Lawrence Brown, CMP-2 member, submitted several proposals (or maybe, the same proposal several times) to get rid of the requirement. I would also like to quote his response to his negative vote to the comment:
BROWN, L.: The Panel’s Action to not require AFCI protection only for the receptacles that typically require GFCI protection is backtracking from the Panel’s Actions and Statements shown in the Report on Proposals (ROP). If they felt the entire house should be protected what relevant fire data changed their minds? Please read NAHB’s Comment 2-79. Calling this a “limited approach to the expansion of AFCI” still results in no cost-benefit for society, it just needlessly increases the costs of housing. No jurisdiction should burden its citizens with this unneeded expense.
There was never any fire study or costbenefit study to support installing these devices only for bedrooms in the 1999 NEC. Since then NO data or study has ever been assembled to support the expansion to the whole house. The fact still remains that home buyers in the U. S. will spend approximately 2 BILLION, 130 MILLION, 230 THOUSAND, and 956 DOLLARS per year to cover losses of only $17,720,000. That is a ratio of 119 times the money spent relative to the monetary loss of $17,720,000.
And, that is if the devices work 100 percent of the time. If you break that down by each state, that lack of a cost-benefit becomes apparently clear. All jurisdictions that contemplate adopting the 2008 NEC, especially those jurisdiction that by law must show a cost-benefit in the adoption, are encouraged to look closely at this cost-benefit fact and not adopt the 2008 NEC until all provisions requiring AFCIs is stricken (Section 210.12).
