Where GFCI Outlets Are Required (And Why Two-Prong Outlets Have to Go)

A room-by-room guide to where GFCI outlets are required, the difference between GFCI and AFCI, and how to deal with ungrounded two-prong outlets in older homes.

GFCI protection is the cheapest life-safety upgrade in a house. It watches for current leaking where it should not go and cuts power in milliseconds - long before your breaker would notice.

Where it is required

  • Bathrooms - all receptacles
  • Kitchens - all countertop receptacles
  • Laundry areas and near any sink
  • Garages and unfinished basements
  • Outdoors, including under decks
  • Crawl spaces
  • Near pools, hot tubs and wet bars

If your Maryland home still has plain receptacles in those spots, that is a short, cheap outlet installation visit.

GFCI vs AFCI

GFCI protects people from shock. AFCI protects the building from arc faults - the tiny arcing in a damaged cord or a loose terminal that starts fires. Bedrooms and living areas increasingly call for AFCI, and dual-function devices cover both.

The two-prong problem

An ungrounded outlet has nowhere to send fault current. Two legitimate fixes: run a proper ground, or install GFCI protection and label the outlet as ungrounded. What is not acceptable is the common shortcut of swapping in a three-prong receptacle with no ground behind it, which leaves the next owner assuming protection that is not there.

Test yours this weekend

Press TEST on each GFCI. Power should cut. Press RESET to restore. If it will not trip, or will not reset, replace it - they wear out, generally in about ten years. If a GFCI trips repeatedly, something on that circuit is actually leaking and needs tracing.
