Without the backing of hundreds of thousands of dollars for research, the CMP will never accept proposals to limit the use of AFCIs. They are here to stay. The best I could hope for is that the UL standard for AFCIs be revised to require a GFP function in all AFCIs as it appears to me that the GFP function it the most common trip.
