Service entrance wire should be AWG #3 copper.
Need to know what size service is going to be installed at the end of the run.
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.
#6 bare copper wire.
Service entrance wire should be AWG #3 copper.
For a 100 amp service, a common feeder wire size would be 2 AWG (American Wire Gauge) copper or 1/0 AWG aluminum. These sizes are appropriate for handling the current capacity needed for a 100 amp electrical service. It is important to consult with a licensed electrician or local building code requirements to ensure the proper wire size for your specific installation.
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.
why we are using thick size of feeder cable in tele network?
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).
