what is needed to use a generator on a house
If you use an undersized cord, you can potentially damage the generator and appliances. For example, the most common size for generator use is 14, 12 and 10 gauge. The smaller the gauge number, the thicker the cord and the more electricity it can carry. Extension cords have several other drawbacks. First, most extension cords can't be plugged into a furnace, well pump, or ceiling-light fixture.
