AFCI protection is required for 15- and 20-ampere, 120-volt branch circuits providing outlets located in which areas?

Hallways
Guest rooms
Bathrooms
Garages

The correct answer is: Guest rooms

AFCI (Arc Fault Circuit Interrupter) protection is specifically required in areas where there is a higher risk of electrical fires caused by arc faults, which can occur when there are loose or damaged wires. In the case of guest rooms, these areas can often have multiple plug-in devices that create potential arc faults, such as lamps, chargers, and other electronic devices. The requirement for AFCI protection aims to enhance safety in areas where people sleep, as electrical fires pose a significant risk during the night when individuals may not be fully aware of potential hazards. Guest rooms, being a type of habitable space where furnishings and electronic items are frequently used, are therefore among the specific areas designated for AFCI protection to minimize fire risks. While hallways, bathrooms, and garages also have specific electrical code requirements, they do not require AFCI protection as guest rooms do. This reflects a targeted approach to address the unique risks associated with habitable sleeping spaces.
