AHHH....but while we still have NOT built a perfect mouse trap..we are getting darn close. There (at least in my mind) is a difference. The intent of the AFCI was not to solve against every known condition, only to protect against conditions we can aid to prevent with current technology. All technology has to crawl before it can walk and so while they don't handle 100% of the expressed concerns...we can at least mark the ones off the list that we can help prevent.
But I kinda think we all agree with that. Some just wish (or feel they were mislead) that AFCI's are the means to end all.....they are just another line of defense against potential loss of life and property.
To me this is like installing a red light at an intersection that the electronics to make the red light change has not been developed yet, an extra cost for the tax payers with no visible safety to perform, very against the laws of our country and should have never made it into law as when the NEC is adopted it is law!
Indiana took the stance that if it doesn't do what it says it does then it can not be enforced, and Indiana has deleted 210.12 in all our adopting of the NEC ever since the NEC has required AFCI's
Like Don says the GFP portion of the AFCI is the only part of it that gave us any extra protection in the event of a parallel arc that would migrate to a hot to ground fault, without this I see no protection against an arc to prevent a fire and don't see a way to detect between a good arc and a bad arc since they both would look the same to the arc detection circuit, then only way to different the two would be to gate the arc since a good arc would only last a few cycles so that when an arc happened the detector would ignore it until a couple cycles then if it is still there disrupt the circuit, this way a good arc would be ignored like the arc of a switch turning on or off on an inductive load.
