Cable gauge size calculator.

American wire gauge awg also known as the brown sharpe wire gauge 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. The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 volts 60 c through 90 c 140 f through 194 f not more than three current carrying conductors in raceway cable or earth directly buried based on ambient air temperature of 30 c 86 f. For example to see the effective gauge of a cable made from 10 20 gauge wires select 20 gauge from the drop list then type 10 into the number of wires field and press the tab key. Today we are here with another comprehensive copper and aluminum wire size calculator as we have discussed in detail the topic of how to calculate the proper wire size for electrical wiring.

Wire is sized by the american wire gauge awg system. For the 00 000 0000 etc. Common sizes include 14 12 10 8 6 and 2 gauge wire. Wire gauge calculations wire diameter calculations.

Second multiply the diameter by 1000 to find the area in kcmil or by 3 1415 4 to calculate square millimeters. Now you can take the advantage of this calculator to do this job j you can also check the classical wire cable size calculator in awg calculating wire cable size formula for single phase circuits. This website provides a wire size calculator voltage drop calculator wire ampacity charts and more. The requirements of the national electrical code nec and local codes must always be followed.

Wire gauge refers the physical size of the wire rated with a numerical designation that runs opposite to the diameter of the conductors in other words the smaller the wire gauge number the larger the wire diameter. The cross sectional area of each gauge is an important factor for determining its. D n in 0 005 in 92 36 n 39. The n gauge wire diameter d n in millimeters mm is equal to 0 127mm times 92 raised to the power of 36 minus gauge.

Gauges you use 1 2 3 which makes more sense mathematically than double nought. The combination is equivalent to a single 10 awg gage. To determine the effective awg gage of multiple small wires a particular gage. Awg wire sizes see chart below awg.

The n gauge wire diameter d n in inches in is equal to 0 005in times 92 raised to the power of 36 minus gauge number n divided by 39. Wire gauge diameter area and resistance chart. Dimensions of the wires are given in astm standard b 258. First find the diameter of the wire.

In the american wire gauge awg system wire size diameters can be calculated by applying the formula d awg 005 92 36 awg 39 inch.
