    Thoughts?
    That is not a "main" panel, and an excellent display with drawing and photos of why not to refer to it that way.

    Drawing shows "service equipment", which is the 100 amp disconnect, (and which is "the mains panel" if anyone really, really, really has a need to use the term "main panel").

    The drawing then shows an electrical panel, a good way to identify this panel is "Panel A, located in the basement".

    The drawing then shows another electrical panel, a good way to identify this panel is "Panel B, located in the first floor".

    After the above ... I see a lot of "white" wires! Most of which are not "neutral" conductors and need to be identified as (typically) back and red.

    The "service equipment" panel has a 100 amp breaker in it ... on a piece of wood! ... with conductors from the breaker to the 'safety switch' ... the 100 amp breaker "is" the "service disconnect". The neutral/ground terminal is multiple tapped, and is likely not rated for such. That service equipment panel is in dire need of a do-over (i.e., "replacement) by a qualified and licensed electrical contractor as that definitely looks to be modified panel, which is not being used in accordance with its listing and labeling, which is a code violation. Calling that out for replacement covers anything else in that service equipment panel.

    Panel A is excessively rusted and has many issues and is in need of replacement by a qualified and licensed electrical contractor.

    I see three separate white feeder conductors leaving Panel A, but I only see two white feeder conductors entering Panel B - am I just not seeing the third white feeder conductor in Panel B? Wait ... there it is coming up into that large hole in the bottom of Panel B - see comment below:
    - Feeder conductors which run from Panel A to Panel B need to be replaced with proper feeder conductors in a cable or raceway by a qualified and licensed electrical contractor.

    Panel B - see Panel A and feeder conductor comment. Qualified and licensed electrical contractor needs to correct any and all other code and safety conditions which are in Panel B.

    That, to me anyway, is the best way to address that mess.

    A subfeed from one panel to the other is fine, it's how they did it in that place, is what is wrong, the feeders, and that rusty ITE panel needs replacement badly as does the double lugging.

    Just looking around today and spotted this. Did you guys miss that the individual wires between panels run into separate holes in each panel?

    Nothing to see legal here. Move on.........
