ARC fault circuit interrupters are required in which room?

• A. Kitchen
• B. Bathroom
• C. Bedroom
• D. Garage

Answer: (C)

Arc fault circuit interrupters protect against dangerous arcing in electrical circuits, which can heat up and start fires. In dwelling units, arc-fault protection is required in living areas where outlets and cords are commonly used and where a hidden arc could go unnoticed while people are nearby or asleep. The bedroom is the primary living space designated for this protection, so installing AFCIs there reduces the risk of an arc-fault fire in a room where people spend a lot of time and may not notice a developing fault right away. Other rooms often involve different protections—for example, moisture-prone areas like kitchens and bathrooms rely on GFCIs for shock protection—so the specific requirement for arc-fault protection is typically associated with bedrooms.
