Color: White 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.
