Just what the heck am I supposed to do with 100A Sub panels? #3 CU THHN in pipe?
That's what we typically do. MLO sub-panel unless the sub is in a separate building.
I don't follow the other concerns, questions that lead to the 1/0 AL. We don't use AL for sub panels unless we are going underground.
