Hubbell CR5352IG Isolated Ground Duplex Receptacle 20A

Product Description

The HUBBELL CR5352IG is a heavy-duty isolated ground duplex receptacle rated for 20 amperes at 125 volts with a 5-20R configuration. It features a nylon finder groove face for high-impact resistance and a polybutylene terephthalate (PBT) base for durability under demanding conditions. The isolated grounding design keeps the equipment ground path separate from the standard grounding circuit, reducing electrical noise in sensitive installations. Combination Phillips/slotted screws and pretensioned ground contacts simplify installation and ensure positive ground continuity. Large oxide-cutting terminal screws support reliable, low-resistance connections. Approved to UL 498, CSA C22.2, and Federal Specification WC596. Licensed electricians handle installation in commercial and construction-grade applications.

The CR5352IG is suited for commercial, construction, and heavy-duty industrial environments where equipment-sensitive circuits require isolated grounding to minimize electrical noise and interference. Typical applications include computer rooms, medical facilities, and any installation where sensitive electronic equipment demands a clean ground path. Back and side wiring options accommodate a range of box configurations and conduit layouts. The receptacle ships in brown and is built for high-traffic, high-demand outlet locations.

Key Features

• Isolated grounding separates equipment ground from building ground, reducing electromagnetic interference
• Nylon finder groove face provides high-impact resistance and easy outlet identification
• Pretensioned ground contacts ensure positive, consistent ground continuity
• Large oxide-cutting terminal screws deliver reliable, low-resistance terminations
• Combination Phillips/slotted screw terminals for fast, flexible installation
• Heavy-duty, construction-grade rating for demanding commercial environments

Compatibility

Designed as an OEM-style isolated ground duplex receptacle for heavy-duty commercial and construction-grade wiring device applications where a 5-20R, 20A, 125V configuration is specified.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NFPA 70 (NEC) requirements, including applicable isolated ground circuit rules under Article 250. De-energize the circuit at the breaker panel and verify absence of voltage before making any connections. Both back-wire and side-wire terminations are available on this device. The isolated ground terminal must be connected to an insulated isolated equipment grounding conductor run back to the panel as required by code.
