For longer distances it may be necessary to increase wire diameter - reducing the gauge - to limit voltage drop. The higher the gauge number, the smaller the diameter, and the thinner the wire.īecause of less electrical resistance a thicker wire carries more current with less voltage drop than a thinner wire. Values for resistance are based on electrical resistivity for copper 1.724 x 10 -8 Ω m (0.0174 μΩ m) and electrical resistivity for aluminum 2.65 x 10 -8 Ω m (0.0265 μΩ m). It is also known as the Imperial Wire Gauge or British Standard Gauge.

Always check the manufactures data before detailed engineering.įor full table with Single Core and Multi Core Current Ratings - rotate the screen!ĪWG - American Wire Gauge Current Ratings AWG Operating temperature of the conductor, ambient temperature and type of conductor insulation is important. Be aware that the current load depends on installation method - the enclosure - and how well the resistance heat is removed from the cable. The table below indicates the current ratings of PVC-insulated single and multicore wiring cables. Telephone wire is typical AWG 22, 24, or 26. Typical household wiring is AWG number 12 or 14. The higher the number - the thinner the wire. Because of the small gaps between the strands in a stranded wire, a stranded wire with the same current-carrying capacity and electrical resistance as a solid wire, always have a slightly larger overall diameter. American wire gauge (AWG) is a standardized wire gauge system for the diameters of round, solid, nonferrous, electrically conducting wire. The AWG table below is for a single, solid, round conductor. AWG is sometimes also known as Brown and Sharpe (B&S) Wire Gauge. These factors play an integral role in identifying the best wire for your given application.īelow, we've included a chart of wire gauges for your reference.The AWG - American Wire Gauge - is used as a standard method denoting wire diameter, measuring the diameter of the conductor (the bare wire) with the insulation removed. Wire gauge dictates the amount of electric current a wire can safely carry, its electrical resistance, weight, and other key characteristics. Wire gauge, or the measurement of a wire's diameter, is an extremely important measurement for your determining your project's choice of wire.
