Starting to do a little wiring. I know that the wire size needs to be right for the amps and length. I would like to buy multiple rolls, colors of wire. My question is if I get 10ga. wire will it handle most of the stuff I need to run? Can a wire be too big for the amps? I just didn't want to buy a bunch of rolls and colors in a bunch of different sizes, if I can buy 6 or so in the same gauge.
