DON'T OVERLOAD 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. This

is the amount of power your generator must

produce to keep your items running. See the table

on 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.

To prolong the life of your generator and attached

devices, it is important to take care when adding

electrical loads to your generator. There should be

nothing connected to the generator outlets before

starting it's 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 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 described above.
