Leviton CS8164C – Frequently Asked Questions

1) What is the difference between the CS6364C, CS8364C and CS8164C versions?
They differ by voltage and phase. CS6364C is 125/250V single phase, CS8364C is 250V three phase, and CS8164C is 480V three phase. All three are 50A, 3-pole 4-wire California Style locking connectors. The configurations are not interchangeable, so match the one on the equipment or cord you are connecting to.
2) I need a 50A locking connector for a generator tie-in. Can I use a lighter duty 20A or 30A locking connector instead?
Not if the circuit is 50A. This Leviton California Style connector is rated 50A, and a 20A or 30A device cannot be substituted on a higher-current feeder. The Eaton Arrow Hart Ultra Grip L6-30 and the Pass & Seymour Turnlok L6-15 are lower-amperage NEMA locking connectors for 30A and 15A circuits respectively, not replacements for a 50A CS device.
3) Can a NEMA L14-20 connector be used in place of a CS6364C California Style connector?
No. The Leviton CS6364C is a Non-NEMA California Style 4-wire, 3-pole locking connector rated 125/250V, 50A, and its blade pattern will not mate with NEMA locking devices. The Eaton Arrow Hart Ultra-Grip L14-20 connector is a NEMA L14-20 device rated 20A, 125/250V, so it shares the voltage but not the configuration or the current rating. Use an L14-20 connector only where the mating plug and inlet are also NEMA L14-20.
4) Is a 3-pole 4-wire CS connector grounded?
Yes. In a 3-pole 4-wire device the fourth wire is the equipment ground, so you get three current-carrying poles plus ground. On the CS6364C that means two hots and a neutral at 125/250V plus ground; on the CS8364C and CS8164C the three poles are the three phase conductors plus ground, with no neutral.
5) Is this connector rated for stage and event power distribution?
Yes, entertainment, stage and event power is one of the intended uses, along with industrial and commercial distribution, temporary and portable power, and generator or backup hookups. It is built to Industrial Grade, which is the construction level for repeated connect and disconnect cycles in the field.
6) Is there a lighter-duty locking connector for a 15A 250V drop?
Yes. The Leviton California Style connector is a 50A Industrial Grade device intended for heavy power distribution. For a 15A, 250V drop, the Pass & Seymour Turnlok NEMA L6-15 locking connector is the corresponding device, built in EHU nylon. It is a NEMA configuration, so it will not mate with California Style plugs.
7) Which locking connector matches the Leviton California Style unit on industrial-grade construction?
The Leviton CS6364C California Style connector is Industrial Grade. Among NEMA-configured alternatives, the Eaton L1-15 locking connector is rated Extra Heavy-Duty Industrial Specification Grade, so it is built to a comparable duty level, but it is an L1-15 configuration rather than a 50A California Style interface. Choose on the interface the opening requires first, then on grade.
8) What is the difference between the Leviton California Style connector and Bryant's locking connectors?
The Leviton unit is a Non-NEMA California Style connector covering CS6364C at 125/250V 1-phase, CS8364C at 250V 3-phase, and CS8164C at 480V 3-phase. Bryant's 71020NC is a non-metallic NEMA locking connector in the 7 Series, and the 70520NCC is a 705 Series locking connector, both NEMA configurations. The Bryant devices will not intermate with California Style plugs or inlets.
9) What does Industrial Grade mean on a Leviton locking connector versus a commercial grade device?
Industrial Grade construction is specified for demanding, repeated-use power connections rather than occasional service. For comparison, ZenSupply's Eaton Arrow Hart Ultra-Grip L14-20 connector is listed as Commercial grade, while the Eaton L1-15 connector is listed as Extra Heavy-Duty Industrial Specification Grade. If a spec sheet calls for industrial grade wiring devices, a commercial grade part will not satisfy it.
