Quick Summary

Eaton CS8164EX Locking Connector is a rugged device designed for reliable industrial power distribution in California-standard environments. When connectors loosen under vibration or thermal cycling, downtime and safety risks rise; this locking design provides a positive, secure engagement that reduces maintenance and rework. It carries cULus Listed and CSA certified marks, along with California standard conformance, helping you meet stringent regulatory requirements in critical facilities. The rugged nylon housing with Pro grip, back-wire terminations, and a 50 A, 480 V rating supports demanding three-phase applications while simplifying installation for technicians. In practice, this translates to fewer field failures, faster panel builds, and lower lifecycle costs. The CS8164EX also aligns with non-NEMA configurations for flexible industrial layouts and long-term reliability.

FAQs

Begin by verifying the panel is rated for 480 V three-phase service and that the conductors are within #10-4 AWG. Route wires to the back-wiring terminals, secure each conductor under the appropriate screw, then align the connector body with the mating half and rotate the lock until it positively seats. Check torque and insulation integrity after installation to ensure long-term reliability.
The CS8164EX is rated 50 A at 480 V with three poles and four wires, designed for non-NEMA configurations. Its locking mechanism prevents accidental disconnection in vibration-heavy environments, while the nylon Pro grip and back-wire terminations streamline installation and reduce contact resistance. This combination supports reliable, high-load three-phase power delivery in industrial facilities.
Yes. The CS8164EX supports #10-4 AWG conductors and uses a back-wiring method for secure, clamp-free terminations. This simplifies field terminations, reduces torque variability, and speeds up wiring in control panels. Ensure conductors meet insulation and temperature ratings and that they are inserted fully to maintain a consistent electrical connection.
The CS8164EX is cULus Listed and CSA certified, reflecting compliance with recognized safety standards. This certification supports regulatory approvals for industrial facilities and helps reduce qualification time during procurement. In addition, the California standard conformance reinforces regional compliance, enabling smoother installation in state-mpecified electrical environments.
Expect lower maintenance due to the locking mechanism that prevents unintended disconnections and reduces re-entry events. The rugged nylon body and back-wiring approach simplify field service and terminations, shortening downtime for panel servicing. Over the lifecycle, you typically see reduced labor costs, fewer component replacements, and more consistent electrical performance in demanding industrial applications.
