Printable AWG Ampacity Chart
This one-page Letter PDF is for electricians, installers, and anyone checking copper wire current ratings. It lists typical US NEC ampacity values for AWG sizes in three temperature columns: 60 °C, 75 °C, and 90 °C. Sample rows include 1 AWG, 2 AWG, and 3 AWG with amps shown in each column. A note on the sheet states the table assumes not more than 3 current-carrying conductors and 30 °C ambient, and that code limits and corrections still apply.
