Many of my home inspection clients are unclear about what the difference is between a Ground Fault Circuit Interrupt (GFCI) an Arc Fault Circuit Interrupt (AFCI), so I thought it might be a good idea to present a little information about these two potentially lifesaving devices.
A GFCI, which can be located either in the electrical panel or at the receptacles in the home that need them. They are used to protect the home owner from water related electrocution, so they are found in locations where there is a water source nearby. This would include the kitchen, the bathrooms, the garage, and the exterior of the home. If you are touching water and electricity at the same time, these GFCI breakers will trip and prevent you from getting electrocuted or shocked. Newer homes are required to have them in all the areas I have described, but older homes should have them also, because they can save your life.
An AFCI, is usually located in the electrical panel and they are there to keep fires from starting when wires overheat. They detect very small electrical fluctuations and trip the breaker before the wires can heat up enough to start a fire.
Very few older homes have AFCI breakers unless they have been through an electrical renovation, but new homes are required to have them on all 15 and 20 amp branch breakers providing power to outlets in residential family rooms, dining rooms, living rooms, parlors, libraries, dens, bedrooms, sun-rooms, recreation rooms, closets, and hallways.
You can see why it is a good idea to have them in your home and why it might be a good idea to see about upgrading any home to have them, whether it is required by code or not.
As always, I welcome any questions you might have about your home or having your home inspected.
