FAQs
Installation begins with selecting an appropriate single-gang enclosure rated for Hazardous/Classified Locations, then mounting the ENRC21201 in a through-feed configuration. Use copper-free aluminum housing hardware, seal entry points to maintain NEMA protection, and route 3/4 inch trade-size conductors to the 5-20R receptacle. Verify NEC/CEC compliance and conduct a final functional test after wiring to ensure stable operation in Class I/II/III zones.
Yes. ENRC21201 is designed for Hazardous/Classified Locations and complies with NEC/CEC standards. It features Class I Division 1 and Division 2, Class II Division 1 and 2, and Class III ratings, with NEMA protections 3, 7, 9, and 12. UL certification references are available in the installation and certification documents, ensuring regulatory alignment for North American applications.
Ideal for oil and gas, chemical processing, mining, and offshore platforms, ENRC21201 supports 125 Vac, 20 A circuits in hazardous locations. Its through-feed design, single-gang format, and 50–400 Hz compatibility suit control panels, power distribution blocks, and receptacle points inside explosion-proof enclosures, delivering reliable performance in harsh environments.
Key features include a copper-free aluminum housing for corrosion resistance, 3/4" tradesize through-feed ports for straightforward wiring, and a 5-20R NEMA configuration for quick plug-in connections. These aspects minimize field wiring errors, shorten commissioning, and reduce maintenance cycles by improving durability and ease of replacement in tough environments.
The combination of NEC/CEC compliance, rugged copper-free aluminum construction, and a through-feed, single-gang format reduces downtime, lowers lifecycle maintenance costs, and minimizes compliance-related rework. Its durability in Class I–III locations and NEMA protection minimizes replacement frequency, delivering a favorable total cost of ownership for OEMs and maintenance teams.
