ADJUSTABLE DOOR ASSEMBLY

One or more apparatuses are provided for forming a seal between a circuit breaker (108) and an enclosure (102). A adjustable door assembly (200) comprises an inner floating frame assembly (214) positioned according to a floating configuration between a first external flange (205) and a second external flange (201) that connect to an enclosure door (104) of an enclosure (102) housing a circuit breaker (108). The inner floating frame assembly (214) comprises an inner floating frame (204) and an inner floating box frame (202). An adjustable coupling is used to apply a force, between the inner floating frame (204) and the inner floating frame box (202), to the inner floating box frame (202) towards a front side (110) of the circuit breaker (108) to form a seal between the front side of the circuit breaker (108) and the enclosure door (104). The seal may provide a barrier for mitigating arc flash, hazardous gases, material, and/or explosive force from escaping from a backside (108a) of the circuit breaker (108).
