Abstract
A single pole circuit breaker having a narrow housing is provided with a blocking device which prevents inadvertent manual operation of the circuit breaker. The blocking device is a single piece unit constructed of relatively stiff resilient metal formed with a generally flat main section having rearwardly extending short legs along opposite sides thereof. The legs are received within undercut portions of housing recesses positioned along opposite sides of the housing opening through which the handle extends. The blocking device is selectively positionable so as to prevent operation of the handle to either the ON or OFF position and the main section is provided with a window through which ON-OFF indicia, indicating handle position, is viewable.
