Correct answer to question 4048
- D: No, an exception permits omitting AFCI for this circuit
Explanation
AFCI protection is not required for an individual branch circuit that supplies a fire alarm system when it is run in a metal raceway, metal-clad cable or a similar wiring method as described in Article 760 (see 760.41(B) and 760.121(B)). In the 2026 edition this appears as Exception No. 1 to 210.12(B). The exception avoids nuisance tripping that could disable the alarm.
