For anyone questioning last years rules, the fuses were allowed on custom circuit boards for local protection but the custom circuit itself needed to be protected by a 20 amp breaker. Why a breaker, because the rules don't allow you to run out on the field during a match and replace a blown fuse.
As others have pointed out, the GDC is aware of the complications of using smaller wire and smaller breakers. However, we will know tomorrow if they will allow something less than 20 amps and #18 wire.
