Please note that even the NFPA has recognized that the currently available branch circuit/feeder AFCIs are not very effective at preventing electrical fires. A proposal has been accepted for the 2005 code that will require the use of "combination type" AFCIs. At this time only one manufacturer has a combination type AFCI and because of this the rule requiring these devices will not take effect until Jan. 1, 2008. Until that time the installation of the less effective type of AFCI will still be permitted.
