AIC requirements are requested/required by most AHJ's.
AIC formulas are to involved to include here, but try the Bussman website. They should have the info either as downloadable, or you could request the booklet.
It's math, not to deep, and their method is acceptable.
AIC ratings of various CB's are available from the mfg; there is a lot of useful info within most catalogs, trip curves, etc.
