Hubbell GFRST20W 20A Commercial Self-test Gfci Receptacle

Product Description

The HUBBELL GFRST20W is a 20-amp commercial-grade self-test GFCI receptacle designed for ground-fault circuit-interrupter protection in commercial and light industrial electrical installations. This device continuously monitors the circuit for ground faults and automatically performs self-testing to verify proper protection without requiring manual intervention. Rated at 20 amps, it is suitable for demanding commercial environments where code-required GFCI protection must remain reliable over the life of the installation. Licensed electricians and electrical contractors are the primary installers of this device.

This receptacle is used in commercial new construction and retrofit applications where NEC-required GFCI protection is mandated, including kitchens, restrooms, mechanical rooms, wet bars, and outdoor locations. The self-test functionality reduces maintenance burden in commercial facilities where manual test-and-reset verification by staff is impractical. It mounts in a standard single-gang electrical box and is finished in white, making it suitable for general commercial interiors.

Key Features

• Self-test technology automatically verifies GFCI protection without manual testing
• 20-amp rating supports commercial-grade circuit loads
• Commercial-grade construction for durability in high-use environments
• White finish suits standard commercial and light commercial interiors
• Ground-fault protection helps meet NEC installation requirements for wet and damp locations

Compatibility

Designed as an OEM-style replacement or new-installation GFCI receptacle for standard single-gang commercial electrical boxes requiring 20-amp ground-fault circuit-interrupter protection.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always shut off the branch circuit breaker and verify the circuit is de-energized with a non-contact voltage tester before beginning work. Connect line-side wiring to the LINE terminals only, as incorrect connection to the LOAD terminals will result in loss of protection. Follow the manufacturer wiring diagram included with the device for proper lead termination.
