HUBBELL GFCI

Hubbell is a long-established American manufacturer of electrical and electronic products, with a history dating back to 1888. The company's Ground Fault Circuit Interrupter (GFCI) product line is a core offering within its wiring device portfolio, designed to provide personnel protection against electrical shock in residential, commercial, and industrial environments. Hubbell GFCI receptacles are engineered to meet stringent safety standards, including UL 943 and CSA C22.2 No. 144.1, and are available in configurations that comply with National Electrical Code (NEC) requirements for ground-fault protection in wet or damp locations. The product family includes duplex and decorator-style receptacles in 15 A and 20 A ratings at 125 V AC, with NEMA configurations 5-15R and 5-20R. Many models feature weather-resistant (WR) and tamper-resistant (TR) constructions, as well as hospital-grade listings (UL 498 and CSA) for healthcare facilities. Hubbell GFCI receptacles are available in multiple colors—black, white, ivory, brown, and gray—and include both standard and self-test versions that automatically verify the GFCI circuit integrity. The line also encompasses surge-protected GFCI receptacles that combine ground-fault protection with transient voltage surge suppression. 3G Electric stocks over 115 SKUs of Hubbell GFCI receptacles, covering a broad range of voltage, amperage, and environmental specifications. This inventory supports applications from general-purpose indoor use to outdoor and industrial settings where moisture, dust, or corrosive atmospheres are present. The receptacles are built with corrosion-resistant metal components, impact-resistant thermoplastic faceplates, and sealed construction for wet locations (IP54 or higher where specified). For plant engineers and maintenance managers, Hubbell GFCI receptacles offer reliable ground-fault sensing with trip thresholds typically at 4–6 mA, ensuring rapid disconnection in fault conditions. Procurement specialists can source these devices through 3G Electric for projects requiring compliance with OSHA, NFPA 70E, or local electrical codes. The availability of multiple form factors—including duplex, decorator, and hospital-grade—allows specification matching for panel schedules, equipment circuits, and temporary power installations. 3G Electric provides global shipping and technical support for Hubbell GFCI products, ensuring that buyers receive authentic, code-compliant devices for their specific application requirements.

Frequently asked questions

Common questions about HUBBELL GFCI from 3G Electric.

What is the difference between Hubbell GFCI models GFR82BLK and GFR82W?

The primary difference is color: GFR82BLK is black, and GFR82W is white. Both are hospital-grade, duplex, 5-15R receptacles rated 125 V AC, 15 A, 2-pole/3-wire with GFCI protection. They share the same electrical specifications and are UL listed for hospital use. Choose based on aesthetic or code requirements for color coding in healthcare or industrial settings.

Are Hubbell GFCI receptacles suitable for outdoor use in Singapore's tropical climate?

Yes, many Hubbell GFCI models are weather-resistant (WR) and designed for wet locations. For example, the GFRTW20I is a weather-resistant duplex 5-20R receptacle. These units feature corrosion-resistant materials and sealed construction to withstand humidity and rain. Always verify the specific model's IP rating or WR marking on the product label to ensure compliance with local electrical regulations.

How do I select between a 15 A and 20 A Hubbell GFCI receptacle?

Select the amperage based on the circuit breaker rating and the connected load. A 15 A receptacle (e.g., GFR82W) is for 15 A circuits, while a 20 A receptacle (e.g., GFR20BLK) is for 20 A circuits. The NEMA configuration differs: 5-15R for 15 A, 5-20R for 20 A. Using a 20 A receptacle on a 15 A circuit is permissible if the load does not exceed 15 A, but the reverse is not code-compliant.

What is the self-test feature on Hubbell GFCI receptacles?

Self-test GFCI receptacles, such as the SNAPGF15W, automatically perform a diagnostic test every few seconds to verify that the ground-fault protection circuitry is functional. If the test fails, the receptacle trips and may indicate a fault via a visual indicator. This feature ensures continuous protection without manual testing, which is critical for industrial and healthcare environments where regular testing may be overlooked.

Can Hubbell GFCI receptacles be used in hospital-grade applications?

Yes, models like GFR82BLK and GFR82W are specifically listed as hospital grade. They meet UL 498 and CSA requirements for extra durability, impact resistance, and retention force. These are suitable for patient care areas, operating rooms, and other healthcare settings where ground-fault protection and reliability are mandatory under NFPA 99.

What is the typical trip threshold for Hubbell GFCI receptacles?

Hubbell GFCI receptacles are designed to trip when a ground-fault current of 4–6 mA is detected, in accordance with UL 943. This threshold provides personnel protection by disconnecting power within 25 milliseconds, reducing the risk of electrocution. The exact trip level may vary slightly by model but remains within the standard range.
