Insert bare stranded wire, tighten screw.
I really dislike these types of connections. In my experience the set screw needs to be retightened often, the copper gets all oxidized, the screws can loosen up and the wires fall out. Yesterda...

I have noticed that many of these terminations are made of tin plated aluminum. Now brew up a thermal expansion nightmare of aluminum, copper wire and a steel set screw and "Kimosabe, I see big problem".
UNBRAKO sells serrated point set screws. When I encounter a nightmare, I will exchange the standard flat or dish bottom set screw for an unbrako, tin the wires, file a flat spot on top, grab and small Crescent wrench to support the fragile terminal, then put the screws to the set screw. And I sure agree, a second or even a third re-tightening may be necessary.
I grumble about this......"@#$%^&! should outlaw aluminum copper interfaces!"
