Bag of Spare Adapters?

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?

Actually the back of the UMC says 240V max. Uhm, why do you ask?

@Sudre - not directly, you would have to use a transformer.

Hey guys, I've updated my Home Made Adapters document to add a new adapter I found and to add a page of receptacle identification. If anyone runs into a different kind of receptacle that could be useful, post it here. Here's the revised doc.

Anyone knows about adapters to be used in Europe and Switzerland?

shop,

Your work is awesome as usual!

I also have the 6-20 which is not only used in AC units but also computer rooms.

Also, 10-50 which is the old style arc welder (50A) outlet. It looks a lot like the 10-30 dryer plug but has a straight neutral spade instead of the 'L' shaped one. I actually have this outlet at my cabin because the previous owner had an arc welder from before the 6-50 days. Allows me to charge at the same rate as 6-50 or 14-50 with UMC. At some point I will probably just change the outlet to 6-50 but it shows that it is a plug worth having for completeness sake.

There is also a 30A RV generator plug L5-30 (Camco 55333) which you can get as a single piece adapter to your TT-30 in case you ever come across a generator rather than an RV outlet. I have purchased a TT-30 to 14-50 adapter but haven't cut off the 14-50 yet to replace with my 6-50 female. Once I do that, I will use it for L5-30, TT-30, 5-15 and 5-20 using one piece adapters to the TT-30. This will just make it possible to not have to carry a 120V extension cord in addition to the 240V extension cord.

Where did you find the CS6365 plug? I have been using Cooper for my 6-50R (female) ends.

Thanks for sharing all your work with the rest of us. A little bit of work up front can come in handy when you really need a charge!

@gimp_dad - what kind of 6-50 female did you use? An outlet box, or something that integrates directly with a cord? I just searched for "Cooper NEMA 6-50r" and came across this which looks nice:

I didn't need to make a CS6365 adapter since one comes ready made that terminates to a NEMA 14-50 end:

http://cordtec.com/products.asp?id=852

That's one of the nice things about using the NEMA 14-50 as your adapter receiver, it is a common enough plug that there exists ready made adapters for different plugs. On the other hand, the advantage of using the 6-50 is that the extension cord is lighter since it has one less conductor. Also, that female 6-50 end is sleeker than the Camco 14-50 receptacle.

I had heard that the 10-50 is used here and there - sometimes ovens got plugged into it. Where do you anticipate using your 6-20 adapter?

That's exactly the Cooper device I used. I have several of them.

I have no problem with 14-50 receivers as I have a 14-50 to 6-50 pigtail I daisy chain to in order to hook to my 6-50 extension cord. I will buy the same pigtail. Cordtec is who I used for my Marine 50A to 14-50 pigtail.

That link seems to go to a SS2-50P -> 14-50R adapter. I am hoping to find the cleanest simplest path to CS6365P -> 14-50R or 6-50R.

Well, that Cordtec pigtail I referenced above works for both a marine 50A AND a CS6365 temporary power plug. So you may already have the the same pigtail. I doubt they have two so similar.

It turns out the marine NEMA SS2-50 and the CS6365 are almost identical, the only difference being that the CS6365 has a spike in the center. So Cordtec used a plug that works with both power sources.

Excellent news. Glad it will work.

The CS6365 seems to be used by some generators that output in the range of 10kW. Finding one of those might be the easiest way to test the pigtail.

The company I work for has a 480 volt three phase plug and cord temporary setups that we use on large construction jobs. It would not have been very difficult to create an adapter and charge at 277 or 480 single phase while at work. Carrying around a heavy transformer would be annoying.
I will be easier to just run a cord to the 240 volt spider box distribution center.

I haven't looked at the voltage rating on the UMC.... I figured someone here would know.

That's why I was wondering. Anywhere you have 480volts, you are likely to have access to 240v. Let us know what kind of plug is on the 240v outlet on the spider box.

That's easy. I have created the cords to go between the spider boxes many times. I have a few sitting around somewhere. I haven't felt the need to create the adapter yet.

The disadvantage is usually we put around 5 spider boxes on one 50amp run. Charging the car on a spider box circuit would pretty much draw all the power on that branch.

@gimp_dad - be careful with 10-50 outlets. At my grandmother's house (built in the '40s), it had a 10-50 receptacle for the dryer, but the fuse (and presumably wire) was rated only for 30A. So, be sure and check to make sure it really is a 50A circuit before drawing 40A on it.

Yes. First thing I did was check that 1) it was a dedicated run, 2) it was a 50A circuit. Yes and yes. And it is about a 3 foot run to the panel so it is solid.

Of course all this means it would be exceedingly easy to make it into a 6-50 anyway....

