Ok, from PSE.. They are awaiting a proceed to start a 12 day clock to shut down Sleater Kinney for a few hours. The 12 day is a notification period for the businesses affected by the shut down. I assume we will get one of those notifications since we own a good portion of the center.
The conduit is already in from the SK vault to the Tesla vault, and the lines are pulled from the Tesla Vault to the Tesla Cabinets. When shut down happens, Tesla's contractor will need to pull wires (a lot of them, 1200A, 480v) from the SK vault into the Tesla Vault. Potelco will then connect the pulled wires from vault to vault as well as connect the wires from vault to cabinet as they place the new transformer on top of the vault. Then, they energize and make sure the transformer is good to go, and leave. From there, it's all on Tesla's contractor to power up their cabinets and do the rest of their internal testing and connections.
