Where are GFCIs typically required in residential wiring?

• A. In wet or damp locations such as kitchens, bathrooms, outdoors, and garages.
• B. Only in bedrooms
• C. In dry, non-humid locations
• D. Only in living rooms

Answer: (A)

GFCIs are designed to protect people from electric shock by shutting off power when a ground fault is detected. In residential wiring, they are required in locations where moisture or water is present, because water increases the risk of shock. That’s why they’re typically needed in wet or damp areas such as kitchens, bathrooms, outdoors, and garages. In dry, non-humid spaces like bedrooms or living rooms, the risk from water isn’t a factor, so GFCI protection isn’t usually required by code there. GFCIs can come as receptacles or as circuit breakers, and they should be tested monthly to ensure they will trip correctly if a fault occurs.
