MODULAR ELECTRICAL SYSTEM INCLUDING BACK-TO-BACK RECEPTACLE CONFIGURATIONS AND CAPABLE OF PROVIDING FOUR WIRE CIRCUITRY
A modular electrical system ( 230 ) comprises a number of separate components forming a four-wire system ( 110 ). The component set ( 230 ) includes receptacle junction blocks ( 130 ), two-way connectors ( 232 ), four-way connectors ( 236 ), two-way jumper cable assemblies ( 234 ), and three-way jumper cable assemblies ( 238 ). The components of the component set ( 230 ) include various configurations of male blade terminals ( 150 ) and female terminals ( 200 ) located on the individual components so that a number of differing system configurations can be achieved.
1 . An electrical system adapted for use in a raceway for providing an electrical power distribution system for supplying power through receptacles for purposes of energizing power-driven devices, the electrical system comprising:
a female end connector having a series of four electrical wires, with one of the wires being a neutral, one of the wires being a ground and two of the wires being hot wires;
a male end connector having a series of four electrical wires, with the electrical wires comprising a neutral, a ground, and two hot wires;
a series of female terminals, each of said terminals being conductively connected to a terminating end of one of the wires of the female end connector;
a series of male terminals, each of said male terminals being connected to one of said electrical wires of said male end connector;
a series of four bus bars positioned intermediate said female end connector and said male end connector, and conductively connected to each of said electrical wires of said female end connector and to each of said electrical wires of said male end connector; and
terminal means connected to said bus bars and adapted to be received within a receptacle housing, so as to selectively apply electrical power to said power-driven devices.
