Because if the wire is "hot", that is, has electricity flowing through it, and you touch a bare wire, then YOU become the "ground" and complete the circuit. This will cause at the least a bad shock, and at the worst it will cause death. The "ground" wires are bare, but that is because they do not have electricity flowing through them unless something shorts out (ie a "hot" wire which is normally black or red in color touches a ground or neutral wire which is normally white. The "ground" wires are either bare or have a green coating.
Copper wiring is coated with insulation to protect against electrical shock and to prevent short circuits. The insulation helps to prevent the flow of electricity to unintended paths and prevents the wire from coming into contact with other conductive materials.
Wire without insulation is only supposed to be used for grounding purposes. It is the same as wire with green insulation. but is easier to connect to multiple outlets as it does not need stripping.
The uninsulated (or green insulated) wire is the safety ground wire.

Is copper in electrical wiring number one copper?
No, the term "number one copper" usually refers to clean, unalloyed, and uncoated copper wire with no insulation. Electrical wiring typically consists of copper wire with insulation or coating, so it would not be classified as "number one copper" in the scrap metal industry.
What damage can heat cause to copper wires and its insulation?
Excessive heat can cause copper wires to become brittle and lose their ability to conduct electricity effectively. It can also degrade the insulation surrounding the wires, leading to potential short circuits or electrical fires. Heat can also cause the copper wires to expand, potentially compromising the connections within electrical components.
What is it called when a wire is coated in plastic to surround the wire are called?
Insulation
What goes up first in new construction wiring or insulation?
In new construction, typically the wiring is installed first before the insulation. This allows for the electrical components to be safely and properly placed throughout the structure before the insulation is added to the walls.
Where is copper wiring in a yacht?
Stop trying to steal copper wire.
What are the advantages of PVC Coated Copper Tubes?
PVC Coated Copper Tubes prevent corrosion and provide insulation, making them suitable for plumbing and HVAC.
How do PVC Coated Copper Tubes benefit plumbing and HVAC systems?
PVC Coated Copper Tubes provide corrosion protection and insulation, enhancing longevity and efficiency in plumbing and HVAC systems.
What is the price paid for copper wiring in san Jose?
depends on the size, type of insulation, quantity purchased?
Is copper in electrical wiring number one copper?
No, the term "number one copper" usually refers to clean, unalloyed, and uncoated copper wire with no insulation. Electrical wiring typically consists of copper wire with insulation or coating, so it would not be classified as "number one copper" in the scrap metal industry.
What is the advantage of using insulated copper wires in wiring circuits?
Copper is : a good conductor, easy to work, and relatively cheap. And you use the insulation to help avoid shorts.
Are pipes coated before insulation?
No.
Is there an oven available to melt insulation off of copper wire?
Well insulation has a higher heat tolerance than copper. So melting it would DEFINITELY NOT be the way to go. If you can, snip a piece off and slip the rubber insulation off. If you can't, get a professional. wiring is not something you should play around with. and melting is definitely worse.
Is penny copper?
modern pennys are only copper coated

What are the three use of copper?
Copper coins (though are more an alloy than pure copper nowadays), copper pipes in plumbing, copper plus tin and other metals to produce bronze. There is also the copper used to produce electrical wiring. There is even aluminium wires clad (coated) in a thin layer of copper for electrical use. The list could go on...!
Why is a gold coin shiny?
it is coated in copper. copper prevent corrosion.
What is it called when a wire is coated in plastic to surround the wire are called?
Insulation
