∙ 11y agoStraight to the Point Answer:
To save your life, and prevent you from starting a fire during some types of electrical faults. To put it bluntly, if you cut it off, you could kill someone and/or burn your house down.
A non-technical answer
The ground wire is connected to the outside metal casing of the appliance. It guarantees that if somehow the Hot wire in the appliance shorted to the case, you won't get a shock because the short will go to ground and not through you and will trip the breaker.
More technical answers
The purpose of the ground wire on an appliance or in a house branch circuit is to provide a low impedance low resistance return path for the fault current to return to the distribution panel. This high return fault current will cause the circuit's breaker to trip and disconnect the fault.
<<>>
The ground wire usually doesn't have anything to do with the normal electrical functioning of an electrical appliance but - because the ground wire is connected to the chassis or casing of the appliance - if an electrically 'hot' wire breaks or its insulation chafes so that it touches the chassis or casing, it will be shorted to ground via the ground wire, causing a very high current to flow in the 'hot' wire.
That high current will cause the circuit breaker to trip or a fuse to blow, thus cutting off the current and preventing the chassis or casing from electrocuting the user. Shutting off the current should also prevent the wires in the circuit from heating up so much that they catch on fire. Such a fault can easily be the cause of a serious house fire.

Hot wires in home wiring are normally colored and ground wires in computers are normally colored?
Hot wires in home are normally colored black. And ground wires in computers are normally colored black as well.
How do you install a light fixture that has two brown wires and a ground?
So long as you conect the ground/earth to the green wire/earth You can conect the other two wires any way around you like.
Should you attach the ground wire to the black wires?
in a home noin a car yes
Why 4 wires for dryer?
The dryer is a 240v dryer so two of the wires are your hot wires, or the ones with power on them. One is your ground wire. And the forth is your neutral.
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.
Hot wires in home wiring are normally colored and ground wires in computers are normally colred?
hot wires are black, white wires are ground
Hot wires in home wiring are normally colored and ground wires in computers are normally colored?
Hot wires in home are normally colored black. And ground wires in computers are normally colored black as well.
What if the light fixture has two copper house wires?
If you mean 2 bare copper wires those are the ground wires. Tie them together and then connect the light fixture ground wire which will be green or bare copper to those ground wires.
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.
How do you install a light fixture that has two brown wires and a ground?

How many wires supply electricity to your home?
There are three wires supplying power to your home two line wires @ 110 volts each and one nutral.
What is 2 wire plus ground 240V?
With one interpretation of this question, the answer would be two 120V wires and a ground.

Can you install two ground wires in the same raceway?
There should be no reason to install two ground wires in the same conduit. Code requires that only a single path should be required if it is to carry a fault current. This ground wire should be single and continuous from the device back to the distribution panel. It is the fault current that is carried on the ground wire that trips the breaker or fault protection device. Don't confuse grounding wires with bonding wires.
