Claims

[Scope of Claim for Utility Model Registration] In a low-voltage switchboard in which a plurality of molded circuit breakers are housed horizontally in a vertical line, L-shaped cross-sections are provided at the front and rear ends of the middle part of both sides of the box body, respectively. A cross-sectional rail with a slit-shaped opening in the longitudinal direction, the front and rear two of which are fixed to the inner surfaces of the four main pillars in parallel and at the same pitch, and the above-mentioned rails provided parallel to one side. a plurality of bus bar support cleat mounting plates installed on the rail so as to be movable up and down and having a plurality of bus bar support cleat mounting holes; and a plurality of cable support plates installed on the rails provided in parallel to the other side surface so as to be movable up and down. and one cable pull-out hole provided in the ceiling plate, two square cable pull-out holes arranged in parallel in the floor plate, and three sets of cable hole covers having a two-part structure that cover the cable pull-out holes. A low-voltage power distribution board characterized in that two sets of cable hole covers that cover a square cable pull-out hole among the cable hole covers can freely change the direction of a dividing line in the panel width direction and panel depth direction.
