NEC 2011, Table 310.60(C)(68)
Ampacities of insulated single aluminum conductor cables Triplexed in air based on conductor temperature of 90*C (194*F) and 105*C (221*F) and ambient air temp of 40*C (104*F).
#8) 50 amps
#6) 70
#4) 90
#2) 125
#1) 145
#1/0) 170
#2/0) 195
and so on.Note.
Refer to 310.60(C)(4) for the ampacity correction factors where the ambient air temperature is other than 40*C (104*F).So in States where the ambient air temp is know to get higer than 40*C (104*F) the Ampacity rating of the AL wire is adjusted down.
