L14-30 Garage Outlet

I did find that it was connected to a 50A breaker. I have an electrician scheduled to replace the LI-30 with a NEMA 14-50.

Other than checking the wire in various capacities, assuming that all checks out as acceptable, it should be as simple as installing the NEMA 14-50, connecting the mobile charger and charging at 32A moving forward?

Yes. Presumably you meant Mobile Connector, not Wall Connector, right? The mobile unit that has interchangeable pigtails.

While it is connected to a 50A breaker, I am still skeptical that it has 8 or 6 gauge wire. That L14-30 30A receptacle could have use 10 gauge (and improperly connected to a 50A breaker). You’ll have to check the wire itself.
