The earth wire connects the metal frame of the electrical appliances to the ground. The convention is to have green colour for earth wires. The purpose of earthing is that in case of an insulation failure in some appliance, this wire connected to the metal body will provide a path for the current to flow on the ground. In absence of earth wire, this fault current would have flown through the body of the operator, causing electrical shock.

∙ 14y agoThe earth wire is a safety device to prevent electrocution,especially in an electrical device with a metal frame or cover. A live wire accidentally touching the case will blow a fuse. If you are touching the case at the time of the fault the lower electrical resistance of the metal and low earth resistance will direct the current away from a relatively high resistant human body.

∙ 11y agoearth wire know as the ground wire which is either bare, green or green with yellow strips. is the safety of the electrical system. it is used to bond all electrical bodies together, other than that is energized. the ground wire ultimately is connected to the grounding system which acts to curry all electrons (excess power) which could linger on electrical bodies to the ground making sure there is no danger of being shocked when touching those bodies.
IE, when in the winter power get static electricity build up on their bodies which when they tough another person or grounded body they get a small shock!! the earth wire makes sure there is no build up of any kind on any electrical equipments
AnswerAn earth conductor ('ground conductor') provides a low-impedance return path to the source, in the event of the conductive parts of an electrical component making accidental contact (e.g. due to damaged insulation) with the line conductor. The resistance of the earth conductor must be such as to enable the circuit's protective device (fuse, circuit breaker) to operate in the event of such a fault, thus protecting the circuit.

∙ 11y agoThe purpose of the earth wire in a 3-wire power installation is to provide a diversionary safety path for fault currents.
Consider an old fashioned 2-wire circuit in a metal box. If the interior insulation is breached, the holder of the metal box will be connected to the power line, and provide an alternate return path in parallel with that provided by the internal circuit and the neutral wire.
With a ground wire, that fault current goes directly back to the power box without shocking the user.

Earth wire has a green insulation around it.it used as a safety wire when short circuit happens. The Earth wire is connected to deep down the earth and is connected to a metallic plate. This is because when high amount of current passes through it does not harm the user

When charge are able to flow directly from the circuit into Earth a ciruit electrically?
That is what the Earth wire does. Normally it does not carry current but it has this important safety function.
Can you connect a 6mm earth wire to a 2.5 mm earth wire?
A 6 mm earth wire can be used to replace a 2.5 mm earth wire, but if there is an existing 6 mm earth wire it must be 6 mm all the way to the earth, and not replaced by a smaller wire between it and the earth connection.
What is the function of a electric socket?
It allows you to disconnect the load without having to unplug the flexible cable.
What is the function of Wire Gauze?
it helps in providing constant heat
Can loose neutral wire effect the operation of Earth Leakage Circuit Breaker?
Yes, a loose neutral wire can effect the operation of Earth Leakage Circuit Breaker.

What is difference between nutral and earth wire?
A neutral wire provides a return path for the hot lead while an earth or "ground" wire is provided as a safety function only that is not normally intended to carry current except for the purpose of operator protection.

Wire that discharges excess electricity to the earth?
It is the earth wire
When you connect earth wire in ceiling light does not work when connecting earth from light direct to earth wire coming from ceiling trips out when take earth wire out light works?
By earth wire I am assuming you mean the bare wire and that a black and white wire are connected to the light. If when you connect the earth wire and breaker trips then there is a short between black and earth. It could be a bad ground connection, an internal short in the light fixture where black wire "hot" is connected to metal on the fixture through a nick in wire.
What does green wire indicates?
Earth wire
How you provide earthing by three pin plug?
The three pins are live, neutral and earth. The live and neutral carry the current, and the earth should carry no current. Its function is to connect together the external parts of all pieces of equipment so that it's impossible to get a shock by touching two items at once. Another function is to connect the external parts to an earth rod and to the gas and water pipes in the property. Another function is that if an internal fault allows a live wire to touch the case, enough current will flow to blow the fuse or trip the circuit breaker. So in different ways the earth pin/wire provides an important safety feature. In Europe the earth wire is coloured green and yellow.
What are the function of wire stripper?
They are for stripping the insulation off electrical wire.
Why is your earth wire is glowing on the live circuit?
In the visible spectrum or the infrared? Either way, if your earth wire is glowing you have a problem. Your earth wire is not intended as a current carrying wire. If the wire is loaded to the point that it glows then your circuit/breaker is not wired correctly and the earth wire is being used as an unintended path and is a hazard. Earth wires are not sized properly to carry current.
What is the third green wire on an electric drill is the wire?
it is the earth wire
How can earth wire prevent electric shocking?
large current flows from live to earth wire.
