GENERATOR CAPACITY
Make sure the generator can supply enough continuous (run-
ning) and surge (starting) watts for the items you will power
at the same time. Follow these simple steps.
1. Select the items you will power at the same time.
2. Total the continuous (running) watts of these items. This
is the amount of power the generator must produce to
keep the items running. See the wattage reference chart
at right.
3. Estimate how many surge (starting) watts you will need.
Surge wattage is the short burst of power needed to start
electric motor-driven tools or appliances such as a circular
saw or refrigerator. Because not all motors start at the
same time, total surge watts can be estimated by adding
only the item(s) with the highest additional surge watts to
the total rated watts from step 2.
Example:
Tool or Appliance
Continuous
Running) Watts
Surge
(Starting) Watts
Furnace Fan 800 2350
Refrigerator 700 2200
Well Pump 1000 1500
Light (75 Watts) x 4 300 300
2800 Total
Running Watts
2350 Highest
Surge Watts
Total Continuous (Running) Watts 2800
Plus Highest Additional Surge Watts + 2350
Equals Total Generator Output Required 5150
POWER MANAGEMENT
To prolong the life of the generator and attached devices,
it is important to take care when adding electrical loads to
the generator. There should be nothing connected to the
generator outlets before starting its engine. The correct and
safe way to manage generator power is to sequentially add
loads as follows:
1. With nothing connected to the generator, start the engine
as described later in this manual.
2. Plug in and turn on the first load, preferably the largest
load you have.
3. Permit the generator output to stabilize (engine runs
smoothly and attached device operates properly).
4. Plug in and turn on the next load.
5. Again, permit the generator to stabilize.
6. Repeat steps 4 and 5 for each additional load.
Never add more loads than the generator capacity. Take
special care to consider surge loads in generator capacity
as previously described.
CAUTION:
Do not overload the generator’s capacity. Exceeding the
generator’s wattage/amperage capacity can damage
the generator and/or electrical devices connected to it.
