This is a question I have been meaning to ask. Why in an automobile the stranded wire has so many strands? Can you replace it with standard stranded electrical wire? Whats the difference?

| DC does complete saturation of wire where AC doesnt,,,,so i guess with more smaller strands, better preformance... its easier to tuck, bend etc and work with. my 2 cents

| Smaller stranded wire is more flexible. making it better suited for service in a vibrating environment. Smaller stranded wire can carry more current due to the larger surface area of the conductor because of skin effect.

| I always use MTW (Machine Tool Wire) when doing auto work. Oil resistant, 105C degree rating and very flexible.

| Power = Volts x Amps. For a 12 volt system you need 9 times more amps than a 110 volt system to deliver the same power. Nine times the amps means 9 times the area of the wire. Stranded wire is more flexible than single strand wire and less likely to break when the assemble line is speeded up. quote:
