Eaton 5266NCR Plug - Corrosion Resistant 15A/125V, cULus
Part Number: 5266NCR
Quick Summary
Eaton 5266NCR corrosion resistant straight blade plug provides reliable, plug-in connectivity for industrial equipment. In harsh environments, corrosion and wire fatigue can cause outages and expensive downtime, so a rugged, long-life solution is essential. This plug combines a heavy-duty industrial specification grade with a nylon body that stands up to corrosive conditions, RoHS compliance, and cULus safety certification for peace of mind across supply chains. It supports back-wire wiring with #18-12 AWG conductors, 15A at 125V, and a two-pole, three-wire grounding configuration for standard 5-15P applications. The yellow color enhances visibility in cluttered electrical zones, while the 14 lbf-in torque rating promotes consistent, secure terminations. These attributes translate to lower maintenance costs and improved equipment uptime.

FAQs
The 5266NCR uses back-wire wiring with #18-12 AWG conductors and accepts three wires in a two-pole, three-wire grounding configuration. It features screw terminals and a torque rating of 14 lbf-in to ensure secure terminations. This makes field installations straightforward and compliant with standard 5-15P equipment.
The plug uses a nylon body with corrosion-resistant properties, designed to withstand caustic or humid industrial environments. This reduces maintenance downtime, extends service life, and lowers total cost of ownership by minimizing frequent replacements in harsh plants.
Yes. It is a NEMA 5-15P configured plug intended for industrial applications, with a two-pole, three-wire grounding arrangement. Its back-wire option and screw connections support common equipment and receptacles, simplifying integration into existing power chains.
The 5266NCR is RoHS compliant and cULus Listed, with Federal Specification Classification 6221 02. These certifications confirm safety, regulatory compliance, and suitability for procurement in regulated industries, reducing risk in audits and supplier qualification processes.
By combining corrosion resistance, a durable nylon body, and reliable back-wire terminations, the plug minimizes downtime and maintenance costs. Its 15A/125V rating aligns with typical industrial loads, reducing the need for over-specification, while clear color coding and secure screw terminations lower installation errors and lifecycle expenses.
