I'm not an electrical engineer, but I am pretty sure that every cable that moves should be made from stranded wires. Stranded wires last longer when bent repeatedly. Solid wires are used for fixed installation (eg. inside walls). Any cable with solid conductors must be mounted in such a way that it does not move or bend during use. Electrical resistance is very similar for solid vs stranded conductors.
