In which area of a dwelling unit is GFCI protection required?

GFCI (Ground Fault Circuit Interrupter) protection is required in areas where there is an increased risk of electric shock due to the presence of moisture. Bathrooms are considered wet locations, and the National Electrical Code (NEC) mandates the installation of GFCIs in such environments to protect individuals from potential electrical hazards.

In bathrooms, the likelihood of water coming into contact with electrical devices is heightened due to sinks, bathtubs, and showers, making GFCI protection critical for safety. This requirement helps ensure that if there is a ground fault, the GFCI will quickly cut off the electrical supply, greatly reducing the risk of electric shock.

While garages also require GFCI protection due to potential moisture and dampness, the question specifies a dwelling unit's areas targeted for particular focus, where bathrooms are the highest priority. Living rooms and bedrooms are not typically classified as locations requiring GFCI protection, as they do not present the same level of risk associated with moisture exposure. Hence, recognizing the specific requirements for bathroom safety underscores the importance of GFCI installations in residential settings.
