    Can't really answer your question...

    Check out the onboard fuse rating of all your amps, then add them together to give a total...
    EG; Amp 1 = 2x20amp, (40amp total) Amp 2 = 3x30amp, (90amp total) Add them together, 40amp + 90amp = 130amp in total....

    The overall max draw, (130amp), in conjunction with cable length denotes what power cable you should use... The cable used denotes what fuse to use...

    Assuming 4.5m cable length;

    8awg = 30amp fuse
    4awg = 80amp fuse
    0awg = 200amp fuse
    if it sounds right to you, then its right.

    not sure on what size the cable is but has been fine for about 2 years its not big or small so would 8awg sound about right but the one that melted was yellow so that would be 20 amp should it not have blown 1st

    Yes & No lol...

    A 20amp fuse will not blow as soon as 20amps is exceeded, it will support a steady draw of a fair bit more... I would guess a 20amp fuse would blow at around double its capacity, (40amps), assuming there is a dead short in the line....

    As a fuse offers a point of high resistance it will tend to melt rather than blow if a continuous draw exceeds its capacity....
    if it sounds right to you, then its right.
