UMC1 was also fully potted, whereas UMC2 seems to be an open design complete with vent holes. I wouldn't expect it to have any water resistance. I'd worry more about UMC2 having problems in real life, than the occasional person with a bad or worn socket. I spot check the temp on the plugs whenever I use them anyway.

I am not sure what you mean about getting the service center to schedule a 72A upgrade. If you mean as to install a wall charger on a 90 amp breaker, which would provide 72A of charge, you would have to talk to an electrician. Only thing the service center may do is find one in your area to come to your house. I just use Angies List or HomeAdvisor to find electricians in my area and get some quotes. The size of the breaker will depend on the size of your breaker panel, house main wiring, and how much you are willing to spend.
You need the on-board charger to have 72A capability. Ravens are not shipping with this, if it is, it's software disabled.Tesla has offered in the past to soft-enable and/or switch out the onboard hardware for a fee. I've seen $1700-$2500 quoted. The question is, will they allow you to do this for your raven. Certainly this was advertised for 2016-2019 cars pre-raven.

How does this charge on a supercharger at full rate if it needs an upgrade to do more than 72A?

Hmm.. did not know that. Also did not know you needed an upgrade to the onboard charger to support full wall charge speeds at max. I only put in a 60A breaker so I am content with that. That is more than enough to top off my pack each day.

I have had my Service Center guy on this more than month before our Raven delivery. He told me last week that there was no longer a 72Amp charger upgrade path. So sad.....That would be the ONLY thing I miss about my S100D....but I do miss it already. My S85D had 80Amp home charging and that being almost twice as fast as our Raven was so convenient for quick charges at home.
I don't see the need for > 48A 99.9% of the time. Maybe if you're a rural realtor driving 400 miles/day with clients and need to do a major top-up over lunch? Not trying to be disparaging, but what is the actual need for > 48A? 48 is enough to charge any Tesla in < 10 hours (overnight) at home. In my 3+ years of electric driving I've yet to see a single L2 charger in the wild capable of more than 48A charge power, so no use there. Where did you guys use 72A, and to what benefit? I understand that there's theoretically a scenario where you roll in somewhere with a low charge and have to charge up and get back on the road, but even at 72A that's a PITA--more than 4 hours for 3/4 of a charge vs a bit over 6 at 48A. Both scenarios suck if that's the need.
I take back the comment about never having seen an L2 that can do > 48A. Some Tesla Destination Chargers can, but they're generally paired or in quad setups, and if even one other vehicle is charging, you're limited to 40A even in those scenarios.
I'm legitimately curious, as 48A seems like the clear call for Tesla to have made.

Same here, 300 on 100% for performance ludicrous. In real world driving, though, I'm actually seeing really good efficiency. Yesterday I drove a 60 mile round trip and pulled off 309Wh/mi

That is an odd chart. My S85D 80Amp would get 58mph charging and my Raven S 48Amp gets ~34mph. Whomever created that chart lost count about 11.5kW charging.
so Tesla wall connector can be set to 80A and it charges fast?
I thought on-board AC charger is maxed to 11.5KW, so installed 60A breaker. If it can take more I will change to 100A breaker.
Please express your displeasure at Tesla. I know I will.
I don't believe there is a technical limitation. Going to investigate in my own car shortly if swapping chargers is viable.

That's the issue @srachamallu Up until very recently you could pre-order or have a Service Center upgrade you onboard charger (for a price $$$) to a maximum of 72Amps or 17.3Kw
