Sigh. Nice of you to use the word "actually" and then have this a little bit wrong.Actually, 240V is standard single phase power running into any residence/building.
I think you meant to say "into any residential building". Residential buildings, like houses do get those split phase 120/240V supplies. Commercial buildings generally don't. It's not correct to say that 240V is into any residence or building, which is what your slash mark is saying.
Right, and that is what most commercial industrial buildings have.To get 208V, you have to have three phase running into the building.
Well, OK. That is extremely unusual for a building to have BOTH the split phase and the 3 phase supplies, so they can have both of the 240V and 208V circuits at the same premises. Buildings are almost always only one or the other. I was definitely not expecting that would be the case.The SC does have a row of HPWCs that are connected to 240. The 208V outlets are all in the shop, which is where the previous dealer probably had various equipment plugged in.
Whoa--interesting. So your and his cable and your and his car, and they all showed those errors when using the one outlet at your house. That seems to indicate something. The electrician checked the connection of the outlet, but I do wonder if there is a problem with the supply at your house or neighborhood.We tried his UMC as well. The current tally is that I've tried four different UMCs at my house and another UMC at another house. All produce the same issue.
There isn't a gen 3 UMC yet, but I get that, replacing the gen 1 from your 2016 car with a gen 2.The first thing the SC did was replace my gen 1 UMC with a gen 3 UMC. Considering the number of cables that I've tried, I don't think it's the cable.
