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.

Example:
	Running (Rated)		Additional Starting
	Running (Rated)		Additional Starting
Tool or Appliance	Watts		(Surge) Watts
Microwave Oven	1000		—

Refrigerator	700		2200

Furnace Fan	800		2350

Light (75 Watts)	75		—

	2575 Total		2350 Highest
	Running Watts		Starting Watts
Total Rated (Running) Watts		= 2575
Highest Additional Surge Watts		= 2350
Total Generator Output Required		= 4925

Power Management

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 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 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.
