Check Your Home for GFCI Protection
Check your home’s electrical outlets to see if any have ground fault circuit interrupters, or GFCIs, like the one shown here. Building codes in most states now require that GFCI outlets be installed in “wet” locations such as kitchens, baths, laundry rooms, garages, or any place there is danger from moisture-related electrical shock.
A GFCI has its own built-in circuit breaker that can sense an electrical imbalance, or fault, and instantaneously shut off power at the outlet to prevent user shock or a short circuit. Electrical systems in many existing homes have not been upgraded with these modern protection devices, but they are easy to install as replacements for standard outlets.
