CAPACITY
Make sure the generator can supply enough rated
(running) 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 rated (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 the 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:
Total Rated (Running Watts) = 3075 5800
Highest Additional Surge Watts = 1800
Total Generator Output Required = 4875 6200
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 the 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 earlier 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.
WARNING:
Do not overload generator's capacity. Exceeding
generator's wattage/amperage capacity can damage
generator and/or electrical devices connected to it.
