Higher charge rate is better for battery health and pack balancing I do believe. Might want to get something more permanent.Glad I was able to pick up the 14-30.
We unplug our dryer, and run the 14-30 w/ UMC from our laundry nook out to the garage. Works well when we need a higher charge rate.
link, that gives that belief?Higher charge rate is better for battery health and pack balancing I do believe ....snip....
All the Jeff Dahn lectures, efficiency of AC to DC conversion, anecdotal evidence from owners with dual-chargers that charge at 40amps and up have less overall degradation (adjusted for supercharger use).link, that gives that belief?

:ast Spring I saw the 14-30 adapter listed in the owners manual and my electrician installed a 20amp circuit in my garage. I have been happily charging at 30 amps ever since.If you aren't already up to speed: Trying to find a Tesla NEMA 14-30 adapter
The short story is that there is still a need for the NEMA 14-30 adapter that Tesla has discontinued. This need is increasing both as a percentage of current ownership that is realizing the 14-30 is useful, and as a total number of new owners where a 14-30 is their fastest/only option.
The longer story is owners and reservation holders are finding themselves in a couple of different situations where there is a legitimate need for the NEMA 14-30 adapter.
1. Their existing wiring in the home or the break box doesn't currently allow for a 14-50 connection to be run at all, or the cost to do so just isn't economical.
2. Those that have gas dryers and therefore the 14-30 is not currently in use, extending that outlet to where the car is parked is a reasonable solution for them as an alternative to a brand new run back to the breaker-box.
3. Owners and future owners find themselves traveling to locations that only have 14-30 connections (I'm looking at you in-laws). Spending the night somewhere, even with a 5-20 adapter just doesn't get the necessary range to continue on a journey or return home. 17mph from a 14-30 is far more useful/acceptable even if not ideal.
So the motivation behind this poll is some real world experience. I came across a couple forum members that posted about having trouble finding a NEMA 14-30. For whatever reason, their local service centers did not have any in stock and were either unwilling or unable to transfer inventory from another service center to their own. So I called my local service center, and sure enough they had a couple. I purchased them, boxed them up and shipped them out to the owners and charged them only the cost to do so. Well, that was 18 adapters ago, within just a 3 week period. Word got out that I was willing to do the legwork to find them and I've been helping where I can. Currently, I have 9 more people waiting to purchase adapters if I can locate them. But unfortunately, it appears as though the well may have run dry. The remaining stock at service centers is being used for warranty replacements for existing owners that may have a 14-30 adapter that goes bad in the future. As a 14-30 owner/user, I support that mentality.
All that to say this, Tesla is currently unaware of this need and so hopefully, an online poll will act as a vehicle to communicate this message to them. They already have the specs and the production figured out. While I'm sure it's not just as easy as flipping a switch, I do expect the hard work is already done. So please comment, please vote. You will be helping currently owners who need this adapter, you will be helping future Model 3 owners that will need this adapter, and you will be helping yourselves if you ever find yourself needing this adapter. The NEMA 14-30 is the 2nd most useful adapter I have at the moment so I'm not just an un-paid actor, I'm also a client.
That's great! I would have expected your garage to catch fire if you were charging at 30 amps on a 20 amp circuit!:ast Spring I saw the 14-30 adapter listed in the owners manual and my electrician installed a 20amp circuit in my garage. I have been happily charging at 30 amps ever since.

You are right that it would work. As a matter of fact, I had already done that with my hacksaw here at home and cut the neutral pin off my 14-30 adapter so I can use it with the 14-50 extension cord I have.If anyone from Tesla is reading this, here is a suggestion: Elide the neutral blade from the 14-30 adapter plug. It would allow the 14-30 adapter to also plug into a 14-50 (and the very rare 14-60). Yet since it will always set charging to 24 amps max, it is safe in all cases. It would also save a few pennies on manufacturing costs.
Yes. Anybody with a hacksaw and a vise can make the modification in a couple of minutes. I did:You are right that it would work.

But I would expect that it will be a no-go to think that Tesla could officially sell them that way. Principally because NEMA is an official standard that defines what things are called. And Tesla would not be allowed to sell an adapter that is referred to as a 14-30 if it does not conform to the 14-30 standard and have that pin. The small company EVSEAdapters has a few adapter parts and extension cords that they refer to as "14-XX", which are missing that neutral pin, as you suggest, so they can work in any of the 14-30, 50, 60 outlets.
... I use it on my home 14-50 outlet as well as with the TT-30P to 14-50R adapter that I use with "30 amp" RV pedestals at campgrounds, so that it automatically limits current to 24 amps. Works fine.
That is a clever way to use a readily available three wire extension cord!I actually do it the other way around. I bought a TT-30 adapter from evseadapters. Then use TT-30 parts and cables - both at 120V and 240V (with the 6-30 in my garage). The off-the-shelf TT-30 extension cord I bought is rated at 600V, and only three conductors instead of the four that would be needed for a 14-series version. So cheaper, lighter, and much easier to handle.
Why the vice? Use your hand and live on the edge.Yes. Anybody with a hacksaw and a vise can make the modification in a couple of minutes. I did:

The 20 foot cable on the MC has always been long enough that I have never needed an extension cord. You must have some unusual charging situations to need one...
I don’t see the 14-30 adapter for Gen 1 on the Tesla Shop. Is it discontinued or just out of stock?

Yes.It's discontinued... you can mod the 14-50 as shown above or just order the Gen-2 14-30.

What circuit box do you have? 100 amps? 200 amps? Maybe time to replace it?I logged in to reply to this thread...
I use a Tesla 14-30 adapter as my primary charging option at home each night for my Model S. My home is newer and had a 14-30 outlet existing in the garage. I had an electrician come out to evaluate re-wiring it to 14-50. Unfortunately, the wiring conduit is so tight and has so many turns that it would be very difficult to pull a thicker gauge wire through the conduit. The other option I have is to bury a line from my breaker box, across the front yard and through the garage wall.
I was fortunate enough to find a Tesla 14-30 adapter at a service center and purchase it.
Also, haven't there been problems with mobile connectors failing due to heat issues when using a 14-50 at 40amps every night? 24 amps nightly has not caused any issues for me and I've never had less than desired charge in the car when I'm ready to go.
Definitely would like to see Tesla offer more adapters in their store.
