No, the fuse is to protect people. That means protecting the wiring, device,
and appliance to avoid fires. The rated current of an item is not necessarily
the size of the required overcurrent protection.
The example does not demonstrate undersized wiring. It demonstrates too few
circuits. As stated earlier, you can use one large circuit to feed them all,
provided you install the smaller protection where you tap off to feed the
loads, but this is not the common way of circuiting. This method is normally
used where it's not feasible, or desirable to run individual circuits.

In vk land the reason for the fuse is to protect the WIRING not the
device as per u could have 3 devices on one circuit say each @ 5 amps
es ur c/breaker is rated at 15Amps just ok for ur wiring "but" say u
have 3 devices @ 10Amp =30Amps then your wiring is under rated..if ur
using 15Amp rated wiring for that circuit!!
