The other day I was charging my Model X with the UMC and NEMA 14-50 outlet that I installed at home. I think I was charging at 40 amps. We noticed a buzzing sound coming from the electrical panel. I could also feel heat coming off the closed panel. I unplugged the charger and the buzzing stopped. Since that time, I've only been charging while I'm awake so that I can monitor the panel. I also dropped my charging rate to 35 amps. I haven't heard buzzing, but I still feel some heat. I have a 50 amp breaker for the outlet and my panel is full. I have the electrician who installed the outlet coming back today. Any ideas or suggestions? Is my panel maxed out? Have you experienced the same conditions while charging?
