PROBLEM TO BE SOLVED: To easily form openings at accurate positions by displaying opening effective dimensions for the side boards, rear board, and door of a box body. SOLUTION: An electrical equipment housing box 1 is composed of a box body and a door. Openings are formed at arbitrary positions of the box body and the door, and used for inserting wires into and from the box body, and for fitting equipment and parts for a panel. Fitting metallic parts for an equipment fitting board are welded to the rear board 3 of the box body. Opening jigs 5 having openings at openable parts are affixed to the housing box 1. The opening jigs 5 display opening dimensions not only for the rear board 3 of the box body but also for its side boards 6 and door. When an opening is formed for inserting wires into or from the box body and for fitting equipment and parts for a panel, the shape of the opening is marked by adjusting an opening jig 5 to a plane, and an opening is formed at an arbitrary position. Consequently, easy formation of opening becomes feasible, without measuring the opening dimensions, and shortening of working time for forming the opening of the electrical equipment housing box becomes feasible. |
