FAQs
For ENRC21202, plan for a through-feed single-gang mounting in 3/4 inch trade size spaces, using the 6-20R NEMA configuration. Ensure panel openings and backboxes meet NEC/CEC requirements for Class I and II locations. Use copper-free aluminum to maximize corrosion resistance in damp or chemically aggressive environments and verify 50-400 Hz service to avoid resonance in variable-frequency systems.
ENRC21202 is designed for Hazardous/Classified Locations with NEC/CEC compliance and Class I, Division 1 & 2, Class II, Division 1 & 2, Class III ratings. It also carries NEMA ratings 3, 7, 9, and 12, ensuring enclosure integrity against dust, water ingress, and explosion hazards. This alignment supports regulatory approvals, safer installation, and longer service life in demanding environments.
Yes. The Ark-Gard ENR Value receptacle is purpose-built for hazardous-area and marine equipment environments. Its copper-free aluminum construction provides corrosion resistance, while its through-feed, single-gang design suits compact control panels common in offshore platforms, refineries, and chemical plants, delivering reliable power where space and safety are critical.
The device complies with NEC/CEC standards for hazardous locations and carries NEC hazardous ratings across Class I, II, and III. Its NEMA 3, 7, 9, 12 ratings further guarantee enclosure integrity under moisture, dust, and explosive atmospheres. This combination simplifies regulatory approvals and helps maintain code-compliant installations in diverse industrial settings.
Copper-free aluminum reduces corrosion and weight, translating to lower maintenance needs and easier handling during replacements. The through-feed design accelerates wiring and commissioning, shortening project timelines and reducing labor costs. Over the system lifetime, fewer failures in harsh environments contribute to improved uptime and total cost of ownership.
