Overheating is a fire hazard eliminated by a fuse or circuit breaker
which limits current to a safe value.

The power circuits in your house may be protected with 15-amp breakers.
The wiring is then safely chosen to carry 15 amps with no danger that
the wires will overheat.

15 amps in your wall wart may set it on fire with no help from your
load-center. This can be prevented with a fuse or breaker on the wall
wart by itself which limits the current to less than it takes to set the
device on fire.
