generator, 5 wattage reference guide – Guardian Technologies 004583-0 User Manual
Page 11

Proper grounding of the generator will help prevent electrical 
shock in the event of a ground fault condition in the generator or in 
connected electrical devices. Proper grounding also helps dissipate 
static electricity, which often builds up in ungrounded devices.
2.3.2 CONNECTING ELECTRICAL LOADS
DO NOT connect 240 Volt loads to 120 Volt receptacles. DO NOT 
connect 3-phase loads to the generator. DO NOT connect 50 Hz loads 
to the generator.
Let engine stabilize and warm up for a few minutes after starting.
Plug in and turn on the desired 120 or 240 Volt AC, single phase, 
60 Hz electrical loads.
Add up the rated watts (or amps) of all loads to be connected
at one time. This total should not be greater than (a) the rated 
wattage/amperage capacity of the generator or (b) circuit breaker 
rating of the receptacle supplying the power. See "Don't Overload 
the Generator" below.
2.4 DON’T OVERLOAD THE GENERATOR
Overloading a generator in excess of its rated wattage capacity can 
result in damage to the generator and to connected electrical devices. 
Observe the following to prevent overloading the unit:
Add up the total wattage of all electrical devices to be connected
at one time. This total should NOT be greater than the generator's 
wattage capacity.
The rated wattage of lights can be taken from light bulbs. The rated
wattage of tools, appliances and motors can usually be found on a 
data plate or decal affixed to the device.
If the appliance, tool or motor does not give wattage, multiply volts
times ampere rating to determine watts (volts x amps = watts).
Some electric motors, such as induction types, require about three
times more watts of power for starting than for running. This surge 
of power lasts only a few seconds when starting such motors. 
Make sure to allow for high starting wattage when selecting 
electrical devices to connect to the generator:
1. Figure the watts needed to start the largest motor.
2. Add to that figure the running watts of all other connected 
loads.
The Wattage Reference Guide is provided to assist in determining 
how many items the generator can operate at one time.
NOTE:
All figures are approximate. See data plate on appliance for 
wattage requirements.
