OX-30 Abstract Of The Disclosure A plug-in apparatus for use with an electrical busway con- taining a plurality of bus bars includes an enclosure with an electrical accessory disposed therein. A plurality of plug-in jaws are connected to the electrical accessory and extend through a rear wall of the enclosure for engaging the bus bars. An operating handle is mounted outside of the enclosure. An interlock assembly includes an elongated interlock arm movably connected to the enclosure and extending in a generally horizon- tal direction across a plane of the rear wall of the enclosure. The interlock arm is movable relative to the enclosure between an unlocked position and a locked position. A safety link is operably associated with the operating handle and interlock assembly for preventing the operating handle and the interlock assembly from being simultaneously located in their "On" and unlocked positions, respectively. When the interlock arm is moved from its unlocked position to its locked position, the rearward portion thereof pivots upward relative to the enclosure so as to lock the plug-in apparatus to the busway. Further for- ward motion of the interlock arm slides the interlock arm forward without any additional pivotal motion so as to snugly secure the plug-in apparatus to the busway.
