Abstract:
1. A method of maintaining electrical power to electrical systems in operation during reconfiguration or maintenance of a power distribution system for the electrical systems, comprising: providing a Y-connection in a set of electrical power lines, wherein the Y-connection comprises an input, a primary output, and a feed output, wherein the primary output and the feed output share a common electrical connection to the input via one or more branched conductors, wherein the set of electrical power lines is configured to supply electrical power from a power source to the electrical systems through the primary output; feeding power from the power source through the feed output of the Y-connection to at least one of the one or more electrical systems while power is being supplied to the electrical systems through the primary output; and disconnecting or disabling the electrical power through the primary output for at least one of the electrical systems.
