PROBLEM TO BE SOLVED: To reduce the longitudinal lengths of main bars and reduce the size of a distribution board by a method wherein the end parts of transfer bars which are laid along the side surface of a main breaker and the main bars cross each other at right angles and the main bars and the transfer bars are connected to each other at the crossing parts. SOLUTION: The respective one side ends 29a-29c of three transfer bars 4a-4c are connected to the output terminals 6 of a main breaker 1. The respective other ends 30a-30c are extended along the side surface of the main breaker 1. The other ends 30a-30c are attached to an attaching surface so as to be in parallel with each other and made to cross the end parts 28a-28c of main bars 2a-2c. The transfer bars 4a-4c and the main bars 2a-2c are connected 31a-31c to each other at the crossing parts of the other ends 30a-30c of the transfer bars 4a-4c and the main breaker 1 side end parts 28a-28c of the main bars 2a-2c. With this constitution, the longitudinal lengths of the main bars of a distribution board can be reduced, so that the size of the distribution board can be reduced. |
