Through-feed construction simplifies field wiring by reducing penetrations and alignment errors. This translates to faster installs, lower commissioning time, and fewer miswiring faults in the panel, especially when working in hazardous locations where mistakes carry safety and downtime costs. Copper-free aluminum enclosure delivers corrosion resistance without the weight of traditional materials. The result is lower maintenance needs and easier handling during deployment in marine or chemical-processing environments, with shipping and installation savings. 15A at 125 VAC and a broad 50-400 Hz frequency range ensure compatibility with standard control circuits and variable power sources. This cross-compatibility reduces stocking complexity for integrators and minimizes the need for adapters. NEMA configuration 5-15R and single-gang through-feed design offer a familiar plug interface and straightforward mounting in control panels. Coupled with a 3/4 in trade size, installers can align with common conduit and enclosure layouts with predictable fit. Compliance with NEC/CEC in hazardous/classified locations and a NEMA rating of 3, 7, 9, 12 provide regulatory confidence and safety margins for industrial, marine, and offshore installations. Compact footprint and light weight—8 in length, 6.72 in height, 3.5 in width, and about 1 lb—facilitate panel density optimization and easier handling at job sites. As part of Ark-Gard ENR Value, the ENRC21151 supports quick interchange with other Ark-Gard components and offers through-feed versatility for through-box wiring configurations.

FAQs
The ENRC21151 is a single-gang through-feed receptacle with a 3/4" trade thread, designed for copper-free aluminum housings. It accepts 125 VAC supplies up to 15 A and supports 50-400 Hz, aligning with standard panel and conduit configurations used in Class I/II/III locations. Its compact 8 in length and 6.72 in height simplify panel layout, while the through-feed design reduces field wiring steps and misalignment.
ENRC21151 carries NEC/CEC standards for hazardous/classified locations, with NEC hazardous ratings covering Class I Division 1 and 2, Class II Division 1 and 2, and Class III. The unit also carries a NEMA rating of 3, 7, 9, and 12, providing broad environmental protection and safety assurances for industrial installations.
Yes. The copper-free aluminum construction offers improved corrosion resistance essential for marine and offshore environments. Coupled with Ark-Gard ENR Value design, the receptacle assembly withstands washdowns and challenging exposure while maintaining ease of installation and reduced maintenance over time.
Ark-Gard ENR Value delivers reliable interconnection with common NEMA plugs, through-feed wiring for straightforward field connections, and a lightweight footprint that saves panel space and lowers shipping and warehousing costs. These features translate to faster builds, fewer field errors, and predictable performance for panel builders and maintenance teams.
The combination of corrosion-resistant copper-free aluminum, reduced installation time from through-feed wiring, and regulatory compliance (NEC/CEC, NEMA 3/7/9/12) lowers maintenance costs, minimizes downtime, and simplifies inventory. For projects in hazardous locations, these factors collectively contribute to a faster return on investment and lower lifecycle costs.
