WATTAGE CALCULATIONS
Never exceed the rated capacity of your generator. Serious damage to the
generator or appliance could result from an overload.
1. Starting and running wattage requirements should always be calculated when
matching a generators wattage capacity to the appliance or tool.
2. There are two types of electrical appliances that can be powered by your
generator:
A. Items such as radios, light bulbs, television sets, and microwaves have a
"resistive load". Starting wattage and running wattage are the same.
B. Items such as hand tools that use an electrical motor have an "inductive
load". Inductive load appliances and tools require approximately 2 to 3
times the listed wattage for starting
the equipment. This initial load only
lasts for a few seconds on start-up but is very important when figuring
your total wattage to be used.
C. Always start your largest electric motor first, and then plug in other
items, one at a time.
NOTE: On 120-volt loads the maximum starting wattage should NOT exceed
1250 watts.
IMPORTANT
DETERMINING WATTAGE REQUIREMENTS
Before operating this generator list all of the appliances and/or tools that are going
to operate at the same time. (Then determine the starting wattage requirements and
the running wattage requirements by following example and/or refer to household
wattage calculator.)
1. First total the running wattage of all appliances and/or tools that will be
operated at the same time.
Running W
atts Starting Watts
Example 1:
Lights = 100 Watts 0
Television = 300
Watts 0
TOTAL = 400 Watts 0
2. Next the starting wattages of any appliances and/or tools that will start and
stop during operation.
Running W
atts Starting Watts
Example 2:
Blender 400 W
atts 800 Watts
TOTAL = 400 Watts 800 Watts
3. The running wattage of examples 1 & 2 totals 800 watts. The starting wattage
of the blender is 800 watts which is 400 watts more than the running watts.
Take this difference of 400 starting watts from the blender and add to the total
running watts of 800.
Example 3: 400 Starting Watts
800 Running W

TOTAL =1200 Total Watts
Generator must have a maximum capacity of at least 1200 watts.
