Based on the diagram above I would run a # 2 copper GEC based on the following:
IMO based on the definitions of a Service Lateral in article 100, the 600kcmil Al conductors are not service entrance conductors.
The definition of "Service-Entrance Conductors, Underground system, is the service conductors between the terminals of the service equipment and the point of connection to the service lateral.
IMO this would be the connection at the load side of the meter pan.
In the case above, and based on article 100 definitions, the service entrance conductors are 2 sets of 4/0 aluminum conductors. Based on chapter 9 table 8 there will be a total of 211600 cm per conductor with a combined area of 423,200 cm.
Based on table 250.66 this would require a minimum #2 copper GEC.
Opinions?
Thanks,
