The conductor connecting consumer's terminals to the distributor is called the
Feeder
Distributor
Service main
None of the above
Service main
The service main is the final link in the power distribution system that connects the distributor (or the pole) to the consumer's premises. It acts as the bridge that feeds electricity from the utility network to the customer's meter or main switchboard.

VdropтАЛ=I├ЧRsmтАЛ тАФ where RsmтАЛ is the resistance of the service main conductor, determining the voltage drop at the consumer terminal.
In a distribution system, the power flows from the Substation to the Feeder, then to the Distributor. From the distributor, tapping points are provided, and a 'Service Main' conductor is run to the consumer's service entrance point. It is typically designed to carry the total connected load demand of a single consumer or a small group of consumers.
The service main is the final step in the distribution network hierarchy.
It connects the distributor to the consumer's energy meter.
The sizing of the service main is based on the maximum demand and permissible voltage regulation at the consumer's end.
Provides a direct and dedicated path to the consumer's premises.
Easier maintenance for utility providers to disconnect or reconnect supply.
Vulnerable to environmental damage due to exposure in overhead configurations.
If the service main fails, only the specific consumer or specific building loses power, preventing wider system issues.
Residential electrification
Commercial building supply connections
Feeder: Connects the substation to the distributor without any tapping.
Distributor: A line from which power is tapped off for the supply of consumers through service mains.
Service main is the last segment in the sequence: Substation -> Feeder -> Distributor -> Service Main.
C is correct тАФ The service main is the conductor specifically utilized to connect the distributor to the consumer's terminals.
Always remember the order of hierarchy in distribution: Feeders carry the load without taps, Distributors have taps along their length, and Service Mains connect taps to the consumer.
