As a principal voting member of a different Panel, I can state categorically that there are many special interests, driven by profit, that exist on the NEC Panels. Dr. Ingel's conservative estimate of $1 billion in increased cost to the consumer by requiring combination-type AFCI devices as opposed to branch circuit AFCI devices (which are not allowed to be installed according to the current Code) shows the magnitude of the profit we're talking about. A billion here, a billion there - pretty soon you're talking real money. UL - the more I learn about them, the more disappointed I become. Guess what - they're in it for one reason only - and of course, that's THE MONEY.
I sent a proposal to Panel 2 saying to remove the wording "combination type" from the requirements for AFCIs, and provided video evidence to the Panel showing that these devices absolutely will not trip in a series arcing conditon. Rejected. Absolutely amazing. I can't believe that it's all done out of ignorance, as the evidence is so overwhelming.
We need a device that can detect the overheated connections that do occur in the real world, and prevent our houses from burning down from the resulting fires.
