<P>PROBLEM TO BE SOLVED: To provide a unit cable for houses by two-by-four construction capable of preventing lowering of the strength of joists by reducing hole boring works into the joists, and capable of shortening a construction period for electrical wiring works by reducing mandays for electric-wire passing works. <P>SOLUTION: A plurality of VVF cables 3(12) for power source lines for performing connection between joint boxes 2(11), a plurality of VVF cables 4(13) for branch wiring for supplying power to a plurality of outlets respectively, and VVF cables 5(14) for connection each of which is connected to a bayonet connector 6(15) for connection at one end, are arranged in parallel. Circuit connection is performed by respectively connecting the conductors of the VVF cables 3(12) for power source lines, the conductors of the plurality of VVF cables 4(13) for branch wiring, and the conductors of the VVF cables 5(14) for connection. The connected parts are insulated and put in joint boxes 2(11), thermosetting resin is injected into the joint boxes 2(11) to perform sealing, and the bayonet connectors 6(15) for connection are put in the joint boxes 2(11). <P>COPYRIGHT: (C)2006,JPO&NCIPI |
