- Yoke member 28 covers the second aperture 25 of the base member 22.
- First aperture 24 is not covered. Therefore, the yoke member 28 covers access to the mechanical fasteners used to fasten the base member 22 to the circuit breaker cover 12.
- the locking device 20 Figure 1
- tampering with the locking device 20 is prevented.
- a slider member 32 includes a first leg 36, second leg 38 and a base portion 40.
- Base portion 40 has three apertures 46 generally lined up along an edge of the base portion 40.
- Second leg 38 has two padlock apertures 34.
- First leg 36 and second leg 38 extend generally perpendicularly outward from the base portion 40 and in the same general direction.
- First leg 36 includes ari opening, preferably elongated, 70. Opening 70 employs additional padlocks (not shown).
- An arm 64 extends from first leg 36 of slider member 32 and includes an aperture 66. Arm 64 is generally bent towards the first leg 36.
- slider member 32 is arranged to overlie said yoke member 28 for slidable movement. Further, slider member 32 covers access to the mechanical fasteners inserted through apertures 42 of the yoke member
- Slot 84 provides access to mechanical fasteners inserted through apertures 42 of yoke member 28 when locking device 20 is in the unlocked condition.
- Handle block 30 further includes a first end 76 and a second end 78.
- Second end 78 includes an L-shaped bend. Second end 78 ensures that the locking device 20 is locked only in the OFF position or the ON position by obstructing (the slider 32 connected to handle block 30 cannot be slid on yoke 28 unless the handle 14 is in the intended position of locking since it is obstructed by the projection second leg 78 or first end 76. E.g. when the lock is configured for locking in OFF position and attempted to be used for locking in the ON position) handle 14.
- One aperture 71 of handle block 30 selectively aligns with one aperture 46 of slider member 32.
- Mechanical fasteners are inserted through apertures 72 and extend through corresponding selected aligned apertures 46 of slider member 32.
- Handle block 30 is positioned such that first end 76 abuts handle 14 (Figure 1) when handle 14 is in the OFF position and second end 78 abuts handle 14 when handle 14 is in the ON position.
- first end 76 abuts handle 14 ( Figure 1) when handle 14 is in the OFF position and second end 78 abuts handle 14 when handle 14 is in the ON position.
- a cam link 58 is shown with an aperture 60 and a first end 62.
- Cam link 58 is part of the locking device 20 ( Figure 1). Referring to Figure 1
- first end 62 of cam link 58 is arranged to for insertion into aperture

- the first leg 36 and base portion 30 of slider member 32 are positioned proximate to the yoke member 28 and in slidably contact with yoke member 28.
- a nut 88, or other similar mechanical fastener, holds the first arm 62 of cam link 58 in aperture 66.
- a lock 48 preferably a figure lock such as sold under the trade name Ronis 1104 and Profalux B24, is used to prevent the slidable motion of the slider member 32 and handle block 30.
- Lock 48 is inserted through aperture 50 of yoke member 28 and extends through aperture 60 of cam link 58.
- First end 62 of cam link 58 is configured to fit into aperture 66 to prevent movement of the slider member 32 when the lock 48 is installed. Further, the cam link 58 permits lock 48 to be mounted onto the locking device 20. Therefore, once the lock 48 is installed, the slider member 32 is prevented from movement. The handle block 30 connected to the slider member is also prevented from movement.
- the handle block 30 is positioned to abut either the first end 76 or the second end 78 depending on whether it is desired to lock the circuit breaker 10 (Figure 1) in either the OFF position (shown in Figure 1) or the ON position (shown in Figure 2). Since the handle block 30 is locked in the selected position relative to the handle 14, the handle 14 will be locked in the desired OFF or ON position.
- a padlock 68 may be used, preferably of 5-8 mm in diameter. Padlock 68 is positioned through padlock apertures 55 of the yoke member 28 that are aligned with corresponding padlock apertures 34 of the second leg 38 of slider member 32.
- Padlock apertures 55 and padlock apertures 34 are sufficiently spaced apart from one another such that one to three padlocks 68 may be inserted through each respective padlock aperture 55 and corresponding padlock aperture 34.
- padlock 68 similar to lock 48, prevents the slider member 32 and the handle block 30 from slidable motion when the operating handle 14 is locked in the desired ON or OFF position.
- An authorized user may remove the padlocks 68 or unlock the locks 48 as desired and reconfigure the locking device 20 to switch the circuit breaker 10 from the OFF position to the ON position or visa versa.
- Locks 48 are unlocked by the authorized user through insertion of a key that disengages the cam link 58 from aperture 66 of arm 64 of slider member 32.
- the slider member 32 is slid on the yoke member 28 in order to move the handle block 30 such that handle 14 is free to switch the circuit breaker 10 ON or OFF.
- the locking device 20 is then repositioned.
- the locking device may be re-assembled only if the user wishes to change the mode of locking (from ON to OFF or from OFF to ON).
- the "push to trip" button 70 located on circuit breaker cover 12 is preferably covered by the second arm 74 of slider member
- the locking device 20 is versatile so that it may be used for locking the handle 14 of the circuit breaker 10 in either the ON position or the OFF position.
- the locking device 20 is mounted directly on the circuit breaker and authorized users can be readily unlock the selected locks and convert from the OFF position to the ON position or visa versa. Further, all mechanical fasteners holding the locking device 20 to the circuit breaker cover 12 are covered thereby preventing unauthorized tampering with the locking device 20.
- Another feature of the present invention is the built-in safety provision within the base member to avoid accidental or purposeful tripping of the circuit breaker 10 when it is locked in the ON position.
