4 Gauge to 0 gauge power

[LoSx 0]

Due to my battery hookup location and the fact that it will be nearly impossible to get a 0 gauge wire on it unless I rewire the alternator and main power line toa new battery block, how bad would it be to run 4 gauge wire to a fuse block and 0 gauge afterwards? According to charts 4 gauge should be able to handle up to 300 Amos if it is a short length.

 

So will battery —> fuse (4 gauge 1 ft long) —> distribution block (0 gauge guessing 13 ft long). Will this work ok?

You'll be okay.
