I am reminded that they NEC came about because of insurance companies. AFCI has been a big problem in some applications. In the artical they stated that there has not been any substantiated claim of AFCI not working with equipment or appliances. I can prove them wrong. I have had many items that will not work on AFCI circuits. Vaccums, ceiling fans, audio systems with high current amps, water bed heaters, hair dryers. to name a few. These are items I have personally witnessed and have testes. I install a lot of lighting control systems, most panels have a come neutral bus. You can not combine loads from different brach circuits when using AFCI. Also ceiling fans are manufactured with a common neuttral for fan motor and light. I don"t think AFCI are bad. They just don"t need to be installed on every circuit.Such as dedicated spaces for appliances, entertainment centers. Lighting that is hard wired or smoke detectors. These circuits could be easily seperated from receptical outlets for general use. We need some common sense here. I know the real driving factor is not saftey. It is profit. And, there will be a lot of it if those making the products are pushing for code changes.
