Cooper Wiring Devices CS6364 – Frequently Asked Questions

1) Will the Cooper CS-6364 locking connector fit my cord? What cord diameter does it clamp?
The CS-6364 armored locking connector takes cord with an outside diameter from 0.68 to 1.13 inches, so it covers most heavy portable industrial cable in the 50A range. Conductors themselves must be #10 through #6 AWG. If your cord jacket measures under 0.68 inches the clamp won't grip it properly, and over 1.13 inches it won't close.
2) Is the Cooper CS-6364 a NEMA twist-lock? Will it mate with an L6-50 plug?
No. The CS-6364 is a Non-NEMA configuration built to the California standard pin pattern, not a NEMA twist-lock. It will not mate with an L-series NEMA plug. It only mates with California-standard (CS) devices of the same pole and voltage rating. If you need a true NEMA twist-lock, look at a NEMA-configured connector such as the Bryant 705 Series or the Eaton Arrow Hart Ultra-Grip L14-20.
3) Which CS-6364 version do I order for a 480 volt three-phase machine versus a 125/250 volt circuit?
Two combinations are offered. The 3-pole, 125/250 volt version is MPN CS6364. The 2-pole, 480 volt version is MPN CS8464. Match the pole count and voltage to the equipment you are feeding; the two are not interchangeable and will not mate with each other.
4) I need a 50 amp connector but my equipment uses a standard NEMA plug. What should I buy instead?
Then the CS-6364 is the wrong part, because it is a California-standard Non-NEMA device and will not accept a NEMA plug regardless of amperage. Buy a NEMA-configured locking connector matched to your plug's configuration: the Leviton industrial 4-wire 3-pole 125/250V connector and the Leviton 3-wire 2-pole L5-30R are examples of NEMA-pattern industrial grade devices, though both are rated below 50A, so confirm the amperage on the plug you are mating to.
5) What locking connector should I use if the cord cap on my equipment is a standard NEMA twist-lock instead of a California-style device?
The Cooper CS-6364 armored locking connector is a Non-NEMA configuration, so it will not mate with a standard NEMA twist-lock cord cap. For NEMA twist-lock openings, the Bryant 705 Series locking connector is offered in NEMA twist-lock configurations, and the Bryant 71020NC is a non-metallic NEMA locking connector in the 7 Series. Confirm the exact NEMA configuration letter and number on the mating device before ordering.
6) Is there a 30A locking connector alternative if 50A is more than my circuit needs?
The Cooper CS-6364 is rated 50A for #10-6 AWG conductors, which suits heavy equipment circuits. For a 30A circuit, the Eaton Arrow Hart Ultra Grip connector is a 30A two-pole three-wire nylon device in the L6-30 series, and the Leviton 2313 is a 30A 125V three-wire two-pole industrial grade connector in NEMA L5-30R. Match the device to the receptacle configuration and the breaker size on the branch circuit.
7) I need a four-pole locking connector. Does the Cooper CS-6364 cover that?
No. The Cooper CS-6364 armored locking connector is built in 2-pole and 3-pole versions only. If the equipment requires four poles, the Leviton 2323 is a 5-wire 4-pole industrial grade locking connector rated 20A. Check the amperage requirement as well, since the pole count and the current rating both have to match the equipment.
8) How do the terminals land on this 50A connector, and what size conductor can I get in?
Back wiring. Conductors terminate at the back of the device rather than under side screws, which keeps the terminations inside the armored shell. Allowable wire size is #10 to #6 AWG, which covers a 50A feed in copper at typical cord-and-plug sizing.
9) Is a steel armored connector worth it over a nylon or non-metallic body for a plant floor?
The CS-6364 uses an armored steel housing, which is the choice where the connector gets dropped, dragged, or struck, typical of machinery drops and harsh-environment industrial areas. Lighter non-metallic bodies, like the Bryant 71020NC non-metallic locking connector or Eaton's nylon Ultra Grip L6-30, are easier to handle and suit cleaner commercial locations, but they do not give you the same impact resistance.
10) What is the closest equivalent to the Cooper CS-6364 for a 125/250V three-pole four-wire application?
The Cooper CS-6364 is offered in a 3-pole 125/250 volt version with armored steel construction and 50A rating. The nearest peer for a 125/250V three-pole four-wire opening is the Leviton 2413 industrial locking connector, a 4-wire 3-pole 125/250V device. The difference is construction and current rating: the Cooper is steel and armored at 50A, so verify the ampacity your equipment draws before swapping.
11) Which locking connector is specified as extra heavy-duty industrial grade?
The Eaton 7506 is designated extra heavy-duty industrial specification grade and is an L1-15 configuration in black. The Cooper CS-6364 is an industrial-application armored steel connector built to California standard specifications at 50A, so the two are not interchangeable: the Eaton is an L1-15 NEMA device and the Cooper is Non-NEMA. Pick by the mating configuration first, then by grade language on your spec sheet.
12) Is the CS-6364 an industrial grade device or a commercial one?
Industrial. The application rating is industrial, with the steel armored shell and 50A capacity aimed at machinery feeds, power distribution, and heavy portable cord sets. Among comparable devices, the Eaton 7506 is an extra heavy-duty industrial specification grade connector and Eaton's Ultra-Grip L14-20 is commercial grade, so grade varies by product even within one brand.
13) Does the 2-pole 480 volt CS8464 have a ground?
Pole count and voltage are what the CS-6364 family is specified by: 2-pole at 480 volts (CS8464) and 3-pole at 125/250 volts (CS6364). Order by the pole and voltage combination that matches the mating device on your equipment, since California-standard patterns differ between those ratings and will not cross-mate.
14) Is there a commercial-grade locking connector option instead of a 50A industrial one?
Yes. The Eaton Arrow Hart Ultra-Grip L14-20 connector is a commercial grade device rated 20A at 125/250V. The Cooper CS-6364 is an industrial-application connector rated 50A with a 0.68 to 1.13 in cord diameter range for larger industrial cable. Choose the commercial 20A device for light generator and tool cord sets, and the 50A armored connector where the cord and load are heavier.
