Inor, I could write ten paragraphs on arc fault breakers, but I will shorten it down to this-
Keep the “regular” breakers that your electrician removes. You are going to want them. After you pass final inspection, change them back, and throw out the arc fault breakers. They are such useless, annoying, and unreliable pieces of junk that the National Electric Code eliminated their required use after only three years of having the requirement in the Code. I can only assume that you have a local building code that maintains their requirement in new construction.
The only reason this new, untested, and crappy technology made it into the National Electric Code to begin with was the fact that the inventor/ patent holder was on a Code-making committee. Even then, it was eliminated a short three years later.
