I have a Tesla Wall connector (set to 72 amps) that I was using to charge a Model X P90D. The charge current was set to 72A. However after a short while (maybe a few minutes of charging), I got the "Charge speed reduced" message that you can see in the attached picture. The car is saying that it has detected an extension cord or faulty wiring. Has anyone else run into this issue ? The wall connector was installed by a licensed electrician. Thanks!
