Bottom feeding main disconnect against nec rules?

If the terminals are labeled line and load and the load terminals are on the bottom it is not permitted. Many MCCB are available in reverse feed configuration where it can be fed from the bottom and there is no line or load label. I have not seen a disconnect switch that is not labeled line/load.
