50 A 250 V straight-blade plug

This Hubbell CS8364C is a 50 A, 250 V AC straight-blade plug rated for three-phase industrial use. It has a 3-pole, 4-wire non-NEMA locking configuration built with Super Tough Nylon in a black-and-white housing. The non-shrouded body accepts cord diameters from .750 in to 1.125 in. It is intended for installers wiring heavy-duty equipment.

Check voltage, phase and cord size

Verify that the supply is 250 V AC three-phase and that the existing receptacle matches the 3-pole, 4-wire non-NEMA locking pattern. Confirm the cable outer diameter falls within the .750 in to 1.125 in range so the strain relief seals correctly. This plug does not suit single-phase or NEMA-configured outlets.

Industrial-grade nylon housing

The Super Tough Nylon shell resists impact and chemical exposure in harsh environments. No power indicator, corrosion-resistant coating or antimicrobial additive is fitted. The accessory set is limited to the plug body itself; no wiring tools, seals or adapters are bundled.

Questions about this item

Does the CS8364C include the cord or must I supply my own cable?

The plug is sold alone; you must provide a cord with an outer diameter between .750 in and 1.125 in that matches the 3-pole 4-wire 50 A 250 V rating.

How do I know whether the CS8364C matches my 50 A 250 V three-phase outlet?

It is a non-NEMA locking connector rated 50 A, 250 V AC, 3-pole 4-wire, designed for industrial three-phase service.

What does the 50 A 250 V rating mean when the plug is wired into my equipment?

It means the connector can continuously carry 50 amperes per pole at 250 volts AC in a three-phase circuit when installed with correctly sized conductors.
