PROBLEM TO BE SOLVED: To provide a distribution board which neither requires connecting bars in a complicated shape as before, nor increases a dead space in the board. SOLUTION: Orthogonal connections are formed at the tips of bus-bars 2, and a master breaker 1 is arranged vertically to branch breakers 3, by connecting the master breaker 1 to these orthogonal connections. Besides, the master breaker 1 is arranged vertically to the branch breakers 3, by connecting the master breaker 1 to the bus-bars 2 through L-shaped terminal adaptors. By doing this way, it becomes possible to perform positioning of the heavy master breaker 1 easily, to prevent an excessive force from being applied to a plug connection because of imperfect positioning and to prevent them from deforming. |
