Use the actual bulb wattage and not the incandescent wattage. *Energy efficient bulbs are often compared to their incandescent counterparts. Visit our Portable Generator Sizing Guide for help choosing the right generator to fit your needs. Only running watts apply to appliances without motors.
Actual power requirements may vary by manufacturer, motor size and type of motor used. The following table lists typical power requirements for starting and running some common appliances. Note the large, 120/240-Volt 50-Amp Outlet at the bottom right of the control panel. Up to 50 Amps of Power at 240-Volts for supplying a 50-Amp manual transfer switch through a single generator cord. The DuroMax XP15000EH Dual Fuel Generator with 15,000 Starting Watts and 12000 Running Watts. Propane is another option for peak demand, but provides a 1000 watts less power. They may want to reserve their gasoline supply for peak power usage and use natural gas when power demand is low. DuroMax Tri-Fuel XP13000HXT Fuel Typeįor the DuroMax Tri-fuel, it’s important for the homeowner to know they can expect 2000 more running watts while running on gasoline than on natural gas. For this reason, generator manufacturers will provide different capacity ratings for each fuel.Įxample: The DuroMax 13000-Watt Tri Fuel Generator has three ratings for running watts, and three ratings for starting watts. Gasoline contains more energy than propane, which contains more energy than natural gas. Gasoline only models, Dual Fuel models, and Tri Fuel models offer different fuel options. A generator must provide this surge of power for for several seconds without overloading. At startup, motors require two to six times more power than their continuous power requirement. Starting watts is a boost of power available for a few seconds while starting a motors. Runnign watts refers to the power the generator is able to supply continuously without overloading. Generators come with two power capacity ratings the maximum or starting watts and the continuous capacity or running watts. Generator Capacity is rated in watts or kilowatts because it is the power that matters, not the voltage.
At 240 volts, a 600-watt appliances requires 2.5 amperes of current, but at 120 volts it requires twice the current-5.0 amperes. On some appliance tags, this is expressed as Volt-Amps or VA others express their power requirements in watts or kilowatts.Īppliances require a certain amount of power regardless of the voltage use.
A device that runs on 120 volts and draws 5 amperes uses 600 watts (120V x 5A) of power. Calculate Watts by multiplying voltage by amperes. Power is measured in Watts (W) or in Kilowatts(kW). Different fuels contain different amounts of energy which affects how much power the generator can produce while using each fuel type. This Champion Tri-Fuel Generator runs on three different fuels-Gasoline, Propane, and Natural Gas.
