I do note believe that Arc fault breakers are anything but a waste. After fifty or so years of doing electrical repairs I just don't see a need nor do I think arcs are causing fires or problems that need addressing to the level that these beasts have changed our industry. I suppose that manufacturers will show some studies but I don't buy it. I do, however believe in GFIs. GFICs make sense and can save a life or prevent a fire. They are a nuisance though and I suspect that because AFCIs are also GFICs that the problem is reset after reset. Oh well, I guess we will have to live with it. Jack Miller
