Some yers ago I had a problem with the arc fault detectors tripping when transmitting. After contacting the ARRL to see if they were aware of any problems with these devices, it turned out that some of the new Eaton units were overly susceptible to RF. They put me in touch with Eaton who replaced all of them in my home. This resolved most of those issues.
