PROBLEM TO BE SOLVED: To enable labor saving in cable installation work and enhancement of quality by making in one case a unit of a small current cable with number of branches and length of which are determined in advance in accordance with the wiring route, and making wiring as drawn in a single stroke. SOLUTION: The number of branches and length of a small current cable 1 are determined in advance in accordance with the wiring route, and the cable 1 is turned up and radially branched in the respective direction of wiring within a case 3, such as a branch box. The cable 1 is fed and wired as drawn in a single stroke through a modular jack and an attachment plug 2, and is turned into a unit. Such a wiring is fabricated in advance in a factory and is installed in the ceiling or along wall surfaces after the completion of interior finish work. This installation work is facilitated by bundling in appropriate positions circuit going to and returning from the modular jack 2 or the like. As a result, wiring work on the spot is significantly facilitated, and it is possible to save labor in cable installation work, reduce time of completion, and improve quality. |
