    Can you always use a higher gauge wire? Does over gauging wires affect the fuse choice?

    If a higher gauge wire fits in the terminals, is it ok to always go with the highest gauge possible? Let's say the expense is not the concern. For example, let's say I need only an 8 AWG between the charge controller and battery bank, and I decide to use a 4/0 AWG wire. Is that bad? Does...
