There are many surprises to be found when removing electric panel covers. At this panel, rodents borrowed some fiberglass insulation from under the floor above the basement to make a cozy little nest. It doesn’t take very much space for mice to squeeze into places, but there was more than enough entrance space provided by the missing knock out tabs (those round openings) at the top of the panel.
