Does anyone have one of the discontinued NEMA 14-30 adapters for sale?
Tesla Universal Adapters - Available in North America Only
Pretty sure he's asking for the discontinued 14-30 adapter for the Model S Mobile Connector... not the Roadster adapters. I wouldn't mind one of the 14-30 adapters myself, actually.
Yes, you're right. I'm looking for the discontinued one for Model S. Sorry I wasn't clearer initially. Please let me know if anyone has one they're willing to part with.
Looks to me like a simple build it yourself project. Buy a 14-30 plug at home depot. Buy a 3 foot piece of wire, 6-3 w/ ground. Buy a 14-50 outlet. The plugs are marked, usually, red, white, black, and ground, on each prong. Same with the outlets. Then plug into 14-30 outlet, and plug your UMC into the 14-50 end. Should cost less than $50, as I remember when I made mine. (You can pay extra for fancy plugs and outlets. Shop around.)
The only thing about this is if the Tesla one told the car to drop to 24 amps of charge or less. But I don't think they did. You have to do that step yourself when you use an adapter. Which is probably why Tesla doesn't make them.
I never have used mine, but I never know.
You can literally just cut the neutral prong off the 14-50 adapter, then it will work in 3 outlet types; 14-30, 14-50 and 14-60. The neutral is not used in the UMC, and it's just a dummy pin. Just be sure to set your max current to 24A when using it on a 14-30 or you will trip the breaker.
I grabbed the pin with vise grip pliers and ripped it out, then just filled the hole with sealant. I use it all the time and it works perfectly.
I was able to buy a 14-30 adapter two weeks ago from a SC in California. I think it was the Palo Alto SC. i don't know if they have any more in stock.
I bought a CAMCO adapter for 50 bucks.
So glad I found this. Thank you. I was about to waste 50+ bucks on an adapter. Glad I don't have to now.
I noticed the adapters on evseadapters.com don't have the neutral pin either, which supports your decision. Thanks again.
Good info - thanks.
What I am reading is that the Tesla supplied 14-30 adapter has a limiting resistor which only allows 24amps to be pulled. This is a big deal. Otherwise I am depending on me to ALWAYS remember to manually set the charging limit to 24amps or risk melting an adapter.
I am looking to purchase an original 14-30 Tesla adapter.
You wont melt the adapter if you forget, you'll only trip the breaker. Keep in mind the Model S remembers your amp setting by location, so you only have to remember to set it once.
Assuming your breaker works properly. There are still a lot of the old FPE Stab-Lok panels/breakers out there that are known to not always work as they are supposed to.
