GFCI Protection
GFCI protection is a safety feature that shuts off power when a ground fault is detected, reducing the risk of electric shock. A Ground Fault Circuit Interrupter monitors current flow and trips quickly if electricity is leaking from the circuit, such as through water or a person. GFCIs are required in wet or damp areas like kitchens, bathrooms, garages, and outdoors.

Quick Facts
How GFCI Protection Works
GFCIs trip fast to protect against electrical shock.
Real-World Application
A bathroom GFCI outlet trips when a hair dryer falls into the sink, cutting power before a dangerous shock can occur.
Pro Tip
Test GFCI outlets monthly using the Test and Reset buttons to confirm they work properly.
“Test GFCI outlets monthly using the Test and Reset buttons to confirm they work properly.”
Important Things to Keep in Mind
- GFCI protection can be at the outlet or breaker level.
- They are required by electrical code in wet and outdoor locations.
- GFCIs reduce shock risk but do not replace safe electrical habits.
Did You Know?
GFCIs have significantly reduced electrical injuries since their adoption in the 1960s.
