Patent ID: 8134828

Claim:
A fusible panelboard assembly comprising: a chassis configured to interchangeably receive a plurality of fusible switching disconnect modules for protecting branch circuitry, wherein the plurality of fusible switching disconnect modules include a first fusible switching disconnect module having a first switch housing of a first size and a first rectangular fuse module having a first amperage rating or below, the first rectangular fuse module removably insertable to and from the first switch housing, and a second fusible switching disconnect module having second switch housing of a second size and a second rectangular fuse module having a second amperage rating or below, the second rectangular fuse module removably insertable to and from the second switch housing; wherein the first size is less than the second size; and wherein the first amperage rating is less than the second amperage rating; and a configurable branch enclosure cover coupled to the chassis and adapted to surround the plurality of fusible switching disconnect modules; wherein the configurable branch enclosure cover is configurable by a user to accommodate user selected fusible switching disconnect modules, the user selected fusible switching disconnect modules being ones of the plurality of fusible switching disconnect modules; wherein the configurable branch enclosure cover is configurable to receive either one of the first and second fusible switch disconnect modules; wherein the configurable branch enclosure cover includes a frame and at least one column of contiguous first removable portions and second removable portions, each of the first and second removable portions being arranged in adjacent mutual pairs arranged as rows in the at least one column; wherein in each of the adjacent mutual pairs, the first removable portion corresponds in size to a first outer dimension of the first switch housing, whereby when the first removable portion is removed from the frame in the each of the adjacent mutual pairs, an opening is defined in the configurable branch enclosure cover accommodating the first outer dimension; and wherein in the each of the adjacent mutual pairs, the second removable portion in combination with a the first removable portion corresponds in size to a second outer dimension of the second switch housing, whereby when the second removable portion and the first removable portion in the each of the adjacent mutual pairs are removed from the frame, a collective opening is defined in the configurable branch enclosure cover accommodating the second outer dimension.
