Product Description - White 20A Tamper-Resistant Self-Test GFCI Receptacle (UL 943)

White 20A Tamper-Resistant Self-Test GFCI Receptacle (UL 943)

The White 20A Tamper-Resistant Self-Test GFCI Receptacle is a commercial-grade, specification-grade life safety electrical device engineered to deliver continuous ground fault circuit interruption protection. Fully compliant with the rigorous benchmarks of the newer UL 943 standard, this high-performance receptacle features an intelligent auto-monitoring self-test framework that routinely runs background diagnostic checks to verify internal safety mechanics are active. Built for intensive deployment across both commercial and residential footprints, it includes an advanced reverse line-load misfire mechanism that completely denies electrical power to the receptacle face and down-line loads if cross-connected during setup or re-installation. Its integrated end-of-life lock-out system permanently prevents the reset button from engaging if internal protection circuitry is compromised or damaged. Outfitted with spring-loaded Tamper-Resistant (TR) shutters to keep foreign objects away from live terminals, this corrosion-resistant, drop-tested unit provides a clean architectural aesthetic alongside simplified wiring paths for fast, code-compliant installations near water sources.

Key Features

• Automatic Self-Testing Diagnostics: Internal microchip architecture continuously runs automated background checks to verify critical Class A safety mechanics, satisfying strict UL 943 engineering guidelines.
• Tamper-Resistant (TR) Safety Shutters: Equipped with permanent internal safety shutters that slide shut to block single-prong items like hairpins or keys, while allowing standard two-prong electrical plugs to insert smoothly.
• Reverse Line-Load Miswire Protection: Advanced safety layout locks out all output voltage to the receptacle face if incoming line and down-line load wires are accidentally reversed during initial field installation.
• Compromised Protection Reset Lock-Out: Built with an intelligent lock-out function that causes the tactile mechanical reset button to refuse to click down or reset if internal protection elements reach end-of-life or sustain physical damage.
• Rugged Impact-Resistant Enclosure: Fabricated from structural engineering thermoplastic that passes strict drop and high-impact structural testing, preventing cracks or face fracturing in demanding high-traffic environments.
• Corrosion-Resistant Interior Metallurgy: Outfitted with premium internal sub-components and treatment layers designed to prevent terminal oxidation and maintain electrical grid integrity in humid spaces.
• Streamlined Terminal Wiring Assembly: Features oversized brass terminal clamps with color-coded wiring paths to support rapid, straightforward rear back-wiring or traditional side wire loops.
