Temporary restriction of access to circuit breakers

摘要

A circuit breaker can actuate to a closed condition and to an open condition. An assembly for the circuit breaker can include an obstacle that can be positioned to obstruct one form of actuation while permitting another form of actuation. The obstacle can be moved from the obstructing position to allow multiple forms of actuation. The obstacle may permit manual actuation of the circuit to an open state in any position.

主权项

1. A circuit breaker assembly comprising:
a circuit breaker having a lever movable among a closed position, an open position, and a reset position, the lever configured for movement from the open position to the closed position via the reset position and for movement from the closed position directly to the open position; a housing that frames the circuit breaker; a cover comprising:
a base installed on the housing, the base comprising (a) a first bar attached to the housing and comprising a hinge; and (b) a second bar attached to the housing and comprising a first locking feature; andan arm comprising a first end and a second end, the first end pivotally coupled with the first bar via the hinge such that the arm is pivotable between (a) an obstructing position in which the arm obstructs movement of the lever of the circuit breaker to the reset position and permits movement of the lever of the circuit breaker from the closed position to the open position, and (b) an accessible position in which the arm permits movement of the lever of the circuit breaker to the reset position; and a second locking feature that is (a) engagable with the first locking feature to secure the second end of the arm with the second bar so that the arm is locked in the obstructing position, and (b) disengagable from the first locking feature to release the second end of the arm from the second bar so as to permit movement of the arm to the accessible position.
