Fuses are designed to carry safe amounts of electrical current and to rapidly break the circuit when current becomes too intense. Metals, because their valence electrons are not constrained, are good electrical conductors. As current is increased, resistance to electron flow causes the metal to heat and then to melt, breaking the electric circuit, and preventing damage to anything other than the fuse.
Carbon is also a good conductor. But as current increases and it becomes hot its resistance decreases. So it does not offer protection to the rest of the circuit.
Other materials, glass, ceramics, polymers, and semiconductors do not have free electrons and either insulators or poor conductors so they don't work as well in high current circuits.

What do each of the icons on a 1991 Pontiac Le Mans fuse box mean and how do you know what AMP fuses to use?
i do know what each of the symbols mean but you can tell what amp of fuses to use by looking at the top. you will find a number on there that you can use. just buy fuses with the same number. on that car they are either 10,20, or 30 amp fuses. i do not know what each of the symbols mean but you can tell what amp of fuses to use by looking at the top. you will find a number on there that you can use. just buy fuses with the same number. on that car they are either 10,20, or 30 amp fuses.

Constant temperature change due to fluctuating current/amperage draws weaken the metal inside fuses over time rendering the fuse unable to handle the rated load

How do you know if fuses are blown?
in a vehicle if fuses are blown a light comes on on your dash board . the light will indicate exactly what part , controlled by the fuse is affected. look at the fuse box it should have written on the face cover a guide to all fuses. pull out the fuse......inside is a thin wire ....if the wire is broken the fuse is no good. however in an emergency you can use a thin piece of wire , probably taken from your stereo speakers,use no more than three strands, and wrap it around the metal points of the fuse connecting both metal points and reinsert into the fuse holder . remember this is for emergencies only and is a short term solution. hope i have helped
