regular old red scotchlock/ideal wirenut/wingnut
twist the stranded
line it up with the solid,
clip the ends off evenly,
then poke em into and then twist the wirenut.

I have to make some connections inside an electrical box between #10 solid
and stranded #12.
I tried wirenuts, but it doesn't seem particularly secure.
I have only used crimp connectors on standed; can they be used on solid?
If not, then what? Thanks.
