The present invention relates to a distribution board which comprises: a cabinet formed a space inside; an inner partition disposed inside of the cabinet, and dividing a front transformer room and a rear cable room; a transformer placed in the front transformer room; and a transformer room door installed in the cabinet, and opening/closing the front transformer room. The inner partition includes: a partition body forming a bushing penetration hole in which a bushing is disposed to penetrate, and forming an opening part through which an arc can pass; and an inner cover rotatably connected to the partition body so as to open/close the opening part, in the case of an arc accident, rotated by the arc pressure, and opening the opening part. The distribution board decreases a pressure of the front transformer room by diffusing the arc of the front transformer room to the rear cable room, minimizes forced opening of the transformer door at high speed, and minimizes an accident.
