Well yes, when a circuit is interrupted, it is just my nature to find out why the interruption. If you don't respect the laws of electrical nature and theory, why bother to be concerned about fusing any type of circuiting?
They are there for our protection as well as equipment protection.
Mechanically, in a fuse there is a physical metal meltdown, a permanent disconnect.
With a breaker the disconnection can be reset many times, yes, and that is where human complacency is greatest. We are taught to trust these pieces of equipment as "foolproof, never failing." That is why people die and get hurt by electricity..you have to know why the circuit failed.
Hence, the need to constantly be wary when testing. Fuses eliminate this reality altogether and that is why they get my vote. Others may not agree.
