TM now has several adapters for sale. Is there much benefit to buying some or all of them to have on hand when out on the road?
@gimp_dad and all. Please read my previous post.
Pricee2; It happens to be on the previous page. Give a link to the page, or a page number if you want a response!
@pricee2 - do you have access to an ohm meter? It would be interesting to figure out if they wired it correctly.
I got an email on my 14-50 to TT-30 saying it was wired wrong and they need to rewire it. Apparently they didn't follow shop's directions properly. :-)
That could be the problem. I haven't tried mine yet. I will ohm it out and then swap the leads myself if necessary.
I did Just ohm out the blades on my EVSEadapters.com 14-50 to TT-30 adapter and it does have the neutral from the TT-30 connected to the "wrong" 14-50 hot conductor.
Pricee2, I would check with them to see if you got one of the few that were built wrong.
Gawd, EVSEAdapters, it isn't that hard!
Ok. I decided to go ahead and make my own 6-50 to TT-30 and quit being lazy. I don't have a TT-30 to try it out on but put it through a TT-30 to 5-15 adapter and it worked fine. I used the shop method of connecting 120v hot to the X terminal and neutral to the Y. Should have done it myself the first time.
@shop and gimp_dad Thanks for the replies. I just metered it and it has the hot going to the Y and the neutral going to the X. So I will be calling EVSEadapters Monday.
Good to know you got to the bottom of it. Thanks to shop for figuring all of this out and documenting it.
I did consider taking apart the EVSE adapter and just fixing it but disassembly looked a little complicated. Now waiting for their prepaid label so I can send it back.
I actually don't need it any more now that I have built the pigtail adapter I prefer anyway. My extension cord is 6-50 so I prefer that connector whenever possible.
Btw, that's 2 for 2 ski resorts I've been to whose parking garages have had nema 5-20 plugs handy. These were probably put in for block heaters, but can be used to charge at 16A instead of the 12A Tesla's adapter gives you if you have the right adapter. If you are up for a ski week, and do only a moderate amount of local driving, then these work just fine as a charging solution.
Shop, first of all thanks for compiling the "Model S Home Made Adapter Document". I think I'm set with my NEMA 14-30,10-30 and 10-50 adapters. But, wouldn't you know it, next month we'll be visiting a friend in Upstate NY who only has NEMA 6-50 receptacles available (other than the standard NEMA 5-15). On Amazon I found a convertible NEMA 6-50/6-30 plug which I would (8 gauge) wire to the NEMA 14-50 receptacle. I would wire hot to hot on both blades (I don't think that it matters which), ground to ground. Sounds pretty straight forward to me; but, I don't want to burn down my friend's house or blow up my Sig! Any advise from you or anyone else familiar with building these adapters would be appreciated.
Yes that should work fine. Be aware that Tesla does also sell a 6-50 adapter, but you would then have to be within 20 feet of the receptacle, or buy a 6-50 extension cord, which are readily available.
Thanks shop, I already have a 50' 14-50 extension cord and I want the ability to be more than 20' from any receptacle. I also bought a Camco RV 30M/50F adapter. As per your instructions I will cut off the 14-50 part of the adapter. When I do that will the wires be color coded (Green=ground, white=neutral, red=hot) so I'll be sure I'm making the right connections? Also, will I be able to pigtail a Camco 30F/15M adapter to the TT-30 so I don't have to carry an extra extension with me? Thanks again.
I have no idea how the wires in your particular camco adapter are wired (and they could even change through manufacturing runs), so it always a good idea to use an ohm meter to determine which pins are connected to which wires.
That camco 30F/15M adapter could be used with your TT-30 adapter to plug into a NEMA 5-15 or 5-20 plug and draw 12 amps or 16 amps respectively from it. And yes, that would allow you to not have to use a regular extension cord in those cases, and you could just use your 50a extension cord.
shop, you are absolutely the best!

a document discussing all the adapter's in the picture hosted here:
I do _NOT_ consider this an alternative/replacement to shop's excellent document! At most I would humbly consider it a companion to shop's document. If there are any error's or omissions I'll do my best to update the document with feedback.
Cool! Love the pic and docs.At some point, I should document how I built my dual 120V adapter box for regular 120V receptacles and TT-30 receptacles. But I don't know how useful such a box is.
I've been re-reading this thread in detail while I await my Friday delivery. It seems much of it may be moot for me since the Tesla adapters are readily available. At home I am charging from a 14-50, and on the road I will try to use public charge stations. My only concern is in visiting relatives. I assume they will have a 14-30 or 10-30 dryer plug, but it may not always be in reach of the car. I prefer to use off-the-shelf solutions rather than build my own. For the 14-30, I found this extension cord on Amazon. Any problem with using this?
I haven't found a solution yet for 10-30 installations. Anyone found an existing extension cord for these?
