Eaton CS6377 – Frequently Asked Questions

1) Will an Eaton CS6377 flanged inlet mate with a standard NEMA L5-30 or L14-50 locking connector?
No. The CS6377 is a California Standard (non-NEMA) locking device, so it only mates with California Standard 50A 125V two-pole, 3-wire locking connectors and plugs. NEMA twist-lock configurations use a different blade pattern and will not engage. If your cord set ends in a NEMA locking connector, you need a NEMA-configured inlet instead.
2) What size conductors can I land in the Eaton CS6377 50A inlet?
Terminals take #10 through #6 AWG, back-wired, across three wires (two hot poles plus ground). That range covers the #6 copper a 50A feed typically calls for, and it will still clamp down on #8 or #10 if the inlet is fed at a reduced ampacity.
3) Can the CS6377 California Standard inlet be used on a 250V circuit?
No. It is rated 125V only, two-pole 3-wire. For 240V equipment you need a 250V-rated California Standard device instead, and the mating connector has to match that same rating and configuration.
4) How much room do I need to cut out and clear behind a CS6377 flanged inlet?
The device measures 3.5 in high by 3.5 in wide with a 4 in length/depth. Plan the flange footprint on a 3.5 in square and allow the 4 in dimension behind the mounting surface, plus bending room for the #6 AWG conductors landing on the back-wired terminals.
5) Will this locking inlet hold up outdoors in freezing weather or next to hot equipment?
The operating range is -40 to 105 C (-40 to 221 F), so cold storage, unheated yards and hot machine rooms are all inside spec. The face and body are glass filled nylon, which resists impact and corrosion better than standard thermoplastic, and the device includes a lid to cover the inlet when nothing is plugged in.
6) What is the difference between a flanged inlet like the CS6377 and a receptacle?
A flanged inlet has male blades and mounts to the outside of a machine, generator, or enclosure so power feeds into the equipment from a cord set. A receptacle has female contacts and feeds power out. If you are building a portable machine or skid that gets energized by a shore cord, the inlet is the part that goes on the equipment; the cord gets the mating connector.
7) Is the Eaton CS6377 inlet listed for code-compliant commercial installation?
It carries a cULus Listing, which covers it for both US and Canadian installations. It is also built to California Standard requirements and carries an extra heavy duty device grade, the construction level intended for industrial duty and frequent plugging cycles.
8) Does the CS6377 give me an equipment ground, or is it just two hots?
Three wires total on a two-pole device, which means two current-carrying poles plus a grounding conductor. That is the standard 50A 125V California Standard arrangement, and the ground has to be landed for the locking connection to be code compliant.
9) What exact part number do I order for the Eaton Arrow Hart 50A California Standard flanged inlet?
Order Eaton Arrow Hart CS6377. It is a single configuration: 50A, 125V, two-pole 3-wire California Standard locking flanged inlet in a steel color glass filled nylon body. There are no finish or amperage options to specify.
