PROBLEM TO BE SOLVED: To provide a distribution board for housing that reduces the fear that the handle of a branch circuit breaker is wrongly operated. SOLUTION: A cover 20 has a window hole 22 that exposes the bosses 32b of a rectangular frame shape on which handles 32a for operating the branch circuit breaker 32 stored in a body 10 are arranged. The bosses 32b of the branch circuit breaker 32 are arranged inside the body 10 in such a way as to put the rim of the window hole 22 at the front of the cover 20 on almost the same plane with the front-end surface of the bosses 32b. In the branch circuit breaker 32, the handles 32a for opening and closing the contacts inside the breaker unit are arranged o the bosses 32b. The handles 32a, the one end of which is attached pivotally to the breaker unit, are made to be rotatable freely between the positions where they do not protrude from the opening surface of the bosses 32b in the closed state of the contact of the other end and where they protrude from that of the bosses 32b in the opened state of the contact. |
