What is a GFCI?
A ground fault circuit interrupter, or GFCI, is a special type of electrical switch or receptacle with a built-in circuit breaker. Houses built since the 1970′s use GFCI circuits in places where the circuit may be exposed to excess moisture, and are required by local laws in some locations. Installing a GFCI does not require an Electrician’s license, and won’t demand any previous knowledge of how household wiring is done, but faulty GFCI’s should be replaced right away to prevent serious electrical problems.
