The colour red designates that the wire is used as a live wire. The neutral wire is identified as white in colour.
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.
The colour of the neutral wire in Australia is blue with marking N.
yellow?
The ribbed wire on a lamp cord is the neutral wire. On an extension cord there is no rib but the neutral wire is white in colour.
green
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.
In Bangladesh the color of live is green and neutral is blue and ground is black.
No, the colour white is used to identify the neutral in electrical distribution systems.
In North America the white neutral wire is never switched. This is because a split single phase secondary system is used. Opening a neutral could put two branch circuit loads in series with each other.
The black wire originating from a breaker box or fuse box is the live wire. However, in certain cases, the grey (or white) neutral wire can also be live. For example, the black wire may feed a lighting outlet, and if the neutral wire is broken on its way back to the neutral bar in the panel, then the neutral wire from the lighting outlet will be hot, because there is an electrical path from the black wire, through the light, and to the neutral. The point is, always check with a voltmeter before assuming the white or grey wire is not live.
The same rules apply to the whole of Europe. "Brown is live" , "Blue is neutral" and "Green/Yellow is Earth".
