ABSTRACT:
A lock and method for locking circuit breakers, as well as a tool for making such circuit breaker locks. The circuit breaker lock comprises a U-shaped member with a portion of one of the arms of the U being bent away from the other out of the plane of the U, the bent portion forming a foot. The other of the arms is insertable into a bore which extends through the toggle switch on a circuit breaker. The circuit breaker is locked by placing the foot against a portion of the circuit breaker housing such that the switch cannot be urged from its locked position. The tool used for making such circuit breaker locks has first and second jaws which are movable toward and way from each other. A U-shaped bracket is mounted on the first jaw, which bracket receives the second jaw as it is moved toward the first. The bracket has two spaced supports which receive the second jaw therebetween when it is moved toward the first and project away from the first jaw. A piece of wire can be placed across the tops of the supports and bent into a U shape as the jaws are moved toward each other. Thereafter, one of the arms of the U-shaped portion can be bent to form the foot of the circuit breaker lock.
