I finished a fourplex four meter pack with four disconnects on one enclosure.And i have four 60Amp feed through one conduit to each subpanel that are installed side by side in a 36"x48" enclosure. I have pulled only one #10 EGC that is being daisy chained from one panel to the next. I have a feeling that i need four #10EGC. Am I correct?
Please show NEC reference because i can not find it.
250.122(C) Multiple Circuits. Where a single equipment grounding conductor is run with multiple circuits in the same raceway or cable, it shall be sized for the largest overcurrent device protecting conductors in the raceway or cable.
Not sure the power company will be happy with the feeders from 4 different meters to all be in the same conduit.

As I read it, you are only required to have on GEC (wire to a ground rod). The utility neutral, however, must be bonded to the case of each of the disconects- so the egc will terminate to the neutral buss at each disconnect as well.
