Night-light and tamper-resistant design enhance safety and deter tampering, reducing risk to occupants and lowering call-backs for facilities. The business impact is clearer corridors and busy workspaces where easy visibility and child-safety features matter; the application spans residential hallways, commercial restrooms, and common-area outlets. The self-test GFCI function automatically verifies trip integrity, increasing system reliability and reducing maintenance costs by catching degraded protection before it fails in service. This feeds into a faster, compliant installation workflow for engineers and electricians, especially in kitchens, laundry rooms, and service panels where NEC compliance is critical. Back-and-side wiring support up to #14–10 AWG enables flexible retrofits and new-construction installs without reconfiguring outlet boxes. The NEMA 5-20R configuration provides compatibility with common 125V circuits, while flush mounting delivers a clean, professional finish in both new-build and renovation projects. Brass contact material ensures solid conductivity and consistent performance, and the black face with polycarbonate body resists wear in high-traffic environments. Torque rating of 16 lbf-in supports secure connections in demanding installations, reinforcing long-term reliability for mission-critical outlets in commercial facilities.

FAQs
Installers connect line and load conductors using back and side entries, accommodating #14 to #10 AWG conductors. Ensure the wires are firmly secured under the terminals and the device is flush-mounted in a compatible electrical box. This wiring flexibility supports retrofits and new installations alike, reducing scheduling constraints on project sites.
The self-test automatically checks the trip mechanism to verify proper ground-fault protection, confirming device readiness without manual testing. This reduces the risk of undetected protection failure, helping facilities maintain safety standards and stay compliant with NEC requirements in high-use areas.
Yes. The TRSGFNL20BK is designed for both residential and commercial environments, offering a nightlight for visibility and tamper-resistance to deter interference. Its 20A/125V rating and NEMA 5-20R configuration ensure broad circuit compatibility across typical building applications.
The receptacle is cULus Listed and UL Listed, confirming compliance with safety and performance standards for electrical devices used in North American installations. This dual listing supports confident integration into both new builds and renovations.
By delivering automatic self-testing, tamper resistance, and a night-light, the TRSGFNL20BK reduces nuisance trips and occupancy-related incidents. The durable polycarbonate body and brass contacts improve longevity, lowering replacement costs and service calls while supporting safer, code-compliant operation across high-traffic areas.
