The metal frame of the toaster is connected to earth (ground) so that should the line (live) conductor make accidental contact with that frame, the resulting earth-fault current will be large enough to operate the protective fuse or circuit breaker, which will disconnect the toaster from its supply. The earth wire is simply an alternative route back to the supply transformer for current.

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.
Is ground wire important?
Yes, especially for safety reasons.
What colour code for 3 pin plug in NZ?
The live wire is brown in coulor while the earth wireis green and yellow in color and neutral wire is blue in colour. Uses of these three wire: Live wire:It's connected with fuse.It carries a voltage which drives electric current through the electrical appliances. Earth wire:It is a safety device and protect us from electric shock. Neutral wire:It offers a return path by electric current.
Can a cut Grounding wire will starts a fire?
No. Get is connected as soon as possible for safety's sake.
How do I test for a ground wire?
Check the continuity of the ground wire from both the ends. Ensure the ground wire is properly connected to earth / ground terminals
What wire gauge is used for a toaster?
16 awg can be used for the toaster
Can earth wire be used as a neutral wire?
No, an earth wire has a specific safety role in an electrical circuit that does not allow it to be used as one of the two current-carrying wires.
What wire is safety device from safety shocks?
I think you mean the GREEN or GROUND wire. On a tool, it is intended to take dangerous electrical currents, and safely carry them to ground (instead of going through you) -It is also known as 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 is the third prong in plug for?
On a British plug it is the earth pin connected to the earth wire. This is safety feature to stop electric shock
How does connecting a safety wire to aeroplanes help?
conecting a safety wire is good because it is a safety wire and it makes the aeroplane sFER
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.
Explain why it is likely that wires in a toaster are made of copper?
it is likely that the wires in a toaster are made of copper and not silver,because wire is a type of conductor which would help the toaster resume working.
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.
What devices get a neutral wire?
All devices use two wire, the live and the neutral. These carry the current used by the device. Most devices also have an earth wire for safety, which carries no current until a fault occurs and then the fault current in the earth wire might save someone from being electrocuted.
What is earthgrounding wire?
Earth wire (or earth grounding wire) is a safety system which helps prevent electric shocks. It is connected to the electrical cable of an appliance.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.
What is an equipment ground wire?
An equipment ground wire will discharge the excess voltage due to electrical surges to protect the circuit from damaging.For a full explanation of how this works see the answers to the Related Questions shown below.
