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 RV Air Conditioner (11,000 BTU) TV (Tube Type) RV Refrigerator Radio Light (75 Watts) Coffee Maker Running Watts* 1010 300 180 200 300 600 2590 Total Running Watts Starting Watts* 1600 0 600 0 0 0 1600 Highest Starting Watts Total Running Watts Highest Starting Watts Total Starting Watts Needed 2590 + 1600 4190 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.
