Not always, the electrical code is quite specific as to the type of installation where the ground wire needs to be insulated and in what type of installation the ground wire can use bare copper.

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.
Why insulation is needed on current carrying conductors?
To prevent the wire from getting short circuited to ground or even to other wires.
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 is copper wiring coated with insulation?
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.
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.
How do you wire an older 2 wire 30 amp compressor to a 3 wire 30 amp dryer plug?
I am guessing that the dryer is 220-240 VAC as is the compressor. I also assume that the third wire on the dryer is a ground. You need to make sure that the metal chassis on the compressor is not connected to the two wires. You then need to create a covered junction box where you have the two existing wires and a ground wire that you connect to the compressor metal chassis with a screw type connector. Ground wire should be 10 AWG. Now you have three wires. Connect the two hot wires of supply to two original wires on compressor and ground wire to the chassis ground.
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.
What is the color of insulation over an earth wire?
The insulation will be green in colour. Also bare copper can be used as a ground wire.
