Spamming the TMC brain trust, since I have no clue who else to spam. Some Mercedes EQ vehicles now come with a free Wallbox EVSE. Unfortunately, it doesn't have normal screw/hex/torx lugs for the conductors (L1, L2, GND). Instead, it has what you see in the images below (potato chip for scale). Does anyone recognize how you're supposed to get your copper conductor properly inserted?
No joke, the Wallbox installation manual and the MB-USA installation guide just tell you to get a qualified electrician to do the install. Contacting Wallbox support just gets someone who sends a PDF for the previous-gen Wallbox instructions that has normal lug screws (philips).
My neighbor is a former electrician, and he's said he's never seen this. There are no instructions on how to use these lugs. There's also no other min-busbar or other bracket in the box. No extra lug hardware or anything in the package.
Our hypothesis is that Mercedes actually wants you to go through specific installers who actually have the hardware necessary to affix conductors to these lugs. Kind of like getting a lock for free, but no key. Or maybe there are some bullet termination ends we're supposed to crimp on and jam in there? Very weird.
