Aluminum conductor sized same as copper table 310.16?

[designer82]

So in table 310.16 I go to the 75°C column to select my appropriate copper cable for the required ampacity.
Do you do same thing for the aluminum side? (from 75°C column same way?)

Do you do same thing for the aluminum side?

Yes. The aluminum column to to the right and will have lower ampacities for the same size copper conductors in the same insulation temperature column.
