Hubbell GFCI Receptacle 20A 125VAC

The Hubbell GFRTW20GRY is a 20-amp, 125-volt GFCI receptacle built for residential and light-commercial wiring. It provides ground-fault protection on a standard 5-20R outlet configuration. Electricians and facility managers specify it where NEC tamper-resistant and weather-resistant requirements apply.

AUTOGUARD self-test monitoring every 30 seconds

Patented AUTOGUARD technology runs an automatic self-test continuously within every 30 seconds to verify protection capability. If critical components fail, power is disconnected from the receptacle face. Clear visual indicators show power status, trip condition, ground-fault condition and end-of-life status without opening the device.

Line-load reversal protection denies power

The receptacle blocks power to the face and downstream terminals if line and load conductors are reversed during installation. It meets NEC 517-18c for tamper resistance and 406.9 for weather resistance, plus UV and corrosion resistance for harsh or damp locations. Compliance follows the 2015 UL 943 GFCI safety standard.

Questions about this item

How do I wire the GFRTW20GRY and what common mistake trips the line-load reversal protection?

Connect the supply conductors to the LINE terminals only; reversing line and load cuts power to the face and downstream until corrected.

When will the AUTOGUARD self-test indicate the receptacle has reached end of life?

The face indicator shows end-of-life status when internal monitoring detects the GFCI can no longer provide protection.

What is the first limitation that appears during continuous operation of this 20 A 125 VAC device?

The self-test cycle runs every 30 seconds and will disconnect power if protection is lost.
