Definition from the National Electrical Code Article 100:Feeder. All circuit conductors between the service equipment, the source of a separately derived system, or other power supply and the final branch-circuit overcurrent device.Branch Circuit. The circuit conductors between the final overcurrent device protecting the circuit and the outlet(s).
For service sizes of 100 amps and less a #8 bare copper conductor is required.
As a service entrance wire you need AWG # 3/0 gauge copper.
Service entrance wire should be AWG #3 copper.
Service wire for 100 amps requires AWG #3 copper.
why we are using thick size of feeder cable in tele network
A #3 copper conductor with an insulation factor of 90 degrees C is rated at 115 amps.

500
Ground is sized based on the size of the feeder wire and not the amps of the service! However, for a 600 amp service 1500MCM copper wire is one option (NEC 310.16) ;therefor, ground wire is 3/O copper (NEC 250.66) or another option is a two sets of 350 MCM copper wire then a #2 copper (since the biggest feeder wire is 350MCM).
