Eaton L1420-C – Frequently Asked Questions

1) What size cord and wire can I terminate in this L14-20 connector?
The connector takes #16-12 AWG conductors and clamps cord jackets from 0.25 in to 0.69 in diameter (6.4 mm to 17.5 mm). That covers typical 12/4 and 14/4 SO or SJOOW cord for a 20A 125/250V cordset. Conductors land by back wiring, so you strip, insert, and tighten from the rear of the body.
2) Is this the female connector or the male plug?
It is the connector, the female end that goes on a cord and accepts a matching L14-20 plug. If you need the male end for the other end of the cordset, you want an L14-20 plug instead, not this part.
3) My cord has a neutral plus three hot legs - can I use the Eaton L14-20 connector?
No. The Eaton Arrow Hart L1420-C is a three-pole, four-wire grounding device in the NEMA L14-20 configuration, which covers two hot legs, a neutral and a ground. For a five-wire circuit you need a four-pole device such as the Leviton 2323, an industrial grade 5-wire 4-pole locking connector rated 20A - the same amperage as the Eaton L1420-C but one extra pole.
4) Can I use this twist-lock connector outdoors or in an unheated building?
Its rated operating range is -20 to 60 C (-4 to 140 F), so cold storage, unheated shops, and outdoor temporary power are within spec. The body and face are thermoplastic, which holds up to impact and chemical splash on a jobsite. It is not a watertight device, so for wet-location use it still needs a weatherproof cover or boot.
5) Is a commercial grade locking connector good enough for industrial machinery, or should I buy industrial grade?
This Eaton Arrow Hart is a commercial grade device listed for industrial applications, with brass contacts and a safety grip locking feature to resist accidental pull-apart. For hard-use plug/unplug cycles on production equipment, some buyers prefer a true industrial grade body: Leviton's industrial grade locking connectors are the step up, including the 2413, a 4-wire 3-pole 125/250V connector in the same voltage class.
6) I need a 30A twist-lock, not 20A. Is this the wrong part?
Yes, this one is limited to 20A. For a 30A circuit at 125V, the Leviton 2313 is a 3-wire 2-pole L5-30R connector. Note the pole count differs: L14-20 is three-pole for 125/250V split phase, while L5-30 is two-pole 125V only, so match the configuration on your outlet rather than just the amperage.
7) We standardize on industrial grade wiring devices across the plant - is the Eaton L1420-C a fit?
The Eaton Arrow Hart L1420-C is a commercial grade device intended for industrial applications, with a thermoplastic body and an operating range of -20 to 60 C (-4 to 140 F). If your specification calls out industrial grade specifically, the Leviton locking connector family - the 2313, 2323, 2413 and 2423 - is listed as industrial grade, with the 2413 matching the Eaton's three-pole 125/250V configuration.
8) How does the Bryant 7 Series non-metallic locking connector differ from the Eaton Arrow Hart L1420-C?
Both are NEMA twist-lock connectors with non-metallic housings - the Eaton L1420-C uses a thermoplastic face and body with brass contacts, and the Bryant 71020NC is a 7 Series non-metallic NEMA locking connector. The Eaton is specified to the L14-20 configuration at 20A, 125/250V with a safety grip locking plug feature, so when you are matching an existing L14-20 cordset, confirm the Bryant unit you select carries the same configuration.
9) Is the Leviton 2423 a drop-in replacement for the Eaton Arrow Hart L1420-C?
Treat it as a configuration check rather than a drop-in. The Leviton 2423 is an industrial grade locking connector supplied in black/white, while the Eaton L1420-C is a black thermoplastic device specified to NEMA L14-20 at 20A, 125/250V. Match the NEMA configuration of the mating plug before substituting, since a locking connector only mates with its own configuration.
10) What part number do I order for the Eaton Arrow Hart L14-20 connector, and what color is it?
Order Eaton Arrow Hart MPN L1420-C. It is black, a single-model item, so there are no finish or color choices to specify.
11) What is the difference between the Bryant 705 Series and the Bryant 7 Series locking connectors when cross-shopping the Eaton L14-20?
They are two different Bryant twist-lock families: the 71020NC is a 7 Series non-metallic locking connector and the P468365 is a 705 Series locking connector offered in NEMA twist-lock configurations. The Eaton Arrow Hart L1420-C is a single specified part - three-pole, 20A, 125/250V, NEMA L14-20, back-wired for #16-12 AWG - so if you are replacing an L14-20 device, verify the Bryant series part you pick is ordered in the L14-20 configuration.
