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.
Is blue wire positive?
If you are talking about the wiring of buildings/houses then blue would be a hot with ac current. If you mean wire in electronics then it would also "usually" be a positive but if there is any danger you should never assume. A tester could save you from having to buy a new component or your life.AnswerThe European convention is that blue insulation indicates a neutral conductor, brown, black, or grey insulation indicates a line conductor, and a yellow/green striped conductor indicates an earth conductor.
How do you install a ceiling fan to plug into a wall outlet and should you use two or three strand electrical cord and which strand on the cord connects to which fan wires?
The neutral wire will have writing or ribs on it and connects to the white wire. The smooth wire is hot and connects to the black wire. Use 3 strand wire in size AWG # 16. If the fan has a light it will have a blue wire. Connect that blue wire to the black wire.
What is red blue and black wires for?
Answer for USA, Canada and countries running a 60 Hz supply service.Depending on the insulation, these wires can be used for anything except grounds and neutrals. In commercial and industrial settings, black/red/blue are colors usually used for 120/208v 3-phase systems. This is an industry standard, not a code requirement. In homes, black and red are used for each leg of the single phase 120/240v system. But again, this is not a code requirement.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.
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?
Answer for countries in Europe and other world areas running a 50 Hz supply service.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 JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any work ANDalways 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.
What are the different colors of wire, including brown, blue, and green, used for in electrical installations?
Brown wires are typically used for live or hot wires, blue wires are used for neutral wires, and green wires are used for grounding in electrical installations.
Do you attach the red wire to the brown and black to the blue for a light?
No, typically red wires are connected to hot/live wires and black wires are connected to neutral wires. Blue wires are often used for connecting to neutral wires as well. Remember to always follow the wiring instructions provided with your specific light fixture.

What do the stripes indicate on the green and blue wires on a 1992 Ford Festiva radio harness?
speaker wires
What are blue brown and yellow wires?
Blue - Neutral Brown - Life Yellow/Green - Earth
What are the wiring color codes for automotive vehicles?
Wiring color codes are the identification colors that color the wires in your automobile. For example, if you have a British car the blue, blue and white , and blue and red wires are for the headlights. The red and white wires are for the instrument lights, and the green and white and green and red wires are for the turn lights. The color code simply identifies what that wire does. Could you imagine if all of the wires were the same color. You couldn't identify anything in a harness.
What is the color combination of the blue, yellow, and brown wires in the electrical circuit?
The color combination of the blue, yellow, and brown wires in an electrical circuit is typically used for specific purposes, such as blue for neutral, yellow for earth/ground, and brown for live/hot.
How do you take out a car radio?
you take it out by cutting the blue and green wires
What are the blue cables for on video cables?
Blue cables designate one of the three wires for a component video cable connection. Along with the Red and Green wires, these three form a component video cable.
How many wires are contained in an RJ 45 jack?
There are 8 wires, or 4 pairs. That being orange & white orange, green & white green, blue & white blue, brown & white brown.
