run nm through short length of conduit?
Hello, I will be running 6/3 wG through my unfinished basement to the opposite end of the house for a hot tub disconnect subpanel. My question is how best to get from inside the basement to the subpanel outside? I was thinking a short length of pvc conduit through the rimboard into an LB and up approximately 2' to the panel. But I have two reservations with this: 1) I'm not sure I can run the nm through conduit (even short lengths) and 2) I'm not sure the 6/3 can turn 90deg up in the LB.
What's the best way to handle this? And thanks!

Yes, the subpanel is outside. But it is (or will be) higher than the rim joist, so I guess I need to either enter the wall above (a bathroom) and then into the subpanel, or use a sweep and short length of conduit. I just wasn't sure I could put nm in conduit.

the inspectors here permit a vertical conduit to an outside box to contain NM for mechanical protection.....either up to the attic or down under the house
we do not have the build up of water in our vertical pipes as some seem to.
i called and they use ART. 334.15 (B) "Protection from Physical Damage"

NM is permitted to be sleeved against physical damage. The code does not permit NM to be used outside even if in conduit.

Okay, so then my only choice is to use a junction box inside and use thhn/thwn to the subpanel or somehow get the NM up into the wall and then into the back of the subpanel.
