Leviton 2423 – Frequently Asked Questions

1) What is the difference between the L14-30R and L16-30R versions of this Leviton connector?
Both are 30 amp, but the L14-30R runs 125/250V 3-pole 4-wire, so it carries two hots, a neutral and a ground and can feed both 120V and 240V loads. The L16-30R is 480V, used for 3-phase equipment with no neutral. Feeding a 120V load off an L16 circuit is not possible, so the choice follows what the panel and the machine actually supply.
2) My circuit is 30A 250V two-pole three-wire, not four-wire. What locking connector should I use instead of the Leviton L14-30R?
The Leviton 2713 is a three-pole four-wire L14-30R device and will not land a two-pole three-wire circuit. For a 30A two-pole three-wire opening, the Eaton Arrow Hart Ultra Grip locking connector in the L6-30 series is a 30A two-pole three-wire nylon device. The L14 and L6 configurations are not interchangeable at the plug face, so the mating plug or cord cap on the equipment determines which one you order.
3) What is the closest equivalent to the Leviton 2713 locking connector if I need a 20A NEMA L14-20 instead of 30A?
The Leviton 2713 is a 30A 125/250V NEMA L14-30R connector. For the same 125/250V four-wire configuration at 20 amps, the Eaton Arrow Hart Ultra-Grip L14-20 connector is rated 20A 125/250V in the NEMA L14-20 configuration. Note the grade difference: the Leviton is an industrial grade device, while the Eaton Ultra-Grip L14-20 is a commercial grade device, so for high-vibration industrial or temporary power service the amperage step-down also comes with a different duty classification.
4) Is this Leviton locking connector rated for industrial use or is it a commercial device?
Industrial grade. It is built for heavy-duty power distribution, motor and machinery wiring, and high-vibration areas where a straight-blade device would shake loose. If you only need a commercial-duty 125/250V locking connector, the Eaton Arrow Hart Ultra-Grip L14-20 is a commercial grade option at 20A.
5) Why choose a locking connector instead of a standard straight-blade device for shop equipment?
A locking connector twists into place and holds, so vibration from motors, foot traffic on a cord run, or a tug on a temporary power drop will not pull the connection apart. That is the reason this Leviton device is specified for industrial and multi-circuit setups. A straight-blade device relies on blade friction alone and will back out.
6) Does the L15-20R version carry a neutral?
No. The L15-20R is a 20 amp 250V configuration, three-pole three-wire with no neutral, so it serves 3-phase 240V loads only. If you need 120V available at the same connector, use the L14-30R version instead.
7) Is a Bryant 7 Series non-metallic locking connector a drop-in substitute for the Leviton 2423?
They are both locking connectors, but they are not automatically interchangeable. The Leviton 2423 is a 20A 250V NEMA L15-20R device, and the NEMA configuration is what has to match the mating plug. The Bryant 71020NC is a 7 Series non-metallic NEMA locking connector, and the Bryant 70520NCC is a 705 Series device. Confirm the NEMA configuration on the Bryant part matches L15-20R before treating either as a substitute; the housing construction differs as well, since the Bryant 7 Series is non-metallic.
8) I need a 480V connector - does any of the Eaton or Bryant locking connectors cover that instead of the Leviton 2733?
The Leviton 2733 is the 30A 480V NEMA L16-30R connector, a three-pole four-wire device for 480V three-phase work. Among the comparable locking connectors, the Eaton Ultra Grip L6-30 is a 30A two-pole three-wire device and the Eaton L14-20 is a 20A 125/250V device, neither of which is an L16-30R replacement. For a 480V L16-30R opening, stay with the Leviton 2733 configuration.
9) For heavy industrial duty, how does the Leviton locking connector's grade compare to the Eaton alternatives?
The Leviton locking connector is an industrial grade device built for high-vibration, high-traffic industrial power distribution. Among the Eaton comparables, the 7506 L1-15 connector is classified extra heavy-duty industrial specification grade, while the Arrow Hart Ultra-Grip L14-20 is a commercial grade device. If your specification calls for industrial duty, the Eaton L14-20's commercial classification is the point to check against your submittal, even though its L14 configuration is the closest family match.
