#US WIRE GAUGE CHART SKIN#

Table 1: American Wire Gauge (AWG) Cable / Conductor Sizes and PropertiesĪWG Notes: American Wire Gauge (AWG) is a standardized wire gauge system used predominantly in the United States to note the diameter of electrically conducting wire. A detailed description of each conductor property is described below Table 1.

The resistances and skin depth noted are for copper conductors. In addition to wire size, the table provides values load (current) carrying capacity, resistance and skin effects. Table 1 lists the AWG sizes for electrical cables / conductors. American Wire Gauge (AWG) Sizes and Properties Chart / Table Note – W&M Wire Gauge, US Steel Wire Gauge and Music Wire Gauge are different systems. AWG general rules of thumb – for every 6 gauge decrease, the wire diameter doubles and for every 3 gauge decrease, the cross sectional area doubles. The smallest AWG size is 40 and the largest is 0000 (4/0). The larger the AWG number or wire guage, the smaller the physical size of the wire. ambient temperature 45 – 50 oC: correction factor = 0.58Īmerican wire gauge (AWG) is a standardized wire gauge system for the diameters of round, solid, nonferrous, electrically conducting wire.ambient temperature 4 1 – 45 oC: correction factor = 0.71.ambient temperature 31 – 40 oC: correction factor = 0.82.

Correction-factors at ambient temperature above 30 oC 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. Current Load Ratings – Copper (amps) 1)ġ) Current ratings for up to 1000 V, PVC-insulated single and multicore wiring cables, ambient temperature up to 30 oC
