Leviton LEV-2711 – Frequently Asked Questions

1) Will a Leviton L14-30P plug work on my generator cord for a 30A 125/250V transfer switch?
Yes, if the receptacle or inlet is NEMA L14-30. The Leviton 2711 is a NEMA L14-30P twist-lock plug rated 30A at 125/250V, 3-pole 4-wire, which is the standard generator cordset configuration carrying two hots, a neutral, and a ground. It only mates with an L14-30 receptacle or connector; it will not enter an L5-30, L6-30, or 14-30 straight-blade device.
2) Is the Pass & Seymour Turnlok L8 plug an equivalent to the Leviton 2731 480V locking plug?
They are both 480V 30A locking plugs but not the same configuration. The Leviton 2731 is an L16-30P at 480V, a 3-pole 4-wire device. The Pass & Seymour Turnlok L720P is a NEMA L8 three-wire plug rated 30A 480V with a black and white body. Three-wire L8 and four-wire L16 blade patterns do not interchange, so match the plug to the existing receptacle rather than to the voltage alone.
3) Is the Leviton L14-30P a true 3-phase plug?
The L14-30P is a 3-pole, 4-wire device rated 30A 125/250V. In practice on a generator or transfer switch cordset that means two hot legs, a neutral, and a ground, giving both 120V and 240V from the same connection. Leviton's own description lists it under 3-phase service; if your load is genuinely 3-phase 480V, use the L16-30P version (Leviton 2731) instead.
4) Is this Leviton locking plug rated for daily job-site handling or is it a residential-grade part?
It is built to Leviton's industrial grade standard, meant for repeated plugging and unplugging in commercial and industrial work rather than occasional household use. The twist-lock, polarized blade design keeps the cord from pulling free while equipment is running, which is why it shows up on temporary power, motor and machinery feeds, and portable cordsets.
5) What else could I use instead of the Leviton L14-30P for a smaller or heavier-duty locking connection?
It depends which way you are moving. For a lighter 15A 125V circuit, the Bryant 4722N is an angle locking plug in L5-15P. For a 30A 250V two-pole three-wire load with no neutral, the Eaton L6-30 nylon locking plug covers it. At the heavy end, the Eaton 7765 armored back-wiring plug is rated 50A 600V and built extra heavy duty. None of these mate with an L14-30 receptacle, so only switch if the receptacle changes too.
6) Can I put this Leviton locking plug on the end of an existing extension cord or cable assembly?
Yes. The 2711 is a cord-end plug intended to be wired onto cord and cable-connector assemblies, so it replaces a damaged plug on a generator cord or shop feeder. You need four conductors to land it correctly: two hots, neutral, and ground for the 3-pole 4-wire L14-30 pattern, and the cord must be sized for the 30A rating.
7) I need a locking plug for a 20A 120/208V circuit, not 30A. What is the alternative to the Leviton 2711?
The Leviton 2711 is rated 30A at 125/250V. For a 20A 120/208V connection, the Eaton 7411-C Safety Grip locking plug is rated 20A at 120/208V and is built to a heavy-duty specification grade. Confirm the NEMA configuration of the receptacle before ordering, since amperage and voltage alone do not determine the blade pattern.
8) What is a heavier-duty locking plug than the Leviton 2711 for a 50A feeder?
The Leviton 2711 is an industrial grade plug rated 30A. For a 50A connection, the Eaton 7765 industrial armored locking plug is rated 50A at 600V and 250Vdc, uses back-wiring terminations, and is built to an extra heavy duty grade. It is a different amperage class and a different body style than the 30A Leviton, so the mating receptacle must suit it.
9) Which locking plug do I use for a wet or dusty location instead of the Leviton 2711?
The Leviton 2711 is an industrial grade twist-lock plug in a black body with no enclosure rating stated. Where the connection sits in dust or washdown, the Pass & Seymour 267 Series rubber dust-tight locking plug in yellow is built for that duty. Match the NEMA configuration to the receptacle, as the 2711 is specifically L14-30P.
10) What color is the Leviton 2711 L14-30P plug body?
Black. If you are color-coding cordsets on a site, Pass & Seymour's 267 Series rubber dust-tight locking plug is offered in yellow, and the Pass & Seymour Turnlok L8 plug uses a black and white body.
