ELECTRICAL GENERATOR CAPACITY Make sure the generator can supply enough continuous (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 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 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: Tool or Appliance Running Watts* Starting Watts* Refrigerator 600 780 Portable Fan Laptop 46 in. Flat Panel Television Light (75 Watts) 40 250 190 75 1155 Total Running Watts 120 0 0 0 780 Highest Starting Watts Total Running Watts Highest Starting Watts Total Starting Watts Needed 1155 + 780 1935 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. NOTICE: Do not overload the generator's capacity. Exceeding the generator's wattage/amperage capacity may damage the generator and/or electrical devices connected to it.
