It appears that the problem with the Eaton AFCI's is going to continue for a long time and may never be resolved. The reason I say this is that the troublesome AFCI's are still to this day being manufactured and installed in neighborhoods all across the United States.
I just moments ago (8:37 AM Today) got off the phone with Joe Fello and he affirmed that Eaton is still manufacturing and electrical contractors are installing these troublesome breakers all over the US. They are only using the "HAM" breakers and replacing the faulty breakers on an "as need" basis. In my opinion this is making it more difficult to correct the problem if the manufacturer is still producing the product that is causing it and electrical contractors are still installing them. In my neighborhood the electrical contractor is installing them in new homes at the rate of two homes per week.
It would really help if Eaton would make a public statement regarding the issue with their tripping AFCI's and how they intend to resolve the issue presently and in the future. Currently the only thing that eludes to the problem is what was published by the League in November of 2013. Absolutely nothing publicly from Eaton.
The ARRL has told us that the problem is self correcting with Eaton and needs no more publicity or staff time devoted to this problem. I disagree with their position on this. I pity the poor ham 10 years down the road that moves into a neighborhood loaded with these breakers and tries to get an HF station on the air.
