GFCI (Ground Fault Circuit Interrupter)
A safety device that shuts off electrical power within milliseconds when it detects current flowing through an unintended path, like water or a person.
The Full Picture
A GFCI (Ground Fault Circuit Interrupter) continuously monitors the balance of electrical current between the hot and neutral conductors. When current flows through an unintended path — such as through water, a person, or damaged insulation — the GFCI detects the imbalance (as little as 4-6 milliamps) and trips the circuit in about 1/40th of a second. GFCIs are required by the National Electrical Code (NEC) in wet or damp locations: kitchens, bathrooms, garages, outdoors, basements, and near pools. They come as receptacles (outlets), circuit breakers, or portable devices.
Why It Matters
Why field professionals need to document this
Missing or non-functional GFCI protection is one of the most common findings in home inspections and electrical inspections. It's a safety issue that's relatively inexpensive to correct but critical to document. For electricians and home inspectors, testing every GFCI and documenting the results — including which outlets are protected and which aren't — is a standard part of every inspection report.
In a Report
How this shows up in findings
Here's how a gfci (ground fault circuit interrupter) finding looks in a professional field report generated by ReportWalk:
Kitchen GFCI: failed trip test on all 3 countertop receptacles — replacement required
Bathroom: GFCI protection present and functional — trips and resets properly
Outdoor receptacles: no GFCI protection — code violation per NEC 210.8
