Why insulation is needed on current carrying conductors?
To prevent the wire from getting short circuited to ground or even to other wires.
What is a poor conductor of electricity and is used to coat wires?
In low voltage wires, the insulation factor of the coating determines the wire's voltage rating. A wire coating of cross linked poly vinyl is used as an insulation. High voltage transmission wires uses no coating on the wire
What is the purpose of insulation on the electric wire?
So that the living organisms and other wires/metals are not affected by the current in a given wire. In the absence of insulation two wires coming in contact may cause short circuit and also there is a risk of death of the living organisms coming in contact. There is one more reason that insulation minimizes charge leakage from the wire.
Can a ground wire be connected to the white neutral in Clearwater Florida if no ground wire ia available?
Yes, if there in no ground wire that is acceptable on a home with no ground wires.
Why should there be no bare wire exposed after a wire nut is used?
Leaving any exposed bare wiring can lead to short circuit and breaker tripping. Most of the times wires in junction boxes are jammed into the back of the box. This is to allow for a device such as a switch or receptacle to be installed. Leaving exposed wire showing below the wire nut could allow contact with other exposed wires or it could come in contact with the bare ground wire which is also jammed in there. Good workmanship should prevail, only strip as much wire as needed to twist the wires together. Then install the wire nut. The skirt of the wire nut should project down over the insulation of the wire by a quarter of an inch. If it does not use a larger wire nut. This will provide full insulation protection to the wires in the junction box.
What are wires in a circuit covered in?
There are a variety of wire coverings depending on what the conductor is used for. There are also different wire coverings for different temperatures where the conductor will be used. To answer the question the wires in a circuit are covered in insulation.
Why does an engine miss?
A plug not firing for some reason. this may be do to bad wires, insulation cracks cause spark to jump from wire to wire, or wire to ground.
Does a wire have to be insulated for electricity to flow?
No, overhead primary wires have no insulation on them and they carry the electricity to the consumers very well. Wires with no insulation on them just need more clearance space around them and between them to prevent the wires from short circuiting to each other or to ground.
Why insulation is needed on current carrying conductors?
To prevent the wire from getting short circuited to ground or even to other wires.
Why are electrical cables and wires always covered with rubber or plastic?
AnswerThe rubber or plastic serves as electrical insulation (because they are poor conductors). Without insulation, the electricity running in a bare cable would leap over into any other electrically conducting material it touched. With enough voltage, a human could be electrocuted.Electrical signals would disappear and get lost, causing equipment to fail.AnswerSo the conductor is insulated against possible metal contact & prevent a short if it's grounded.AnswerAll household electric wires are covered with plastic and rubber. This is called insulation. It keeps the potential of the wire from returning to ground (short circuit) before being used by the load. The higher the potential (voltage) the greater the insulation factor has to be. Bare wires in transmission towers also use insulation in the form of air. To use this method, engineered clearances have to be maintained between the conductors.AnswerAll electrical power wires are covered with an insulating material. This is to prevent the potential on the wire from going anywhere except to the load.Electrical connecting wires are covered with plastic to prevent the wire under the covering from shorting out against each other or shorting out to ground. The electrical terminology for this covering is the wire's "insulation".These days most electrical wires are covered with a flexible plastic (rubber starts with the sap from a rubber tree; plastic usually starts with a petroleum base).AnswerThe main purpose of the "cover" (insulation) is to keep the wire from shorting to other objects.The plastics used generally have a good mix of the following properties:It is flexible so the wire can be flexed and bent.It is inexpensive and easy to apply to the wire during manufacturing.It has resistance to chemicals and UV light.Sometimes it's also important for it to resist abrasion or temperature extremes, or submersion in water.You can get wire with different types of insulation depending on what you need it to withstand.
What is insulate wires?
A wire which contain an insulation coating on its is known as insulated wire. Due to insulation coating short circuit condition minimizies.
Why is copper wiring coated with insulation?
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.
What is a poor conductor of electricity and is used to coat wires?
In low voltage wires, the insulation factor of the coating determines the wire's voltage rating. A wire coating of cross linked poly vinyl is used as an insulation. High voltage transmission wires uses no coating on the wire
Can you get an electrical shock if you touch a wire covered in plastic?
No, the covering on the wire is insulation. This insulation is used to isolate the wire from any grounding medium, this includes a person. It is not a good idea to go around touching wires as there may be a nick in the insulation. If the nick goes all the way through to the conductor, and you touch that specific spot and you are grounded you will get a shock as you become part of the conductor.

Which plastic is used for making wire insulation?
Electrical insulation on a wire or cable composed of plastic. Most wires and cables use plastic insulation. Some other types of insulation used on wires and cables are: enamel, cloth, natural rubber, gutta percha, ceramic, etc.
Should you attach the ground wire to the black wires?
No, the ground wire should be attached to the green or bare copper wire. The black wires are typically live or hot wires and should never be connected to the ground wire.
