Wire thickness and Current Calculator

AWG: In the American Wire Gauge (AWG), diameters is generally computed by utilizing the formula D(AWG)=.005·92((36-AWG)/39) inch. For the 00, 000, 0000 etc. gauges you choose -1, -2, -3, helping to make more sense mathematically rather than “double nought.” Therefore in American wire gage each 6 gauge drop delivers a doubling of the wire dimension, … Read moreWire thickness and Current Calculator
