Pass & Seymour L1120-R – Frequently Asked Questions

1) What wire size can I land on this 20A locking receptacle?
It takes #14 through #10 AWG, and you have two ways in: side screws or external screw-pressure-plate back wiring. For a 20A 3-phase branch circuit run in #12, that is right in the middle of the range. #8 and larger will not land on it.
2) Can I use an L1120 locking receptacle on a 208V or 240V three-phase motor circuit?
The device is rated 250V, 3-phase, 20A, so it covers the usual 208V and 240V three-phase delta services as long as the load draws 20 amps or less. Because the L1120 is a 3-wire configuration with no ground pin, it suits equipment where the grounding path is handled outside the connector. If the equipment needs a grounded locking connection, specify the grounding version of the configuration instead.
3) What is the closest alternative to the Pass & Seymour L1120-R if the equipment needs a locking receptacle above 20 amps?
The Pass & Seymour Turnlok L1120-R is a NEMA L1120 locking receptacle rated 20A, 250V with a black nylon face and body. When the load exceeds that, the Eaton 7379 industrial locking receptacle is rated 50A at 600V/250V AC/DC and is also black, built to an extra heavy duty grade. Both are locking devices, so the cord cap must match the receptacle's NEMA configuration exactly - a plug made up for L1120 will not engage the Eaton 50A device.
4) Can a Leviton 16352-1PW or Decora Plus 16342 be used in place of a Pass & Seymour L1120-R?
No. The Leviton 16352-1PW and the Decora Plus 16342 are both 20A 125V NEMA 5-20R straight blade duplex receptacles, commercial grade. The Pass & Seymour Turnlok L1120-R is a NEMA L1120 locking configuration rated 20A, 3-phase, 250V. The amperage matches, but the voltage, the blade pattern and the twist-to-lock retention do not, so a cord cap built for L1120 has no mating path into either Leviton device.
5) We need a locking-style power connection in a hazardous classified area - is the Pass & Seymour L1120-R suitable, or is there a different device?
The Pass & Seymour Turnlok L1120-R is a UL Listed general industrial and commercial locking receptacle in a nylon face and body; it is not an explosionproof device. For a classified area, the Appleton FSQC series interlocked explosionproof receptacle is the device built for that duty, and the Appleton U-Line ECS factory-sealed 15 and 20 amp plug and receptacle set is a 3-pole factory-sealed alternative in the same family of applications.
6) Is this receptacle UL Listed for industrial equipment hookups?
Yes, the Turnlok L1120-R is UL Listed, and the NEMA configuration, electrical rating, and the third-party listing mark are all printed on the face of the device so an inspector or electrician can verify it after install without pulling the plate.
7) Why pick a locking receptacle over a standard straight-blade 20A outlet?
A twist-lock holds the plug mechanically, so vibration from a motor or someone dragging a cord will not drop the connection. Straight blade is the wrong tool for that. If what you actually need is 20A 125V single-phase for general commercial use, a straight-blade 5-20R device such as the Leviton Decora Plus 16342 or the Bryant 5362B heavy-duty duplex is the simpler choice. The L1120 is for three-phase 250V machinery and portable power where the cord must stay put.
8) I need a higher amperage locking receptacle than 20A, what else is there?
The L1120-R tops out at 20A. For heavier loads, the Eaton industrial locking receptacle 7379 is rated 50A at 600V/250V AC/DC and is built to an extra heavy duty grade. For hazardous locations the locking format will not help you at all, you want a factory-sealed or explosionproof device such as the Appleton FSQC Series interlocked explosionproof receptacle.
9) How does the Pass & Seymour L1120 receptacle ship, and do I get a matching plug with it?
The receptacle is sold as a device only, packaged 10 each, under part number L1120-R. No mating plug is included, so order the L1120 plug separately. If you want the plug and receptacle together as a matched set, the Appleton U-Line ECS factory-sealed 15 and 20 amp plug and receptacle set is a 3-pole assembly sold as a pair.
10) What should I use for a 277V motor connection instead of the Pass & Seymour L1120-R?
