2020 NEC: is there any minimum amp rating requirements for feeder breakers of a residential condo?

[fandi]

Hello All,
The main panel that feeds the entire condo is being replaced with new but the subpanels of the condo units are existing. In 2020 NEC, is there any minimum amp rating requirements for the new feeder breakers at the new main panel of an existing residential condo?
Thank you.

Assuming everything is one building, I don't believe there is any minimum.

The NEC does not care if something is a 'condo'. It does care, for example, if a service or feeder supplies a building that consists only of one dwelling unit.

Wouldn't you be more concerned about the max overcurrent protection for the existing sub-panels and existing feeders supplying the units.
