60a fuse is 20% higher than the maximum draw to avoid nuisance disconnect. Still plenty of protection if there is a short. A 30 amp DC-DC charger can easily pull 45 amps if the input voltage is sagging. 10 volts in 14 volts out = 40% more amps needed + efficiency losses.
Although #8 would seem to be fine for the input side, #10 for the output. Best to mount the DC-DC charger close to the battery that is charging.
No issues with 270 or 240 amp alternator.
