2018 75D home charging circuit breaker

I would check the wire and see what gauge it is. Is the outlet you installed capable of high draw? It may have worked in the beginning but 3 years of use could have worn something down.

I looked at your photos and that outlet is designed for 50 amps so we should be good on that. Next check the wire gauge. If the size is right, it has to be the breaker (assuming the tesla charger is not bad).

I'm leaning towards a fault in the installation before we blame the Tesla charger. It's hard to pinpoint without all the details

Only way to find out is try a different charger or known good charger. See if another Tesla owner can bring their MC by.

Also max charge on MC is 32A. So the behavior of dropping from the 48A you set to 32A when plugging into the MC is correct.

I would lean more towards faulty install except it has worked without flaw for three years then the 1st time I use gen 2 charge and new Tesla the mc fails...

Another test is, do you have any friends with Teslas where you could test the new Gen2 UMC in their car? It could be the combination. Or test their UMC in your car. It's one or the other. (Well, it could be both, but good grief...) The socket has been used for years, as you say. Be very strange for it not to take a lower load.

it was a bad emc. took an hour to convince service dept to give us new one, but it is working fine now!

I appreciate everyone's feedback tips and suggestions...glad it was just emc, but the service guy told my wife they have had many problems with Gen2 cords...
