PROBLEM TO BE SOLVED: To provide a branch bar capable of switching voltages easily without using different branch bars in a single phase three wire distribution board. SOLUTION: One end of a bar body 6 is used as a connection end part 6a to be connected to a breaker 4. A screw connection part 6c to be connected to an N-phase bus bar 2 is provided at a position near to the other end, while a screw connection part 6e to be connected to an L2 -phase bus bar 3 or an L1 -phase bus bar 1 is provided at this end thereof. These screw connection parts 6c and 6e have a dislocated from to a vertical direction and to an elongated direction of the bus bar 1 or 3. When the connection at 200V is carried out, the bar body 6 in an inverse state is used. |
