PROBLEM TO BE SOLVED: To provide a distribution board in which sufficient insulation distances of connection bars can be obtained without using a large enclosure and using an insulating cover. SOLUTION: A distribution board has an enclosure 8, a main breaker 1, a branch breaker 3, main bars 2a-2c and connection bars 4a-4c with which the main bars 2a-2c are connected to the output terminals 6 of the main breaker 1. The middle part planes of the voltage side connection bars 4a and 4c which are connected to the output terminals 6 of both sides of the breaker 1 are perpendicular to the bottom 7 of the enclosure 8, The middle part plane of the neutral side connection bar 4b which is connected to the center output terminal 6 of the main breaker 1 is in parallel with the bottom 7 of the enclosure 8 and so placed as to have more distance than the voltage side connection bars 4a and 4c. |
