The LEVITON MFG CO R12-GFNT1-0KW is a 15-amp, self-testing slim GFCI outlet designed to protect against electrical shock and electrocution by interrupting power the moment a ground fault is detected. The device runs automatic self-tests continuously, eliminating the need for manual testing intervals. Its slim profile reduces installation depth behind the cover plate, making it practical for boxes with limited clearance. A reset lockout feature prevents the outlet from resetting if it is miswired or has failed, ensuring a non-functional device cannot be put back into service unnoticed. Licensed electricians and qualified electrical contractors are the typical installers for this device.
This GFCI outlet is suited for residential and light commercial locations where NEC code requires ground-fault protection. Common installation areas include kitchens, bathrooms, laundry rooms, basements, garages, and outdoor spaces — any location near a water source where ground-fault hazards are present. The device meets or exceeds National Electric Code requirements and satisfies current UL standards for auto-monitoring, making it appropriate for new construction, remodel work, and direct replacement of non-GFCI receptacles in protected circuits.
Designed as an OEM-style replacement or new-installation GFCI receptacle for standard 15-amp residential and light commercial branch circuits requiring ground-fault protection per NEC guidelines.
Installation should be performed by a licensed electrician in accordance with NEC requirements and all applicable local electrical codes. Shut off the branch circuit breaker and verify the circuit is de-energized with a non-contact voltage tester before wiring. Follow the line and load terminal labeling on the device precisely — incorrect wiring will trigger the reset lockout and prevent the outlet from functioning. Do not force a reset if the lockout is engaged; diagnose and correct the wiring fault first.
