Viewed from the solder side, with ground on the bottom, left is neutral and right is hot. It's just as if you were looking into a wall outlet.

It's a valid question, though, since it's good practice to wire up the hot--or the conductor that would be the hot if you plug into a properly-wired outlet--to the unit's line fuse.
The line fuse should be the first stop after the line enters the chassis, before the on/off switch, before anything else.

If your stuff is wired properly, it doesn't.

If your fuse is in the neutral, and the hot is shorted to the (grounded) chassis, the fuse won't blow. The current has found a path bypassing the fuse. That's why it's good practice to fuse the hot. You can't control the wiring outside of your box, of course. Some manufacturers play it extra-safe and fuse BOTH hot and neutral, although this is fairly rare.
