System and method for establishing a power feed from a source panel

摘要

A method of maintaining electrical power to electrical systems in operation during reconfiguration or maintenance of a power distribution system for the electrical systems includes providing a Y-connection in a set of electrical power lines. The Y-connection includes an input, a primary output, and a feed output. The set of electrical power lines supplies electrical power from a power source to the electrical systems through the primary output. To establish a feed for maintenance or reconfiguration of the power feed, power is fed from the power source through the feed output of the Y-connection to the electrical systems while power is being supplied to the electrical systems through the primary output.

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.
