Leviton LEV-2311 – Frequently Asked Questions

1) Will a Leviton 4570-C plug fit a NEMA L6-15 receptacle at 250V?
Yes. The 4570-C is built to the NEMA L6-15P configuration, so it twists into any L6-15R receptacle on a 250V single-phase circuit. It is a 3-wire, 2-pole polarized device (two hots plus ground), rated 250V, 15A. It will not mate with an L5-15 receptacle, which is a 125V configuration on a different blade pattern.
2) I need a 15A locking plug for a 125V circuit, not 250V. What should I use instead of the Leviton 4570-C?
The Leviton 4570-C is a 250V, 15A NEMA L6-15P device and is the wrong configuration for a 125V circuit. For 125V at 15A, the Bryant 4722N is an angle locking plug in the NEMA L5-15P configuration. L5-15 and L6-15 blades are not interchangeable, so confirm the receptacle configuration before ordering.
3) What is the difference between the Leviton 4570-C locking plug and the Eaton L6-30 locking plug?
Both are two-pole, three-wire locking plugs for 250V circuits, but they are different NEMA configurations and will not mate with the same receptacle. The Leviton 4570-C is a NEMA L6-15P rated 250V, 15A and built to Industrial Grade. The Eaton L530P is an L6-30 series plug with a nylon body and a Commercial grade rating. Match the plug to the receptacle configuration and the branch circuit ampacity already in place - an L6-15P will not enter an L6-30 receptacle.
4) What is the difference between a locking plug like the L6-15P and a straight-blade plug for industrial equipment?
A locking plug uses a curved blade pattern that you push in and twist, so the connection holds against vibration and cord pull. A straight-blade plug pulls straight out. For machine tools, portable equipment, and temporary job-site power, the twist-lock is what keeps equipment from dropping offline when a cord gets tugged. The 4570-C's L6-15P pattern does that on a 250V single-phase circuit.
5) Is the Leviton 4570-C rated for industrial use or is it just a commercial-grade plug?
It's an Industrial Grade device. That's the construction standard Leviton builds it to for repeated plugging and unplugging in shops, plants, and temporary power setups, not a residential or general-purpose grade.
6) Does the Leviton 4570-C carry a ground, or is it just two hot conductors?
Three wires: two poles plus an equipment ground. The polarized blade orientation forces the conductors into the right terminals, which is what keeps the ground path correct on a cord set you're building in the field.
7) What other Leviton model numbers come under this locking plug offering?
Four Leviton models are covered: 4570-C, 2311, 6365-CR and 26W47. The 4570-C is the Industrial Grade L6-15P, 250V 15A device. Order by the model number itself so you get the configuration your receptacle takes.
8) Can I use a 15A L6-15P plug on a 50A or 600V circuit?
No. The 4570-C tops out at 250V, 15A. For heavy feeders you need a device built for it, such as the Eaton armored locking plug rated 50A, 600V/250Vdc with back-wiring, which is an Extra Heavy Duty grade device. Never fit a 15A plug to a circuit whose overcurrent protection exceeds the plug's rating.
9) Is there a locking plug with a tougher body than the Leviton 4570-C for rough service?
The Leviton 4570-C is built to Industrial Grade for repeated use in commercial and industrial settings. If the cord end takes impact or crushing abuse, the Eaton 7765 is an armored industrial locking plug rated Extra Heavy Duty at 50A, 600V/250Vdc with back-wiring, and the Eaton 7411-C Safety Grip plug is a Heavy-Duty Specification Grade device at 20A, 120/208V. Both are different electrical ratings and configurations from the L6-15P, so they are alternatives only where the circuit rating matches.
10) Can I substitute a Bryant 71020NP for the Leviton 4570-C?
Not as a straight swap. The Bryant 71020NP is a 7 Series non-metallic locking plug, a different series from the Leviton 4570-C, which is a NEMA L6-15P Industrial Grade plug rated 250V, 15A, 3-wire 2-pole. Locking devices only mate when the NEMA configuration is identical, so verify the 71020NP configuration against the receptacle rather than substituting on grade alone.
11) For a job site temporary power cord set, does the Leviton 4570-C or the Eaton 7411-C make more sense?
It depends on the circuit. The Leviton 4570-C is a 250V, 15A single-phase L6-15P plug built to Industrial Grade and is used on industrial power distribution and cord sets, job site temporary power, and portable equipment cords. The Eaton 7411-C is a Safety Grip locking plug rated 20A at 120/208V and carries a Heavy-Duty Specification Grade rating. Choose by the voltage and amperage of the receptacle feeding the cord set, since the two are not the same configuration.
12) How do I tell this Leviton locking plug apart from others on a cart of cord sets?
The housing is a Black/White color combination, which is the quick visual cue on a job site where several NEMA configurations are in play. Colour alone isn't a rating though, so read the L6-15P stamp before you plug into anything.
