I have observed most 200 amp CSED's now state "Use 10-100A and 150-200A Branch Breakers Only" in the technical specifications. I am looking to replace my existing meter and main panel. QC2442M200C would be the ideal size, however it seems to exclude support for 125A breakers. QC3040M200S is larger than I need, however it's specifications include the usage of a 125A breaker. I spoke with an inspector within my AHJ, and he indicated that I shouldn't have any problems with a 125A breaker, however I am cautious as most CSED's seem to exclude 125A breakers.
Is there a reason 125A is excluded, or any amending documentation?
