I have built a few different adapters to convert to my NEMA 6-50 connector for my mobile adapter but haven't tried any of them yet. One outlet that is also 50 amps is the 10-50 outlet which was historically used for welders and such but does not have earth ground like 14-50 or 6-50 plugs do.
My question is has anyone actually tried using a 10-50 outlet to charge their Model S? I am assuming it will work and charge at 40A but wanted to make sure it would actually work as I plan to drive to my cabin about 150 miles away which has a 10-50 outlet in the garage. I can't really see how it could *not* work as there should be no way for the built in charger to actually detect that I am connected to neutral rather than ground but just checking.
I will eventually rewire this otulet to 6-50 or 14-50 so I have earth ground as well as neutral but that is a later project.
And just for clarity, my adapter connects the two line phases to the two line phases of the 6-50 connector and ties the neutral pole to the 6-50 ground wire.
I am just looking for actual experience to verify that it will work. I know I can just try it and am not looking for obvious common sense advice, just experience with this specific outlet configuration.