The Pass & Seymour Turnlok L1120-R is rated 250V, 20A in the NEMA L1120 configuration. For a 277V motor circuit, the Bryant 430R9W of the 4750DR series is a 2-pole 3-wire 277V motor-duty receptacle. The two differ in voltage rating and in the mating configuration, so the cord end has to be selected to match whichever receptacle goes in.
11) If the receptacle only feeds 120V single-phase tools, is the Pass & Seymour L1120-R overkill?
Yes, for a straight 120V tool outlet the Turnlok L1120-R is the wrong configuration - it is a 3-wire L1120 locking device rated 20A, 3-phase, 250V. For 20A 125V general-duty outlets, the Bryant 5362B heavy-duty duplex receptacle is a 20A/125V device, and the Bryant 21254IGO is a NEMA 5-20R quad straight-blade receptacle at 20A where four outlets are wanted in one box.
12) Does the Pass & Seymour L1120-R accept the same conductor sizes as an Eaton industrial specification grade receptacle?
Yes on wire range. The Pass & Seymour Turnlok L1120-R accepts #14 to #10 AWG with side wiring and external screw pressure-plate back wiring, and the Eaton 6450W heavy-duty industrial specification grade decorator single receptacle is also specified for #14-10 AWG. The devices differ in configuration - the Pass & Seymour is a 250V L1120 locking receptacle, the Eaton is a decorator-style single receptacle.
13) For a patient care area, can the Pass & Seymour L1120-R be used, or is a hospital grade device required?
The Pass & Seymour Turnlok L1120-R is a UL Listed industrial locking receptacle rated 20A, 250V, 3-phase, and is not a hospital grade device. Where the facility requires hospital grade marking, the Leviton 16262-HGW is a hospital grade duplex receptacle in white. Confirm the configuration the equipment cord carries before substituting, since the Leviton is a duplex straight-blade device rather than a locking one.
14) How durable is the body and strap on this Turnlok receptacle for a shop floor?
The face and body are nylon, ultrasonically welded together rather than screwed, and the mounting strap is a single piece of solid brass with no rivets to work loose over time. Contacts are one-piece high-grade brass for conductivity and heat-rise resistance. That construction is aimed at repeated plug cycles in industrial and commercial spaces.
15) What color is the L1120-R and does the color mean anything?
Black face and body. Pass & Seymour color codes Turnlok faces by voltage class, which helps crews match a plug to the right receptacle in a room full of locking devices rather than reading every face. The rating is still stamped on the face for confirmation.
16) What is the difference between the Pass & Seymour L1120-R and a commercial specification grade single receptacle like the Eaton 816W?
The Eaton 816W is a commercial specification grade single receptacle rated 15A, with a straight-blade face. The Pass & Seymour Turnlok L1120-R is a 20A, 250V, 3-phase L1120 locking single receptacle with a one-piece solid brass mounting strap and one-piece brass contacts, with the NEMA configuration, rating and third-party listing marked on the face. Amperage, voltage and the plug retention method all differ, so they are not interchangeable at the same opening.
17) Is there an impact-resistant alternative to the Pass & Seymour L1120-R for general commercial outlets?
The Pass & Seymour Turnlok L1120-R uses a compact nylon face and body ultrasonically welded together for impact resistance, in a NEMA L1120 locking configuration. For straight-blade commercial outlets with similar toughness, the Leviton 16251W is a commercial grade heavy-duty impact-resistant straight blade receptacle, and the Eaton 5262W is an Arrow Hart heavy-duty industrial duplex rated 15A 125V, 5-15R, in gray. Those are non-locking devices, so they suit cord caps without twist-lock blades.
18) We stock Bryant 5362BI receptacles for our shops - does the Pass & Seymour L1120-R replace them?
No. The Bryant 5362BI is a 20A/125V heavy-duty duplex receptacle, a two-outlet straight-blade device for 125V branch circuits. The Pass & Seymour Turnlok L1120-R is a single-outlet L1120 locking receptacle rated 20A, 3-phase, 250V and is intended for 3-phase equipment connections, motors and machinery. They serve separate circuits and should be stocked alongside each other rather than one for the other.
