Eaton TWRGF20BK-50 Slim GFCI Receptacle - cULus Listed
Part Number: TWRGF20BK-50
Quick Summary
The Eaton slim GFCI receptacle provides ground fault protection for outlets in outdoor and damp industrial enclosures. A common challenge is fitting code-compliant protection into tight panels and weather-exposed locations, where bulky devices slow installations and increase labor costs. With self-test operation, tamper resistance, a slim footprint, and factory-wired back-and-side wiring options, it reduces maintenance cycles and space risk while speeding up electrical pull-through. Additionally, cULus Listed and NOM certified, the product aligns with NEC and local code requirements, supporting rapid project approval and streamlined bulk procurement for distributors and integrators. Its bulk-packaged configuration (50 units per pack) supports efficient stocking and faster field replacement in high-volume electrical installations.
