Tamper-Resistant GFCI Duplex Receptacle, 20A 125V, Commercial Grade, UL Listed

A tamper-resistant GFCI duplex receptacle rated 20A at 125V, 60Hz, specified for commercial and industrial branch circuits requiring ground fault protection and physical tamper resistance. Feed-through modular terminals accept 12-14 AWG conductors, and the device mounts on a zinc-plated steel yoke. Two indicators report status: a green LED confirms correct installation and active protection, while a red LED blinks during the automatic self-test performed every 40 seconds and turns solid at end of life. Trip threshold is 4-6 mA with a trip time under 25 ms. The high-impact PC enclosure carries a UL94-V0 flame classification, dielectric withstand is 1,500 V AC, and mechanical life is rated at 6,000 operations. The receptacle is UL Listed to UL 498 and UL 943 and is covered by a 1-year warranty.
