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 circu- lar 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		Surge
	(Running) Watts	(Starting) Watts
Window AC,	1200		1800
10,000 BTU
Refrigerator	700		2200
1/3 HP Well Pump	1000		2000
27 in. Television	500		0
Light (75 Watts)	75		0
	3475 Total	2200 Highest
	Running Watts	Surge Watts
Total Continuous (Running) Watts			3475
Plus Highest Additional Surge Watts			+ 2200
Equals Total Generator Output Required			5675

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.

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.
