I need the NEMA #
« on: January 13, 2011, 03:09:20 pm »

Here I am again feeling dumb because another electrician asked me for a specific part #.  We have another event planned and the local electrical supplier is renting a large generator to the client and wants to know what kind of outlets to provide for us and I quote "I need the NEMA # such as L6-50"   I can never remember the NEMA # of the ever popular Hubble twist lock connector that most of us use on the typical 6/4 SO cable.  Here is a pic lifted from the Motion Labs site.



Do these connectors have a NEMA #?

I don't know if it's an official Nema #, but the common designation is CS-6365 for the male,
CS-6364 for female.    You can google it and find a lot of suppliers who sell a Marinco version for about $30.

CS = California Standard

Gene, I don't think that connector has a NEMA number, either.

yes, it does have a NEMA number...

L14-50  =  3-pole 4-wire 125/250V 50A locking devices

L14-50R  =  receptacle

L14-50P  =  plug

Electrical Suppliers often take pride in making things complicated and I'm sure they chuckle amongst themselves when we leave.   Googling those numbers can take you to many sites with conflicting drawings associated with those numbers mentioned.  Mr. Electrical Man says that every plug/receptical has a NEMA # by law.   So even though I have emailed them a hi-rez photo of all my various tails - plugs - adapters - etc. they still need a NEMA #.  For now we've settled on a 50 amp range plug.

Gene -

James G nailed it.  Google the #s & make your choice.

L14-50 is a different animal, not what you have in your pic.

Prices for these can vary widely, your local electrical supply house may or may not have great prices, but should certainly know what you're looking for.

Well, the 50 amp range plug does have a NEMA number.
I know of no law that requires NEMA numbers for all connectors.  My Hubbble Chart
 https://www.hubbellnet.com/max_htm/tech_stuff/NEMA/back.html#TOP
shows a section of "Non NEMA" connectors. However, that is not to say that for certain types of installation they are not required - residential for example.
I have never found a CS connector with a NEMA number.
My electrical supply will happily look them up as CS connectors. Perhaps you need to check in with another supplier?

Those are Non-Nema.
They are "California Style" CS locking plugs and connectors.

it's relatively easy to understand the confusion considering there are so many variables involved;  locking, non-locking, voltage, ampacity, etc.

my bad, i based my previous post on your statement, "typical 6/4 cable use" rather than the actual image provided.  the most common application that i see for 6/4 is 50A 125/250V, for rac-pacs, spider boxes, etc.   

upon further examination, i see that the connector in the image is actually the 50A 250V 3 California Standard Series.
in which case, are non-nema and the model numbers are as follows:
CS8364C connector, CS8365C plug, CS8369 receptacle

The picture Gene showed is NOT an L14-50.

The event went well.  After all the fuss about NEMA #'s and not knowing what kind of connectors these ever popular "California connectors" really are - the large rental generator had 3 of them mounted on the side labeled 240 single phase 50 amp.  We used the range plug they had hanging from a 10 foot drop because that added to my 5 foot adapter plus my extra 50 feet of 6/4 as well as the aforementioned 100 feet of 6/4 all added up to 165 feet and that brought us to where it had to go.  Never mind that I told each person I spoke to that we had to be no more than 100 feet away.  My cheap rack rider voltage display readout never dropped below 116 and was pretty steady at 117 all night.   How can the generator rental person not recognize the outlets on their generator from the pics I supplied them in my emails all the while acting as if he had never heard of such connector?!

OK just one more and I'll leave this one alone.  Here's somebody's phone video http://www.youtube.com/watch?v=IvZu8KRhaDE

I prompt him to credit us (2:30) while he announces all manner of sponsor and helper and then the "star" arrives.  Unfortunately my my hippity-hoppity rapper-dancer knowledge is nill so I had never heard of Omarion.

The rig was:

A Shure wireless  Beta 58

A&H MixWiz with elcheapo Behringer 4 ch comp  (no master EQ just channel EQ)

my ground stack rig...

3 powered tops per side - 1x15 and 2 - 2x15+2"
2  3x15 powered subs per side
2  2x18 and 4 single 18 powerd by a Crown Xti 6000

Rick Ramsdell shared the joy and brought his small line array 8  1x10" per side powered by various Crown Xti 4000 and 2000 and the majority of the bass was made by 4 of his 21" Sub Engines powered by the big half of 2 old Crown Macrotech 36x12 using a DriveRack crossover.

The 2 systems combined are not perfect but they do sound pretty good together and certainly achieve the thunder needed for this event.  The DJ was brutal and kept the MixWiz consistently in the top yellow LEDs with the occasional red clip light flickering on various Xti amps.

Are you sure it is 3 phase? Most CS I see are single phase 120/240v connectors. The ones I have sure are.

yes, i'm sure, the connectors in the OPs image are 3-phase. 

at a glance, the actual configuration is easily mistaken and improperly identified.   upon closer examination of the image, the contact and index tab configuration of the twist-lock device is what determines it's identity. 

you can compare the connectors here;  single-phase and three-phase.

for the sake of further comparison, the single-phase version would look like this:


there is a difference...
