When your project demands dependable ground fault protection on a dedicated 20-amp circuit — commercial kitchens, laundry rooms, workshop benches, or any location with high-draw appliances — the Leviton SmartlockPro Self-Test GFCI Receptacle is the outlet professional electricians and contractors reach for. Rated at 20 A, 125 VAC with a NEMA 5-20R configuration, it 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 WD-6 certification, this is the 20-amp GFCI you can confidently specify on any residential or commercial job.
