As an extra precaution, if possible, when using wire nuts to connect stranded wires, and especially stranded wire to solid copper, it is best to solder the wires after twisting together, and then install the wire nuts and tape.
Wire nuts have a tendency to cut thru stranded wires and lose conductivity resulting in wire overheating, but usually don't cut thru the solder.
