About using copper wires as fuses
Air can also play a protective role, but there are "open probability failure", and the choice of appropriate fuses are not "failure" problem.
On the market for the sale of (high-quality) 2x16x0.15 wires in a single copper wire (diameter 0.15), fuse current of about 3A, inferior line is even smaller, two Amdo broken. The larger fuse is a slotted sheet of copper.
Copper wires can be used as fuses. Copper sheets can be used as fuses! Fuse insurance is not insurance, the key is to see the fuse current instead of material, thin thin copper wire, the excessive current, as long as the wire diameter and the fuse current adapter is no problem (read more people do not adapt to this point).
