I am not an expert on this issue and my opinion is by no means the last word on the subject.
AFCI's trip for various reasons. They are designed to trip when an arc is detected or the amperage for that circuit is exceeded. The problem is that there are some electrical appliances that are designed to have an arc, like corded drills, some vacuum cleaners, etc, etc.
So....when an AFCI trips, the question is this.....Is the AFCI defective, oversensitive, etc, or is it correctly doing it's intended job. If the circuit is a 15 amp circuit, and you have a huge TV, sound system, a bunch of lamps, etc on the circuit, then plug in a powerful 12 amp vacuum cleaner, and the AFCI trips, you have probably exceeded the amperage.
While 15 amp receptacle circuits pass code, I personally prefer all of my receptacles wired with 20 amp circuits, but that is not required.
Furthermore, some AFCI's can trip from some refrigerators, plasma TV's etc. Sometimes the Electrician's will add a magnet type device to the conductors in the panelbox, or add a coil of additional conductors to that circuit to dissipate the problem, or change the electrical cord, etc, in the back of the refrigerator to solve this. Whirlpool recently has been covering the warranty cost of this on homes less than one year old.
To complicate the issue, one can have a Ham Radio operator a block away trip your AFCI breakers. That Ham Radio operator is doing nothing wrong, and his equipment is totally compliant to all laws and codes. He has every right to be a Ham Radio operator, just as much as you have the right to play golf. He is doing nothing wrong. You can own your home for say 5 years, no problems, then suddenly you have this problem due to a new neighbor or new hobby.
The law states that the manufacturers of the AFCI's have the obligation to make their product work with all existing electrical and radio frequencies, etc. The onus is on them. Not your neighbor. Sadly, this does not help you at all or solve your problem.
There are different generations of AFCI's, and the newer ones are less problematic. They are costly. A regular circuit breaker can cost less than $5.00, but AFCI's can be between $50-$80 a piece. Plus installation.
So, in short, this problem has a number of different causes, and some of the causes are the normal intended function of the AFCI(s). One size does NOT fit all.
This is NOT just a problem here in The Villages....it is a well known issue that should work itself out as the newer generations of AFCI's become more common.
When I do a warranty inspection I ask the homeowners if they have had any issues of this nature and make sure it get into the report so the Electrician's can take all the needed steps to remedy the issue, whether it be changing the AFCI, or the refrigerator component, etc.
Again, I am NOT an licenced Electrician. I have wired complete houses and as a Home Inspector have a good working knowledge of typical household electrical systems. I post this only as an attempt to clarify the issue somewhat. If you have this type of issue, I suggest contacting a good licensed Electrician to troubleshoot your UNIQUE situation, as your "fix" may be different than your neighbor. Any good Electrician should have a good understanding of this issue. I do know that Terry from Pike's is considered an expert on this issue.
I hope this helps....
