NEMA 14-50 adapter no longer included with vehicles

So you pull out your UMC while getting it repaired. UMC's can fail too why are WC's exclusive to failing?
Adding a spare outlet isn't a bad idea, assuming it still meets code and includes GFCI. Sure, why not.
Very good point. Never thought of that, but makes perfect sense. I have been charging at home with my UMC for 5 years. I mainly never saw a reason to spend the extra money on a WC when the UMC could do the same job just fine. Installing a 14-50 was $50 and one hour of work for myself.
120/240V in the USA 110V was likely not around when before you were born.
You can get a replacement UMC from a service center quickly. They will help you out while you order a new one which takes only 2 days max.
If your wall charger fails where are you plugging in your UMC, you yourself said they need to be hardwired and 14-50s are dumb. If my UMC fails on my 14-50 I take it to tesla and get a new one they have in stock the same day and continue about my life.
This is priceless, since you are the guy who ranted about how the UMC is unreliable, failure-prone garbage, so everyone should use a wall connector anyway. Thank you. That was hilarious.

That is good feedback, thanks. I am about to build a new house and I am wondering how much of an issue that might be.
The Internet is full of page after page after page of complaints about AFCI's and I have had friends that have had issues.
To be fair though, I am not sure how I would know the difference between a nuisance trip with AFCI and a real dangerous arcing condition. Can you explain how you troubleshot the one real problem you had?

One case it found was a hanging pendent light fixture. As soon as I put the breaker in, it immediately kept tripping. Removed bulbs and everything. I immediately took the light fixture down and tossed it. The light was "working" fine. But the AFCI was detecting a fault, wasn't worth messing with. I tried another breaker too. I have the AFCI's on circuits that are known be prone to issues, but I was curious and used them any way. Things like a fridges, furnace etc. might false trip. But I never had an issue so I left them. I never had one trip since (3 years now?). I also like them that they retain the reason why they tripped (Load or Fault).
Not everybody can easily add _two_ 240V circuits.
Since I'd be buying a car with only 32A AC charging, my plan was:
- have a 40A socket installed
- buy an extra UMC
- leave that UMC with the 14-50 adapter plugged in permanently
- keep the other UMC in the car.
That way, it'd only be $300 extra, and, whichever EVSE failed, I be able to use the other.
I can appreciate that many people would not use the 14-50 adapter so it saves Tesla money, and allows them effectively to raise the price by not passing on the savings, and push people towards making their primary charging the more expensive wall connector and corded mobile connector.
120V will get you by. That's what I did for the first couple weeks. What's the big deal.
You should always have a UMC. What's your point?
So your argument is, folks should not install Wall Connectors because they can fail and take 2 weeks to replace.
That's a perfectly sound argument.
Yes, for the vast majority of users Wall Connectors are a much safer solution and apparently Tesla agrees with me, not you.

The neutral is NOT used at all. You can cut that pin off and it will work. (now that creates a situation where you can pull more current on a 14-30 than you should - so naturally ). The EVSE Adapters extension cord for instance just plain old omits that wire in the cable.
I should note that the UMC *does* test the neutral in one specific case. That is if you use a 10-30 adapter. That has no ground, and so Tesla treats the neutral as a ground and will test it as such. But this does not impact the answer to your question.
I literally just posted this quote I got back from Tesla Charging support just a few minutes ago:
"It was a short term offering, but we are looking into bringing it back."
You are SOL right now, but maybe some time in the future they will bring it back... :-(

So I am curious:
Does anyone have any data on whether it will continue to be included if you buy an *extra* UMC?
Gen 2 Mobile Connector Bundle
If they remove it from that, I wonder if there is a chance they would make the bundle less expensive? (hahaha)
