Star delta convertible connector and method of operating the same

A convertible electrical connector selectively configurable between a star configuration and a delta configuration in a three-phase power distribution system, comprising:

• a socket assembly comprising:
• a plurality of receptacles arranged to receive phase conductors, and selectively, neutral conductors;
• and
• a plurality of terminals electrically coupled to corresponding electrical loads;
• and
• an interchange plug removably insertable into the socket assembly in at least a first orientation and a second orientation distinct from the first orientation;
• wherein the interchange plug comprises at least one conductive busbar positioned such that:
• when the interchange plug is inserted into the socket assembly in the first orientation, the busbar electrically interconnects selected terminals to establish phase-to-neutral electrical connections corresponding to the star configuration, and
• when the interchange plug is inserted into the socket assembly in the second orientation, the busbar electrically interconnects selected terminals to establish phase-to-phase electrical connections corresponding to the delta configuration,
• such that conversion between the star configuration and the delta configuration is achieved without rewiring or disassembly of the socket assembly.
