Abstract
A locking assembly is for a circuit breaker. The circuit breaker includes a housing enclosing separable contacts and an operating mechanism. The housing has an elevated portion with an opening. An operating handle, which operates to open and close the separable contacts, protrudes from the opening and moves between “on” and “off” circuit breaker positions. The locking assembly includes first and second locking elements pivotally connected to the operating handle and structured to engage the elevated portion of the circuit breaker housing, in order to restrain movement of the operating handle from either the “on” or “off” position when the shackle of a lock is inserted through shackle-receiving apertures of the first and second locking elements.
