Jerry,

Protecting the wiring is a crucial element in choosing a fuse. You want the fuse to blow rather than have some wiring out under the layout melt or burn up. A thin drop wire might not be able to survive if there is a short circuit on the track, particularly if you have a beefy 10A booster which you chose to protect with a 10 Amp fuse. The fuse will indeed help protect the power supply, but the thin drop wire might instead start to burn up with only 5 A flowing through it. Whoops!
