Abstract
A fused mechanical interlock in an electrical switching device precludes a fuse access door from being open when the switching device is energized. The fused mechanical interlock optionally cooperates with a plug interlock mechanism which prevents the switching device from being energized unless a plug is properly inserted in a receptacle.
