GFCI outlets and breakers are essential safety devices that protect against electrical shock in areas prone to moisture—bathrooms, kitchens, basements, garages, and outdoor outlets. They detect dangerous ground faults and interrupt power in milliseconds, preventing serious injury or death. Code requires GFCI protection for all kitchen countertop outlets, bathroom outlets, garage outlets, and outdoor outlets. Inspectors verify GFCI protection presence and operability by testing.
Pro Tip
Test GFCI outlets monthly using the test button. Frequent tripping suggests an underlying issue.
Example
A home inspection found a bathroom with standard outlets lacking GFCI protection, a serious code violation in all jurisdictions. The homeowner hired an electrician to install GFCI-protected outlets throughout the bathroom and other required areas, improving safety.
