IIRC, automotive fuses rating are based on a maximum of 32VDC-36VDC. Voltages above that may cause the fuse to blow (48VDC) the fuse to blow "early".
ktrmrfs is spot on with his statements. What people need to understand that the "variability" of a fuse. A 15A fuse will "carry" 16A of current for hours and not blow. It might even carry 20A for several seconds.
Back to the OP original concern. ATO/ATC sized inline fuses older with either 10AWG or 12AWG are readily available online. Although you can get these fuses up to 40A, If I needed a fuse larger than 30A I think i would use a Maxi-fuse. These typically come with 8AWG wire.
