What gauge is a wire?
What is Wire Gauge. You might already know this, but simply put, the gauge of a wire is just how thick it is. Most extension cords will range from 10-gauge to 18-gauge with some exceptions. The lower the number, the thicker the wire is. That means that a 10-gauge wire is thicker than a 18-gauge wire. Lower-gauge wires allow for higher currents.
Why use larger gauge wire?
As wire gauge increases, it’s able to carry more current, or amperage (amps). Larger tools, such as table saws and air conditioners will draw more amps. So in these kinds of situations where more amps are required you would use larger gauged wire.
Why is an undersized extension cord bad?
First off, it can lead to a lot of heat and a fire if it’s used for an extended period of time. Since the wire isn’t large enough to carry the current, it will overheat. If the wire is in a coil, then it will heat up even faster.
Why don't you assume the gauge?
Don’t assume the gauge just because the cord powers a certain tool or item. Pro Tip: Most, if not all power tools will have a sticker, plate or placard on it that tells you how many amps it requires. Use this to determine what gauge extension cord to use.
