American Wire Gauge (AWG) is a logarithmic stepped standardized wire gauge system used since 1857, predominantly in North America, for the diameters of round, solid, nonferrous, electrically conducting wire. Dimensions of the wires are given in ASTM standard B 258. [1] .

In these AWG gauge charts, most common gauge values show the different characteristics of wire such as its diameter, area, ampacity, resistance, current density, fusing current and temperature ratings etc.

12 AWG wire is one of the most commonly used wire sizes in electric engineering. With 25A ampacity at a median of 75°C temperature, it is the best wire to be used for 20 amp services (of course, you have to account for 80% NEC requirement, as we explain later on).

Typical household wiring is AWG number 12 or 14. Telephone wire is typical AWG 22, 24, or 26. The table below indicates the current ratings of PVC-insulated single and multicore wiring cables. Be aware that the current load depends on installation method - the enclosure - and how well the resistance heat is removed from the cable.

Typical household copper wiring is AWG number 12 or 14. Telephone wire is usually 22, 24, or 26. The higher the gauge number, the smaller the diameter and the thinner the wire. The table below can be used to convert American Wire Gauge (AWG) to square mm cross sectional area.
