Japanese Patent JP7149020
Kind Code:
B2
Abstract:
To provide a panelboard having high convenience.SOLUTION: A panelboard 100 is provided with: a trunk switch 110 in which a cable way is blocked through trip operation during abnormality in an electric conduction state; and a plurality of branch switches 130 connected to the output side of the trunk switch 110. The panelboard 100 is further provided with a branch electric conduction detection unit 140 in which presence or absence of abnormality in the electric conduction state in the branch switches 130 is detected to output a branch electric conduction signal D2. The branch switches 130 have a branch relay 131 electrically controlling switching of the cable way based on the branch electric conduction signal D2. Furthermore, a communication unit which transmits the detection result of the branch electric conduction detection unit to the outside is included.SELECTED DRAWING: Figure 19
