The above is a Google Earth photo of a nearby Tesla charging station. I was curious about the white boxes to the right, and so went over and took a couple of photos.
Off to the right you can see some large boxes, and outside is a label as shown below.
This box is a circuit breaker, a scaled up version of what we all have in our basements or utility rooms.
In the post below I imagined that I was looking at a generator, and thought it odd. I suspect that our friend Greg whose comment I repeated in the post saw something similar, but I don’t know. I chatted with a representative of Emsco, which supplies these breakers, and referred to it as a “motor,” or something with moving parts. He assured me it has no moving parts.
It is not a generator. End of story, but I appreciate always both skepticism and curiosity.
