I think it is a big mistake for the NEC to require ALL 15 and 20 Amp branch circuits to be AFCI protected.
The number of service calls because of nuisance trips is going to be huge, and costly.
The cost of these breakers is also going to be a lot for home owners and builders to absorb. Certainly the cost will decrease as technology and production costs change. Until then, the increase of the costs for the electrical could be as much as $1000.00, possibly more.
I hope that this proposal fails. Steven Ford