That cord is not a 14-30 extension cord, it is for a locking connector. Finding 14-30 or 10-30 extension cords is very hard, although I remember someone finding one of them a while back. You can make your own extension cord too. That's the point of the home made adapters, you can just use a single RV 50 amp extension cord with any plug.
Glad you pointed that out - I didn't see the 'L' before 14-30 and probably wouldn't have known what it meant anyway.
Here was the link I was looking for, a 10-30 extension cord. But as others have pointed out, you have to figure out if you need a 14-30 or 10-30.
Couldn't I buy a 14-50 extension cord and remove the neutral pin on the plug end? Then it would fit 14-30s and 14-50s. I realize I'd have to label it "For Tesla Charging Only", but this would work, right?
Of the many adapters discussed in this thread, I haven't seen any mention of a NEMA 14-50R to NEMA 6-50P (unless I missed it). The purpose of such an adapter would be to use a 14-50 RV extension cord with the Model S to plug into a welder outlet. I also didn't see this adapter on EVSEadapters.com. Does anyone know whether such an adapter can be purchased anywhere? Am I missing something as to why it does not appear to be available? I have seen adapters going the opposite direction, i.e., 6-50R to 14-50P. Thanks.
the easiest thing to do is to build a NEMA 10-30/14-30P to 14-50R plug…cause then all you need is a 14-50 extension cord
using shop's excellent document you can find NEMA 10-30/14-30 "wire/pig-tails" - a plug on one end and bare wire on the other - you then buy the Camco RV 14-50 50AMP connector (female/14-50R) and wire it up…
My recommended "recipe" for any type of plug is:
a) find a "connector/plug" already made with the type of plug you need - even if the other end is the "wrong" type of plug/receptacle … b) chop the "wrong" end off the wire - strip the wire leaving the "right" plug-receptical attached c) using the stripped wire attach it to a Camco 55343 RV 50 AMP female connector - this is a NEMA 14-50R connector (R = receptacle/female connector)
d) Now you can use the stock Tesla 14-50 connector for the mobile charger e) dial the charging AMP's in the car down to 80% of the rated breaker for the plug you are currently using f) by converting everything to a NEMA 14-50R connector you can then purchase a NEMA 14-50 extension cord…
NOTE: there are two basic choices here - NEMA 14-50 or NEMA 6-50 - extension cords are easily obtainable for both types of plugs/receptacles…
your only choice here is length and type of plug
when building your "adapters/pigtails" build them to match your extension cord, and then you can use the Tesla 14-50/6-50 adapter for all types of plugs…
NEMA 14-50P to NEMA 6-50R pigtail - http://www.amazon.com/Hobart-770674-Adapter-Cord/dp/B003J8NMF0/ref=pd_bx...
careful reading of the following documents will tell you all you need to know
changes to my charging kit that I carry with me:
I have ditched my 120v NEMA 5-15 extension cord in favor of a 20AMP NEMA 5-20 extension cord - with the proper pig-tail or adapter this one extension cord can be either a NEMA 5-15 cord or a NEMA 5-20 cord
I have also purchased a NEMA L5-30 adapter to deal with a plug I encountered at a motorsports venue last weekend
I ditched the home made NEMA 5-20 adapter shop's document made in favor of the new Tesla 5-20 adapter (thanks shop! sorry shop!)
NEMA 5-15 to NEMA 5-20 adapter pig tail http://www.amazon.com/gp/product/B00439KIF6/ref=oh_details_o00_s00_i00?i...
NEMA 5-20/5-15 Extension cord http://www.amazon.com/gp/product/B000HEC2DW/ref=oh_details_o00_s00_i01?i...
when dealing with a "normal" 5-15 house hold plug this extension cord will work with the adapter listed above
NEMA L5-30P to NEMA 5-20R/5-15R - found in certain outdoor/wet locations this is 120V/30AMP connections
Not sure the 30AMP's does you any good cause Tesla software doesn't allow AMP settings above 16 amps for 120V power sources

I forgot to post the link the NEMA L5-30 pig-tail/adapter - here it is…
I don't feel up to building the adapter; I'm looking to purchase one. However, I think you misread my post. I want a 14-50R to 6-50P adapter or pigtail. That is because I want to use a 14-50 extension cord and plug into a 6-50 welder outlet. Unless I'm missing something, none of the links or items you described will do that.
@DouglasR - just like the 10-30 adapter, you aren't likely to find one, because you are either tying the neutral conductor to ground or leaving it unconnected -- either case is dangerous in different scenarios, and the only safe use of such an adapter is with something that leaves the neutral unconnected when plugged into the 14-50 end. You are more likely to find the other direction - get a 6-50 extension cord, and an adapter to plug the 6-50 plug into a 14-50 outlet (safe, since it just doesn't use the neutral connector), and then use the 6-50 adapter on the Tesla UMC.
Or, you can build your own / find someone willing to build a custom cable for you.
