I'm going to be running a 100A subfeed underground through PVC conduit into a newly-built detached garage where the customer will eventually need to use an electric car charger outlet, which calls for 50A. I decided to sell them on a 100A panel in the garage. I've seen some tables in the NEC where it limits #4 copper to 95 amps (or even 85 amps). Yet, there is another table elsewhere that permits 100 amps if used for a feeder.
Would you go with #2 or #4 AWG for this installation? I prefer to use copper, rather than aluminum conductors.
