This is the first report that I've heard of this. When did you first call Eaton? Did you leave a message or try to call again? What is the current status of you complaint? Thanks.

Here is an update on this situation as of today for 2016. We have received a total of five AFCI complaints here at the ARRL since January.

Here is a brief run down on each:

1) Ham was referred to Eaton in February. No further issues were reported.
2) Ham was referred to Eaton in February. No further issues were reported.
3) Complaint involved a non-Eaton breaker. I believe the ham added chokes to mitigate the problem.
4) Ham was referred to Eaton in April. No further issues were reported.
5) Ham was referred to Eaton in June. No further issues were reported.

In summary, each of the four Eaton breaker complaints that we received this year were referred to Eaton for free replacements. After that referral, none of them has reported any further issues. Please also be assured that we are still monitoring the situation.

Thanks,

U-Verse customers probably number in the millions by now. Statistically speaking, we've had a surprisingly small number of complaints given from them. Offhand I don't recall any in the last few months and most of the older complaints were resolved.

Assuming that you are operating at HF, ferrite beads are unlikely to fix the problem. I might suggest using ferrite toroids on the speaker leads, especially if this problem can occur even when the stereo is not on. Install the cores as close to the amplifier as practical. A good mix might be type 31 ferrite, but if you can't get it, try type 43. I'd start by wrapping about ten turns or so around the toroid to see what happens. You may also need to add similar chokes and an ac line filter to the power cord of the stereo. I would not think that this problem is directly related to the tripping AFCIs.
