What is a GFCI?
GFCI is an acronym for Ground Fault Circuit Interrupter; it sometimes is referred to a GFI. This device acts as a safety device by sensing when current flowing thru it has found an unintended path, such as water or something metallic or a person. Typically, a GFCI is factory set to open the ungrounded conductor or “trip” at around 15ma. GFCI protection is required by the National Electric Code in all bathrooms, garages, outlets above the counter in kitchens, exterior outlets, and unfinished basements, etc.
