I typically individually fuse each component on the rail.. just trying to figure out what the best scenario for a split-top/bottom install would be. I'll definitely put a fuse between the rail and DC cable (that runs to the top) in my bottom-box. Would you also fuse each breakout at the top? Trying to minimize the chance of climbs to replace a fuse, but want to make sure everything is properly protected as well.
