New Tesla owner. I live in a mixed-use (commercial and residential) condo building, so the power coming in is 3 phase. Therefore, I get 208V rather than 240V at my NEMA 14-50. Using the Android app, I see that the charging current is 30A, rather than 40A (it shows 30/40 A. with a charging rate of 19 mi/hr. Is this the normal charging rate for a 208V line?
