Leviton 688-W – Frequently Asked Questions

1) Which Leviton single receptacle do I order for a 250V 20A piece of equipment?
For a 250V, 20-amp load the Leviton commercial grade single receptacle to order is the NEMA 6-20R version, model 16451-W in white. The 6-20R face accepts a 20A 250V straight blade plug, and it will also take a 6-15R plug because the 6-20R slot pattern is T-shaped. If the equipment cord is a 6-15P only and the circuit is 15A, the brown 5661 in NEMA 6-15R is the match instead.
2) What is the difference between the Leviton 5661 and the 688-W single receptacles?
Voltage and blade pattern. The 5661 is a 250V, 15A NEMA 6-15R in brown, with two horizontal blade slots for 240V equipment. The 688-W is a 125V, 15A NEMA 5-15R in white, the standard household/office pattern. They are not interchangeable, and the plug on your equipment decides which one you need.
3) Can I put the 250V Leviton 6-15R receptacle on a 20-amp circuit?
No. The 5661 is rated 15A at 250V in a NEMA 6-15R configuration, and a single receptacle has to match the branch circuit rating, so a 20A circuit serving one single receptacle takes a 20A device. For that case use the 16451-W, which is the 20A 250V NEMA 6-20R version.
4) Why use a single receptacle instead of a standard duplex outlet?
A single receptacle gives one outlet per device opening, which is what the code path calls for when a dedicated branch circuit serves one piece of equipment, and it physically prevents anyone from plugging a second load onto that circuit. The Leviton commercial grade straight blade single is the device to use behind a copier, a compressor, a window AC unit, or any appliance that needs its own circuit. If you want two outlets on a general-purpose circuit, use a duplex instead.
5) Is this receptacle tough enough for a shop or a warehouse wall?
It is built as a commercial grade device with an impact-resistant smooth face, which is the construction level specified for shops, plants, schools, and other facilities where devices get knocked by carts and cords. That is a step above residential grade. For areas that are wet or subject to hose-down, you still need an appropriate weatherproof enclosure and cover over it.
6) Do I need a special wall plate for a single receptacle like the Leviton 688-W?
Yes, a single-receptacle wall plate, not a duplex plate. These devices use a round single opening rather than the figure-eight duplex cutout, so a standard duplex plate will not cover the face correctly. Plates are ordered separately from the receptacle.
7) What colors does the Leviton commercial grade single receptacle come in?
Two: white and brown. The white options are the 688-W (125V 15A, NEMA 5-15R) and the 16451-W (250V 20A, NEMA 6-20R); the brown option is the 5661 (250V 15A, NEMA 6-15R). If you are matching existing brown devices in an older building, the 5661 is the brown one on offer.
