    Default What gauge battery wire?

    I purchased the BlueSea add a battery system and I'm going to install it next weekend. The boat is 2007 Moomba LSV with 325 stock engine. I'm trying to figure out how many charging amps I get from the Alternator so I know whether to purchase #2 wire or #4 AWG wire and corresponding fuse. This wire will be used between switch and the auto charging relay to the batteries.

    Charging Amps / Minimum wire size* / Fuse rating
    60 / #6 / 80 Amps
    80 / #4 / 110 Amps
    100 / #2 / 150 Amps
    120 / #1 / 175 Amp

    thank you
