Somehow I thought I saw in the description that it could be used to calculate available fault current for arc flash purposes as well as 110.24 required labeling. Perhaps I just misread it. I see a lot of references to "the qualified individual." Perhaps this is just for liability avoidance, but the questions asked were not below the level of questions other experienced electrical workers may ask, if they even think enough to.
Then, there's the comment that certainly, someone could conclude something, as anything is possible. My suggestion wasn't in ignorance. Even the official 2014 analysis of changes says that the marking requirement is there to help field installers determine required interrupting ratings of equipment.
Are you saying here, that is is not a requirement of the NEC, that only a professional engineer is allowed to, say for example decide to use a sub panel that has devices with lower interrupting ratings than that of the main breaker? If this is proven to be the case, it is a fact that many knowledgeable people have thought otherwise. it certainly is not one of those many things that could be concluded, just because any conclusion is possible.
