Feeder to sub panel

[Danstorino]

I am going to put a 60 amp sub panel in my new pole barn, the existing main panel is recessed in my attached garage, i have to come out of the side of the panel to penetrate the exterior vinyl sided wall. So due to depth restrictions, I cannot use conduit. Can I use indoor Romeo or use outdoor type since I am penetrating wall and coming into the back of a outdoor junction box, 6-3 Romex is rated for 55 amps, is this acceptable since the piece of Romex is under 6', before splicing onto new thwn going to new pole barn.

I don't know what outdoor type Romex is. I don't recall there is such a thing.

the conductors have to have an ampacity exceeding the calculated load. What is the calculated load?

I don't understand the 6' question. Are you asking can you run a short piece of Romex outside? I think the answer is you can't run Romex outside at all.

If you are asking if you can use romex instead of UF from the panel to an exterior mounted junction box some will say "no" because romex is not listed for exterior use. Even if it terminates in an exterior NEMA 3R box.
Not sure what the six foot has to do with ampacity unless you are thinking de-rate. And even then number of conductors applies not the length of them.

If the NM cable is in a dry location then it can be used to transition to a wet location conductor on the outside of the structure.

In the scenario the OP is talking about , It's that questionable area between the wall penetration and the back of the outdoor j box that always brings on the debates.
Even if it's caulked around.
