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.
