Cooper Wiring Devices 1234-BOX – Frequently Asked Questions

1) Will this Cooper three-phase receptacle work with S42 plugs?
Yes, it is built for use with S42 devices and configurations. That is the mating system to verify first, because a power-style receptacle of this kind is not a NEMA straight-blade or locking pattern and will not accept a standard plug.
2) What do I use in place of this receptacle in a hazardous or classified area?
The Cooper Wiring Devices three-phase receptacle is a flush-mount glass-filled nylon device for general commercial and industrial interiors. For a classified location the Appleton FSQC Series interlocked explosionproof receptacle is the corresponding style, and the Appleton U-Line ECS factory-sealed 15 and 20 amp plug and receptacle set is a 3-pole factory-sealed option. Those are enclosure-based devices, so plan box and conduit sealing accordingly rather than a standard flush box.
3) If the load needs a locking connection instead of a straight-blade three-phase receptacle, what should I use?
The Cooper Wiring Devices three-phase power receptacle is a flush-mount power-style receptacle with screw terminals accepting #12 to 4 AWG, offered in 2-pole 250 volt, 3-pole 125/250 volt, and 4-pole 120/208 volt versions. Where the cord has to twist-lock so it cannot vibrate loose, the Eaton 7379 is an industrial locking receptacle rated 50A at 600V/250V AC/DC in black, and the Bryant 70520FR is a NEMA flanged locking receptacle from the 7 Series. Locking devices require a matching locking plug, so confirm the cap on the equipment cord before switching styles.
4) Can I use a heavy-duty duplex receptacle instead of this three-phase power receptacle for shop equipment?
Only if the equipment is single-phase 125 volt. The Cooper Wiring Devices receptacle is a three-phase device built for balanced three-phase loads. A 125 volt duplex such as the Bryant 5362B heavy-duty 20A/125V duplex, the Pass and Seymour 26352W 20A 125V specification grade decorator duplex, or the Eaton 5262W industrial specification grade 15A 125V 5-15R will serve hand tools and bench outlets, but none of them will carry a three-phase feeder. Match the device to the phase on the branch circuit, not to the amperage alone.
5) Is this Cooper receptacle a flush mount or does it need a surface box?
It is a flush-mount device, meant to sit in a standard electrical box or enclosure rather than on a surface-mounted housing. If your install is surface conduit on a machine shop wall, you will need an enclosure that accepts a flush device.
6) I need a locking receptacle instead of a three-phase power receptacle. What else is there?
If your equipment uses a twist-lock cord cap, this Cooper power receptacle is the wrong device type. Consider the Bryant 70520FR, a 7 Series NEMA flanged locking receptacle, the Eaton 7379 industrial locking receptacle rated 50A at 600V/250V AC/DC, or the Pass & Seymour Turnlok 30A non-NEMA single receptacle. Choose by the configuration on the existing plug, not just the amperage.
7) Can I use this for a standard 120V outlet in an office or apartment?
No. This is a three-phase power receptacle, not a general-purpose duplex. For ordinary 125 volt receptacles look at the Bryant 5362B heavy-duty 20A/125V duplex, the Pass & Seymour 26352W 20A 125V spec grade decorator duplex, or the Eaton Arrow Hart 15A 125V 5-15R industrial duplex.
8) I need a receptacle for a 277 volt motor connection, not a three-phase feeder. What fits?
The Bryant 430R9W is a 2-pole 3-wire 277V motor-duty receptacle in the 4750DR series, intended for that single-phase 277 volt motor connection. The Cooper Wiring Devices three-phase power receptacle covers 250 volt 2-pole, 125/250 volt 3-pole, and 120/208 volt 4-pole configurations instead, so pick by the voltage and pole count on the motor nameplate.
9) How durable is the housing on this receptacle for a plant floor?
The body is glass-filled nylon, which adds mechanical strength and impact resistance over standard thermoplastic, and it is finished in black. That construction is aimed at manufacturing, motor, and machine connection points where devices take knocks.
10) My conductors are #10 AWG on a general-purpose outlet, do I need this receptacle's wire range?
The Cooper Wiring Devices three-phase power receptacle takes #12 to 4 AWG at screw-back terminals, which is sized for feeder and larger branch conductors. For a lighter single-outlet job, the Eaton 6450W heavy-duty industrial specification grade decorator single receptacle accepts #14 to 10 AWG, and the Eaton 816W commercial specification grade single receptacle is a 15A single-outlet device. Choose based on the conductor size landing in the box and the phase of the circuit.
11) Does an ivory heavy-duty duplex like the Bryant 5362BI cover the same applications?
The Bryant 5362BI is a 20A/125V heavy-duty duplex receptacle, so it belongs on single-phase convenience circuits. The Cooper Wiring Devices receptacle is a black three-phase power receptacle in glass-filled nylon for motor, machinery, and equipment feeder connections. The overlap is limited to the same facility, not the same circuit.
