Pretty sure those are the old pads for the previous chargepoint install or maybe transformer / switching pads for the site in front of where the superchargers are? They were there before the supercharger work broke ground.

That's a big honking transformer, and indeed, upon taking a closer look, it is a 1500 kVA unit, which is about twice what most sites utilize. I wonder if they are short of the 750 kVA units and are installing an oversize unit to get it up and running.

I'm not sure that they can simply upsize a transformer like that. I'm not a utility engineer nor a electrical inspector, but I am a former electrical engineer and do know that there is a relationship between the KVA rating of a transformer and the interrupt rating of the main breaker(s) on the service entrance equipment that has to be in some kind of design agreement and that also takes into account the length and rating of the service drop conductors. Maybe it's fine and maybe I'm wrong - not sure.

Kind of weird if they just left it like that. They must have reason to leave it there.

They were paid to install the SuC. Probably nothing involving the old stuff.
Thanks - I think that is new. They weren't there over the weekend when I checked the site. There was no sign of a meter Sunday.
Had a chance to take a pic today. I’m pretty sure someone has been here and did some work. The 1-4 label is definitely new and corresponds to the 1-2 and 1-3 labels I see on the other transformers nearby. The only difference is there is no lock and yellow lock labels, which means it’s not live yet. But it’s progress!!

Saw 2-3 utility trucks there today. Didn’t get a chance to look for any changes. Maybe on Monday I can swing over.
Excellent - last updated I heard it was waiting for a meter (and power to the transformer). Sounds plausible that's been done, possibly adding that to the other sites awaiting Tesla commissioning (Lynnfield, Foxborough and Provincetown).
Thank you! Curious if you looked at the meter to see if it was live (showing/flashing numbers). Even if it's not, this is one step closer.
