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.

What advantages do plastic gutters have over metal gutters?

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.


What means that metal can be drawn into thin wires?

The ability for metal to be drawn into thin wires refers to its ductility. Ductility is the property of a material that allows it to deform under tensile stress, such that it can be stretched into a wire without breaking. Metals that are ductile can be drawn into long, thin wires without fracturing.


Why fuse wires are not used in a circuit containing electric 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.


What do black dots represent in a wiring schematic?

A black dot in a wiring schematic diagram at a wire intersection represents a position where circuit wires are joined together. At a wire intersection where there is no black dot the wires cross over each other with no junction.


How is the rating of the branch circuit protective device affected when conductors used are of larger size than called for by the code?

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.

How does plastic over metal wires prevent being electrocuted?

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.


Why does the starter solenoid fuse keeps blowing on your 2000 dodge ram 1500 laramie?

You have a short circuit/over current problem with the circuit. If the wires are not touching metal, then the starter may have failed.

What are the advantages of using a plastic food container instead of a metal one?

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.

It is better to use plastic knobs or metal knobs on kitchen furniture?

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.


How do circuit breakers keep the wires in an electrical circuit from over heating?

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.


What advantages do holding tanks made of plastic have over metal ones?

The main advantage of having a holding tank that is made of plastic over metal ones would be that it would last longer. One that is made of metal could rust and corrode but a plastic one would not have those problems.
