Zusammenfassung:	A retainer plate is pivotally mounted on a panelboard cabinet door lock housing, which carries a latch for locking the door. A detent on the plate engages in a rabbet opening to enable limited opening movement of the door in response to the pressure developed by arc gases generated by fault currents passing through a tripped circuit breaker in the panelboard cabinet. For ordinary opening movement, the lock latch is manually operated to pivot the retainer plate and disengage the detent from the rabbet opening.
