As lower gauge wires (such as AWG 4) are thicker, they can accommodate more electrons than higher gauge wires (such as AWG 40). Current capacity is a measure of the amount of current a wire can carry safely. 2485Ω for 1000 feet, while AWG 40 wire has a resistance of 1079Ω for 1000 feet.) (e.g., At 25° C, AWG 4 wire has a resistance of. Given two wires of the same length, the thicker wire would have smaller resistance than the thinner wire. Longer wires provide greater resistance than shorter wires. A wire’s electrical resistance depends on its length and thickness. ![]() AWG is determined by first figuring out the radius of a wire. (e.g., AWG 4 wire requires 7.918 feet, while AWG 40 requires 34.364 feet.) Since 1857, wire gauge to MM2 made determining a wires current-carrying ratings easier. Feet per pound refers to the number of feet of wire needed to reach one pound in weight. The wire’s cross-sectional area doubles every time it descends three levels (e.g., a six-gauge wire has double the cross-sectional surface area of a nine-gauge wire). The cross-sectional area of round wires can be calculated using the formula A= πr2, with r representing half of the diameter. The diameter doubles every time the gauge decreases by six levels (e.g., a three-gauge wire has double the diameter of a nine-gauge wire). For example, AWG 4 is 0.2043 inches in diameter, and AWG 40 is. 14 AWG - maximum of 20 Amps in free air, maximum of 15 Amps as part of a 3. The larger the AWG number or wire guage, the smaller the physical size of the wire. ![]() Wire gauges range from low numbers to high numbers, with smaller numbers referring to smaller diameters and larger numbers representing larger diameters. American Wire Gauge Conductor Size Table American wire gauge (AWG) is a standardized wire gauge system for the diameters of round, solid, nonferrous, electrically conducting wire. Given its gauge, industry professionals can determine the following about a particular wire: For 6 volt automotive systems typically a wire gauge 2 sizes larger. The gauge of a wire imparts more than information about its thickness. Using these two numbers, Amps and length, locate the nearest gauge value in the chart below.
