From a circuitry stand point, does it make a difference where the Grounding electrode conductor is attached to service entrance conductors in cases where the service entrance conductors are reduced in size.
For instance a 200a service feeds a two-flat, 3 (Otts?) feed the meter bank from the weatherhead, and then #3s feed each individual panel. If the GEC is connected to the neutral in one of the panels is this different from a circuitry standpoint than if the GEC was attached in the metersocket?

Since the GEC is sized according to the largest set of SE conductors, it would seem only right to make the connection at the largest set. The Handbook (Iknow it's not code) shows arrangements contrary to my statement. Please enlighten me.
