Claims

[Scope of Claim for Utility Model Registration] In a power distribution board for indoor wiring that has a plurality of branch circuits connected from the power source side to loads in different areas via a watt-hour meter and a terminal block, the plurality of terminal blocks are connected to a power distribution board case. The terminal block includes a first terminal board having first and second connecting parts for connecting conductors at both ends thereof, and a first terminal board having first and second connecting parts for connecting conductors at both ends thereof, a second terminal board disposed adjacent to the board and having third and fourth connection parts at both ends for connecting conductors, respectively; connecting portions are connected to the same branch circuit, the first connecting portion can be selectively connected to the watt-hour meter, and a selective connecting portion is connected between the first connecting portion and the third connecting portion. A power distribution board, characterized in that a short-circuiting conductor can be connected to the short-circuiting conductor, and one or more branch circuits connected to one of the watt-hour meters can be appropriately selected by the short-circuiting conductor depending on the usage pattern of the branch circuit. .
