In the device, at least one of the input terminal portion and the output terminal portion is provided at a vertical body end portion substantially orthogonal to the horizontal direction in which the plurality of branch switches are arranged inside the residential distribution board, Each terminal of the terminal portion provided at the end portion is aligned along the longitudinal direction. Since is disposed, there is an effect that can be miniaturized so as to approach the lateral dimensions of the device body in substantially equal dimensions to one portion of the terminal. In addition, since the lateral dimension of the body is smaller than that of the conventional one having the same electrical performance, it is necessary to use a residential distribution board having a smaller lateral dimension than the conventional example. Or when using a distribution board for a house of the same size as the conventional one, it is also possible to increase the number of branch switches and to arrange other devices such as a current limiter in the extra space. This has the effect.

According to a sixth aspect of the present invention, in any one of the first to fifth aspects of the present invention, an output terminal portion is provided on one side of the side surface of the body along the longitudinal direction, so that the branch terminal is opened and closed inside the box. The conductor connected to the input terminal of the container and the output terminal can be directly connected, reducing the number of conductor connections inside the box and improving the connection reliability of the distribution board for home use. is there.
