摘要:
A panel board retrofit kit, and method of selecting a panelboard retrofit kit, for replacing a panel board having a switching device in an enclosure is disclosed. The panel board retrofit kit has a first dead front plate having a first aperture, and a second dead front plate having a second aperture. The second aperture of the second panel board dead front plate is configurable to overlap at least a portion of said first aperture of said first dead front plate. The disclosed panelboard retrofit kit and method enable replacement of an installed panel board without removing or replacing the panel board enclosure.
