GFCI protection prevents electric shock, while AFCI protection prevents fires caused by arcing. Modern code requires both in different locations.

A GFCI protects people from electric shock by detecting current leaking to ground. An AFCI protects property from fire by detecting dangerous arcing in wiring. They solve different problems and are required in different areas of a home.

Where GFCI protection is required

  • Kitchens and countertop outlets
  • Bathrooms
  • Laundry areas
  • Basements and garages
  • Outdoor receptacles
