Book Excerpt
GENERATOR BASICSOVERLOADS AND UNDERLOADS In many instances of generator problems, the trouble comes from improper use of application rather than a fault in the generator, itself. Extension cords are the primary cause of underloads. Using a cord with too small a wire gauge or too long a length will, because of resistance from the small size or long length, cause a voltage drop between the generator and the load. Full voltage, therefore, cannot reach the load, usually resulting in equipment burnout. Refer to the following chart for the correct extension-cord length for the load applied. Loads are listed for 120-volt output; the load can be doubled for 240 volts.
GROUNDING Always use the ground terminal and wing nut on the generator frame to connect the generator to a proper ground. The generator-to-ground connection should be made with a minimum #8 gauge solid-conductor wire. A metal underground water pipe in direct contact with the earth for at least 10 feet is the ideal ground. If this is not available, use at least an 8-foot length of 3/4-inch diameter pipe with a non-corrosive surface, or a 5/8-inch diameter steel or iron rod. The pipe or rod should be driven into the ground to a depth of eight feet or, if this is not possible, buried in a trench. All electrical tools operated from the generator must be properly grounded by use of a third wire or be double insulated.
