<P>PROBLEM TO BE SOLVED: To provide a distribution board which can easily cope with the situation without requiring replacement of a branch bar even if a unipolar branch breaker is arranged or a bipolar branch breaker is arranged. <P>SOLUTION: An inner receptacle block 2 has a plurality of branch breakers 20 within a box 1. A plurality of branch bars 23-26 are arranged to parallel the side of the input terminal 4 of the inner receptacle block 2, and have branch connections 32 and screw threading holes. Trunk bars 27-30 have slots 43 extending in the longitudinal direction of the branch bars 23-26. A connecting screw 49 is threaded into the screw threading hole of the branch bar and the slot 43 of the trunk. For a nut, its thread part to be screwed with the tip of the connecting screw 49 is decentered in the longitudinal direction of the branch bar from the center. An insulating member 52 has a storage recess which houses the nut 56 reversibly. <P>COPYRIGHT: (C)2007,JPO&INPIT |
