Eaton Specification Sheet - 2839-BOX
Armored vinyl construction delivers rugged durability and resistance to daily wear in busy industrial spaces, reducing downtime and maintenance costs while preserving electrical integrity in harsh environments. The brass contact material ensures low contact resistance and dependable current transfer, supporting stable performance at the 15A/277V rating and improving overall system efficiency in commercial applications such as control panels and enclosures. Back-wire termination paired with a secure screw connection streamlines installation, minimizes wiring errors, and accelerates panel builds for faster project turnover. With a 0.25-0.63" cord range and #18-12 AWG compatibility, it accommodates common field wiring practices, enabling rapid field terminations without special tools. ED Box packaging aids inventory control and on-site logistics, while RoHS and cULus certifications provide regulatory confidence for facility uptime and maintenance programs. The NEMA 7-15P configuration supports grounding, enhancing safety in grounded setups and reducing fault risk in busy electrical rooms. In practice, the combination of armor, material choice, and verified certifications translates to lower lifecycle costs and higher reliability in commercial wiring scenarios.

FAQs
The 2839-BOX uses a back-wire termination combined with a standard screw connection, enabling quick, secure field wiring for #18-12 AWG conductors. With a 15 lbf-in torque rating and clear terminal access, technicians can achieve reliable terminations without specialized tools, reducing installation time and minimizing the risk of loose connections that could cause overheating or nuisance trips.
Yes. The model is specified for 15A at 277V and features a NEMA 7-15P two-pole, three-wire grounding receptacle. This aligns with common commercial equipment and lighting loads, providing a safe, code-compliant connection for fixed-wiring installations in offices, retail spaces, and industrial facilities.
Durability comes from the armored vinyl face and body, brass contacts, and a robust ED Box packaging. The armored construction withstands mechanical wear, tight enclosure environments, and routine maintenance handling, while brass contacts ensure enduring low-resistance connections. The design minimizes downtime due to wear, corrosion, or loose wiring in maintenance-heavy areas.
The 2839-BOX is RoHS compliant and cULus listed (Federal Specification Classification 6221 02). These certifications indicate restricted hazardous substances and compliance with recognized safety standards, respectively. For facilities, this translates to regulatory assurance, safer maintenance practices, and smoother inspections for electrical installations in commercial spaces.
Absolutely. The unit supports #18-12 AWG conductors with a 0.25-0.63 inch cord range and features an armored vinyl face, making it well-suited for armored cable runs in commercial settings. Its 15A/277V rating and secure back-wire with screw termination further ensure reliable, code-compliant connections in busy electrical rooms.
