Abstract: One or more apparatuses are provided for forming a seal between a circuit breaker and an enclosure. An adjustable door assembly includes an inner floating frame assembly positioned according to a floating configuration between a first external flange and a second external flange that connect to an enclosure door of an enclosure housing a circuit breaker. The inner floating frame assembly includes an inner floating frame and an inner floating box frame. An adjustable coupling is used to apply a force, between the inner floating frame and the inner floating frame box, to the inner floating box frame towards a front side of the circuit breaker to form a seal between the front side of the circuit breaker and the enclosure door. The seal may provide a barrier for mitigating arc flash, hazardous gases, material, and/or explosive force from escaping from a backside of the circuit breaker.
