In dwelling units, which locations require GFCI protection for personnel?

• A. Bathroom, garage, and outdoor areas
• B. Bedroom, living room, and kitchen
• C. Basement and attic
• D. Hallways and stairways

Answer: (A)

GFCI protection is used to protect people from electric shock by quickly cutting power when current leaks to ground. It is especially important in areas where moisture or water is present, because water increases the risk of shock.

In dwelling units, the locations that require GFCI protection for personnel are bathrooms, garages, and outdoor areas. Bathrooms have sinks and showers, garages often handle damp conditions and tools, and outdoor areas are exposed to rain and splash. In these wet or damp environments, a fast trip by a GFCI outlet dramatically reduces the chance of a dangerous shock.

Other spaces listed are generally not mandated for universal GFCI protection in typical scenarios: hallways and stairways are usually dry, and many interior living spaces like bedrooms and living rooms don’t require GFCI for all receptacles. Basements and attics depend on moisture conditions and space type, but the combination of bathroom, garage, and outdoors is the trio most consistently required for GFCI protection.
