Load calculation with panel change

[Fred B]

Question, when just changing an existing subpanel, do you do a full load calculation and resize or simply replace like for like? Say existing sub is not a full boat.

Any obligation in code to recalculate?

I don't see any requirement in the code to redo the calculations, however the permitting authority might have some such requirement.
