Will the main breaker in a Mini Power Zone series rate w/ the downstream breakers for a higher AIR rating?

Series rating downstream of the Mini Power-Zone (MPZ) package unit substation is unnecessary. The MPZ is a UL listed device and the transformer does not allow peak let through currents higher than the secondary type QO breakers can accommodate. The AIR of the device matches the AIR rating of the primary breaker, which is a type FAL.
