Which is the Hot wire and which is the Neutral wire if the wires you see are a Brown a Blue and a Yellow-Green wire?

It depends on how the wires are hooked up.
In general, the accepted practice is to use the green/yellow wire for ground. The blue wire is neutral. The brown wire is hot.
But saying this does not guarantee that the previous wire monkey did it right, especially if they followed the advice left here earlier... Click on the View Discussion button below this answer to see the first answer that was given to this question! So make sure you test your wires before using them to power a new circuit.
Cheap circuit testers are available at any local hardware store for just a few dollars. Remember that a light bulb isn't a tester - it will still light up if the wires are crossed.
This could mean that your light FIXTURE is HOT - potentially killing you when you go to change it. Even switching off the lights will not remedy the situation, since you're breaking the circuit to GROUND. That means you have a floating Live wire in the fixture, "waiting" for you to touch it and complete the circuit to Ground.
So, the moral is: DO NOT rely on colour-coding. Test your wires with the right equipment.

Which leads to the follow-up moral: Make sure you get your work inspected or have it done by a qualified and licensed electrician.
NOTE: the above "accepted color coding" where BLUE is the neutral is generally in Europe and countries other than the USA. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS.If you do this work yourself, always turn off the power
at the breaker box/fuse panel BEFORE you attempt to do any work AND
always use an electrician's test meter having metal-tipped probes
(not a simple proximity voltage indicator)
to insure the circuit is, in fact, de-energized.

Where do you connect blue and brown wires in European and UK wiring?
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.
What brown colour wire indicate in a electric iron?
Brown is the "hot" wire and blue is the neutral on a UK 220 volt power system.
Which colour wire is live in UK wiring?
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.
How do you measure continuity on long wires?
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.
How do you wire a red yellow brown white wires to a Black Green and white?
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.
What are blue brown and yellow wires?
Blue - Neutral Brown - Life Yellow/Green - Earth
Which is the Hot wire and which is the Neutral wire if the wires you see are a Brown a Blue and a Yellow Green wire?
Brown = Hot Blue = Neutral Yellow/Green = Ground
What is the blue wire for in a three pin plug?
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.
Which wires are the live neutral and earth on a Chinese cable where the colours are brown blue and white?

Where do you connect blue and brown wires in European and UK wiring?
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.
How do you connect the colors blue brown pink black purple orange yellowgreen?
to collect all these colours put them all in a bowl and mix them. Blue and orange are complimentary colors. They make brown.
What are the three wires in a plug called?
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
If you have a circular light bulb there is two wires black and red you want to replace them with a standard power cable blue brown and yellowgreen Which goes where What is black and what is red?
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.
What are the names of the three wires in a plug?
Live Wire = usually brown, if not then its grey or black. Neutral Wire = Blue Earth Wire = green and yellow striped
How many brown wires in us 3 phase?
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.
How do you wire brown black and blue to black yellow and 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
Which is the Hot wire and which is the Ground wire if the wires you see are a Brown and a Blue wire?
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.
