I thought stranded couldn't be used under screws but I looked a while and
didn't find a restriction. It is definitely can be a problem. I break the
wire into 2 sets of strands and twist them tightly - works good except
behind device grounding screws. Can always pigtail to solid. Poke in
connections tightened by screw work good. I also thought stranded
couldn't be used with back-stab connections but in 1991 it could.

If you look at commercial installations youy will seldom see anything
but stranded THHN. It works just fine on screw terminals and wirenuts.
They are both listed for stranded wire. Maybe homeowner/electricians
are just not up to the task ;-)

Seroiusly, if you twist the wire tightly it will be fine. Some old
timers say twist it backward from the way it is made. That does seem
to work.

Yea, I havn't had problems with tightly twisted stranded on hot and
neutral. I'm not real happy with the ground because the screws don't have
adjacent barriers to prevent the wire from spreading/coming out like the
hot and neutral do. Backwards is an interesting idea.
You have to be more careful using wirenuts on stranded but made right they
are reliable.

There are always crimp terminals, if done right.
