Wiring system and power distribution cable for balancing electrical loads

A wiring system for distributing three-phase power from a three-phase power supply is provided. The wiring system includes a power distribution cable assembly and a load cable assembly. The power distribution assembly comprises a first power connector head and a second power connector head operatively connected to the respective ends of a length of power cable such that the connection of the power conductors of the respective power terminals disposed in fixed arrays in the respective connector heads is switched. The load cable assembly has a load connector head connected to an end of a load cable. The load connector head has a fixed array of terminals that includes three terminals selected from a group consisting of a first power terminal, a second power terminal, a third power terminal, a neutral terminal, and a ground terminal. The fixed array of terminals of the load connector head is constructed and arranged for releasable connection to one of the fixed arrays of terminals of the second power connector head.
