The Leviton GFNT1-W is a 15-amp SmartlockPro Slim GFCI outlet in White — the non-tamper-resistant version for locations where children are not a concern, such as garages, laundry rooms, and outdoor-accessible utility spaces. The self-test function runs automatic internal checks to confirm the device can respond to a ground fault, meeting the latest UL 943 monitoring requirements without any manual testing. A single LED indicator provides real-time status feedback: solid green means the outlet is protected and ready, blinking red signals a wiring error, and no light indicates a tripped state. The slim-profile body fits standard single-gang and two-gang boxes including shallow boxes that would reject older bulkier GFCI units. Feed-through wiring at 20 amps lets one GFNT1 protect multiple downstream outlets from a single location. Comes with a nylon wall plate and self-grounding clip.
What is the difference between the GFNT1-W and the tamper-resistant GFTR1-W?
The GFNT1-W does not have tamper-resistant shutters inside the outlet slots, while the GFTR1-W does. Tamper-resistant shutters block objects inserted into a single slot, which reduces risk when children are present. The GFNT1-W is the right choice for garages, laundry rooms, basements, and other locations where the National Electrical Code does not require tamper resistance — it installs and resets identically to the TR version.
What does the LED indicator light mean on the GFNT1-W?
The LED provides three states: solid green means the outlet is correctly wired and actively protected against ground faults; blinking red indicates an internal fault or wiring error that prevents proper operation; no light means the outlet has tripped and power is interrupted. If you see blinking red after installation, the most common cause is line and load wires reversed — swap them and press TEST then RESET to restore operation.
Can I use one GFNT1-W to protect multiple outlets downstream?
Yes. The GFNT1-W supports feed-through wiring rated at 20 amps. Connect your incoming line wires to the LINE terminals and your downstream outlets to the LOAD terminals. Any outlet wired to the LOAD side will be GFCI-protected by the single upstream GFNT1-W, even if those downstream outlets are standard non-GFCI receptacles.
How does the self-test feature work?
The GFNT1-W automatically runs internal ground-fault detection tests at regular intervals without interrupting power to plugged-in devices. This meets the UL 943 requirement for auto-monitoring GFCIs. If the self-test detects a fault in the protection circuit itself, the outlet trips and locks out — the LED blinks red and the device cannot be reset until replaced, ensuring a failed GFCI does not silently stop protecting.
Will the GFNT1-W fit in a shallow electrical box?
Yes. The SmartlockPro Slim design is one of the shallowest GFCI profiles on the market and is engineered to fit in shallow single-gang boxes where older bulkier GFCIs would not. The reduced depth also makes it easier to push the device into a box that already has multiple wire connections. Standard 1-gang boxes 1-1/2 in. deep or deeper are compatible.
