Cooper Wiring Devices 7314-C – Frequently Asked Questions

1) Will a standard NEMA L14-20 or twist-lock plug fit the Cooper 7314-C receptacle?
No. The Cooper Wiring Devices 7314-C is a Non-NEMA configuration, so it only mates with the matching Cooper safety grip locking plug for that configuration. A NEMA-configured twist-lock plug will not engage it even if the amperage and voltage look right. If your equipment cord ends in a standard NEMA locking plug, you need a NEMA device instead, not this one.
2) Can I use this 20A 125/250V receptacle on a 240V machine circuit?
It is rated 20A at 125/250V, three-pole three-wire, so it suits a 250V class two-hot circuit or a 125/250V feed within that 20 amp limit. Three-wire with three poles means there is no separate equipment grounding conductor in the device count, so plan your grounding path accordingly on the machine side. Do not put it on a circuit protected above 20 amps.
3) I need a non-NEMA locking receptacle but my load draws more than 20 amps. What are my options?
The Cooper 7314-C tops out at 20A. For a larger non-NEMA locking device, the Pass & Seymour Turnlok 30A non-NEMA single receptacle covers 30 amps. Higher still, the Eaton 7379 industrial locking receptacle is rated 50A at 600V/250V AC/DC. Match the device to the matching plug family in each case, since non-NEMA configurations are not interchangeable between manufacturers.
4) We need a hazardous-location receptacle, not just an industrial one. What replaces the Cooper 7314-C?
The Cooper 7314-C is an industrial nylon locking receptacle but is not a hazardous-location device. For classified areas, the Appleton FSQC Series interlocked explosionproof receptacle is the alternative, and the Appleton U-Line ECS factory-sealed 15 and 20 amp plug and receptacle set covers a 3-pole connection in a factory-sealed design that matches the 7314-C's amperage range.
5) Can I use a standard 20A duplex receptacle in place of the Cooper 7314-C?
No. The Cooper 7314-C is a locking device with a safety grip design and a non-NEMA three-pole, three-wire configuration, so it only mates with the matching industrial locking plug. Straight-blade 20A devices such as the Bryant 5362B heavy-duty 20A/125V duplex or the Pass & Seymour IG5362-I heavy-duty spec-grade isolated ground duplex accept cord caps with blades and will not hold a locking plug.
6) What is the closest non-NEMA locking receptacle to the Cooper 7314-C from another brand?
The Pass & Seymour Turnlok 3330 is the nearest counterpart in a different brand: it is also a non-NEMA single locking receptacle, rated 30A. The Cooper 7314-C is rated 20A at 125/250V in a three-pole, three-wire configuration, so the two are not interchangeable by rating - confirm the amperage your circuit and mating plug require before substituting the 30A Turnlok.
7) If I need a higher-amperage industrial locking receptacle instead of the Cooper 7314-C, what should I look at?
The Eaton 7379 industrial locking receptacle is rated 50A at 600V/250V AC/DC in an extra heavy duty grade and comes in black. The Cooper 7314-C is the 20A, 125/250V device in gray. Step up to the 50A Eaton only if the mating plug and feeder are sized for it.
8) Is a locking receptacle worth it over a straight-blade 20A device on plant floor equipment?
On machinery that vibrates or on cords that get pulled, yes. The safety grip locking action holds the plug in place and resists working loose, which a straight-blade device cannot do. If the load is a bench tool or office equipment on a 125V circuit, a heavy-duty straight-blade like the Bryant 5362B 20A/125V duplex is the simpler choice. Pick the locking device where an accidental disconnect stops production or creates a hazard.
9) Is the Bryant 430R9W a substitute for the Cooper 7314-C on a motor circuit?
They are different devices. The Bryant 430R9W (4750DR series) is a 2-pole, 3-wire 277V motor-duty receptacle. The Cooper 7314-C is three-pole, three-wire at 125/250V, 20A. The pole count and voltage both differ, so the 430R9W will not accept the same plug or serve the same circuit.
10) For general plant floor outlets where a locking connection is not required, what is an alternative to the Cooper 7314-C?
Where a cord does not need to be locked in, the Eaton Arrow Hart heavy-duty industrial duplex receptacle is a 15A 125V 5-15R device in gray at industrial specification grade, and the Eaton 6450W is an industrial specification grade decorator single receptacle taking #14-10 AWG. The Cooper 7314-C is the choice when vibration resistance and a 125/250V three-pole locking connection are needed.
11) Will the nylon housing hold up in a manufacturing environment?
The body is molded nylon, which is what Cooper uses on industrial-grade devices for impact resistance and dimensional stability. It is an industrial application device, gray bodied so it reads differently from the standard commercial receptacles on the same wall. Nylon is not a sealed or explosionproof enclosure though, so it is not the part for hazardous classified areas.
12) How do I order the right part number for this Cooper safety grip locking receptacle?
Order by manufacturer part number 7314-C from Cooper Wiring Devices. There is one configuration: 20A, 125/250V, three-pole three-wire, non-NEMA, gray nylon. There are no finish or amperage variants to specify, so the part number alone identifies it.
13) What is the difference between the Cooper 7314-C and a commercial-grade single receptacle like the Eaton 816W?
The Eaton 816W is a commercial specification grade single receptacle rated 15A. The Cooper 7314-C is built for industrial use with a nylon housing, 20A at 125/250V, and a three-pole three-wire locking configuration. The 816W suits general commercial outlets; the 7314-C is for equipment hookups that need a secured connection at a higher amperage.
14) I need multiple 20A outlets in one box rather than one locking outlet. What is the option?
The Bryant 21254IGO is a quad straight-blade receptacle in NEMA 5-20R at 20A, giving four 20A outlets in one device. The Cooper 7314-C is a single non-NEMA locking receptacle at 20A, 125/250V, so it serves one locking plug rather than several cord caps.
