PROBLEM TO BE SOLVED: To prevent apparatuses vulnerable to noise from malfunctioning due to noise by contriving wiring construction inside a switchboard in which apparatuses vulnerable to noise are arranged being mixed with noise-producing apparatuses. SOLUTION: Separated from each other, a third vertical wiring duct 13 for keeping electric wires for circuits vulnerable to noise, and a fourth vertical wiring duct for keeping electric wires for circuits strong against noise or producing noise are provided. Furthermore, in units to be inserted into the switchboard too, a third horizontal wiring duct for keeping electric wires for circuits vulnerable to noise, and a fourth horizontal wiring duct for keeping electric wires for circuits strong against noise or producing noise are provided, being separated from each other. By doing this way, it becomes possible to prevent noise from being induced in circuits vulnerable to noise and to prevent the circuits from malfunctioning. Furthermore, electric wire leading-in work is facilitated by providing a vertical wiring duct cutout in the joint section between a horizontal wiring duct and a vertical wiring duct. |
