For house wiring to be considered within 'code', there must be an additional circuit known as the 'ground' circuit. Grounding the house wire circuits provides increased protection against voltage spikes, short circuits in appliances or other unforeseen problems.
The ground circuit is recognized by wire with green insulation, connected to a silver colored screw on the side of receptacles.

The above answer is is giving the wrong impression of what grounding the electrical system is all about. The ground wire is used to provide a low resistance, low impedance return to the distribution panel of a fault current to trip the circuit's breaker and stop the current flow of the circuit.
The ground wire is NEVER connected to the silver coloured screw on a receptacle. This screw is reserved for only the neutral wire. The ground wire is connected to the green screw that is provided by the receptacle for only one purpose, grounding of the receptacle

∙ 13y agoIf the person touching the live wire is also touching ground then the current from the wire is flowing through them into the ground. You do not want to touch him bare handed since you will then also provide a path to ground through your body. There are lots of stories about two people getting electrocuted instead of one.
You need to make sure you don't make the problem worse. For example knocking the wire into a puddle or to a conducting surface that would put yourself or others in danger.
If the option is available the best way is always to turn off the voltage supply. This is not always possible. So you must assess the situation and see what risks you are willing to take. Things like a wooden pole (broom, etc) might be used to strike the wire away from person or push person from wire. Some have done rescues by looping a non-conducting belt around an extremity and pulling. In other cases it may be possible to body block the person from the wire so you could get a brief shock and this should be a last resort and with the realization you might be harmed. Basically use something that is non-conductive to remove person or wire from the death grip.
There are all kinds of disclaimers that goes with such advise. Basically, it is your decision and you should always consider self-preservation.

Is a brown electrical wire live?
If you don't know different for sure, then you must treat ANY electrical wire as if it's live, regardless of what color it may be.
Do you join brown electrical wire to red electrical wire and blue electrical wire to black electrical wire?
yes
How do electrical testers work?
An electrical tester is tool used to check if a wire is producing an electrical current. Usually you will just hold it to the end of a wire, if an electrical current is being "induced" a light will glow on the tester, this is a live wire.
How do you fix a light switch after two live wires touch?
There has to be more to this question for a good answer. For the most part a light switch has two contacts, with a wire at each one. One live wire and another going to the light itself. There is also a neutral wire return (from the light to the electrical panel). There is only one live wire in any electrical circuit. [Please, don't flame me with examples of multiple electrical sources in circuitry. We're talking about home lighting.] If somehow you shorted the live wire from the switch to the electrical box (ground) or to another wire in the box, it was only momentary and you can just proceed with replacing the switch. It's a good idea to turn off the power first.
What colors are electrical wires with number reference?
eletrical wire has 3 specif colour coding. As live wire ,neutral wire,earth wire. 1.live - red 2.neutral-black 3.earth - green. These are the specific color coding of eletrical wire.
When a live battery feed wire touches the metal frame shorting all electrical power out throughout the entire vehicle what is the problem that needs correcting?
insulate the 'live battery feed wire'. i.e.; electrical tape. Or, replace wire.
What does the live wire do in an electrical circuit?
The live wire in the supply cable carries current from the power station to the electrical device that you want to use. The current returns to the power station through the neutral wire in the supply cable. For safety reasons, on some electrical equipment there is also a ground wire - also known as an earth wire. It is connected to any metal parts on the outside of the unit, such as a metal case, and to any internal metal chassis, motor framework, etc. The ground wire is necessary to conduct away the current which could otherwise kill someone if a fault or an accident happens which damages the insulation of the live wire so that it touches any of those metal parts and gives them a high voltage. That would be very dangerous to the human users of the equipment.

When an electrical earthing wire is showing live what is the problem?
earth wire not cnnected from main earth
Do you join brown electrical wire to red electrical wire and blue electrical wire to black electrical wire?
yes
If the isulation on the live wire wears through the can become live but it wont stay live why?
The "can" or metal case of an appliance is supposed to be grounded so if the "live" wire touches it then the breaker or fuse will trip open and remove the power to the wire to prevent the person touching the appliance from being shocked.
What will happen to someone who is holding a live wire in the air and not touching the ground?
Nothing will happen , as the current always flows from higher potential to lower potential and if the person is touching only live wire then, there is no other path for the current to flow , but if the person touches the ground , the ground is at "0" potential, so, the current tries to flow from live wire to the ground via person , so the person gets shock in that case but not when a person is only touching the live wire and not the ground.
What is live in electrical engineering?
"Live" means that there is current running through the cable or wire or system in general.

What happens if someone touches a high voltage wire?
If they are grounded they get an electric shock or electrocuted. If they are not grounded or in simultaneous contact with the neutral wire, nothing. That's why birds can sit on a high voltage wire and survive; they are not grounded.
What causes a short circuti?
An electrical short circuit is when two bare wires touch each other. Or when one wire's insulation wears too thin and the bared wire touches the metal chassis of the device and is led to earth.
When you hold electrical live wire with your hand will you be shok?
if we are properly insulated with earth it would not affect otherwise we would got electrical shock
