Leviton SmartlockPro self-test GFCI receptacle rated 20A / 125V with 20A feed-through. The self-test circuit automatically verifies the GFCI's sense electronics every few seconds per UL 943 (revised 2015) - older GFCIs depended on the homeowner to press the TEST button monthly, and an untested unit could fail silently leaving the receptacle live but un-protected. SmartlockPro self-test runs the verification continuously and trips the receptacle on an internal fault so end-of-life isn't a silent failure. Tamper-resistant shutters meet NEC 406.12 for residential dwelling units, and the reduced-depth body fits shallow remodel boxes that a standard GFCI won't accept.

• Rating: 20 Amp, 125 Volt, 60 Hz with 20A feed-through downstream
• Self-test compliance: UL 943 (auto-monitor every few seconds)
• Tamper-resistant shutters: NEC 406.12 compliant for residential install
• Indicator LED: Green = power and protection OK; red flashing or solid = end-of-life or trip condition
• End-of-life response: Reset lockout - the device will not reset once the protection circuit fails (no silent failure)
• Terminals: Back-and-side wire compatible with 14 - 12 AWG copper
• Reduced-depth body fits shallow remodel and old-work boxes
• Self-grounding mounting yoke clip - no separate ground pigtail needed in grounded metal boxes
• Color: White
• Wall plate included

NEC 210.8 install locations: GFCI protection is code-required at receptacles in bathrooms, kitchen counter outlets within 6 ft of a sink, laundry areas, garages, outdoors, unfinished basements, and crawl spaces. The 20A version (vs the 15A version) is the right pick for kitchen counter circuits feeding small appliances, garage shop circuits, laundry circuits feeding washer + utility outlets, and any outdoor circuit dedicated to a 20A load (well pump GFI, pool pump receptacle, etc.). 20A GFCI receptacles install on either 15A or 20A circuits - never install a 15A GFCI on a 20A circuit feeding a dedicated 20A load.

Tip: White is the most common new-construction finish and the right pick when you're matching standard white wall plates, white-finish toggle and decora switches, or coordinating with white smoke detectors and thermostats. Pairs cleanly with white screwless wall plates for a flush modern look. Use the included white wall plate as a single-gang quick install, or swap for a Decora-style plate to coordinate with the rest of the room.
