Universal electrical circuit breaker locking device
First Claim
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.

Abstract
A universal breaker lock device for a switch handle includes a channel adapted to accommodate the switch handle. 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. The channel includes a width defined by a distance measured between the first and second side walls. A lever arm extends from the base wall a distance greater than the width of the channel. A cover, with two apertures, is disposed on the lever arm, to prevent engagement with a fastener. A lock may be disposed through the apertures to prevent removal of the universal breaker lock device while in use.
