Cooper Wiring Devices 7464N – Frequently Asked Questions

1) Will this locking connector fit the cord jacket on my equipment?
The cord grip accepts jacket outside diameters from 0.68 to 1.13 inches. Measure the jacket OD on your cordage, not the conductor size, and if it falls under 0.68 inches the clamp will not grip it properly.
2) Two-pole versus three-pole locking connector, which do I need?
This Cooper device is two-pole. That suits a single circuit, hot and neutral or two hots, with the equipment grounding conductor on the separate ground terminal. If you are feeding a 125/250V load that needs both legs and a neutral, step up to a three-pole four-wire device such as the Leviton 2413, or a four-pole five-wire like the Leviton 2323 for three-phase wye.
3) What is a comparable two-pole locking connector if the Cooper 3762 two-pole nylon connector does not fit my cordage?
The Eaton Arrow Hart Ultra Grip Locking Connector, part number L530C, is a two-pole three-wire nylon locking connector in the L6-30 series rated 30A. It shares the Cooper connector's two-pole configuration and nylon housing, so it suits the same industrial twist-lock duty while carrying the L6-30 configuration. The Cooper unit accepts #10-6 AWG conductors and cord diameters of 0.68 to 1.13 in, so match your cord jacket against the Eaton before swapping.
4) I need a 125V 30A L5-30 twist-lock connector instead of the Cooper two-pole unit - what should I order?
The Leviton 2313 is a 3-wire 2-pole industrial grade locking connector rated 125V 30A in the NEMA L5-30R configuration. The Cooper connector is a two-pole industrial connector offered in a 125 volt and a 250 volt version, but if your equipment cord terminates in an L5-30 plug the Leviton 2313 is the matching configuration.
5) Is a nylon body good enough for a plant floor, or should I use metal?
Nylon is the housing material here, and it is a standard industrial-grade choice: it takes impact, resists corrosion and will not conduct. Cooper lists the connector for industrial application. If your spec calls for a non-metallic body specifically, Bryant's 71020NC in the 7 Series is another non-metallic locking connector.
6) What else could I use instead of the Cooper 3762 locking connector?
Staying with Eaton, the Arrow Hart Ultra Grip L6-30 connector is also a two-pole three-wire nylon device. The Leviton 2313 is an industrial grade two-pole three-wire connector in NEMA L5-30R at 125V 30A. Whichever you choose, the NEMA configuration has to match the plug or receptacle it mates with, since locking blade patterns are not interchangeable.
7) Can I use this connector on a portable cord set for a piece of machinery?
That is a typical use. The twist-lock engagement keeps the connection made under vibration and repeated handling, the cord grip covers 0.68 to 1.13 inch jacket diameters, and the terminals take #10 to #6 AWG, which is the range most portable machine cords fall in.
8) What is the difference between the Cooper two-pole locking connector and the Eaton 7506?
The Eaton 7506 is an industrial grade L1-15 locking connector in black, built to an extra heavy-duty industrial specification grade. The Cooper unit is a two-pole nylon connector for industrial use that accepts #10-6 AWG conductors and comes in 125 volt and 250 volt versions. The L1-15 configuration on the Eaton is a smaller 15A pattern, so the two are not interchangeable at the plug face.
9) Is a Leviton 2323 a substitute for the Cooper two-pole locking connector?
No. The Leviton 2323 is a 5-wire 4-pole industrial grade locking connector rated 20A, which is a four-pole device for three-phase or multi-wire circuits. The Cooper connector is a two-pole device. They look similar as twist-lock bodies but the pole count and blade pattern differ, so they will not mate with the same plug.
10) If I am standardizing a plant on industrial grade twist-lock connectors, which options line up with the Cooper two-pole unit?
The Cooper two-pole connector is built for industrial application with a back wiring termination and nylon housing. Within the same industrial grade tier, Leviton offers the 2313 (3-wire 2-pole), the 2413 (4-wire 3-pole, 125/250V), the 2323 (5-wire 4-pole, 20A) and the 2423, all industrial grade, and Eaton offers the 7506 at extra heavy-duty industrial specification grade. Choosing within one family lets you keep a consistent grade across pole counts while matching each circuit to its NEMA configuration.
11) Does back wiring mean I can terminate this connector without wrapping conductors around screws?
Right. Termination is back wiring, so conductors land straight into the terminals from the rear of the body rather than being formed into loops under binding heads. It is faster on a cord end and gives a cleaner strain relief assembly when you are making up a lot of cord sets.
12) Is there a commercial grade alternative if industrial grade is more than my job needs?
The Eaton Arrow Hart Ultra-Grip L1420-C is a commercial grade locking connector rated 20A 125/250V in the NEMA L14-20 configuration. The Cooper two-pole connector is specified for industrial application with a nylon body. The commercial grade Eaton is a different NEMA configuration and pole count, so it fits where the drawing calls for L14-20 rather than as a drop-in for the Cooper.
