🔌 AWG Wire Gauge Reference Table
American Wire Gauge (AWG) is the standard for electrically conductive wire in North America. Counterintuitively, lower AWG numbers indicate thicker wire. The table below covers AWG 0000 through 30 with diameter, resistance, and typical ampacity.
Safety Notice: Ampacity values are approximate guidelines for insulated copper wire at 60°C. Always consult the NEC (National Electrical Code) and a licensed electrician for electrical installations.
