What is a ground-fault circuit interrupter?
A ground-fault circuit interrupter, or GFCI, is a safety device that protects people from possible electric shock hazards. A typical GFCI is built into an electrical outlet to kill the power once an electrical fault is detected. The National Electrical Code (NEC), which regulates electrical wiring, has begun to require ground-fault circuit interrupters in more and more locations; particularly in damp locations in contact with the earth or concrete.
These are receptacles that typically have the black and red test buttons on them (pictured above). GFCIs are found in outlets and service panels. They monitor the flow of current to and from appliances. If there’s an imbalance in the flow, because of a frayed wire, a ground fault or a faulty device, current may attempt to travel through you, but the GFCI will quickly cut power to prevent any serious injury. Unless you have an outlet with a Ground Fault Circuit Interrupter (GFCI), you may be seriously shocked or burned because you may be the shortest route to the ground. Although they prevent electrocution, there is still a risk of electric shock. GFCI Receptacles (Ground Fault Circuit Interrupter) – Safety Receptacles They are required (by code) in many areas where electricity and water may come into contact. These areas include bathrooms, kitchen receptacles for countertop use within 6 feet of any sink, basements, pools, spas, laundry and utility rooms, garages and all receptacles loc
