PROBLEM TO BE SOLVED: To provide a copper bus bar which is simple of assembly and is generally inexpensive by screwing a plurality of sub bus bars, which have three to four branching and connecting feet and through holes for screws at sub copper bus bar parts, to a main bus bar. ;SOLUTION: Sub-bus bar blocks 7 and 7' have a plurality of branching and connecting feet 702 and 702 to be connected to the terminals of branch breakers, and through holes 703 and 703' at sub copper bus bar parts 701 and 701', and with a rated current as 60A, one sub copper bus bar part is provided with three to four branching and connecting feet. Moreover, though the sub bus bar blocks 7 and 7' are fixed continuously into the screw holes 801 and 801' of the main bus bar 8, by screws 9 and 9', the capacity of current application is made 60A-100A. Then, for the copper bus bar, a power cable 10 is fastened into the screw hole 801 together with its screw through hole 703 so as to supply power, and the branching and connecting feet 702 and 702' are connected to the terminals of breakers, and the power is branched separately for each circuit of each branching breaker. As a result, as a whole, it can be made inexpensive by improving the yield of the material, and also the assembly can be simplified.;COPYRIGHT: (C)1997,JPO
