I agree with Dennis but if your using a 75 degree C conductor with 75 degree C terminals you can use #3. You could use the #4 with a 90 amp OCPD.

It's a Con Ed specification cable, 10 conductors (10 point) all #9 AWG stranded conductors. Yup that is correct, each conductor is labeled #9 AWG with a special 10-point meter color code.

We always do. We just do not connect the Ct's leaving the meter wire for the POCO but we wire the meter pan.

Yes derating is required because you have more than 3 CCC in a single raceway. Good news is that you can still use #12 AWG conductors.

#12 THHN = 30 amps @90 degrees C
30 amps*70% = 21 amps...
