Cooper Wiring Devices CS8469 – Frequently Asked Questions

1) Will a standard NEMA twist-lock plug fit the Cooper CS8469 receptacle?
No. The CS8469 uses a Non-NEMA locking pattern built to California standard requirements, so NEMA L-series plugs (L6-50, L8-20 and the like) will not mate with it. You need the matching California-standard plug for this 480V, 50A two-pole three-wire pattern. If your cord set is NEMA-patterned, this is the wrong receptacle for the job.
2) What size conductors can I land in the Cooper CS8469 50A locking receptacle?
Terminals take #10 through #6 AWG, and it is a back-wired device, so the conductors land into the back of the body rather than under side screws. For a 50A circuit that range comfortably covers the usual #6 copper feed, and it also lets you terminate a larger-than-minimum conductor if the run length pushed you up a size.
3) Is the CS8469 two-pole three-wire receptacle suitable for a 480V three-phase load?
It is a two-pole, three-wire device: two current-carrying poles plus a ground. That suits 480V single-phase or a two-leg feed, not a three-phase load, which needs three poles plus ground (three-pole four-wire). If the machine nameplate calls for 480V three-phase, this is not the receptacle.
4) I need a 50A locking receptacle but my system is 600V, not 480V. What else is there?
The CS8469 is rated 480V, so do not use it above that. Eaton's industrial locking receptacle 7379 is a 50A device rated 600V/250V AC/DC and is built extra heavy duty, which covers the higher-voltage case at the same amperage.
5) What should I use instead of the Cooper CS8469 in a hazardous or classified area?
The Cooper CS8469 is a steel-body industrial locking receptacle and is not an explosionproof device. For classified locations, the Appleton FSQC series interlocked explosionproof receptacle is the alternative, and the Appleton U-Line ECS factory-sealed plug and receptacle set covers factory-sealed 15 and 20 amp three-pole connections. Those Appleton devices are at lower amperage than the 50A Cooper, so verify the load.
6) What is the closest alternative to the Cooper CS8469 locking receptacle for a 50A industrial circuit?
The Eaton 7379 industrial locking receptacle is the nearest peer: it is also rated 50A and is also a black locking device, listed at 600V/250V AC/DC and as extra heavy duty. The Cooper CS8469 is rated 480V at 50A in a two-pole, three-wire arrangement with a Non-NEMA pattern. Confirm the blade pattern of the mating plug before choosing between them, since the voltage classes differ.
7) Why use a locking receptacle instead of a straight-blade one on industrial equipment?
A twist-lock connection holds the plug mechanically, so vibration from motors and machinery will not walk the cord out of the outlet. That is the whole reason the CS8469 exists at 480V and 50A, where an accidental disconnect under load is a safety event. Straight-blade devices like the Bryant 21254IGO 20A 5-20R quad are for convenience power on cord-and-plug loads, not for equipment feeds at this voltage.
8) Is there a smaller Non-NEMA locking receptacle if 50A is more than my circuit needs?
Yes. The Pass & Seymour Turnlok 30A Non-NEMA single receptacle is a lower-amperage option in the same Non-NEMA locking family if your branch circuit is 30A rather than the 50A the Cooper CS8469 is rated for. Match the plug pattern on your cord set either way, since Non-NEMA patterns are not interchangeable between lines.
9) Can I use a standard duplex receptacle such as the Bryant 5362B instead of the Cooper CS8469?
No. The Bryant 5362B is a heavy-duty 20A/125V duplex receptacle for ordinary straight-blade cords, while the Cooper CS8469 is a 480V/50A two-pole, three-wire locking device wired at the back for #10-6 AWG conductors. The voltage class, amperage and blade pattern are all different, so the two are not interchangeable on the same circuit.
10) What is the Cooper CS8469 housing made of, and will it hold up in a plant environment?
The body is steel, in black, which is why it gets specified for industrial power circuits rather than a thermoplastic commercial device. Steel adds mechanical strength where the receptacle is exposed to impact and heavy cord handling.
11) How many outlets does the Cooper CS8469 have?
It is a single-outlet device, one locking receptacle per body, which is standard for a 50A equipment feed. If you need two outlets on one strap for 120V convenience loads, that is a duplex device like the Bryant 5362B 20A/125V heavy-duty duplex, not this one.
12) What is the exact part number for the Cooper 480V 50A locking receptacle?
Cooper Wiring Devices CS8469. That is the number to quote for the steel-body, black, Non-NEMA California-standard locking receptacle rated 480V at 50A, two-pole three-wire.
13) Is an industrial specification grade receptacle like the Eaton 5262W an equivalent to the Cooper CS8469?
They serve different circuits. The Eaton Arrow Hart 5262W is an industrial specification grade duplex receptacle rated 15A 125V in a 5-15R straight-blade pattern, suited to general tool and cord loads. The Cooper CS8469 is a 480V/50A two-pole, three-wire locking receptacle for heavy equipment feeds. Use the Eaton for standard 125V outlets and the Cooper where a twist-lock 480V connection is specified.
