The blue wire, also referred to as the neutral wire, has the function of transferring electricity away from the appliance. The brown wire, otherwise known as the live wire, transfers electricity to the appliance. The green and yellow wire is also referred to as the earth wire and has a key safety function.
Are brown wires positive or negative?

Is brown electrical wire live?
The earth wire will be green and yellow (or sometimes bare in old systems). The live wire is brown in new systems and red in old systems. The neutral wire is blue in new systems and black in old systems.
What do wire colors mean?
Electrical wiring comes in one of several colors: Black Wires – when you see a black wire, always assume it’s live. Blue Wires – always assume they are live if you have power. Blue wires are also fed through a conduit, usually bringing power to three or four-way switches. Green Wires – green wires are grounding wires.
Does black wire go to blue or brown?
Answered by Dave, Electrical Safety Expert The live Red becomes Brown. The Neutral Black becomes Blue.
Which wire is hot black or brown?
The wiring convention is black for hot, white for neutral and red for other such as a common terminal on a two-way switch arrangement (two switches control one light or outlet).
What is the brown wire in a light switch?
The brown wire is Live (also know as permanent live), this brings the live supply to the switch. The blue wire is known as the Switched Live and takes power to the light. Switched Live is only live when the switch is on (this is where it gets its name from).

Why is active brown?
Brown = Live As previously mentioned, the brown wire has the function of carrying electricity to the appliance. There will be a risk of electrocution if the brown wire is live and not connected to the earth or neutral wires.
What Colour wire goes to L and N?
The N is for the neutral side or the white wire, and the L is for the load side, the black wire.
What are the color codes for electrical wires?
U.S. Electrical Wiring Color Codes Phase 1 – Black. Phase 2 – Red. Phase 3 – Blue. Neutral – White. Ground – Green, Green with Yellow Stripe, or Bare Wire.
What color wire is hot?

Which wire is positive blue or brown?
And for modern wiring: The active wire (high potential) is coloured brown (used to be red). The neutral wire (low potential) is coloured blue (used to be black). The earth wire is striped green and yellow (used to be only green).
Do brown and black wires go together?
If you do have a fixture using international standards, the good news is that the matching is very easy. Brown is your hot wire so you want to connect that to your building’s black wire. The blue is negative or return, so that will go to white.
What is brown wire in house?

How can you tell if a wire is positive or negative?
If you have a wire where both sides are the same color, which is typically copper, the strand that has a grooved texture is the negative wire. Run your fingers along the wire to determine which side has the ribbing. Feel the other wire which is smooth. This is your positive wire.
