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.
Brown is the "hot" wire and blue is the neutral on a UK 220 volt power system.
In a flexible cable, the brown is the "line" voltage and blue is "neutral", often tied to ground at the mains panel. In fixed cables, i.e., "behind the walls", the UK wiring standard changed in 2004, where it now MATCHES the flexible cable: brown is line, blue is neutral. Prior to that, blue, red or yellow were acceptable LINE conductor colors and black was neutral.
Easy: make sure both ends of the cable are completely disconnected. Go to one end of the cable, twist 2 cores together for instance brown and blue. Now go to the other end of you cable and test the continuity between the brown and the blue cables. This will verify both of these cables are continuous.Now untwist the cables, and twist another pair together, say brown and green/yellow. Test again between these cable and you're done.If you are fault finding, you can use this to figure out which cable is broken.Say you get no continuity between brown and blue.Set the test up again, test brown to green/yellow and you get nothing again.Set the test up again, test blue to green/yellow... assuming you get a continuous signal here you can assume you have a problem with your brown wire.
Answer for UK, Europe and countries running a 50 Hz supply service.It all depends on which connection you are using. Alternating Current (AC) or Direct Current (DC). In AC there are generally two modes of transmission. Single Phase or Three Phase. In case you don't have 3-phase connection just combine yellow and green.According to Standard, Green is for the Earth Wire and Red is for the Live wire. Blue or Black is for the Neutral Wire. So best option is to combine the Yellow and Green.
Blue - Neutral Brown - Life Yellow/Green - Earth
Brown = Hot Blue = Neutral Yellow/Green = Ground
In the UK Brown is the live, blue is the neutral and green/yellow is the earth. The live and neutral are the two wires that normally carry the current.

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.
to collect all these colours put them all in a bowl and mix them. Blue and orange are complimentary colors. They make brown.
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
the old colours are black and red, they have been replaced by the European harmonisation of brown and blue. the black is now the blue the red is now the brown and the yellow and green is the CPC ( circuit protective conductor) or more commonly known as "earth" but that's a wrong identification of it.
Live Wire = usually brown, if not then its grey or black. Neutral Wire = Blue Earth Wire = green and yellow striped
The European standard calls for the three line conductors to be colour coded brown, black, and grey respectively. A neutral conductor is colour coded blue.
I assume you are asking about matching up the colors. The only to know for certain is to trace the wires or test them for currant.Typically in a ceiling fan or exhaust fan the black, yellow, and blue are black=fan, blue=lighting, and yellow=neutral. Typically brown, black, and blue are all used as hot wires or switched wires. The brown or the blue could be standing in for neutral so, again, the only way to tell and be certain is to test each lead with an electrical tester.In electronics, these colors could be anything.Normally when you have these combinations there are special plugs at each end of each set but I assume they are missing so you may have to contact the manufacturer or call an electrician.Hope this helps.Gibbous
Brown = live (hot) - (equivalent to Red wire) Blue = neutral - (equivalent to the Black wire) Yellow and green = earth. --------------------------------------------------------------------------- However never rely on the wire colors - you should test the wires with a meter to be sure that the person before you has not made a mistake further back in the wiring.
