- | American Wire Gauge (AWG) and IEC wire sizes are often hard to correlate. There are many references on the internet, but none that gave enough information to really compare. So I wrote my own reference to compare the area of each size more usefully. | + | American Wire Gauge (AWG) and IEC (mm< |
