Available Generators
Electric equipment is generally divided into inductive and resistive loads. Inductive loads are primarily things with motors like furnaces blowers, saws, drills, refrigerators, pumps and air compressors. Electric motors can require 3 to 6 times their running current when starting. Air compressors and submersible pumps have very high starting currents. Resistive loads are things like coffee makers, lights, electric heaters and TV's. 1. Add the wattages of all resistive loads to be operated at the same time. Most appliances have labels or nameplates listing wattage. If amperage is listed multiply amps x voltage to find watts. 2. Determine the starting wattage of inductive loads. Remember, if the nameplate says your furnace fan draws 600 watts, 1800 watts (or more) is the starting wattage. 3. Add the totals from step 1 and step 2 to get total wattage. Add 20% to the total to allow for line drop or additional equipment. For example: You want to run a television, a few lights, a refrigerator and your furnace.
If running an air compressor or submersible pump a starting current of 4-6 times the running current should be used. |
