The New UL GFCI Standard: SmartlockPro® Self-Test GFCIs From Leviton

Leviton SmartlockPro Self-Test GFCI

Testing The Limits

Since the swinging ‘70s, GFCIs have reduced electrocutions resulting from ground faults in residential settings. Users are supposed to test their GFCIs monthly, but that doesn’t always happen. If someone assumes a GFCI is functioning, and it isn’t, it could possibly be a very dangerous situation.

To address these issues, effective June 29, 2015, all GFCI receptacles and circuit breakers must have an auto-monitoring (self-test) feature that automatically conducts a periodic internal test to confirm that the GFCI is able respond to a ground fault. If a problem is detected, the GFCI must trip and deny power or provide a visual and/or audible indication.

Paving the Way In Electrical Safety

Leviton has responded to the new requirements with their SmartlockPro® Self-Test GFCIs that provide simple and intuitive feedback to the user on power and protection status (See diagram below). And, similar to prior models, Leviton offers the slimmest profile GFCI receptacles in the market for easy installation and all come standard with Leviton’s patented reset lockout mechanism, which prevents resetting of a GFCI if it is not wired and operating correctly.

Leviton SmartlockPro Self-Test GFCI

Green Status

    Dual indicator:
  • On initial installation - If no power to load, device has been wired incorrectly
  • Normal operation - GFCI has passed self-test and is providing power

Red Status

  • Blinking = Initial self-test upon first power up
  • Solid or blinking = Press TEST and RESET buttons to reset GFCI
  • If GFCI will not reset OR solid or blinking red continues, replace device

No Power

  • GFCI in tripped state, no power
  • Press RESET button
  • If GFCI will not reset, no power on the circuit


  • Leviton Patented Reset Lockout – Prevents reset if GFCI is damaged and cannot respond to a ground fault
  • Tamper-Resistant Shutters – Meets NEC® 406.12 requirement by blocking access to the contacts unless a two- or three-prong plug is inserted
  • Terminals Withstand High Torque – Tolerate high-torque power tool installation and prevents wire pullout
  • Back and Side Wire – Two convenient wiring options; the external clamp also provides visual indication of proper wire seating
  • Status Indicator Light – Red and green LED indications provide simple, intuitive feedback on power and protection status as well as correct wiring
  • Standard Self-Ground Clip – Grounds the device in grounded metal box installations
  • Only 1.026” Protrusion into Wallbox – Takes up to 25% less space in the wallbox vs. other GFCIs for easier installation
