I'm installing wire (4/0-4/0-2/0-4) to an outbuilding. Because of the size of the wire, it has to bottom feed from the existing 200A panel, thus, no breaker on the upstream end other than the main breaker in the upstream panel.
Is it legal to connect the new wire to the bus bars before any inspection has been done? Because of the difficulty of bending the wire, I'd like to be able to connect it before finishing the downstream sub-panel. The main breaker would be off when doing all of that work. Once the sub-panel is installed and connected, the sub-panel would be turned off with its main disconnect and the main panel re-energized.
I don't want the inspector to show up and have it connected when it should not be.
