PROBLEM TO BE SOLVED: To provide a distribution board which can be manufactured with a few kinds of components but is suitable to many sizes, thereby eliminating the complexity in management of components. SOLUTION: In a distribution board 1, rail fixtures 3 are mounted at proper places in a rear face 2a of the main body 2 of a box which has its front face opened, and rails 4L, 4R are set on the rail fixtures 3. The rails 4L, 4R are used in sets of two and each pair of the rails are installed parallel in the horizontal direction. Equipment installation panels 5 are installed between the rails 4L and 4L, 4R and 4R, and electronic equipments are fastened onto the equipment installation panels 5 and then the electric equipments are wired to form a left internal machine 6 and a right internal machine 7. Between the adjacent rails 4L and 4R which are between the left internal machine 6 and the right internal machine 7, a supporting metal fitting 8 is installed. The supporting metal fitting 8 is provided with a partition wall 9 to separate the left internal machine 6 and the right internal machine 7 and then the left internal machine 6 and the right internal machine 7 are covered with a wiring protective board 11 supported by a supporting pole for protecting the wiring. The supporting metal fitting 8 is constituted of base metal fittings 12 which connect the adjacent rails 4L and 4R which are located between the left internal machine 6 and the right internal machine 7 and an adjustment metal fitting 13 for adjusting the insallation height of the rails 4L, 4R. |
