NHIE exam practice question · Interior
GFCI protection interrupts a circuit when current returns by an unintended path — through a person, for example — and it is required in locations where water, damp conditions or grounded surfaces raise the risk of that happening. Garages are on that list because of concrete floors, moisture, vehicle washing and the outdoor tools that get plugged in there. An older garage receptacle without protection was probably compliant when installed, since the requirement was extended to garages at a particular point in the code's history, so the inspector is not reporting a violation of the rules in force at the time. What they are reporting is a present-day safety gap with an inexpensive remedy, which is exactly the shape of a recommended safety upgrade: note the condition, explain the risk, recommend the improvement without characterizing the original work as defective.
A garage is a damp location where GFCI protection is now required, and an unprotected receptacle there is a real shock hazard with an inexpensive fix. Reporting it as a recommended safety upgrade conveys the risk without mischaracterizing installation that was compliant when built.
GFCI protection is required in bathrooms, kitchens, garages, unfinished basements, crawl spaces, outdoors and other damp or wet locations, with the list expanded over successive code cycles. Inspectors report missing protection in these locations as a recommended safety upgrade even where the installation predates the requirement.
Old but Still Unsafe. It may have been legal when built, and it is still a shock hazard today. Report the upgrade, not a violation.
Know the full list of GFCI locations — kitchens, bathrooms, garages, basements, crawl spaces, outdoors, near sinks. Missing protection in any of them is commonly tested.
