Copper and Aluminum Wire - Max Amps vs. Gauge

Maximum current in copper and aluminum wire.

Example - Maximum Current in 6 mm² Aluminum Wire

6 mm² aluminum wire is somewhere between AWG #9 and #10. To be on the safe side we use AWG #10 (the smallest one) in the figure above and estimates the maximum current to be approximately 30 amps.
