GENERATOR
Capacity
You must make sure your 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. See
Figure 6.
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.Total surge watts is estimated by adding
only the one item with the highest additional surge
watts to the total rated watts from step 2.
For Example:
Total Rated (Running) Watts = 1875
Highest Additional Surge Watts = 1600
Total Generator Output Required = 3475
Power Management
It is important to take care when adding electrical loads
to your generator.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 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 generator capacity.Take
special care to consider surge loads in generator capacity,
as described above.
