In the US older 2-conductor house wire has a white-insulated and a black-insulated wire. The white wire is the neutral and the black is the hot wire. Newer house wire has a third bare copper wire to serve as the ground wire. Insulated ground wire has a green jacketing on it. Red wires are for switch legs. You want to be sure that whomever did the wiring didn't flip the colors around. You can do this by checking the fuse or breaker box - the white or neutral wires should all run to the multi-neutral ground bus bar and the black or hot wires should each go to their respective circuit breakers or fuse sockets. On your switches and recepticals, the gold screw is for the black, or hot wire, and the silver screw is for the neutral. The green screw would be for the ground wire. Mostly, use a qualified electrician to do any work unless you are quite handy, have all necessary tools and fully aware of all safety precautions and code requirements that may exist where you live.
US standard
Earth is green, live is black, and neutral is white
UK
Live is brown, neutral is blue, and earth is green with yellow stripe.
Since in the US the earth is referred to as the ground wire it is assumed you are asking about UK standard.
In Bangladesh the color of live is green and neutral is blue and ground is black.
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.
yes,because its a primary color
You would find a live electric wire, with a neutral and usually also an earth wire, in any place where electricity is used. The wires are colour coded differently in different areas but in Europe live is brown, neutral is blue and earth is green/yellow.
The cable to a light bulb (with a plastic bulb holder) in a house, etc, usually has just a live and neutral wire. If a brass or metal bulb holder is used, an earth wire is advised for safety reasons.In the UK, mains power cables and wall sockets are of the three pin types, with the live (bRown wire) to the right, and the neutral (bLue wire) to the left, and the green and yellow striped wire to the earth pin.

In the UK, the old wiring colours were... Live = red, Neutral = black, Earth = green.
The wire color indicates what type of voltage the wire is carrying. Color coding is important for safety because the live, neutral and earth wires must never be confused. Color codes differ between Europe and USA etc.
The green and yellow is the earth wire The brown is the live wire The blue is the neutral wire A poem to help is: The brown live cow drinks from the blue neutral water and eats the green grass from earth
Green with Yellow Stripe Wire - Earth Wire (E) Blue Wire - Neutral Wire (N) Brown Wire - Live Wire (L) When you look at the plug with the terminals facing towards you: /\ / \ / E \ / \ / \ / L N \ ------------------
yes,because its a primary color
The brown wire is live (Mr Brown is a live wire!)Blue is the neutral wire for the return current. Green/yellow is the earth wire.

red = phase, black = neutral, green = earth
The following applies to the UK Blue wire goes to neutral Brown wire to live Yellow/Green stripe wire to earth
