Universal electrical circuit breaker locking device

1. A universal breaker lock device for a switch handle that projects through an aperture in a switch housing, the universal breaker lock device comprising:

a. a collar member forming a channel therethrough and adapted to engage the switch handle;

b. a blocking member extending from the collar member and configured to contact the switch housing external to the aperture when the collar member engages the switch handle; and

c. a cover member immovably attached to the blocking member, with at least one aperture disposed therethrough.

2. The universal breaker lock device of claim 1 , wherein a surface of the blocking member is substantially parallel to the switch housing external to the aperture when the collar member engages the switch handle.

3. The universal breaker lock device of claim 1 , wherein the switch handle extends entirely through the channel of the collar member when the collar member engages the switch handle.

4. The universal breaker lock device of claim 1 , wherein the blocking member has a long dimension greater than the greatest dimension measured transversely across the channel between opposite surfaces thereof.

5. The universal breaker lock device of claim 1 , wherein the blocking member has a generally rectangular shape.

6. The universal breaker lock device of claim 1 , wherein the channel is defined by a base wall, a side wall that extends generally perpendicularly from the base wall, and a top wall that extends generally perpendicularly from a distal end of the side wall, such that the ends of the top and base walls opposite the side wall have an open gap therebetween.

7. The universal breaker lock device of claim 1 , wherein the blocking member has a short dimension less than the greatest dimension measured transversely across the channel between opposite interior surfaces thereof.

8. The universal breaker lock device of claim 1 , wherein the cover member is adapted to receive a lock member disposed through the at least one aperture, such that insertion of the lock member through the at least one aperture prevents removal of the device from the switch handle, when the collar member is engaged with the switch handle.

9. A universal breaker lock device for a switch handle comprising:

a. a channel adapted to accommodate the switch handle and having first and second planar ends, wherein the channel comprises a base wall, a side wall that extends generally perpendicularly from the base wall, and a top wall that extends generally perpendicularly from a distal end of the side wall, such that the ends of the top and base walls opposite the side wall have an open gap therebetween;

b. a lever arm extending from the channel a distance greater than the greatest dimension measured transversely across the channel; and

c. a cover member immovably attached to the lever arm, with at least one aperture disposed therethrough.

10. The universal breaker lock device of claim 9 , wherein the cover member is adapted to receive a lock member disposed through the at least one aperture, such that engaging the lock member with the cover member prevents removal of the device from the switch handle, when the channel is engaged with the switch handle.

11. The universal breaker lock device of claim 9 , wherein the universal breaker lock device is formed from a single continuous piece of material selected from the group consisting of steel, stainless steel, copper, aluminum alloy, polyethylene, polyvinyl chloride, and polypropylene.

12. A universal breaker lock device for a switch handle, comprising:

a. a channel adapted to accommodate the switch handle, wherein the channel includes a base wall, first and second side walls that extend generally perpendicularly from the base wall, and first and second feet that extend toward one another from distal ends of the first and second side walls, wherein the channel includes a width defined by a distance measured between the first and second side walls, wherein the first and second feet are not connected and define a gap therebetween;

b. a lever arm that extends from the base wall a distance greater than the width of the channel; and

c. a cover member attached to the lever arm, with at least one aperture disposed therethrough.

13. The universal breaker lock device of claim 12 , wherein first and second ends of the channel are generally planar.

14. The universal breaker lock device of claim 12 , wherein a surface of the lever arm extends from the base wall substantially parallel to the first end of the channel.

15. The universal breaker lock device of claim 12 further comprising a threaded aperture disposed through the base wall.

16. The universal breaker lock device of claim 15 further comprising a set screw threadably engaged within the threaded aperture.

17. The universal breaker lock device of claim 16 , further comprising a lock member insertable through the at least one aperture disposed through the cover member.

18. The universal breaker lock device of claim 17 , wherein the insertion of the lock member through the at least one aperture prevents adjustment of the set screw.

19. The universal breaker lock device of claim 12 , wherein the cover member is adapted to receive a lock member disposed through the at least one aperture.

20. The universal breaker lock device of claim 19 , wherein engaging the lock member with the cover member prevents removal of the device from the switch handle, when the channel is engaged with the switch handle.
