    Schmelted UMC/NEMA 14-50

    Just had my UMC + NEMA 14-50 replaced today. Schmelted the old one. It still worked, but clearly faulty.

    Not really sure - I have the newer style adapter and this should not happen with it. Only reason I discovered it was during a conversion with a Tesla rep that they were replacing all the original adapters with newer ones. We inspected my NEMA 14-50 and I had the newer version already (the old version were earlier than my vin, so most people have the new ones already, must be earlier than 5k vins)).

    Anywho, upon looking inside it we found it melted both the adapter and UMC. He was very surprised to see that I had the new one and yet this still melted. He did mention something like when you click the adapter onto the UMC that it needs to be fully clicked in - no gaps. He mentioned something like the metal clip in the original was flimsy and sometimes this wouldn't snap on fully and if that happens and there is a gap between the adapter and UMC it causes it to melt like that. This should be fixed with the new adapters but clearly not as mine was already melted and he's definitely never seen it happen with the new ones until mine...

    When I went to get my tires rotated, I got replacement adapters for 14-50 and J1772.

    My understanding/recollection is that the 14-50 replacement was to deal with the melting issue while the J1772 was just that some cars and/or stations had fitting issues.

    How do you tell if you have the old or new adapter?

    The J1772 versions have different TPNs (part numbers).

    Functional differences reported by Tesla:
    1. Better fit for the broad array of J1772 EVSEs in the marketplace.


    Observed differences:
    1. P/N change from 1005617-00-A to 1005617-00-B.
    2. Newer one is shinier.
    3. Color change from gray to bluish gray.
    4. Triangle-with-exclamation icon next to the "CE" logic changed from yellow to white, and no longer has an inset black triangle.
    As for the 14-50, my new one has...
    1014324-00-B
    ... on it. I presume the original ends with "A". But that's just a guess as I don't have my original one.

    As for the 14-50, BRB...
    Thanks. I'll search around in the threads. Took delivery in December so I'm guessing I may have the earlier version? Maybe I'll just take them into the service center and ask them.

    I had one of the newer 14-50 adapters too when mine was replaced. It just appears that over time, some UMC's are not making full contact and it's generating heat.
