Abstract
An apparatus for locking the switch handle of a circuit breaker in the ON or OFF position. The apparatus includes a blocking member mountable on the handle with two screws, a pivoting member pivotable about the screws and a lock for locking the blocking member to the pivoting member. When the blocking member and the pivoting member are locked together, the blocking member is maintained in a position such that it interferes with the circuit breaker housing and prevents the handle from being moved.
