  • Patent number: 4491898
    Abstract: A fuse mounting arrangement for a pad mounted underground electrical power distribution systems includes at least one fuse panel which is slideably mounted by means of slide bearing assemblies in a housing enclosure. The fuse panel is removably mounted on the slide bearing mounting channel by means of cooperating tabs, slots and C-shaped loops or eyes. Should a fuse panel or its associated power fuse require replacement, safety interlock means including fixed locking pins and a cooperating U-shaped handle having hooked portions for engaging the locking pins are provided. It is imperative that the fuse panel and its fuse be electrically isolated prior to removal or withdrawal of the same from the housing enclosure. Therefore, the fuse elbow connector and its associated line conductor are disposed in front of the handle which is pivotably mounted upon the fuse panel between a locking position and a release position.
