PURPOSE:To improve the reliability on a distribution board and also, improve work efficiency and besides, enable it to be manufactured at low cost by forming a base plate in the shape of a recess or a projection thereby providing an upper stage and a lower stage, and extending integrated reinforcing plates downward, respectively, from the upper stage or the lower stage. CONSTITUTION:A base plate 2 provided between inside machine mounting rails 1 is made in the shape of, for example, a recess, whereby an upper stage 2a and a lower stage 2b are formed, and also integrated reinforcing plates 3 are extended downward from the upper stage 2a and the lower stage 2b. A breaker 4 is installed on the upper stage 2a, and also a support stage 6 where a copper bar 5 is fixed is provided on the lower stage 2b. Hereby, the reliability on a distribution board 7 improves, and also the work execution property improves, and the manufacture can be made at a low price. |
