Cooper Wiring Devices COOP7310-B – Frequently Asked Questions

1) What is the difference between the Cooper 7310-B and 7410-B locking receptacles?
Pole count and voltage. The 7310-B is the 3-pole version rated 125/250 volts; the 7410-B is the 4-pole version rated 120/208 volts. Both are 20A non-NEMA locking singles in black glass-filled nylon. Pick the one that matches your circuit: single-phase 125/250 three-pole, or three-phase 120/208 four-pole.
2) Will a standard NEMA twist-lock plug like an L14-20P fit the Cooper 7310B receptacle?
No. The 7310B is a non-NEMA locking configuration, so it only mates with the matching Cooper industrial locking plug of the same configuration. Standard NEMA L-series plugs will not engage it. If you need a NEMA-configured device, this is the wrong part.
3) Will the 4-pole 7410-B work on a 125/250V single-phase circuit?
No. The 4-pole 7410-B is rated 120/208 volts; the 125/250 volt version is the 3-pole 7310-B. Order by the system you're feeding, because the pole count and voltage are paired on these two.
4) Can the Cooper 7310B be used in a hazardous or explosionproof location instead of an Appleton device?
The Cooper 7310B is an industrial-application locking receptacle in a glass-filled nylon housing; it is not an explosionproof device. For classified areas, the Appleton FSQC series interlocked explosionproof receptacle is the device built for that duty, and the Appleton U-Line ECS factory-sealed 15 and 20 amp plug and receptacle set covers factory-sealed 3-pole connections at a comparable amperage.
5) What is the closest alternative to the Cooper 7310B locking receptacle if the circuit is 30A instead of 20A?
The Cooper Wiring Devices 7310B is rated 20A in a single, non-NEMA locking configuration. For a 30A non-NEMA locking single receptacle, the Pass & Seymour Turnlok 30A non-NEMA single receptacle covers that amperage in the same twist-lock, non-NEMA single-outlet format.
6) Is the Bryant 21254IGO a substitute for the Cooper 7310B?
No. The Bryant 21254IGO is a quad straight-blade receptacle in NEMA 5-20R at 20A, so a cord cap simply pushes in and pulls out. The Cooper 7310B is a non-NEMA locking device that mates only with the corresponding twist-lock plug, and it is a single outlet rather than four. They share only the 20A rating.
7) What should I specify instead of the Cooper 7310B for a 277V motor circuit?
The Cooper 7310B is offered at 120/208 volts or 125/250 volts, so a 277V circuit falls outside it. The Bryant 430R9W, a 4750DR series 2-pole 3-wire 277V motor-duty receptacle, is the device aimed at 277V motor duty, and the Pass & Seymour 5762 is a 15A 277V self-grounding duplex in specification grade.
8) I need 4-pole 120/208V locking power. Does the Cooper 7310B family cover it, or do I need another brand?
It is covered within the Cooper family: the 7410-B is the 4-pole, 120/208 volt version, and the 7310-B is the 3-pole, 125/250 volt version, both 20A non-NEMA locking. Among the other locking options, the Pass & Seymour Turnlok non-NEMA single is a 30A device and the Eaton 7379 is 50A at 600V/250V, so neither matches a 20A 4-pole requirement.
9) What wire size can I land on this Cooper industrial locking receptacle?
It accepts #14 through #8 AWG conductors, which covers a 20A branch circuit on #12 with plenty of room for upsized runs on long feeds. Terminals take back or side wiring, so you can land straight-in or wrap the screws depending on how tight the box is.
10) Can I use the 7310B on a 20A receptacle circuit in a plant where equipment gets unplugged constantly?
That's what it's built for. The twist-lock engagement keeps cords from being pulled out under vibration or foot traffic, the body is glass-filled nylon for impact resistance, and the device is rated industrial application at 20A. It's a single receptacle, so it's intended for one dedicated machine or cord drop rather than two loads off one yoke.
11) I need a 30A or 50A locking receptacle instead of 20A - what else is available?
The Cooper 7310B tops out at 20A. For 30A in a non-NEMA locking single, the Pass & Seymour Turnlok 30A non-NEMA single receptacle is the equivalent step up. For higher current, the Eaton industrial locking receptacle rated 50A, 600V/250V AC/DC is an extra heavy duty option in black.
12) Is a locking receptacle the right choice, or should I just use a heavy-duty straight-blade 20A device?
Use the locking type when the cord must not come loose: machine drops, portable equipment, anything subject to vibration or pull. It does require a mating locking plug on the cord, so if the equipment already has a straight-blade cord cap, a locking device means re-terminating. For straight-blade 20A/125V work, the Bryant 5362B heavy-duty duplex or the Pass & Seymour IG5362-I spec-grade isolated ground duplex cover that instead.
13) If I do not need a twist-lock connection, what 20A industrial receptacle can I use in place of the Cooper 7310B?
For a straight-blade 20A/125V device, the Bryant 5362B heavy-duty duplex receptacle gives you two standard outlets in a heavy-duty grade, and the Pass & Seymour IG5362-I is a heavy-duty spec-grade 20A 125V duplex with an isolated ground for sensitive equipment. The Cooper 7310B differs in that it is a single, non-NEMA locking outlet offered at 120/208 or 125/250 volts.
14) How does the Cooper 7310B compare with a single industrial spec-grade receptacle like the Eaton 6450W?
Both are single-outlet industrial devices, but the Eaton 6450W is an industrial specification grade decorator single receptacle accepting #14-10 AWG. The Cooper 7310B is a non-NEMA locking single that accepts a wider #14-8 AWG range and wires from the back or the side.
15) Is a 15A commercial-grade single receptacle an acceptable swap for the Cooper 7310B?
Not for the same circuit. The Eaton 816W commercial specification grade single receptacle is rated 15A, while the Cooper 7310B is rated 20A and uses a non-NEMA locking face rather than a blade configuration. The Eaton 5262W, a heavy-duty industrial 15A 125V 5-15R duplex in gray, is likewise a 15A straight-blade device.
16) Does the 7310B come with a cover plate or a mating plug?
The 7310B is sold as the receptacle device itself. The mating industrial locking plug and any cover plate or box are ordered separately, so plan on both when you spec the drop. Note the finish is black, so match your plate accordingly.
17) For a dedicated plug-load circuit with scheduled shutoff, is there an alternative to the Cooper 7310B?
The Pass & Seymour PLT26351 is a heavy duty spec grade plug load timer receptacle at 20A 125V, which adds timed control at the outlet. The Cooper 7310B is a non-switched, non-NEMA locking single receptacle for 120/208 or 125/250 volt industrial circuits, so the two serve different jobs at the same 20A rating.
18) What is the difference between the Cooper 7310B and the Bryant 5362BI?
The Bryant 5362BI is a 20A/125V heavy-duty duplex receptacle, giving two straight-blade outlets on one circuit. The Cooper 7310B is a single black non-NEMA locking receptacle with a glass-filled nylon body for industrial use. Same amperage, different connection method and outlet count.
