The self-test SmartlockPro® slim GFCI/Guide light is a great way to add an extra element of safety when it's dark without losing outlet space in kitchens, bathrooms, laundry rooms and hospitality guest suites. Instead of needing to plug-in a nightlight and take up an outlet space, the device offers dual LED guide lights that turn ON and OFF automatically based on light levels and uses only 1 W of electricity. Designed to meet the latest UL standard for auto-monitoring (self-test) our complete line of self-test GFCIs periodically conduct an automatic internal test to confirm that it can respond to a ground fault. With the slimmest profile ON the market, the device allows for fast and easy installation, while Leviton® patented reset lockout mechanism prevents reset of the GFCI if it is not wired or operating correctly. The self-test SmartlockPro® slim GFCI/Guide light is the smart choice in ground fault circuit interrupter protection.
The Leviton GFNL1-W SmartlockPro® Self-Test GFCI Receptacle is a 15A, 125V duplex feed-through GFCI with an integrated guide light, self-test functionality, tamper-resistant protection, and LED status indication. It is designed for residential and commercial locations where GFCI protection is required, particularly in wet or damp areas.
