Abstract
A dead front fuse mounting assembly supports the fuse on a hingedly mounted plate which can pivot through a 90.degree. arc to allow access to the fuse. The plate can be latched in a circuit closed position and cannot be released therefrom until a high voltage elbow connector is removed from across a latch operator. Pivotal motion of the plate from the closed circuit position disengages the fuse from a second high voltage contact and releases a shutter to isolate this contact from the remainder of the fuse enclosure. The shutter is opened when the plate pivots back to its closed circuit position.
