Hello everyone. Panel is located in crawlspace in a floodzone area. In order to get flood insurance, panel needs to be relocated upstairs. A few questions about project:

1) I am thinking removing existing romex circuits from existing panel and land them in a pull box close by. Run pvc from pull box to new circuit panel upstairs and run new circuit extentions in thhn. Would running a common grounding conductor within the pvc pipe be ok in this scenario to accommodate all new circuits to new circuit panel? If so, largest circuit is fused at 40a so I am thinking one #8awg grounding conductor would be ok?

2) I dont plan to do this since the existing panel is rusted and rotted out, but in general, would removing the guts of the existing panel and using it as a splice/pull box be ok?

3) Would running all existing romex circuits into pull box bunching them together with a couple of seu connectors as opposed to using a bunch of romex connectors be ok?
 
1- Yes a single EGC sized according to the largest ampacity circuit is compliant.

2-Yes.

3- Absolutely not. You need to use connectors listed for the size and number if cables installed in them. LArge SE connectors are not listed that way.

If you're running one conduit you will need to increase your conductor size due to have more than 3 CCC's in the raceway.

Yes, but it must be run in a raceway, and as Dennis stated that will require a substantial ampacity adjustment for number of current carrying conductors in a raceway.
Either using multiple raceways or using much larger wire will likely cost more than the cost of UF without raceway for the same purpose.

Yes it is but has to be put in conduit.

I think Dennis was just pointing out the fact that if he ran UF he wouldn't have the issue of derating or wet location.

When I read Dennis's post, I didn't get that he was suggesting using UF INSTEAD of the THHN in conduit. I read it as use UF in the conduit. So my apologies. However, we don't know if the plan was to run the wire/raceway exposed on the outside of the building or inside a wall. If exposed, UF won't work since it has to be protected.
