Locking connector · 50A 600 Vac/250 Vdc 3P4W non-NEMA Pro Grip nylon · Eaton 7764EX
Industrial grade locking connector rated 50A at 600 Vac and 250 Vdc for 3-pole, 4-wire grounding applications. Pro Grip nylon body with back wiring accepts #10-6 AWG conductors and cord diameters from 0.44 to 1.06 in (11.1 to 26.9 mm).
What this product is for
This locking connector is used to terminate portable power cable where a secure twist-lock style connection is required on 50A industrial circuits. It is intended for non-NEMA 3-pole, 4-wire grounding applications in industrial equipment, temporary power, and heavy-duty cord sets.
Use for
- 50A industrial cord ends on 600 Vac or 250 Vdc systems
- Portable equipment connections in plants, shops, and construction environments
- Replacement of existing California standard non-NEMA locking devices where matching configuration is required
Avoid for
- Standard NEMA locking configurations
- Applications requiring a receptacle, plug, or flanged inlet instead of a female cable connector
- Installations outside the listed wire and cord diameter range
Best for
Electricians and maintenance teams needing a field-wired 50A locking connector with a nylon Pro Grip body, back wiring, and support for larger portable cable sizes.
Installed in
Industrial facilities, OEM equipment connections, generator and temporary power assemblies, and maintenance cord sets. Commonly used where a locking connection helps reduce accidental disconnects under load handling conditions.
Why this product exists
This connector provides a secure cable-end termination for higher-amperage non-NEMA locking applications. Compared with straight-blade devices, the locking interface is typically chosen where vibration, movement, or frequent connection cycles make retention important.
Compared with similar products
Compared with armoured-body versions, this Pro Grip nylon model is lighter and suited to general industrial cord-end use. It is also a connector body, so it mates with the corresponding plug configuration rather than serving as the supply-side receptacle.
