Cooper Wiring Devices 8450N Three-Phase Power Receptacle, Brass

The Cooper Wiring Devices 8450N Single Three-Phase Power Receptacle is engineered for dependable power distribution in commercial and industrial electrical systems. This family is available in a range of voltage ratings from 125 volts through 250/250 combinations up to 277 volts, and in a choice of color finishes including Black, Brown, Gray, Ivory, Light Almond, Red, and White, so contractors can match the receptacle to both the electrical load and the surrounding device finish. Every option in this family shares the same core construction: durable brass contacts and secure screw-terminal connections, built for three-phase power applications where consistent conductivity and long-term performance matter. Its flush mounting design allows for a clean, low-profile installation in standard electrical boxes, making it a practical choice for professional electricians specifying reliable power receptacles for demanding job sites.

Cooper Wiring Devices 817LA-BOX – Frequently Asked Questions

1) Will the Cooper power receptacle mount in a standard flush electrical box?
Flush mounting, yes. It sets into a standard box for a low-profile finish rather than mounting on the surface in a box cover or an FS-type enclosure. If the install calls for a surface-mount device on exposed conduit, this is the wrong style and you want a box-cover or factory-sealed unit instead, such as the Appleton U-Line ECS plug and receptacle set.
2) Is this Cooper receptacle a three-phase device or a standard single-phase outlet?
It is built for three-phase power systems, which is what separates it from a general-purpose duplex outlet. It is a power-style receptacle for equipment and machinery connections, not for convenience receptacles on a general lighting and appliance branch circuit. If you are wiring a break room or a corridor, this is not the device you want.
3) Can I use this Cooper receptacle in a hazardous or classified area?
No. It is a flush-mount device for standard electrical boxes in commercial and industrial installations, with no explosionproof or factory-sealed construction. For a Class I or Class II classified location you need a purpose-built unit, such as the Appleton FSQC Series interlocked explosionproof receptacle. Do not substitute a general commercial device into a classified area.
4) Can a Cooper Wiring Devices flush-mount power receptacle be used in a classified hazardous location, or is an explosionproof device required?
The Cooper Wiring Devices single three-phase power receptacle is a flush-mounting receptacle with brass contacts and screw-terminal connections, built for standard commercial and industrial power distribution in ordinary locations. Where the area is classified and the wiring method has to contain an ignition, the device to specify instead is the Appleton FSQC Series interlocked explosionproof receptacle, which is built as an explosionproof interlocked device rather than a flush device set into a standard box. The interlock means the plug cannot be inserted or withdrawn while the switch is closed. These are not interchangeable roles: one is a general power receptacle, the other is a hazardous-location device.
5) What do I order if I need the matching plug supplied with the receptacle instead of a receptacle on its own?
The Cooper Wiring Devices single three-phase power receptacle is supplied as a receptacle only, in a single-outlet configuration for direct plug-in power connections. If the job needs the mating plug delivered with the outlet as one matched pair, the Appleton U-Line ECS factory-sealed 15 and 20 amp plug and receptacle set is a 3-pole set that includes both halves. Choose the set when nothing on the equipment cord is terminated yet and both ends have to be established together; choose the Cooper receptacle when the plug already exists on the equipment and only the outlet is being installed or replaced.
6) How do you terminate the wires on this Cooper three-phase receptacle?
Screw terminals. You strip and land the conductor under the terminal screw, so no push-in or back-wire shortcut and no crimp lugs. Plan the box fill and conductor length for a screw termination, and torque the screws to keep the connection tight under a three-phase load.
7) Are the contacts on the Cooper power receptacle brass or plated steel?
Solid brass contacts. Brass holds conductivity through repeated plug insertion and withdrawal, which matters on a receptacle that gets cycled by equipment cords rather than left plugged in. That is the spec to check if you are standardizing a facility and want the same contact material across every power drop.
8) What colors is the Cooper single power receptacle available in, and can I match the ones already in my building?
Seven colors across the range: brown, ivory, white, light almond, gray, red, and black. Brown, white, and light almond each show up at more than one voltage, so you can usually hold a device color standard across differently rated circuits. Red is offered at 125 volts (MPN 8310RD), which is the usual convention for marking an emergency or generator-backed circuit.
9) Is this a single receptacle or a duplex?
Single. One outlet per device, which is what you want when a single piece of equipment gets a dedicated circuit and you do not want a second cord landing on the same breaker. A duplex would let someone plug a second load onto a circuit sized for one machine.
10) I need a matching plug to go with a three-phase receptacle. Is one included?
The Cooper device is the receptacle only, so the mating plug or connector body is a separate line item. If you would rather buy the pair together and know they mate, the Appleton U-Line ECS factory-sealed 15 and 20 amp plug and receptacle set is a 3-pole plug and receptacle supplied as a set.
