Wire gauge is a measurement of wire diameter. This determines the amount of electric current a wire can safely carry, as well as its electrical resistance and weight. Dimensions of the wires are given in ASTM standard B 258. Ohms per km, Maximum amps for chassis wiring.
Generally speaking, the smaller the gauge number, the thicker the cable.
This form of measuring cable thickness is used . American Wire Gauge (AWG) versus square mm cross sectional area. Standard Wire Gauge Conversions. What wire size and circuit size is proper for your installation is determined by several factors, including the planned load on the circuit, the number of outlets or light fixtures, and the length of the circuit.
What is critical, though, is that the wire gauge. The gauge of a piece of wire refers to its diameter. The larger the diameter of the wire, the smaller its gauge number.
