Circuit breaker block out

A block out device for use with a circuit breaker having a body presented to a user, and having an actuating element extending through the body and thereby accessible for actuation by the user, and movable between opposite positions, said block out device comprising,

• a one-piece member having a pair of opposed main parts connected together by hinge means having an axis, said pair of main parts having swinging ends movable toward each other to a locking position wherein they are substantially in interengagement, and away from each other to a non-locking position,
• the main parts, when the device is applied to a circuit breaker and the main parts are in locking position, are adapted to engage said actuating element and prevent movement of said element between said opposite positions,
• the main parts having cooperating apertures located at their swinging ends adapted to receive a locking element of predetermined dimensions, said cooperating apertures having a common axis when in said locking position, such that said apertures are in alignment and said axis is perpendicular to an axis extending parallel with the axis of the hinge means, and
• a first of the main parts including a latching element extending through the aperture of a second of the main parts and engaging the second main part in a latching position, for holding the main parts in locking position, said second main part having a key way located in a surface of the aperture therein, and the latching element being positioned within said key way when in said latching position,
• the apertures being of such size that when the locking element is in said apertures, the latching element is effectively engaged by the locking element and held in said key way and thereby held in latching position,
• the block out device having locking connection with the actuating element and is operable for locking the actuating element, only by locking engagement therewith.
