PROBLEM TO BE SOLVED: To provide a bus duct branch system capable of easily mounting a tap-off branch structure later.;SOLUTION: A bus duct branch system includes a bus duct 10 having a plurality of conductive connection members 121 in a housing and a branch device 20 in which a plurality of branch conductors 40 are protruded downward. When the branch device 20 is mounted onto the bus duct 10, each of the plurality of branch conductors 40 is adapted to abut on the corresponding conductive connection member 121 of the bus duct 10. Further, the branch device 20 is provided with a fastening tool 45 and a pressing member 43 capable of collectively fastening the plurality of branch conductors 40 and the plurality of conductive connection members 121 when being mounted onto the bus duct 10.;SELECTED DRAWING: Figure 5;COPYRIGHT: (C)2018,JPO&INPIT
