20A GFCI Receptacle for Commercial Use

The Hubbell GFBF20GY is a 20A, 125VAC blank-face GFCI receptacle designed for commercial wiring where ground-fault protection is required. It installs flush with included hardware at a 3.27 in centre-to-centre height and accepts back or side wiring through screw terminals with an internal clamp. Brass contacts and a nylon housing sit inside a NEMA 6 rated enclosure, and the unit carries ADA, CSA and UL listings meeting NEC requirements.

Autoguard Self-Test for Continuous Monitoring

The integrated AUTOGUARD self-test runs a protective-function check every 30 seconds and automatically disconnects power if protection capability is lost. Visual indicators on the face show device status, and the receptacle denies power when reverse wiring is detected. Automatic reset restores service after a trip event without manual intervention. This device suits contractors and facility managers who need code-compliant, self-monitoring protection on 20A branch circuits.

Blank Face Requires Separate Cover Plate

The blank-face format means no integral receptacle slots are present; a compatible cover plate or device mount must be supplied separately to complete the installation. Buyers who need a ready-to-plug GFCI outlet with built-in slots should select a standard duplex or decora-style GFCI instead.

Questions about this item

What mounting hardware and spacing does the GFBF20GY receptacle need?

The device flush-mounts with included hardware; the mounting holes are spaced 3.27 inches centre-to-centre.

How is the receptacle wired and what mistake should be avoided?

Use back or side screw terminals with the internal back-wiring clamp and guide; reverse wiring is detected and will prevent power from being supplied.

The integrated AUTOGUARD® function tests protective circuits every 30 seconds and disconnects power automatically if protection capability is not detected.
