PROBLEM TO BE SOLVED: To provide a distribution board in which a circuit breaker can be attached and fixed reliably to the middle bottom, even if attachment and fixing release means, i.e., a lock lever, is not located at the attachment and fixing position.SOLUTION: In a distribution board where branch switches 1 attached to a middle bottom 2 are arranged in a cabinet, each branch switch is provided with a lock lever 104 which attaches and fixes the branch switch by engaging with an engaging part 204 provided on the middle bottom, and releases attachment by disengaging from the engaging part. When a cover is attached to a box while the lock lever is at the release position, the lock lever abuts against the back of the cover and displaces from the attachment release position to the attachment and fixing position. |
