Abstract
A terminal assembly may be provided which utilizes an electrically insulating cover to electrically isolate upper portions of screw terminals. The electrically insulating cover could be made from plastic, rubber or some other electrical insulator, and could be mounted on a frame configured to engage with a frame supporting the screw terminals. While lower portions of the screw terminals may continue to electrically connect with electrical connectors for receiving load stab conductors (from a unit), upper portions of the screw terminals may be electrically isolated to protect from short-circuit, and/or shock, such as while a door or access panel of a wire-way is removed. The electrically insulating covers may also include cable glands for circumferentially surrounding wires leading to the screw terminals. A retainer clip may also be used to securely hold the electrically insulating covers to the frame supporting the screw terminals.
