PURPOSE:To prevent miswiring and to facilitate wiring by determining colors beforehand which correspond to the kinds of loads to be connected to cables, and painting the sheaths of the cables with these corresponding colors. CONSTITUTION:Each cable of a bundle 10 of cables has a sheath with a color which corresponds to the kind of a load; for example, white for lighting fittings, yellow for switches, and gray for outlets; and these cables are bundled and both ends are fitted to wire fastenings 11. The fastenings 11 are fitted to a side of a ceiling frame 12 for example. The ceiling frame 12 is fitted to the upper face 14 of a unit 13. A white cable 10a is drawn out for the wiring of a ceiling lighting fitting 15 from the wire fastening 11, a yellow cable 10b for a wall switch 16, and a gray cable 10c for an outlet 19. This prevents miswiring and rapid and efficient wiring can be realized. |
