L6-30 Power PLug
I am new to this who Power calculation thing, what does the "L" stand
for in the notation "L6-30"?? Does it mean "Locking" or "Leviton" or something else. And what does the "6" means as well? I asusme the "30" is Amps. Any insight on this would be very helpful. I know this is an easy question, but I need help. Thanks all! |

It's called a "NEMA" number, and it describes plugs, outlets, and cord
bodies, to make it easier to match things up wrote in message ps.com... I am new to this who Power calculation thing, what does the "L" stand for in the notation "L6-30"??

Locking, 250 volts, 30 amps
Take a look at www.leviton.com/sections/techsupp/nema.htm (straight blade) and www.stayonline.com/reference-nema-locking.aspx (locking blade) wrote: I am new to this who Power calculation thing, what does the "L" stand for in the notation "L6-30"??

I know this is an easy question, but I need help. Thanks all! The information seems easy to find. I just did a search on "NEMA receptacles". An "L" at the beginning is used for a locking plug or receptacle. The number before the dash indicates a row on a chart, representing different voltages receptacles are designed for: The number additionally indicates the number of poles (current carrying conductors), and wires (total including ground). 1- 120V no ground 2-pole / 2-wire 2- 240V no ground 2-pole / 2-wire 3- 277V no ground 2-pole / 2-wire 4- 600V no ground 2-pole / 2-wire 5- 120V 2-pole / 3-wire grounding 6- 240V 2-pole / 3-wire grounding 7- 277V 2-pole / 3-wire grounding 24- 347V (yes, the number is out of sequence. it was added later.) 2-pole / 3-wire grounding 8- 480V 2-pole / 3-wire grounding 9- 600V 2-pole / 3-wire grounding 10- 120V/240V no ground 3-pole / 3-wire 11- 240V delta no ground 3-pole / 3-wire 12- 480V delta no ground 3-pole / 3-wire 13- 600V delta no ground 3-pole / 3-wire 14- 120V/240V 3-pole / 4-wire grounding 15- 240V delta 3-pole / 4-wire grounding 16- 480V delta 3-pole / 4-wire grounding 17- 600V delta 3-pole / 4-wire grounding 18- 120V wye no ground 120/208V wye 4-pole / 4-wire 19- 277V wye no ground 277/480V wye 4-pole / 4-wire 20- 347V wye no ground 347/600V wye 4-pole / 4-wire 21- 120V wye 120/208V wye 4-pole / 5 wire grounding 22- 277V wye 277/480V wye 4-pole / 5-wire grounding 23- 347V wye 347/600V wye 4-pole / 5-wire grounding 24- 347V 2-pole / 3-wire grounding (see above) The number after the "-" is current capacity in amps. Standard capacities are 15, 20, 30, 50, 60. Not all connectors are made in all configurations. For instance: Locking connectors are defined, but do not appear to be made in NEMA configurations in the 50 and 60 amp sizes. Non-NEMA connectors are in common use, as are Pin and Sleeve type connectors. Straight blade connectors are not defined for voltages above 347V. Locking connectors are not defined for L3 and L4 (277V, 600V). Locking 15A connectors are not defined for more than 3 wires. 30A is the most universal size in locking connectors, available for L5 thru L23. Other special NEMA types: ML-1 125V 15A 2-pole / 2-wire miniature ML-2 125V 15A 2-pole / 3-wire grounding miniature ML-3 125/250V 15A 3-pole / 3-wire miniature FSL-1 28V DC 30A 2-pole / 3-wire grounding FSL-2 120V 400HZ 30A 2-pole / 3-wire grounding FSL-3 120V 3 phase delta 400HZ 30A 3-pole / 4-wire grounding FSL-4 120/208V 3 phase wye 400HZ 30A 4-pole / 5-wire grounding There could be a final "P" for plug or "R" for receptacle. Don't forget "C" for connector body (cable end). A L6-30 is a locking plug or receptacle for 240V (ground but no neutral) at 30A. Hopefully, I got that right Not bad.. :-) -- -- Welcome My Son, Welcome To The Machine -- Bob Vaughan | techie @ tantivy.net | | P.O.

Or their 50A marine inlet series which is similar (and seemingly compatible, but without the center spike on the outlet)? No, they are not. The NEMA standard for 50 and 60 amp connectors seems to have fallen by the wayside.. I have catalogs from 3 different manufacturers from 1988, 1994, and 2004, and the 50 and 60 amp locking connectors appear on a chart in the Leviton 1994 catalog, but are not offered as a product. They do not appear on the chart in either the 1988 or 1994 Bryant catalogs, or in the 2004 Pass and Seymour catalog. In fact, I only noticed them on the chart while I was fact checking my previous post. They do not appear to be offered as a product by P&S, Bryant/Hubbell, or Leviton. I think the reason for this is that the California Standard (CS) patterns had been adopted by mutual consent within the industry, and the problem of using the same connector for multiple voltages had already been resolved before the NEMA standard came along. In addition, there are several different types of locking connector that are used at the 50 and 60 amp level, as well as the 100 amp level, including TurnLock/HubbellLock and IEC309 pin and sleeve type connectors. -- -- Welcome My Son, Welcome To The Machine -- Bob Vaughan | techie @ tantivy.net | | P.O.

Dan Lanciani ddl@danlan.*com ------------------------------------- Found this when doing a google search for something else and figured I'd answer this in case someone else saw it. Hubbell's 50A twist-lock style plugs and connectors are not considered NEMA. They are referred to as "California" standard or style. Here is a link that lists the different style 50A twist lock plug and connectors: http://www.lockingpowercords.com/Cat...onnectors.aspx |
