This picture is very interesting. The large gray cabinets in the rear are the Distribution Center (a really big circuit breaker cabinet). The squat, grey box to the left, and behind the white Supercharger Cabinets looks like a transformer. This is the first time that I have seen a transformer inside the equipment enclosure. In the U.S., the utility transformer is always outside the Tesla equipment enclosure. Because Canada uses a 600/346 Volt, 3-Phase standard and the Supercharger Cabinets expect a 480/277 Volt, 3-Phase connection, is this transformer in place to step down the Voltage for the Supercharger Cabinets and in addition to the utility transformer? Before the equipment enclosure is enclosed, it would be really interesting if someone could take some pictures of any labels, etc on that transformer to further understand its purpose.
