Abstract
The present invention provides an electrical power distribution system that includes a first primary distribution panel (PDP) connected to a first source of electrical power and a second PDP connected to a second source of electrical power. The second PDP is connected to the first PDP by a conductor. A first ELCU receives signals corresponding to the flow of current through the first PDP to a load. A second ELCU receiving signals corresponding to the flow of current between the first PDP and the second PDP and a third ELCU receives signals corresponding to the flow of current between the second PDP and the first PDP. The first, second and third ELCUs protect the electrical power distribution system from a variety of fault conditions.
