Electrical Cable Sizes 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.

Electrical cable sizes chart.

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. It can also be used for american awg or metric mm 2 sizing this calculation is applied to typical dc circuits and a few simple ac circuits. 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. Wire is sized by the american wire gauge awg system.

Common sizes include 14 12 10 8 6 and 2 gauge wire. 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.
