Panelboard for fusible switching disconnect devices

A panelboard, comprising:

• a mounting enclosure having a width of at most 20 inches;
• and
• a chassis coupled to the mounting enclosure and configured to receive at least one fusible switch disconnect module, the at least one fusible switch disconnect module comprising:
• a disconnect housing adapted to receive at least one rectangular fuse module therein, the at least one rectangular fuse module including a rectangular housing and a pair of plug-in terminal blades extending from the rectangular housing, the at least one rectangular fuse module configured to be installed to and removed from the disconnect housing without utilizing screw fasteners,
• a line side terminal and a load side terminal communicating with the pair of plug-in terminal blades of the at least one rectangular fuse module when the at least one rectangular fuse module is installed, and
• switchable contacts provided between one of the line side terminal and the load side terminal of the disconnect housing and the fuse, the switchable contacts comprising at least one stationary contact and at least one movable contact being selectively positionable along a linear axis with respect to the stationary contact between an open position and a closed position to connect or disconnect an electrical connection through the at least one rectangular fuse module.
