Hubbell GFR20W GFCI Duplex Receptacle

The Hubbell GFR20W is a 20-amp, 125-volt AC duplex receptacle with NEMA 5-20R configuration. It incorporates AUTOGUARD self-test technology that checks ground fault protection every 30 seconds. Visual indicators show power status, trip condition, ground fault detection, and end-of-life state. The unit cuts power when GFCI protection is lost or reverse wiring is detected.

Suited For And Not Suited For

This receptacle suits commercial and industrial installations requiring 20-amp GFCI protection with continuous self-monitoring. It fits single-gang flush-mount boxes and accepts both back and side screw terminal connections. It is not for circuits requiring a different amperage or voltage rating, applications that specify a non-GFCI device, or mounting configurations other than single-gang flush mount.

Critical Specification

The decisive specification is the NEMA 5-20R 20-amp 125-volt rating combined with the self-testing GFCI function. This defines the circuit capacity, voltage class, and the automatic safety verification that the device provides. Match this rating to the branch circuit and local code requirements before installation.

Questions about this item

What circuit breaker rating is required for the 20 A NEMA 5-20R duplex receptacle?

The receptacle is rated for 20 A at 125 V AC, so it must be installed on a 20 A branch circuit with wiring sized for that load.

Can the self-test feature operate correctly on an older electrical panel without modern AFCI breakers?

Yes, the AUTOGUARD self-test runs every 30 seconds independently of the panel; it only monitors the receptacle's own GFCI circuitry.

How do I confirm the GFCI is protecting the circuit after installation?

The face indicators show power status, trip condition, ground fault detection and end-of-life; a steady power light means protection is active.
