Advancements in electrical protection devices help keep homes and businesses safe. These devices include ground fault circuit interrupters (GFCIs) and arc fault circuit interrupters (AFCIs). Both help prevent electrical shock and fires caused by erratic surges in electrical current.
GFCI outlets are designed to trip when they sense even a minor imbalance in current between the hot (black) and neutral (white) legs of an electrical circuit. They cut off power to the receptacle in a fraction of a second — fast enough to avoid a potentially fatal shock. Although requirements vary by location, GFCIs are generally found in kitchens, bathrooms, basements, garages and other areas where water may be present, such as a workshop. GFCI outlets have test and reset buttons, and it’s a good idea to test them monthly to make sure they are operating properly.
AFCI outlets are designed to help prevent fires caused by arcing faults — erratic current flows that get hot enough fast enough to start a fire without ever tripping the breakers. In many areas, AFCIs are required on branch circuits that serve residential bedrooms in newly constructed homes. Existing structures are not required to have AFCIs, but it may be a good idea to look into having them installed in your home. A home inspector can help pinpoint areas where added safety measures such as AFCI or GFCI outlets could help protect your family.
NPI and GPI home inspectors have the tools and knowledge to assess your home. Consult with your local NPI or GPI inspector for an assessment of your home and its electrical system.
