Al, i've investigated afci's ,along with sorts that have a lot more grey matter than i do for decades.
I've also bench tested most brands myself, that and a dime might get me a cuppa joe...
What you're asking for is
clarity and transparency from a manufacturer , so have many ,including a number of litigant entities, the original nema afci team leader, nfpa EE's, as well as this forum's host
There is no formal 110.3B complaint or explanation process, and i doubt there is ever going to be one, despite a world of editorials and tech documents alluding to whatever bias they hail from
So , i'll give you MY take ,
AFCI's, GFCI, RCD, LCDI's, etc have
one common key component
this>>>>
No matter how much electronic wizardry one lumps onto it, a toroid can ONLY sense what a toroid can sense
a 6, 30, or whatever ma trip is merely whatever resistive element is placed within it's capabilities
some manufacturers will differ
that's my story, and i'm stickin' to it
thx
