43 and
46 in the Auburn Supercharger thread have pictures that show what I mean.
Each supercharger site consists of the 3 grey Square D boxes and 3-4 white Tesla boxes (each contains 12 chargers that feeds two charging stations). This is all Tesla owned equipment, and is inside the fence. You can clearly see that in your last Hooksett photo. However, the utility-owned transformer (about 1/2 the height of the tall Square D box and wider) is mounted outside the fence, often on a separate pad.
When I was there, it looked like the bump-out in the curbing would only have enough space for the fenced in area - I couldn't tell where they would put the transformer. But at that time, there was a big hole in the ground, so it was hard to tell, and I didn't think to ask the crew.
There is a large transformer many spaces away (close to the building, behind where the food truck was parked), but I assumed that was for the building itself. Most (all?) supercharges get a dedicated transformer.
I'll snoop around more on Thurs.
