I've been charging my MS in my garage with the UMC for at least a year now on a 30-amp 14-30 socket at 24 amps without incident. Today I plug in and the car started charging fine and I went inside. About 10 minutes later, I get a mobile alert that charging has been interrupted. There's a sub-panel breaker box in my garage with a 30-amp breaker for 14-30 socket, and that runs to my main breaker box with another 30-amp breaker for the garage sub-panel. The main breaker was tripped. I reset it, and then went to the car and the charging limit was set at 24 amps as I had last set it. I don't know why the breaker tripped. So I dialed the car down to 20 amps for a little extra headroom and started up charging again. The car starts to charge at 20 amps. Now I go back to check my power monitor, and see that the car was charging at 40 [email protected] volts (10kW) for 10 minutes! (see graph): So my questions are: 1. Why did the car start to charge at the full 40 amps, when it was clearly set to limit to 24 amps at this location? 2. Why didn't either circuit breaker trip during the first 10 minutes of pulling 40 amps? 3. Do I need to worry about either/both of these circuit breakers not tripping for 10 minutes at 40 amps? 4. Has anyone else seen their car ignore the charging amperage setting and charge at the full 40 amps? thanks.
