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.

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; anddisconnecting or disabling the electrical power through the primary output for at least one of the electrical systems. 2. The method of claim 1, wherein feeding power from the power source through the feed output to one or more of the electrical systems comprises backfeeding power through at least one rack power distribution unit for at least one of the electrical systems. 3. The method of claim 1, wherein the source power is received from a floor power distribution unit coupled to the input. 4. The method of claim 1, further comprising providing overload protection in one or more lines for the power being fed through the feed output to the at least one electrical system. 5. The method of claim 1, wherein 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 comprises: coupling the input of a feed unit to the feed output of the Y-connection;coupling one or more feed cables to the at least one electrical system; andcoupling the one or more feed cables to an output of the feed unit. 6. The method of claim 5, wherein coupling the one or more feed cables to the at least one electrical system comprises: coupling a first feed cable to a first set of electrical systems; andcoupling a second feed cable to a second set of electrical systems; andwherein coupling the one or more feed cables to an output of the feed unit comprises:coupling the first feed cable to a first receptacle of the feed unit; andcoupling the second feed cable to a second receptacle of the feed unit. 7. The method of claim 1, further comprising performing at least one maintenance operation on the power distribution system while primary power is disconnected or disabled and the feed is supplying power to the systems. 8. The method of claim 7, wherein power from the primary output to at least one of the electrical systems is provided through an automatic transfer switch configured to alternately supply power from the primary output or from a reserve power system, wherein performing the at least one maintenance operation comprises replacing or repairing the automatic transfer switch while the at least one electrical system is being supplied with power through the feed output. 9. The method of claim 1, further comprising performing at least one reconfiguration of the power distribution system while primary power is disconnected or disabled and the feed is supplying power to the systems. 10. The method of claim 1, further comprising: performing at least one maintenance operation or reconfiguration of the power distribution system while primary power is disconnected or disabled and the feed is supplying power to the systems;reconnecting or re-enabling the primary power after performing the at least one reconfiguration or maintenance operation; anddisconnecting the feed after primary power has been reconnected or re-enabled. 11. The method of claim 1, wherein the feed bypasses at least one overload protection device for a rack power distribution unit supplying power to at least one of the electrical systems, the method further comprising performing maintenance on or resetting the overload protection device. 12. The method of claim 1, wherein the power source is a primary power system for at least one of the electrical systems. 13. The method of claim 1, wherein the power source is a reserve power system for at least one of the electrical systems. 14. A system for supplying power during reconfiguration or maintenance of a power distribution system, comprising: a Y-cable comprising an input, a primary output, and a feed output, wherein the input is configured to couple with a power source and the primary output is configured to supply power from the power source to one or more electrical systems; anda feed device comprising: a feed input configured to couple with the feed output of the Y-cable; anda feed output configured to couple with one or more rack power distribution units coupled to at least one of the electrical systems, wherein the feed output is configurable to supply power from the power source to the at least one electrical system. 15. The system of claim 14, wherein the primary power source comprises a floor power distribution unit, wherein the Y-cable input is configured to couple with the floor power distribution unit to receive primary power. 16. The system of claim 14, wherein the feed output is configured to couple in an output receptacle of at least one of the rack power distribution units to backfeed power to electrical systems coupled to one or more other output receptacles of the rack power distribution unit. 17.
