PROBLEM TO BE SOLVED: To provide a distribution board where even if two or more kinds of breakers are mixed, they can be connected with one another at low cost, in a plug-in type distribution board which has a bus bar vertical to the board face. SOLUTION: A plug-in type adaptor 6 is inserted from above the bus bar 2 vertical to the board face 4 so as to constitute a branch circuit part comprising a branch bus bar 15, etc. on the topside. The adaptor 6 is composed of a case 7 and a replaceable connecting bar 8. The layout of the branch bus bar 15 has a free choice: it may be parallel with or vertical to the main bus bar 2. A part of the branch bus bar 15 may extend outward from the adaptor 6. COPYRIGHT: (C)2005,JPO&NCIPI
