That solution is a parallel feeder distribution system. Using parallel feeders means you're not forcing a huge electrical load through one single point. Instead, this setup intelligently splits the power, giving you a stable and reliable parallel service without. Primary distribution systems consist of feeders that deliver power from distribution substations to distribution transformers. A feeder usually begins with a feeder breaker at the distribution substation. Many feeders leave substation in a concrete ducts and are routed to a nearby pole. In.
