Branch Circuits & FeedersPregunta 19 de 120
Arc-fault circuit-interrupter protection is required for 120-volt, single-phase, 15- and 20-ampere branch circuits supplying outlets in which dwelling unit areas?
a.Kitchens, laundry areas, bedrooms and most other habitable rooms
b.Bedrooms only
c.Unfinished basements and garages only
d.Bathrooms and outdoor areas only
Explicación
The AFCI requirement now reaches nearly every habitable area of a dwelling, including kitchens and laundry areas, not just bedrooms as in older code cycles. Bathrooms, garages and unfinished basements are the spaces typically addressed by GFCI rules instead, so limiting AFCI to those areas reverses the two protection schemes.
