The 1999 NEC required arc-fault protection as follows.
210-12. Arc-Fault Circuit-Interrupter Protection
(a) Definition. An arc-fault circuit interrupter is a device intended to provide protection from the effects of arc faults by recognizing characteristics unique to arcing and by functioning to de-energize the circuit when an arc fault is detected.
(b) Dwelling Unit Bedrooms. All branch circuits that supply 125-volt, single-phase, 15- and 20-ampere receptacle outlets installed in dwelling unit bedrooms shall be protected by an arc-fault circuit interrupter(s). This requirement shall become effective January 1, 2002.
In the 2002 NEC, the word "receptacle" was removed,
making it "All branch circuits that supply 125-volt, single-phase, 15- and 20-ampere outlets installed in dwelling unit bedrooms", which now covers ALL OUTLETS on 15 and 20 amp 120 volt circuits. Light fixtures are mounted on "lighting outlets", smoke detectors are mounted on "outlets" for the smoke detector. These are "outlets" and are now to be arc-fault protected.
The change was intentional, not accidental.
