Take the fuse out, it is a safer option.
it is possible that the fuse has not blown and it still has power to it but no return path because the wire has been blown/chewed apart.
Also, turn the power off at the main switch before climbing under there, it is possible that there are more bare cables that have been chewed and you don't want to come into contact with one if the power is still on.
If it were me, i would take a torch and a 410 gauge shotgun, just in case there are any more raccoons, rats, snakes or any other things that may fight back!!
