Sparky,
Thanks for the reference. I noted it earlier when you provided it in another thread, printed it out and went over it. That too whets my appetite. ZLAN's site contains the most tech I've seen yet, but it is just to the side of clear for me. . .I may be thick, but it seems that the core of an AFCI is waveform recognition, either current, voltage or both. What I don't understand is the implementation of the hardware solution.
Brendan,
Maybe you have access to CH's waveform analysis? What are the identifiable characteristics of the class of faults the AFCI triggers on, and how does the (presumed) logic in the trigger discriminate between arc waveforms of varied "flavors". Am I even asking the right question here? Or is the answer to the question a trade secret that each manufacturer is keeping under wraps for the time being?
Respectfully,
Al
