Leviton 279-S00 – Frequently Asked Questions

1) What is the difference between the Leviton 278-S00, 279-S00 and 5372-S00 receptacles?
Three different circuits. The 279-S00 is the 50A 14-50R, four-wire at 125/250V. The 278-S00 is the 30A version of the same four-wire pattern, 14-30R at 125/250V, the dryer outlet. The 5372-S00 is 30A 6-30R at 250V only, which is three-wire: two hots and a ground, no neutral. Pick by what your circuit actually has. If the equipment needs 120V for controls or a clock, you need the neutral, so 14-30R or 14-50R.
2) Can I use a 50A NEMA 14-50 receptacle to replace an old three-prong 10-50 range outlet?
Not as a direct swap. The 14-50R is a four-wire device and needs a separate neutral and an equipment ground pulled to the box. An older 10-50 outlet was fed with three conductors, no separate ground. Feeding a 14-50R off that cable leaves the ground terminal dead. If the existing circuit only has three conductors, either pull new cable or stay with the wiring configuration that circuit was built for.
3) Is a Leviton industrial grade receptacle worth it over a residential one for a shop or plant?
Industrial grade is the point of the 279-S00. It is the tier above residential and spec grade, built for repeated plug-in cycles, vibration and rough handling in panel rooms, plants and job-site power. For a receptacle a tenant plugs a range into twice a decade, the grade matters less. For a machine cord that gets pulled daily, or maintenance carts, that contact retention is what stops the loose, heat-cycling connection that eventually cooks a device.
4) Is the Leviton 14-50R a single or duplex receptacle, and what circuit does it need?
Single position, one device per opening. That is normal for 50A: the outlet gets its own dedicated 50A two-pole circuit and nothing else shares it. Wiring is two hots, neutral and ground at 125/250V. A duplex 50A device is not a thing you would spec here, so plan the rough-in for one receptacle on one homerun.
5) I need a 30A dryer outlet, not a 50A range outlet. Does Leviton make the same device in 30A?
Yes, in two shapes. The 278-S00 is 30A 14-30R at 125/250V, the four-wire dryer pattern. If your load is 240V only with no neutral, such as a heater or a welder circuit, the 5372-S00 is 30A 6-30R at 250V. Both are the same industrial grade line as the 50A 14-50R version, so specify by the plug on the equipment rather than by the amperage alone.
6) What color is the Leviton 50A 14-50R industrial receptacle, and does it matter for a facility standard?
Black. Across a facility, color is often how crews tell voltage or circuit type apart at a glance, so if your standard uses color coding on wiring devices, black is what these arrive as. There is no other body color on the 14-50R, 14-30R or 6-30R versions.
