Ceiling fans tripping arc fault breakers
The harmonics generated by variable speed motor controllers confuse AFCI’s and cause them to trip. This is a known defect also heavily loaded lighting circuits with modern ballast and light dimmers are known to cause tripping. They have become slightly better but still have this issue. My state allows the AFCI to be omitted for circuits with known issues. Check with your AHJ. (Authority having jurisdiction), a call to the local inspectors office will usually get a reply within a day sometimes 2 during the week.
