Leviton C2623 – Frequently Asked Questions

1) What is the difference between the 2-pole and 4-pole options on the Leviton locking connector?
Two devices are sold here. The 2-pole choice is the C2623, a 2-pole 3-wire L6-30R rated 250V 30A. The 4-pole choice is Leviton 2443. Pick by the cord cap or receptacle you are matching: a 3-wire 250V single-phase circuit takes the C2623, while a 4-pole device is for a four-wire circuit. Order by the part number, not just the pole count.
2) What are the alternatives to the Leviton C2623 L6-30 locking connector from other brands?
The closest cross-brand equivalent we carry is the Eaton Arrow Hart Ultra Grip locking connector in the L6-30 series, two-pole three-wire, 30A, with a nylon body. If your circuit is 250V but only 15A, the Pass & Seymour Turnlok L6-15 connector is the smaller-configuration match. For a 125/250V four-wire circuit instead, the Eaton Arrow Hart Ultra-Grip L14-20 connector is a different configuration entirely and will not mate with L6-30 devices.
3) Can I use the C2623 on a 120V circuit or a 50A feeder?
No on both. The C2623 is rated 250V, 30A, single phase. Use it on a 30A two-pole 250V branch circuit only. A 120V load needs a 125V configuration such as L5-30, and a 50A load needs a device rated for that current. Overrating the circuit breaker beyond 30A on this connector is not acceptable.
4) What is a direct equivalent to the Leviton C2623 L6-30R locking connector from another brand?
The Eaton Arrow Hart Ultra Grip Locking Connector, 30A, Two-Pole Three-Wire, Nylon is the closest match. It is listed in the L6-30 series, the same NEMA configuration as the Leviton C2623, and shares the 30A two-pole three-wire arrangement. The Leviton is an Industrial Grade device rated 250-Volt, 30-Amp, 1-Phase in a Black/White housing; the Eaton uses a nylon body. Both are twist-lock connectors, so a cordset built for one lands on the same mating pattern as the other.
5) I only need 15 amps at 250 volts, not 30 - what should I use instead of the Leviton L6-30R connector?
Step down to the Pass and Seymour Turnlok NEMA L6-15 Locking Connector, rated 15A 250V in an EHU nylon body. It keeps the same 250-volt two-pole three-wire service as the Leviton C2623 but on the L6-15 blade pattern, which will not mate with an L6-30 plug. Match the connector to the plug on the cord, not to the circuit alone - the Leviton is L6-30R and only accepts L6-30 plugs.
6) My generator cord is 125/250V four-wire - can I use the Leviton locking connector?
No. The Leviton C2623 is a 250-Volt, 30-Amp, 3-Wire 2-Pole device in the NEMA L6-30R configuration, which carries two hots and a ground with no neutral, so it cannot serve a 125/250V four-wire load. For that service use the Eaton Arrow Hart Ultra-Grip Locking Connector, 20A 125/250V, NEMA L14-20, which is the four-wire pattern generator cordsets commonly use. The Eaton is a Commercial grade device; the Leviton is Industrial Grade.
7) Is this connector rugged enough for a machine shop or job-site cordset?
It is built to Industrial grade, with a twist-lock connection that resists vibration and accidental pull-apart. Typical uses are industrial and commercial power distribution, machine shops and manufacturing, portable power equipment and cordsets, and temporary job-site power. For high-cycle plug-and-unplug duty, the locking body is what keeps the connection made.
8) Is a locking connector the female cord end or the receptacle you mount in a box?
A connector is the female cord-mounted end of a cordset. It goes on the end of a flexible cord and accepts a plug or a flanged inlet. If you need a device mounted in a wall box or panel, that is a receptacle or flanged outlet, not this part. For the male cord end, order the matching plug.
9) Why is a polarized 2-pole 3-wire connector specified instead of a straight-blade device?
Two reasons. The polarized 3-wire 2-pole body only mates one way, so hot, hot, and ground land in the same places every time. And the twist-lock action means a machine or portable load cannot be knocked loose by cord drag or vibration, which is the failure a straight-blade 250V device is prone to on moving equipment.
10) I need an industrial grade locking connector but not the Leviton. What else is industrial rated?
Eaton's L1-15 locking connector is catalogued as Extra Heavy-Duty Industrial Specification Grade, in black. Bryant also offers locking connectors in the 7 Series (non-metallic) and the 705 Series. Note the Eaton L1-15 is a different NEMA configuration from the Leviton C2623's L6-30R, so it is an alternative on grade, not a substitute on the circuit.
11) Is there a non-metallic body alternative to the Leviton industrial locking connector?
Yes - the Bryant 71020NC 7 Series Non-Metallic NEMA Locking Connector is a non-metallic housing twist-lock device, and Bryant also offers the 70520NCC in the 705 Series. The Leviton C2623 is an Industrial Grade twist-lock connector in a Black/White housing. Confirm the Bryant NEMA configuration matches the L6-30 pattern you are wiring before ordering, since body material does not change blade compatibility.
12) For a high-cycle machine shop disconnect, how does the Leviton compare to Eaton's heaviest locking connector?
The Eaton 7506 L1-15 connector is built to an Extra Heavy-Duty Industrial Specification Grade, a step above standard industrial construction, but it is an L1-15 configuration. The Leviton C2623 is an Industrial Grade twist-lock connector carrying 250-Volt, 30-Amp, 3-Wire 2-Pole on the L6-30R pattern, which is the rating machine shop and portable equipment cordsets at 30A typically need. If your load is 250V 30A, the Eaton L1-15 is not an option regardless of its grade.
13) What color is the Leviton C2623 locking connector body?
Black and white housing, which is Leviton's usual visual cue for its industrial grade locking line and makes the device easy to pick out on a crowded cord reel or panel wall.
