480V 3ph 2000A service from utility
Is there any scenario where you would need 5 conductors from utility's transformer to customer's equipment?
In my mind, the answer is no. Your MBJ is at customer's equipment and this creates your separation of neutral and EGC. Upstream from MBJ, a 5th wire would do nothing for you.
Second guessing...
