<P>PROBLEM TO BE SOLVED: To provide a distribution board where the changing work from an 1P type branch breaker to a 2P type branch breaker becomes easier. <P>SOLUTION: A conductive bar 100 connected via a transmission line 97 on power side to the output terminal on power side of a master breaker 6 is connected to the input terminal of a branch breaker 7. The conductive bar 100 has a strip-shaped bar body 101, and branch connecting pieces 102 are a plurality of branch connection parts extended from one side edge in widthwise direction of the bar body 101. An insulating cover 110 covers the exposed section of the branch connecting piece 102 in condition that the conductive bar 100 is connected to each branch breaker 7, and is attached to the bar body 101 of the conductive bar 100. At a section where the branch connecting piece 102 and the bar body 101 are connected with each other, a cutting groove 103 of a cutting auxiliary part is made, and at the insulating cover 110, a cut groove 113 extends to roughly the same position as the cutting groove 103 along the branch connecting piece 102. <P>COPYRIGHT: (C)2004,JPO |
