The Ideal website for the Buchanan splice has a link to the UL listing for the
product. It does not list it for use with anything other than standard stranded
conductors.
If it is not part of the listing, it is not approved for that use, regardless
of historical or anecdotal use.
That is what the NEC says, and what the UL listing says and the UL
specification for their listing says.

Jeremy,
Without digging into the specs on the Ideal connectors, I doubt that they
will work with fine-stranded wire.
The problem with these types of connectors is that the set screw that you
turn to tighten the connection is in direct contact with the wire strands.
As you tighten it, it rubs the strands in a circular motion, which will
stretch, flatten, and tear the strands. It would work fine if you use
ferrules, but not without them.
Terminals that are rated for direct use with fine-stranded wire would have
a clamping-type terminal, where the screw used to tighten the connection
pushes down on a solid piece of metal which then clamps the wire. Even in
this case, it may still not be approved for fine-stranded wire depending on
its design.
The Buchanan splices should be fine. They are basically the same as a
ferrule, except that they are crimped with a crimping tool instead of the
pressure from tightening a screw in a bus bar. The crimping tool is not in
direct contact with the wire strands, so there is no tearing or other
damage to the wire. However, the spec sheet does not specify the acceptable
wire types, and I can’t seem to find anything with a Google search. It
might be worth contacting Buchanan/Ideal to see if they have better info.

I'm looking to bring 8 Enphase 240V circuits in multiple conduits into an
enclosure inside the attic where I can transition to Romex. I'd rather use
some kind of rail mounted terminals in an enclosure or something rather
than making splices in a generic j-box. I'm not looking to combine circuits
- just transition from THWN to Romex and keep things neat an organized.
Any suggestions?
