Abstract: A detachable protective cover for an electrical terminal block comprising a pivot member top whose sides are pivotally attached by pins to support members connected to the terminal block with fasteners. The pivot member top overlays the block in the cover's closed position, but can be pivoted forward to expose the block in the cover's open position. In a preferred embodiment when the block is mounted horizontally on a distributing frame, the pivot member top can pivot forward and downwardly to an angle from the horizontal so as to preclude interference with a ladder associated with the frame when the ladder is positioned in front of an open cover.
