A Ground Fault Circuit Interrupter (GFCI) is an important safety device which helps protect people from electric shock and electrocution due to hazardous ground-faults. Ground-faults occur when a current flows along an unintended path, such as through water or a person. For example: Operating electrical equipment in wet or damp conditions, electrical current leaks from appliances or tools or when electrical wiring becomes frayed or damaged. Leviton GFCIs help protect people while meeting or exceeding National Electric Code (NEC) standards. No matter what your installation needs are, we have a GFCI that's right for you. Available options in the Leviton line include Standard, Weather-Resistant, Combo GFCI/USB, Combo GFCI/Switch, Guide Light, Audible Alert, Wi-Fi GFCI, Blank Face, Dual-Function AFCI/GFCI and GFCI Circuit Breakers. Continuously protects against electric shock electrocution by interrupting power if a ground-fault is detected. Required by the NEC for areas around the home within a close proximity to a water source (kitchen, bathroom, laundry room, basement, garage/carport, pool area). Patented reset/lockout feature prevents reset if the GFCI is unable to respond to a ground-fault or if it isn't wired properly. Regularly conducts an automatic self-test to ensure safety. LED indicator provides simple, intuitive feedback on power and protection status. Tamper-resistant shutters prevent foreign objects, such as keys, from being inserted into the outlet.
