When your project calls for a dedicated 20-amp circuit — think commercial kitchens, laundry rooms, workshop benches, or any location with high-draw appliances — the Leviton SmartlockPro Self-Test GFCI Receptacle delivers the protection and reliability professional electricians and contractors demand. Rated at 20 A, 125 VAC with a NEMA 5-20R configuration, this tamper-resistant outlet automatically self-tests to confirm ground fault protection is active, exceeding UL requirements without any manual intervention. The patented Lockout Action prevents reset if the device is compromised, and the reduced depth fits easily into shallow electrical boxes — a real time-saver on tight rough-ins. Back and side wiring with external clamps for visual wire seating confirmation keeps your installations clean and inspection-ready. Carrying UL/CSA, Fed Spec WC-596, and full NEMA WD6 certification, this is the 20-amp GFCI you can confidently spec on any residential or commercial job.

Features & Benefits
- Provides continuous ground fault protection – detects and trips on actual ground fault even when self-test is being conducted
- On initial power up, tests the GFCI within 3 seconds
- Auto-monitoring exceeds the UL requirement
- Auto adapts and shifts to more frequent testing if potential problem is detected
- Status Indicator Light provides simple, intuitive feedback on power and protection status as well as indication of line/load reversal
- Patented Lockout Action prevents reset if GFCI is damaged and cannot respond to a ground fault
- Electronics are designed to minimise any false triggers
- Reduced depth makes it easier to install in any electrical box, even shallow ones
- Terminals allow for easy wiring options – back and side wire capable
- External back wire clamps provide visual indication of proper wire seating
- Withstands high torque and resists wire pullout
- Standard brass self-grounding clip
- Trip threshold meets or exceeds UL requirements for tripping time
- Improved immunity to high-frequency noise reduces nuisance tripping
- Advanced electronics design provides superior resistance to electrical surges and over-voltages
- Compatible with all Decora devices and wallplates; available in select Decora colours
- UL Fed Spec WC-596 rated
