Q:What role does the neutral wire play?

An electrical circuit requires at least two wires, whether it be ac or dc. In mains ac, one of the wires is connected to ground for safety. This is called the neutral. So the circuit will still work without the neutral connected to ground but not be so safe. The reason the neutral makes it safer is that a current will flow in the event of a fault on the hot wire and cause the protection (fuse or breaker) to operate.

Q:hey im wiring up a headunit to my L300 van. The factory headunit wasnt there and im having trouble connecting which colour wires to the factory colour wires. if anyone knows which coulours go to what would be much appreciatedcheers.

Hi does anyone knows where the stereo looms connect back to .i.e. fused?

Q:The spark plug wire on my dirt bike needs to be replaced because it was touching the exhaust and it burned through.I was wondering if the ignition coil and spark plug wire are one piece and need to both be replaced or is there someway to disconnect spark plug wire? They spark plug wire doesn't seem to be pluged in, but it seems to be one piece. Does anyone know?

Always give year, make, engine size and model # when asking questions. We need all of that info to give an informed answer. Some are one piece, some are removable.

Q:What does the wire do for braces? What happens if you pull it out and everything else it ok?

The wire is like a train track and the teeth are the cars. Get rid of the track and the cars go off course. Wire is what is putting everything in place.

Q:What type of wire do i need to install a normal inside wall outlet? Do i have to use solid copper wire?

Selecting the wire gauge is the easiest part : AWG 12 for a 20 amp receptacle or AWG 14 for 15 amps. Solid wiring is standard for receptacles ( stranded is used in applications where flexibility during or after installation is required). Where will you take power from? Can the circuit you tap carry the additional load? 3 conductor (L1,L0,Ground) BX is the most desirable for indoor wiring at 120v or220v. Will your receptacle be in a kitchen, a bathroom, or near a good ground? If so it should be a GFCI.Will you be able to identify the the circuit's polarity, and verify ground contiuity? Even with three conductor BX, you will want to be sure to use bushings between the conductors and the rough edges of the BX, and to connect the fittings securely at the junction boxes. The actual details and skills required to install a receptacle take years to learn. Take the time to browse through a how- to book or hire a licensed electrician if you want safe reliable work.

Q:Lime Wire is a software that lets you download songs.

Yes, i had lime wire and i had to delete everything i had ever had on my computer it was a nightmaree.. but then i found Frostwire, its the exact same practicall but its blue.. you know how limewire's green, well iv never had any trouble with Frostwire, so i say its a much better choice ;D x

Q:I had gotten 5 commercial solar cells from siliconsolar. But, I need to know where could I get wires to connect to the solar cells, in order to harness the cells energy.

Q:I want to install a single-pole dimmer switch for a series of 4 pot lights in the same box (double gang) as a kill switch for a receptical already installed. There is a 14-3 wire (b/w/r/g) brigning power into the box from the main, and 14-2 wiring for the dimmer and 14-2 wire for the kill switch. How do I wire this? The single pole dimmer has a ground and two black wires. The switch to kill the receptical has only two brass screws on one side.

Wires that have continual power are called source wires. One of the source wires (any color other than white or green) should be hooked up to one of the brass screws on your kill switch. The other brass screw will have the wire going to the receptacle. NOTE: A switch is used to connect/break the connection of power going to an appliance/fixture. The other source wire will go to one of the black wires on your dimmer switch. The other black wire on the dimmer switch will go to the 4 pot lights as its source, in which we call a switch leg. The ground wire of the dimmer switch is hooked to the ground wire in the box. No white or neutral wires are needed for this...Test the wires first so that you know what wire is for what. Then, make sure you turn off all power so that you don't damage the dimmer switch.

Q:why do screen filters have wires with them?

For Earthing to stop static Electricty, connect the wire to the Casing

Q:I have an old sewing machine without a plug that needs wiring up but it doesn't have the modern wire colours. There's one red wire and one yellow. Does anyone know how to do this?Thanks =]

The red one is the earth wire so should go in the right part by the fuse and the yellow one is neutrol so goes in the top middle bit :) Hope that helps
