Hubbell GFCI Receptacle 20A 125V

The Hubbell GFRTR20BLK is a 20-amp, 125-volt ground-fault circuit interrupter built for residential and light-commercial wiring. It suits electricians and facility managers who need code-compliant protection on branch circuits. The black nylon face fits standard wall plates and matches modern décor. Buyers who need higher amperage or a different voltage rating should select another model.

Self-Test Monitoring and Trip Indication

Patented AUTOGUARD® self-test technology runs a diagnostic check every 30 seconds to verify protection integrity. If critical components fail, power is automatically disconnected from the receptacle face. Clear visual indicators show power status, trip condition, ground-fault state and end-of-life status without opening the device. Reverse line-load wiring is also detected and power is denied to prevent mis-wired installations.

Tamper-Resistant Shutters and NEC Compliance

A patented shutter mechanism blocks access to the contact openings unless both plug blades are inserted simultaneously, meeting NEC® 406.12 tamper-resistant requirements. The device also satisfies NEC® 517-18(c) for healthcare applications. Triple-wipe construction improves contact reliability over the service life. No additional accessories or software are bundled; the safety features are integral to the receptacle itself.

Questions about this item

How do I wire the 20A 125V receptacle and which step causes the AUTOGUARD self-test to deny power?

Connect line conductors to the LINE terminals and load conductors to the LOAD terminals; if line and load are reversed the self-test will deny power to the face.

What maintenance or replacement will the GFCI need after the self-test indicates end of life?

The device face shows an end-of-life indicator; when lit the receptacle must be replaced because the AUTOGUARD monitoring has detected lost protection capability.

What limit appears first during sustained use if the self-test runs every 30 seconds?

Continuous self-testing every 30 seconds will eventually trigger the end-of-life indicator, signalling that internal components can no longer guarantee ground-fault protection.
