Eaton 7379 – Frequently Asked Questions

1) What wire size can I land on the Eaton 50A industrial locking receptacle?
It takes #10 through #6 AWG, terminated back-wired rather than under side screws. At a 50A load you are typically pulling #6 copper, which is the top of that range, so check your conductor insulation and lug space before you cut. The back wiring method helps when you are working in a tight enclosure and cannot get a screwdriver to the side of the device.
2) Is the Eaton 7379 receptacle rated for 600 volt three-phase equipment?
Yes, it is rated 600 Vac and 250 Vdc at 50A, and it is a three-pole device with a grounding conductor. That covers 480V and 600V three-phase machine hookups as well as DC circuits up to 250V. Note the three poles plus ground: this is not a four-wire device, so it does not carry a separate neutral.
3) Can this 50A locking receptacle be mounted outdoors or in an unheated building?
Its operating range is -40 to 105 C (-40 to 221 F), so cold storage, unheated warehouses, and hot process areas are all within spec. The face and body are glass filled nylon over a steel body with zinc plated brass contacts, which holds up to vibration and corrosion. It is not, however, an explosionproof device. For a classified hazardous area you need something like the Appleton FSQC Series interlocked explosionproof receptacle instead.
4) I only need 30 amps for this machine hookup, is there a smaller single locking receptacle than the Eaton 7379?
Yes. The Eaton 7379 is rated 50A and is sized for extra heavy duty industrial power circuits. For a 30A locking drop, the Pass & Seymour L2130R is a 30A L2130 single receptacle in black, the same single-receptacle style of device at a lower current rating. Confirm the machine cord plug matches the L2130 configuration, since the 7379 uses a non-NEMA locking interface that will not accept an L2130 plug.
5) Can I use the Eaton 7379 in a hazardous or classified area?
The Eaton 7379 is a UL Listed industrial locking receptacle with a steel body and glass filled nylon face, built for extra heavy duty industrial duty, but it is a general industrial device and not an explosionproof one. For a classified location, the Appleton FSQC Series interlocked explosionproof receptacle is the device built for that purpose, and the Appleton U-Line ECS factory-sealed 15 and 20 amp plug and receptacle set is a 3-pole factory-sealed option at lower amperage. Match the device to the area classification on the drawing before ordering either.
6) How much space do I need in the enclosure for the Eaton 50A locking receptacle?
The device measures 2.38 in wide by 2.38 in high with a 3.75 in depth behind the face. The depth is the number that usually decides it: allow 3.75 in of clear space inside the box or enclosure plus room for the #6 conductors to bend behind the back-wired terminals.
7) What is the difference between an extra heavy duty industrial receptacle and a spec grade one?
Device grade is about duty cycle and abuse tolerance. The Eaton 7379 is built to extra heavy duty grade for continuous industrial service at 50A and 600V, with a locking connection meant to survive vibration on machinery. Spec grade and heavy duty commercial wiring devices, like the Pass & Seymour 26352W specification grade decorator duplex or the Bryant 5362B heavy-duty duplex, are 20A/125V general-purpose convenience outlets for walls and workbenches. They are not substitutes for each other; they serve different circuits entirely.
8) Is the Eaton 7379 a duplex or single outlet?
Single. It is a single receptacle design, one locking outlet per device, which is what you want on a dedicated 50A machine circuit. If you need two outlets on one strap for general 20A/125V use, that is a duplex device such as the Bryant 5362BI or the Pass & Seymour 3232TRW Trademaster tamper-resistant duplex, not this one.
9) Will this locking receptacle stay connected on a vibrating machine?
That is the point of the safety grip locking flanged outlet on the Eaton 7379. The plug twists into the receptacle and is mechanically retained rather than held by friction, so vibration and cable tug will not walk it loose the way they will with a straight-blade outlet. Combined with the extra heavy duty grade and the steel body, it is built for machine and portable power hookups where an accidental disconnect drops production.
10) Is a heavy-duty 20A duplex receptacle an acceptable substitute for the Eaton 7379?
No. The Eaton 7379 is a three-pole single locking receptacle rated 50A at 600 Vac, back wired for #10-6 AWG conductors. Devices such as the Bryant 5362B heavy-duty 20A/125V duplex, the Bryant 5362BI heavy-duty duplex, or the Pass & Seymour 26352W 20A 125V specification grade decorator duplex are 20A 125V straight-blade duplex outlets for general convenience power. They neither lock nor carry the current the 7379 is built for, so they are not interchangeable on a 50A machine circuit.
11) What should I use instead of the Eaton 7379 for a 277V motor disconnect?
The Eaton 7379 is a three-pole device rated 600 Vac and 250 Vdc for industrial power circuits. If the application is a two-pole 277V motor connection, the Bryant 430R9W 4750DR is a 2-pole 3-wire 277V motor-duty receptacle built for that service. The 7379 remains the choice where a three-pole 50A locking connection is specified.
12) For a healthcare or occupied-space outlet, is the Eaton 7379 the right device?
The Eaton 7379 is an industrial application device in black, intended for plant floor power distribution and machinery hookups. For patient-care and occupied spaces the relevant devices are ones like the Pass & Seymour 2097HGI hospital grade 20A duplex self-test GFCI in ivory, or the Pass & Seymour 3232TRW Trademaster tamper-resistant duplex in white where tamper resistance is required. Those address the code requirements for those rooms; the 7379 addresses a locking 50A industrial connection.
