15 Amp 125 Volt Receptacle/Outlet 20 Amp Feed-Through Self-test SmartLock Pro Slim Weather and Tamper-Resistant GFCI Monochromatic back and side wired wallplate/faceplate sold separately - Light Almond Peace of mind all the time. The SmartlockPro Self-Test GFCI tests itself even if you forget. 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 s patented reset lockout mechanism prevents reset of the GFCI if it is not wired or operating correctly. The SmartlockPro Self-Test GFCI is the smart choice in ground fault circuit interrupter protection.
