Pass & Seymour L720-P – Frequently Asked Questions

1) What does a NEMA L8 locking plug fit, and will it mate with an L6-30 receptacle?
The Pass & Seymour Turnlok L720P is a NEMA L8 configuration, 3-wire, 480V locking plug. NEMA configurations are not interchangeable, so it only mates with an L8 receptacle or connector of the same amp rating. It will not go into an L6-30 device, which is a 250V configuration. If your receptacle is L6-30, you want an L6-30 plug such as the Eaton L530P instead.
2) Which amp rating do I order, the 20A or the 30A Turnlok L8 plug?
Two Motor FLA ratings are offered: 20A, ordered as L720-P, and 30A, ordered as L830-P. Match the plug to the receptacle and the branch circuit, not to the motor alone. A 20A L8 receptacle will not accept the 30A plug.
3) Is this 480V plug rated for three-phase power?
The L720P Turnlok is a 3-wire, 480V device, which on an L8 configuration means two hot poles plus ground, so it is for 480V single-phase (or two legs of a three-phase system). For a true 480V three-phase load you need a 4-wire device such as the Leviton NEMA L16-30P, 30A 480V 3-phase plug.
4) Is the L720P heavy-duty enough for a 50A machine feed?
The L720P Turnlok covers 20A and 30A Motor FLA ratings at 480V, so it does not reach a 50A feed. For that load the Eaton 7765 is an industrial armored locking plug rated 50A 600V/250Vdc with back-wiring and is catalogued as extra heavy duty. Size the plug to the overcurrent protection on the circuit rather than to the cord alone.
5) What is the closest alternative to the Pass & Seymour L720P for a 480V circuit?
The L720P Turnlok is a NEMA L8 configuration, 3-wire plug rated 480V. If the equipment calls for 480V 3-phase instead, the Leviton 2341 is an industrial grade polarized locking plug rated 480V 3-phase, 30A, in NEMA L16-30P configuration. The two are not interchangeable at the receptacle - L8 and L16-30 are different blade patterns - so match the configuration stamped on the mating receptacle before ordering.
6) I need a locking plug for 250V, not 480V - what should I use instead of the L720P?
The L720P Turnlok is built for 480V 3-wire service, so it is the wrong device for a 250V circuit. For 250V two-pole work, the Leviton 4570-C is an industrial grade 2-pole locking plug rated 250V 15A in NEMA L6-15P, and the Leviton 2321 is an industrial grade locking plug rated 20A 250V in NEMA L6-20P. Choose by the amperage of the branch circuit and the receptacle configuration already in place.
7) My cord cap needs to land on a 4-wire receptacle - is the L720P the right plug?
No. The L720P Turnlok is a 3-wire device, which gives two hot poles plus ground and no neutral. For a 4-wire opening, the Leviton 2411 is an industrial grade 4-wire locking plug rated 125/250V 3-phase 20A. A 3-wire plug will not seat in a 4-wire receptacle, so confirm the wire count on the cord and the receptacle together.
8) Can I use this locking plug on a cord outdoors or in a wet, oily area?
The Turnlok L8 plug is built for that kind of service. The nylon 6 shell resists impact and corrosion, and an integral flexible rubber grommet seals around SO cord to keep oils, water and chips out of the wiring chamber. A double dovetail design resists cord pull-out. It is a cord-end plug, so the receptacle or connector it mates into still has to suit the location.
9) Is the Pass & Seymour L720P UL listed for code-compliant installations?
Yes, the L720P Turnlok L8 plug is cULus Listed across both the 20A and 30A options, which covers both US and Canadian requirements for inspected work.
10) How does this plug wire up, and does it need any extra parts?
Wiring is from the cord end: the assembly screws and cord-grip screws arrive backed out ready to wire, and the external cord grip gives you a visible check that the cord is properly retained. Brass alloy blades handle the current. You supply the cord (SO cord suits the grommet) and the mating L8 receptacle or connector; nothing else ships with the plug.
11) Will a twist-lock plug stay connected on vibrating machinery better than a straight-blade plug?
That is the reason to choose it. The Turnlok connection twists to lock, so the plug cannot vibrate out of the receptacle the way a straight-blade cap can. Raised ribs and a scallop shell profile give a non-slip grip for turning it in and out, which matters with gloves on. For equipment on temporary or frequently moved power drops, the locking type is the right call.
12) What are the other locking plug options if my circuit is 250V or 120V rather than 480V?
The Turnlok L720P family is 480V only, so step down to the matching configuration. For 250V, 20A there is the Leviton NEMA L6-20P industrial grade plug, or the Leviton L6-15P at 15A. For 125V, 15A, the Bryant 4722N is an angle L5-15P. Eaton also offers an industrial 20A 120/208V safety grip plug. Pick by the receptacle configuration already on the wall.
13) What is the difference between the Pass & Seymour L720P and the Eaton L530P locking plug?
The Pass & Seymour L720P is a Turnlok 3-wire NEMA L8 plug rated 480V, offered in 20A and 30A Motor FLA options with a nylon 6 shell. The Eaton L530P is a two-pole three-wire nylon locking plug in the L6-30 series and is catalogued as commercial grade. Both are twist-lock nylon-bodied plugs, but the blade configurations differ, so they mate to different receptacles.
14) Is there a simpler locking plug for 120V tool cords instead of the L720P?
Yes. The L720P Turnlok is a 480V device and is not suitable for 120V cord work. The Bryant 4722N is an angle locking plug in NEMA L5-15P rated 15A 125V, which is the common choice for 125V tool and extension cords. The Eaton 7411-C Safety Grip locking plug is rated 20A 120/208V and is catalogued as heavy-duty specification grade if the cord carries a 20A load.
15) What color is the Pass & Seymour Turnlok L8 plug, and is the rating marked on it?
It is a two-tone body, black back with a white front, catalogued in black. The NEMA L8 configuration and device rating are stamped visibly on the plug, so an electrician or maintenance tech can confirm the right device on an energized floor without pulling paperwork.
16) Does a non-metallic locking plug like the Bryant 71020NP do the same job as the L720P?
Both are non-metallic bodied twist-lock plugs - the L720P Turnlok uses a nylon 6 shell and the Bryant 71020NP is a 7 Series non-metallic locking plug. Where they part company is the electrical identity: the L720P is a 3-wire NEMA L8 device rated 480V in 20A and 30A Motor FLA options. Match the NEMA configuration on your receptacle, not the housing material, when deciding between them.
17) Where is the Pass & Seymour L720P made?
The Turnlok L8 locking plug is manufactured in Mexico. That matters on jobs with country-of-origin documentation requirements, such as government or institutional procurement.
