Separating distribution wires from single conduit entering subpanel

Merry Christmas
There is no fill requirements that apply to a protective sleeve.

Ampacity adjustments still apply if conductors are "bundled" for more than 24 inches though.

There been some changes over the years on the rules when bringing a common sleeve like that into a panelboard like that, we need more detail to know whether it complies with rules or not, as well as needing to know which NEC edition applied at time of install.
I wish I knew when it was done. I read the part about ampacity adjustments too. Thanks
 
312.5C and 110.12. then 310.15 c maybe
We don't know if 312.5(C) is a problem with out seeing behind the wallboard

110.12 is problematic in the fact that the style manual says "workmanlike" is likely unenforceable.

Regardless, modern code compliance is not the issue here. There was no article 312 when the unit was built, The closest would be 373 (I think).

I would be inclined to replace the breakers with Eaton/CH style and sleep well. Maybe GFCI those circuits that need protected and aren't.

If only I could see behind that wall. I could get a small borescope?!?!?
 
If those Challenger breakers are "BR" type, then they can go in the panel. It's not the brand of breakers, it's the type that matters. Eaton bought out the Challenger line and the BR breakers interchange. I will say that some of the older Challenger panels did not use the BR breakers, so look at the breakers and see if they have "BR" on them.

Be careful just saying Eaton/CH. Eaton has a "CH" type panel and a "BR" panel. I know your CH means Cutler Hammer, but not everyone would understand that. The CH and BR breakers are not interchangeable.

In Florida insurance guys see the breakers and require replacement. If it’s a full panel the whole thing has to be replaced. It’s a FL thing.
