Wire Gauge calculates the minimum required wire gauge for a given wire type, current, and environmental temperature. It includes 20 different insulation types, aluminum or copper, currents ranging from 0 to 750 Amps, and conduit temperatures from 70 to 170˚ F. Wire Gauge is just one of the many features found in Trunnion’s full featured electrical reference app: Elec Ref. We do hope that you’ll upgrade to the deluxe version, Elec Ref, to take advantage of all the great features it offers!
