GFCI protection is vital to ensure electrical safety in both residential and commercial settings. A power interruption due to a ground fault provides important protection to people but can shut down freezers, sump pumps and other necessary equipment if left undetected. Often, however, GFCIs in garages, basements or large commercial kitchens may be located in an out-of-the-way place such as a back corner or storage area making daily visual checks for tripping unlikely.
