Abstract
A manual disconnect includes a housing and a base attached to the housing by a fastener. The base includes primary terminals. The manual disconnect also includes a plug assembly that includes fuse terminals and a bolt cover. The plug assembly is movable relative to the base between a disconnected position wherein the fuse terminals are not engaged with respective primary terminals, and a primary circuit engaged position, wherein the fuse terminals are engaged with respective primary terminals. When the plug assembly is in the primary circuit engaged position the bolt cover is positioned to prevent the fastener from being removed from the housing. A handle or cover part of the plug assembly is then rotated to a locked position with respect to the base. Then, the plug assembly can be moved further in the insertion direction to close an interlock circuit, allowing current to flow in the primary circuit.
