Fast Blow fuse, use 2x current draw. Slow Blow fuse, use 1.25 times the current draw. Fuses can operate up to 1.5x the fuse current rating for up to 20 minutes.
Personally, I use Slow blow at as close to current draw as possible with capacitor input power supplies. Choke input power supplies not having a high input charging surge, I use Fast Blow at as close to current rating as possible. Never had a fuse fail.
