putting a 20A fuse in the fuse box would work the same as having it in the spike itself. If you wanted to do that I dont know why it would be against the rules

but why would you want to? When a fuse blows that circuit is dead for the rest of the match. Breakers are better: if something momentarilly stalls a motor, or even if something gets across the motor terminals both a fuse and a breaker will protect the components and wiring

but only a breaker will keep trying to reset (and restore power) during a match.