@Sudre - there you go, there's my temporary power plug, the CS6365 or CS6364. That ready made pigtail adapter I found is perfect for that as it adapts it to a NEMA 14-50. http://cordtec.com/products.asp?id=852

The guy who sells these from Cordtec just emailed me saying he's already received four orders "all from California" for these adapters in the day or so I've posted the link to that pigtail adapter.

We must have a bunch of boy scouts on this forum, "always be prepared!" :-)

SWEET! thanks shop.

What's involved in converting a NEMA 10-50 to NEMA 6-50?

My Red MS85 will soon arrive. In the process of getting ready, to my surprise, I discovered a 40-amp breaker in the electrical panel labeled 'Welder'. I then scrounged around the garage and found a 10-50 wall plug only 4 feet from the panel.
The plug is labeled as 50 amps, but the breaker on the panel is for only 40.
From what I've read, installing a 6-50, with what I already have, will be the path of least resistance :)

I will have an electrician do the swap, but want to queue the work order correctly.

I would just swap the plug for 6-50 female - and then get the 6-50 adapter from Tesla…

also you could probably have the electrician look at the wire - if it's rated for 40 amps it might be no problem to upgrade to 50 amp circuit at the panel…even it the wire isn't rated for 50 amps a 4-6 foot run should be no problem for any electrician to handle and not too much money...

either way you'll be go to go and have at least a 40 amp circuit - which is good for 32 AMPs of charging happiness - which is 18-22 miles of range per-hour of charge.

or if you're going to pull wire - the run is so short - your panel might be able to handle 60, 80 or 100 AMP circuit and you could then get a HPWC - and have mucho charging lickity split…it all depends on how many circuits are already in your panel - but if you run is short you may be able to upgrade to a much bigger amp system and it shouldn't cost too much in terms of labor or parts (wire).

Thanks,
I did order twin chargers, but don't have a need for an HPWC at this location. I'll just request a)plug swap and b)upgrade to 50 amp circuit.

This is a NEMA 14-50 to NEMA 10-30 adapter. I have used it successfully with our Model S. It allows you to plug your NEMA 14-50 into the old type dryer outlets. These are 30 amp circuits that must be limited to 24 amps in your car, or they will probably throw the breaker. Our Model S appeared to know this automatically and ste the charging rate to 24 amps.

I do not need this adapter and will send it postage paid to anyone in the US for $50.00

In general you sure do have to set your car to charge at the lower 24amp rate when using an adapter like this. The car will default to charging at 40 amps if you use the tesla 14-50 adapter with this adapter.

Update: The existing 10-50 cabling only supported 40 amps. It was cheaper to install a new and separate 6-50 plug on the garage wall then rewire the 10-50. So now I have both a 10-50 40 amp plug and a 6-50 plug on separate breakers. My 6-50's installed with and extra conductor if I want to change to a 14-50. Probably won't as I've decided to go the 6-50 route as my main adapter. And will buy a 25' 50 amp Welders 6-50 extension cord for travel, and build a 14-50 to 6-50 adapter, for charging at RV parks and KOA; at least that's the plan.

I thought about buying one of these Hobart 14-50 to 6-50 adapters
http://www.amazon.com/Hobart-770674-Adapter-Cord/dp/B003J8NMF0/
, but
1. I could not verify how neutral and ground are wired, and
2. I can build one w/ 6-AWG instead of 8-AWG and use the Camco 14-50 plug which has more utility.
Homemade will be bulkier, but Tesla specific.

We are scheduled to receive our MS on 5/13 and counting down.

Prytog,

I have that Hobart adapter. I "ohm'ed it out" with my multi-meter. Neutral is not connected as you would expect. It is each hot to corresponding hot and ground to ground. This is what you want. The reason it is sold by a name brand unlike many other pigtail variants is that it is a perfectly valid wiring. Nothing unexpected should happen as there is no ambiguity about what you have. You just lose neutral which means there is no way of getting 120V if plugged into an RV outlet through this pigtail.

gimp-dad
Thanks,
Maybe I'll just buy that Hobart 14-50 to 6-50 adapter and not build my own. (not going anywhere by motor until delivery 5/13)
Many moons ago, I own a multi-meter. I should probably get another. Any recommendations for a multi-meter, useful for Tesla MS owners?

All you need is connectivity, so anything Radio Shack sells will be sufficient.

Search for a "continuity tester."

By the way, Tesla is now selling a Roadster charger adapter for the Model S. While you can use it with any Model S, only ones with dual chargers will be able to take full advantage of the Roadster charger's 70 amp output.

Shop, thanks for the notice. Just ordered it. My ridiculous obsession with Model S adapters will not allow me to pass this one up. I asked about it back in Aug when I got my car but they would only sell it to Roadster owners in those days.
