A lock out apparatus including a plug having an electrical line extending therefrom and a generally tubular nose portion, a tubular body having an interior passageway removably receiving the nose portion of the plug therein, and a set screw extending through a wall of the tubular body so as to be rotatably movable between a first position exerting a compressive force against the nose portion and a second position releasing the nose portion. An arm is pivotally connected to the set screw and is movable between a first position preventing rotation of the set screw and a second position allowing rotational movement. A post is affixed to the tubular body and includes a slot which is suitable for receiving the arm in the first position. A lock can extend through an aperture of the arm and through holes in the post so as to fix the arm within the slot of the post.
