Short version of a long story:
We're upgrading the wiring in our barn and upgrading the service from 20 amps to 100. For whatever reason I had it my head that I could run our 1/0 out of the conduit from the barn to our service at the house, through the walls and right to the box, not understanding this was not really a good idea code wise (made sense to me as it was going to be an electrical chase and covered). An electrical contractor buddy was looking at it for me and advised I needed to have it in conduit from box to box.
Running conduit in the house side of the project wasn't really a good option for us for many reasons, the least of which it would have had to been installed outside the walls and ceiling of our basement, which is semi-finished at this point.
Soooooooo, I was looking for an option that would allow me to install 1/0 in the electrical chase and floor joists, up to the 200 amp panel, without being in conduit.
At this point I think I will install an outdoor rated junction box outside the house where I will terminate the conduit and then bring the 1/0 SER 4-Wire from the house panel to the junction box.
This should be a lot easier then running conduit from box to box and make our local electrical inspector happy at the same time. (win/win? or something like that

).
