A typical bus bar has this design:
and connecting a solid wire to it is more or less easy. But how do I connect a stranded wire? I expect the following to happen: when I drive the screw in, the screw splits the strands and so I end up with the screw driven in and the strands all around the screw instead of being pressed to the bus bar. I'd like to avoid this and get a good connection capable of carrying many amperes of current.
How do I connect a stranded wire to a bus bar?
