Ground Fault Circuit Interrupter (GFCI or sometimes GFI) receptacles provide a higher level of safety and help prevent injuries by shutting off power when device is tripped. These safety GFI electrical devices feature reset buttons.
Requirements: Building codes require installation of GFCI outlets in areas near water sources such as in your kitchen, laundry room, bathroom or garage. It may not be necessary to install a GFCI outlet for all your outlets near water as long as the first one in a series (closest to the electrical panel) is a ground fault protected device. The first GFCI can trip or shut off other receptacles further down the circuit if they experience a short. (Check your local building codes for requirements needed to pass inspection.)
