The majority of our 6 awg is sold by the foot. Below is our entire selection of 6 awg electrical 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. National electrical code ansi nfpa 70 1999.

Standard set of non ferrous wire conductor sizes. Those products that are sold in spools will have their available lengths listed. 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. The national electrical code nec has a letter system that makes it easy to quickly identify a wire s capabilities.

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. Awg is sometimes also known as brown and sharpe b s wire gauge. Amperage amps versus wire cable size mm to awg ul486e assigned maximum ampere rating versus wire size for copper conductors. The lower the gauge the thicker the wire and the greater its capacity for electrical current.

Wire gauge calculations wire diameter calculations. The higher the awg number the thinner or smaller the wire. D n in 0 005 in 92 36 n 39. Used since 1857 awg has helped users determine a wire s current carrying ratings.

Values are for not more than three conductors in raceway or cable reference. The sheath binds the inner wires together and its outer markings indicate the number of wires and size or gauge awg of wire within the sheathing. American wire gauge size calculator and chart. 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.

Non ferrous includes copper and also aluminum and other materials but is most frequently applied to copper household electrical wiring and telephone wiring. Shop our selection of 6 gauge wire. The color of the sheathing indicates recommended usages. Gauges you use 1 2 3 which makes more sense mathematically than double nought.

The awg table below is for a single solid round conductor. Typical household wiring is awg number 12 or 14. 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. For the 00 000 0000 etc.
