I do not have any experience with Eaton AFCI breakers and nuisance tripping.
The theory of an AFCI seems sound to me. Here's a funny story.
When I go into thrift shops, I buy any bathroom appliance (curling iron, hair dryer, etc) that is priced at a buck and has the cheap GFCI type power cord. I solder these things to the receptacle end of my old extension cords just because I can. I have a few in use IN the house on some temporary lighting in my workshop.
They are NOT immune to 'nuisance tripping', and no sooner do I exceed 10 watts, they do all sorts of strange thigs. They chatter, they pop and they make the 60 cycle oh-no sound like when a loudspeaker is hooked directly to the mains. Fun times.
Not trying to hi-jack your thread, but thought maybe you'd enjoy that tale.
