The correct answer is: C. Feeders
Feeders are the conductors that connect the consumer’s terminals to the distribution system. They are typically larger than branch circuits and are used to carry power over longer distances.
Distributors are the conductors that connect the substation to the distribution system. They are typically larger than feeders and are used to carry power over even longer distances.
Service mains are the conductors that connect the distribution system to the consumer’s premises. They are typically the largest conductors in a distribution system and are used to carry power from the distribution system to the consumer’s equipment.
None of the above is the correct answer because it does not identify the conductors that connect the consumer’s terminals to the distribution system.
