I have two sets of 350 kcmil incoming service entrance conductor to service disco. GEC size based on 350 kcmil which is 1/0 AWG CU or based on 350x2 = 700 kcmil which is 2/0AWG CU?

All reference based on NEC 2014. Thanks for input
 
Greetings, I would like to consult: if I apply the temperature adjustment factors and number of conductors, based on 310.16 at 90 ° C, but the terminals of the device are for 75 ° C. So I have to choose 310.16 at 75 ° C?

You may calculate using the 90 deg rating, but your final result does not allow you to exceed the 75 deg rating.
