The following applies to the UK Blue wire goes to neutral Brown wire to live Yellow/Green stripe wire to earth
The colour of earth wire is yellow and green now you may ask why well the reason is that the green one as well yellow color is used as Earth's wire. This is because the green and yellow type wires are for grounding purposes or we can say earthen purposes. Green colored wires are used in an electric circuit for grounding.
Brown is the "hot" wire and blue is the neutral on a UK 220 volt power system.
The insulation will be green in colour. Also bare copper can be used as a ground wire.
Green, or yellow and green striped.
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.
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 two white wires. one is for lambda heater.along with the grey wire.the other white wire is lambda itself it gets its earth from the exhaust. and the black wire is the signal wire
The ground conductor is colored green to be identifyable anywhere in the circuit
If you're asking about UK three prong plugs - the earth cable is green and yellow, the live is brown and the negative is blue.
The same rules apply to the whole of Europe. "Brown is live" , "Blue is neutral" and "Green/Yellow is Earth".
These colour wires are used in European and UK wiring. The blue wire is used to the identify the neutral conductor and the brown wire is used to identify the "hot" conductor.In Canada and the US. The white wire is used to the identify the neutral conductor and the any colour but green is used to identify the "hot" conductor.
