One good test that I saw somewhere that I do on new outlets I am charging on, is leave the car charging for ~30 minutes and then quickly unplug the charger from the wall. Touch the prongs to your hands. If they are very warm or hot, you are likely over-drawing that outlet and need to ramp down your amperage draw (or better yet, find a new outlet).
This article focuses on outlets but the wiring is just as (or more) important and outlets can very easily be installed with under-code wiring.
