Quick Summary
ENRX-GFCI kit provides reliable ground-fault protection for hazardous-area electrical installations. In hostile environments, moisture, dust, and vibration trigger nuisance trips and complicate compliance, making robust protection essential. This unit carries NEC/CEC certifications, IP66 ingress protection, and a NEMA 4X enclosure, with hazardous-location ratings including Class I, Division 2 and Zone 2, plus Class II Division 1 and Class III suitability. The two-gang, through-feed design in copper-free aluminum simplifies panel layouts, reduces wiring complexity, and accelerates installation in tight spaces. Designed for a 3/4" trade size with 5-20R receptacles and 125 Vac operation, it supports reliable, long-life operation in demanding facilities while helping minimize total cost of ownership.

FAQs
Installers should mount the unit in a two-gang through-feed enclosure using copper-free aluminum hardware. Ensure a 3/4" trade size knockout is correctly sized and wired to a 5-20R receptacle. Verify NEC/CEC compliance and confirm Class I, Division 2 or Zone 2 suitability. Use proper torque on conductors, route wiring to minimize strain, and seal all access points to maintain IP66 protection.
The ENRCX22201 GFI carries NEC/CEC standards, IP66 ingress protection, and NEMA 4X enclosure. It is rated for Hazardous/Classified Locations with Class I, Division 2; Zone 2; Class II, Division 1; and Class III. These certifications confirm suitability for corrosive environments, moisture exposure, and strict safety requirements in industrial and marine settings.
Yes. The ENRCX22201 GFI is designed as part of the Ark-Gard ENRX family, supporting modular, through-feed configurations in two-gang enclosures. It integrates with Ark-Gard GFCI kits and related hazardous-area protection devices, simplifying installation in panels that require consistent, code-compliant ground-fault protection across multiple compartments.
The kit reduces downtime from nuisance trips due to robust 5 mA ground-trip and reliable 125 Vac operation, improving overall process uptime. Its rugged copper-free aluminum enclosure resists corrosion, lowering maintenance costs in harsh environments. Standardized two-gang through-feed installation also reduces labor time during commissioning and future panel upgrades, delivering a favorable total cost of ownership over the equipment lifetime.
Common scenarios include hazardous-location panels in chemical plants or offshore facilities. If trips occur, verify proper wiring to the 5-20R receptacle, confirm 125 Vac supply integrity, and check for moisture ingress or dust ingress at enclosure seals. Ensure the ground fault trip current is set to 5 mA, inspect for damaged conductors, and confirm enclosure integrity to maintain IP66 performance.
