What are the wires in the primary distribution box called
PRIMARY WIRES, also called conductors, are on top of the pole and carry medium voltage electricity from a substation to the transformer. The simplest primary distribution system consists of independent feeders with each customer connected to a single feeder. Since there are no feeder interconnections, a fault will interrupt all downstream customers until it is repaired. This configuration is called a radial system and is common for. Electric power distribution is the final stage in the delivery of electricity.
