Title: NEUTRAL ROUTING FOR MULTIPLE ELECTRICAL POWER SOURCES
Abstract:
In an electrical distribution system for a facility served by two power sources, ground currents on neutral conductors are avoided by utilizing a common neutral conductor in distributing power from both power sources to one or more transfer switches. In at least one single cable or conduit run, either between transfer switches or between both power sources and a transfer switch, line conductors carry power from each power source to the transfer switch(es), and a common neutral conductor carries return current for both power sources. The neutral terminals of both power sources are connected together (in part via the common neutral conductor in the single cable or conduit run), and the common neutral is grounded at only one place.
