Conductors entering another building

Hey all!
I'm on a project where a building (#1) has a feeder that feeds another building (#2). At the point where the feeder enters building #2 is a pull box; from the pull box the feeder keeps traveling further inside building #2 to a switchboard that serves the building. We have to relocate the pull box / the point of entry where the feeder enters building #2. However, I believe that instead of a new pull box located at the new point of entry for building #2, it should actually be an unfused disconnect switch, based on section 225.31 in the 2008 NEC. This would comply with the requirement for disconnecting all the ungrounded conductors entering a building. Would this be correct? Looking for feedback. This building was built maybe in the 70's or 80's, so i'm not sure if the code required a switch back then.

Thanks!

Not sure what the code was back then but if you move anything then, IMO, you need to upgrade it. I agree a disconnect on the outside is all you need and it does not need to be a fused disconnect.

Adding on to my question in post #1... what if this feeder goes through a basement that connects building #1 and building #2? The feeder never goes outside. Is that disconnect switch for building #2 needed? They are still considered separate buildings, with different addresses.

EDIT: I went through some previous posts on this topic... but not sure for this particular case.

EDIT #2: The buildings are not physically connected above ground. Below ground however, there is a passageway that goes from one building to the other... however, the feeder goes through an underground space (not thru this passageway) that terminates right at the wall of building #2, underground. The construction is a little strange. The feeder never goes outside however. and like i mentioned above, each building has its own address.

This doesn't sound like it meets the definition of two separate structures.
