HUBBELL GFCI
Frequently asked questions
Common questions about HUBBELL GFCI from 3G Electric.
What is the difference between Hubbell GFCI hospital-grade and general-purpose receptacles?
Hubbell hospital-grade GFCI receptacles are tested to UL 498 and meet additional performance criteria for high-abuse environments, including higher impact resistance and a minimum 10,000-cycle endurance rating. General-purpose models meet the same safety standards but are intended for less demanding applications. Hospital-grade versions often feature a green dot on the face and are available in weather-resistant configurations. Both types provide ground-fault protection and are rated 125V AC at 15 A or 20 A.
Are Hubbell GFCI receptacles available in weather-resistant versions?
Yes, Hubbell offers weather-resistant GFCI receptacles designed for outdoor and wet locations. These models, such as the GFRTW83R and SNAPGFTW83R, feature a weather-resistant construction that includes corrosion-resistant components and a gasket to seal against moisture. They are rated for 125V AC at 20 A and are available in duplex and decorator duplex configurations. Weather-resistant GFCIs are suitable for applications such as outdoor lighting, pool areas, and construction sites.
What NEMA configurations are available in the Hubbell GFCI line?
The Hubbell GFCI line includes NEMA 5-15R and 5-20R configurations. The 5-15R is rated 15 A, while the 5-20R is rated 20 A. Both are 125V AC, 2-pole, 3-wire devices. These configurations are standard for North American electrical systems and are compatible with common plug types. The receptacles are available in duplex and decorator duplex styles, with various color options to match existing installations.
Do Hubbell GFCI receptacles include self-test functionality?
Many Hubbell GFCI receptacles include a self-test feature that automatically tests the device's ground-fault detection circuitry at regular intervals. This ensures continuous protection and alerts the user if the device fails to trip. The self-test function is typically indicated by an LED status light. Models with self-test are available in both general-purpose and hospital-grade versions. Refer to the specific model's datasheet for confirmation of this feature.
What is the voltage and amperage rating of Hubbell GFCI receptacles?
Hubbell GFCI receptacles are rated 125V AC and are available in 15 A and 20 A versions. The 15 A models use NEMA 5-15R configuration, while the 20 A models use NEMA 5-20R. All are 2-pole, 3-wire devices. These ratings are suitable for typical commercial and industrial branch circuits. The devices are designed to interrupt power when a ground fault is detected, protecting personnel from electrical shock.
Can Hubbell GFCI receptacles be used in food processing plants?
Yes, Hubbell GFCI receptacles are suitable for food processing plants where washdown and moisture are present. Weather-resistant and hospital-grade models offer additional protection against corrosion and physical abuse. The receptacles should be installed in accordance with local electrical codes and may require appropriate enclosures. The ground-fault protection helps prevent electrical shocks in wet environments, making them a common choice for areas with high humidity or frequent cleaning.
