At a CEU seminar the speaker stated that this terminal when used with two conductors were permitted to be used only to terminate parallel conductors and therefore are only permitted with conductors that are the same size as part of the listing. Has anyone ever heard of those two requirements when landing two conductors?

I've seen that requirement more than once where you can have two wires on the terminal as long as they're the same size and both are stranded or both are solid. I we'll see if I can find such a terminal. Of course now that I've opened my big mouth about it I won't be able to find one with that kind of restriction.

Here's an example where it explicitly states "No mixing wire gauges":

This doesn't necessarily mean that you could only use this for conductors in parallel, just that you could only use it for two conductors of the same size.

I have asked Square D about the "snowman" lugs they use on the 400A disconnects, and whether it was permitted to mix sizes in the two-wire range within the same barrel, and the answer was that it was permitted. Just not allowed to mix aluminum and copper in the same barrel (which I expect), even though the lug is rated for use with wire of either metal.

Well, welcome to the 21st century.
Noticing having two(2) 1/0 conductors (together) under same lug (hole). I remember @ one time, must use lug having (tear-drop type hole) being the only mechanical lug acceptable for "more than one conductor" in same lug hole.

Not visible from the photo but that is a tear drop shaped hole in the terminal.
 
infinity.. Open link in post #6, the third window in the link. Click on lug (expand) w/two 1/0 conductors. in same hole.
 
This kinda thing is why the code should contain 'construction specifications' for something as simple as a lug and not require them to be listed.
There are ongoing efforts to make every nut, bolt, screw and ziptie you all use to be 'listed'.
