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.
In the North American market, solid core is used for home wiring where flexibility is not a problem with installation. Conduit systems use stranded wire because of its flexibility when being pulled into a conduit system that has multiple bends between pull boxes.
It all depends on where the wire is installed!In Direct Current systems such as in a car or truck a black wire may be negative but that should not be assumed. Always check first, using a voltmeter.In Alternating Current mains wiring systems it may be:"Hot" in USA or Canada, or other countries which use the same 60 Hz system"Neutral" in the UK in mains wiring done before 2005. (After 2005 new mains wiring has to use Blue for Neutral, as for the rest of the European Union.)IF YOU ARE NOT ALREADY SURE YOU CAN DO SOME ELECTRICAL WORKSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do any such work yourself,always turn off the power at the breaker box/fuse panelBEFORE you attempt to do any work ANDalways use a meter or voltage indicatorto insure the circuit is, in fact, de-energized.
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.
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.
The following applies to the UK Blue wire goes to neutral Brown wire to live Yellow/Green stripe wire to earth

In household wiring, brown insulation is typically used for live or hot wires. It is important to always verify with a voltage tester or consult a professional before working on any electrical wires to ensure safety.
In the North American market, solid core is used for home wiring where flexibility is not a problem with installation. Conduit systems use stranded wire because of its flexibility when being pulled into a conduit system that has multiple bends between pull boxes.
In electrical wiring, the color brown typically represents the live or line wire, which carries the current to the appliance or device. It is crucial to follow the appropriate color coding to ensure safe and correct installations. Remember to always consult with a professional electrician or refer to local electrical codes for specific guidelines.
A phase wire is the hot wire in a circuit if looking at single phase that would be the live (brown in the UK). If you are trying to find out which wire is your phase wire use a voltmeter connect the black lead to earth and red lead on the wire to be tested. If the circuit is on and you have a phase wire you will read voltage on the meter. If the circuit is off or you have the neutral(blue wire in the UK) you will read little or no volts.Notice electricity is dangerous always use common sense if you don't know what you are doing find someone who does failing that put a hand in your pocket you will have less chance of killing yourself.Answer'Phase' is the incorrect name widely used in place of the correct term, 'line'. The current version of BS 7671(2008), the IEE Wiring Regulations, has, at last, recognised the misuse of the term 'phase' in its previous editions.In the UK, a single-phase AC line conductor has a nominal potential of 230 V with respect to the neutral. In Europe, a single-phase line conductor is normally colour-coded brown; in three-phase systems, the three line conductors are colour codes brown, black, and grey.
In the UK, the old wiring colours were... Live = red, Neutral = black, Earth = green.
The three colours used in the UK are: blue (live), brown (neutral), yellow and green stripes (earth). The standard UK domestic voltage is 240 volts.
This is not true in all plugs it all depends on the manufacturer and the product. Plug wires come in all different colors such as red, black, brown, yellow, blue, and so on. So as I said the wire being brown is indicative of a certain manufacturer or product.
