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. Circular mil means the area of a circle 1 1000 inch in diameter. Awg 4 3125 ln mm2 17 16 approx interpolated awg 4 3125 ln inch2 10 74 approx interpolated logical awg numbers are based on continuing the series in a logarithmic relationship to the cross sectional area of the wire.
