Seriously????
Now, don't misunderstand me. I've a long history here in struggling with the AFCI debacle as forced upon the electricians installing them. I am not changing my opinion in this post.
But!
This single non-GFP solution, to the "Grand Concept" of AFCI as foisted upon us, I find to be the most efficacious, in terms of customer relations after the install, in terms of flexibility of use with multiwire branch circuits, and, MOST IMPORTANTLY, the paradigm most likely to result in the product liability lawsuit that will least ambiguously lead to the whole AFCI mess being forced to clean up its act.
