The 2 gauge copper wire in free air (strung from the utility pole) can carry 150 amps. In a cable or conduit coming down to your panel 2 gauge is for 100 amps. Splice on a 1/0 or fatter copper up at the entrance head to bring down 150 amps.

The unequal sized feeders were probably intended to go first to a disconnect switch and then branch to a 120/240 volt single phase subpanel and to a 3 phase subpanel.
