While talking about splicing off a smaller wire from a larger one,
wouldn't the smaller branch require a separate fuse with a lower rating
to protect the thin wire in case of a short? And shouldn't this fuse be
placed where the smaller wire starts, at the place where the splice is?

Over here, we
don't solder mains distribution wiring (or at least, I
can't think of a time when you do). We get 'junction boxes' -- round
plastic boxes with (normally) 4 screw terminals inside. I've seen them in
up to 30A rating. Those are what is generally used to take a 'spur' off a
power cable.
Typically you don't do that here either, but it does a good job of
guaranteeing that crappy wire-nuts dont fall off and let the wires come
apart.
