In which area must receptacles have GFCI protection?

While all choices listed often require GFCI protection based on specific conditions and locations, the bathroom is uniquely critical because of the high potential for electrical shock due to the proximity of water sources.

GFCI, or Ground Fault Circuit Interrupter, outlets are designed to quickly shut off power when they detect a ground fault, which occurs when electricity flows outside of its intended path, often due to contact with water. In a bathroom, where dampness and water from faucets or showers can easily create hazardous conditions, the need for GFCI protection is paramount.

In this context, the presence of water significantly increases the risk of electric shock, making GFCI protection essential in bathrooms to enhance safety for users. Other areas like kitchens, garages, and outdoor areas also have requirements for GFCI protection, but bathrooms stand out as particularly vulnerable environments that necessitate this protective measure.
