In electrical wires the plastic insulates the wires to prevent a short circuit or electrocution.
Different coloured plastic can aid identification of individual wires.
The plastic coating can also prevent rust and prolong durability.
Because plastic is a non-conductor and as such does not conduct electricity.
They're not. They're usually copper or aluminium, which are metal!
To prevent them from touching each other and/or to protect them from the environment.
The plastic keeps the wire from shorting and starting a fire. Old homes used to have non-insulated wire ran through the attic's and carelessness or pests could short them and start a fire.
Keeps the electricity from going places you don't want it to.
so you don't get an electric shock

There are many advantages that plastic gutters have over metal gutters. This includes the fact that they are easy to assemble, they are cheap and they do not require specialist joining techniques.
Ductility. A metal can be drawn into wires as the atoms of a metal are packed regularly in layers and they are of the same size. Hence when a force is applied, layers of atoms can slide over one another.
There is no problem using over sized wires on a breaker. It is only when the wires are undersized that the trouble begins. Oversize wire on a breaker is very common practice when overcoming voltage drop on a circuit.
The size and composition of fuse wire is designed to "burn through" in an over current situation. That works fine as long as the current is lower than the fused rating. If you were to use the wire in the circuit then all your wire would essentially disintegrate in an over current situation.

Plastic is a bad conductor of electricity. Metals are good conductors of electricity. You get the metal wires coated by plastic. So when you touch the wire, you do not get the electric current. This nature of the plastic protects you from getting electrocuted.
You have a short circuit/over current problem with the circuit. If the wires are not touching metal, then the starter may have failed.
Insulation can be put over wires to prevent short circuit breaker trips.
Hair grips can be made with either plastic or metal. Some of them have plastic coating over the top of the metal.

Plastic food containers are usually see-through and allow people to see what is in the container. Plastic containers have an advantage over metal in that they do not rust. Plastic is also lighter than metal.

On my 2003 I believe it is under the drivers side dash, right near the break padel. It has a plastic cover over it covering the metal cased breaker.
It is typically better to use plastic knobs over metal knobs on kitchen furniture. The plastic knobs tend to not scratch the floor as much as metal knobs.
Because the amount of heating depends on how much current is in the wires. So you set the CB to cut the current if it exceeds the rated current for that wire.
