Hubbell IG20CRI Isolated Ground Duplex Receptacle 20A 125V

Product Description

The HUBBELL IG20CRI is a smooth face duplex receptacle rated at 125 volts and 20 amperes, built to commercial and specification grade standards. It features an isolated ground design that separates the ground contacts from the mounting strap using an insulation barrier — a configuration commonly specified in healthcare, laboratory, and sensitive electronics environments where electrical noise on the ground path must be minimized. The face and base are constructed of nylon in an ivory finish. A triangle marking on the face identifies this unit as an isolated ground receptacle per NEC convention. Licensed electricians are the typical installing trade for this device.

The IG20CRI is suited for commercial and specification grade wiring projects where a NEMA 5-20R, 2-pole, 3-wire configuration is required. Its isolated grounding characteristic makes it appropriate for circuits serving computer equipment, medical devices, audio/visual systems, and other loads sensitive to ground-path interference. Back and side wiring capability accommodates both solid and stranded conductors, making it adaptable to a range of installation conditions in commercial office, healthcare, laboratory, and institutional facilities.

Key Features

• Isolated grounding with insulation barrier construction keeps ground contacts electrically separated from the galvanized steel mounting strap
• NEMA 5-20R configuration rated at 20 amperes and 125 volts
• Smooth face duplex layout with triangle marking on face identifying isolated ground status per NEC convention
• Wrap-around locked mounting strap provides additional structural support for the receptacle assembly
• Back and side wiring capability accepts both stranded and solid wire for installation flexibility
• Nylon face and base construction rated for operating temperatures from -40 to 75 degrees C
• Approvals: UL 498, CSA, FSUL WC596

Compatibility

Designed as an OEM-style commercial and specification grade replacement or new-installation isolated ground duplex receptacle for NEMA 5-20R circuits in 125-volt, 20-ampere branch circuit applications.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the branch circuit at the panel before beginning any wiring work. This receptacle is intended for isolated ground circuits — verify that the isolated ground conductor is run separately back to the panel per NEC Article 250 requirements. Do not use this device as a standard receptacle replacement where isolated grounding is not specified or wired.
