Cooper Wiring Devices 5759 – Frequently Asked Questions

1) What does a NEMA 14-20R receptacle plug into, and will a regular 5-20 plug fit it?
The Cooper 5759 is a NEMA 14-20R configuration, which is three-pole, four-wire grounding: two hots, a neutral, and a ground. A standard 5-20 cord cap will not fit it, and neither will a 14-30 or 14-50 plug. Only a 14-20P cord cap mates with it. That four-wire setup is what lets equipment draw both 125V and 250V from the same outlet, which is why the rating reads 125/250V at 20A.
2) What wire size can I land on the Cooper 5759 receptacle terminals?
Terminals take #12 through #4 AWG, so a 20A branch circuit run in #12 lands fine and there is headroom if the run is long enough to need upsized conductors. Terminations are screw type, back wired, so you strip and clamp under the screw rather than using a push-in hole. Four conductors go in: two hots, neutral, and equipment ground.
3) Do I need to run a neutral for this receptacle, or will three wires do?
A neutral is required. This is a four-wire device: two ungrounded conductors, a grounded (neutral) conductor, and an equipment ground. If your existing feed is only two hots plus a ground, you cannot land it on a 14-20R without pulling a neutral. Equipment that needs no neutral would use a three-wire configuration instead.
4) What should I use instead of the Cooper 5759 if the equipment cord is a standard 20A 125V straight-blade plug?
The Cooper 5759 is a three-pole, four-wire grounding device in the NEMA 14-20R configuration rated 125/250V, so it will not accept a standard two-pole 125V cord cap. For a 20A 125V opening, the Leviton CR20-GY is a commercial specification grade 20 amp duplex receptacle in the NEMA 5-20R configuration with self-grounding, and the Bryant 5362B is a heavy-duty 20A/125V duplex. Either takes an ordinary 5-20P equipment cord the 14-20R will not.
5) Is there a locking version if the cord needs to stay put on vibrating equipment?
The Cooper 5759 is a flush-mount straight-blade 14-20R, so a plug can be pulled straight out. Where a twist-lock connection is wanted, the Pass and Seymour L2130R is a 30A L2130 single receptacle in black, and the Bryant 70520FR is a flanged locking receptacle in the 7 Series. The Eaton 7379 is an industrial locking receptacle rated 50A, 600V/250V AC/DC in black. All three use a locking blade pattern, so cords and any devices already built for 14-20R straight blades will not mate with them.
6) We need a three-pole receptacle for a hazardous location. Does the Cooper 5759 work there?
The Cooper 5759 is a general-purpose flush receptacle in glass-filled nylon for commercial and industrial power distribution. For classified areas, Appleton makes three-pole devices built for the duty: the U-Line ECS factory-sealed 15 and 20 amp plug and receptacle set is a 3-pole assembly, and the FSQC Series is an interlocked explosionproof receptacle. Those come as sealed or interlocked enclosures rather than a flush device in a standard box.
7) The motor circuit is 277V. Will the Cooper 5759 serve it?
No. The Cooper 5759 is rated 125/250V on a three-pole, four-wire grounding configuration. For a 277V motor connection, the Bryant 430R9W is a 4750DR series 2-pole 3-wire 277V motor-duty receptacle. That is a two-pole three-wire device, so it does not carry the separate neutral and ground the 14-20R four-wire arrangement provides.
8) Is this a flush mount or a surface mount receptacle?
Flush mount. The 5759 sets into a box so the face sits level with the wall or panel surface, which is what you want in a finished commercial space or on a panelboard face. If the job calls for a surface-mounted device on exposed conduit, this is not the right body style.
9) My equipment cord has a twist-lock plug. Can I use this receptacle?
No. The 5759 is a straight-blade flush receptacle, so a twist-lock cord cap will not engage it. For locking cords you need a matching locking device, for example the Bryant 70520FR flanged locking receptacle or the Pass and Seymour L2130R 30A single receptacle. Match the locking configuration stamped on your plug before you order.
10) Does the Cooper 5759 give me GFCI or AFCI protection on the circuit?
The Cooper 5759 is a straight power-style 14-20R device with back-wired screw terminals and no built-in protection electronics. If the circuit requires device-level protection, the Leviton G5362-WTE is a SmartlockPro GFCI duplex, 20A 125V, weather and tamper-resistant in black; the Pass and Seymour 2097HGI is a hospital grade 20A duplex self-test GFCI in ivory; and the Leviton AFTR2-HG is an AFCI duplex, hospital grade tamper-resistant, 20A 125V. All three are 125V duplex devices, so they serve a different load than a 125/250V four-wire connection.
11) For a healthcare facility, can the Cooper 5759 be used at patient care outlets?
The Cooper 5759 is an industrial-style 14-20R power receptacle and is not a hospital grade device. Where hospital grade is specified, the Leviton 16262-IGG is a Decora Plus hospital-grade isolated-ground duplex, 15A/125V in gray, and the Pass and Seymour 2097HGI is a hospital grade 20A duplex self-test GFCI. Both are 125V duplex receptacles for cord-connected patient equipment rather than a four-wire 125/250V connection.
12) What is a simpler receptacle for a general office or tenant space where the Cooper 5759 is overkill?
The Cooper 5759 accepts #12 to 4 AWG conductors and is built for heavy-duty equipment and power distribution circuits. For ordinary convenience outlets, the Pass and Seymour 3232TRW is a Trademaster tamper-resistant duplex in white, the Eaton 816W-BOX is a commercial specification grade single receptacle rated 15A, and the Pass and Seymour 26352W is a 20A 125V heavy-duty spec grade decorator duplex in white. These land conventional branch-circuit wire sizes rather than the large feeders the 5759 terminal accepts.
13) Will the glass-filled nylon body hold up in an industrial shop environment?
The 5759 body is molded glass-filled nylon, which is the standard material for heavy use devices because it resists heat and impact better than a thermoset or standard nylon face. Color is black. For genuinely hazardous or wash-down locations, though, an ordinary flush device is the wrong tool. An explosionproof option like the Appleton FSQC Series interlocked receptacle covers that instead.
14) What model number do I order for the Cooper 14-20R receptacle?
Order Cooper Wiring Devices part 5759. It is a single model with no finish or amperage options to pick, black, 20A, 125/250V, NEMA 14-20R.
15) If I want a black receptacle to match the Cooper 5759 elsewhere on the job, what else comes in black?
The Cooper 5759 has a black glass-filled nylon body. For matching black devices on the same job, the Leviton G5362-WTE SmartlockPro GFCI duplex, 20A 125V weather and tamper-resistant, is offered in black, the Pass and Seymour L2130R 30A single receptacle is black, and the Eaton 7379 industrial locking receptacle, 50A 600V/250V AC/DC, is black. Each of those is a different configuration, so match the color for appearance only and confirm the blade pattern against the equipment.
16) Is there a single-outlet spec grade device comparable to the Cooper 5759 for a dedicated appliance?
The Cooper 5759 is a single flush-mounted outlet dedicated to one 14-20R connection. On 125V circuits the closest single-outlet equivalents are the Eaton 6450W, a heavy-duty industrial specification grade decorator single receptacle taking #14-10 AWG, and the Eaton 816W-BOX commercial specification grade single receptacle rated 15A. Both land smaller conductors than the #12 to 4 AWG range the 5759 terminals accept.
