But then why not run 6 gauge in case they are further upped to 50A support? As far as I can tell, your installers had zero indication that the PWs, which Tesla specs as needing 30A breakers and 10 gauge wiring, would ever get a software update that would allow for higher throughput.Yep, for 99%, most would not care, let alone know there are changes. I guess many just are happy to have them. Most places will match a price reduction within 30 days. I would just expect my installers to know how to wire a setup to be future proof. All they had to do is run 8 gauge and case closed.
