A History Of GFCi - Ground Fault Outlet Installation Dates And Locations


A GFCI receptacle (outlet) is designed to shut of electric power within 1/40 of a second in order to prevent electric shock.


Ground fault circuit interrupter receptacles (outlets) have been required in houses since 1971. Originally they were only required on the exterior of the house and by swimming pool equipment. Over the years GFCI outlets have been required in more locations, such as in garages, bathrooms, kitchens, etc.


GFCI outlets are commonly found in areas that are highly susceptible to ground faults, such as where there is a risk of water coming in contact with electricity.

In those areas it is important that GFCI outlets be installed in order to prevent shock hazards - electrocution.


If your house does not have GFCI protection in the following listed areas my recommendation is to have a licensed electrician provide this life-saving protection in all of those noted areas.
