Wire Gauge Chart

Wire gauge, or the measurement of a wire's diameter, is an extremely important measurement for your determining your project's choice of wire. Wire gauge dictates the amount of electric current a wire can safely carry, its electrical resistance, weight, and other key characteristics. These factors play an integral role in identifying the best wire for your given application.
