My UMC gets incredibly hot when charging at 30-40 amps. Mainly the cable between the wall Plug and the UMC. It gets piping hot and from what I am hearing that is considered normal. Service center checked it and says that is normal. The Wiring Cable going to the 14/50 outlet only warms up very little and is AWG 6. Being an Electrical Engineer by trade I can't belive they get away with this and allow them to become so hot. In my days we would not have designed anything like this and would use a heavier gauge that dissipates the heat bettter. In any case, I had a house fire before which (what a coincidence) was caused by a Battery Charger (Dewalt Power Drill), I don't feel very good at going to bed and leave the car charging knowing the Temperatures in the equipment raise like this. Being a fire victim once which happened during lunchtime I certainly don't want that to happen at night while I am sleeping. If I charge overnight I usually dial down to 15 amps. Does the Hardwired Wall connector become this hot as well or is this just a UMC issue ?
