30A 14-50 Adapter

[ebradway]

I am currently borrowing a loaner Model S while my car is in for service, and noticed the Gen 2 Nema 14-50 adapter that came with this car states it’s only rated for 30A versus mine at 32A. The car does show it can charge up to 32A even with this 30A adapter connected. Has anyone else noticed this? Is there anyway to tell which is newer?

Yeah, that's been known for years. Here is a thread on it from 2020, but it was talked about some before that, but this was the easiest thread to find.

NEMA 6-50 and 14-50 adapters are labeled 30A

I recently bought a NEMA Adapter Bundle from Tesla. All the adapters look good except for the NEMA 6-50 and 14-50 ones. They are both labeled as rated for 30A continuous on the adapter. The Gen 2 Mobile Connector is able to output 32A max, so shouldn't these two connectors be rated for 32A...

They will all operate fine at 32A and are intended to. No one is really sure why they had to mark them as 30A. It may have something to do with tolerances for official testing or something.
