Q:how do i connect ignition wire from fuse box to cd player?

your wanting to run a wire from your cd player to the fuse box?, ok, take a piece of covered wire, hook it to the hot wire of your cd player, run it down to the fuse that says radio, it should play on accessories and while your driving.

Q:I need to wire a single 120v outlet from the 240v volt wire I use on my compressor. Im installing a 120v electric automatic drain valve on my large shop air compressor. The compressor is wired up with SJ00W 10-AWG, 4-wire power cable (red,green,black white wires). and is rated at 240v @ 15-amp(compressor not wire). The drain valve uses a normal house hold current wiring config. (black,white and open copper)The 240v power supply is the only supply I have near by, (two of them actually) Or I would just wire the automatic valve off an outlet and call it a day. So How do I wire a 120v 3-wire set up from the 240v 4-wire supply? Thanks

Hud is correct. To accomplish this you would need to install a 30 amp subpanel with a 4 to 6 circuit configuration with a two pole breaker for feeding the compressor with # 10 wire and a one-pole 15 or 20 amp breaker with smaller wire (14 or 12 gauge respectively and the appropriate rated 120 volt outlet on that branch circuit). If you have regular 120 volt outlets somewhere nearby (as I think you are saying in your second to last sentence) I would go that route instead.

Q:Why do two parallel wires carrying currents in opposite directions repel each other?

Each of the wires is under the influence of the circular magnetic field produced by the other wire. If you apply Fleming's left hand rule, you will realise that the mechanical force experienced by each wire under the influence of the magnetic field of the other is in opposite direction. So, as the mechanical force on each wire pulls it apart from the other wire, there is repulsion between the two wires. Was this helpful?

Q:Steel wire or iron wire. spool of wire used mainly in the iron frame of the building foundation..

Steel wire is used to brace beams and columns as well as to reinforce concrete (rods are also used to reinforce concrete). This is because steel wire has a high tensile strength and is flexible. These two properties make steel wire suitable for suspension bridges and for winding elevators (lifts).

Q:There are 3 wires where the old floodlight used to be and only 2 wires attached to the floodlight I want to install. How can I tell which wires connect to which... and what is the third wire?

Usually there is a black wire (hot), a white wire (neutral), and a green or bare wire (ground)... in an ideal world:) If you need to find the hot wire, you can get a non contact voltage finder from lowes or the hardware store. This device will tell you where the AC voltage source is coming from without you even touching the wire. You will need to remove the old light and wire nut the wires. Then turn the electricity back on, use the detector to find out which wire is hot. Connect the black wire on the lamp to the hot wire.

Q:i need an egr wiring Diagram for a 2000 Chevy Malibu. the wires got pulled out of the weather tight connector. if anyone can help i'd appreciate

Connector view for the GM linear EGR valve are as follows: Pin# A=gray/w black wire,Pin# B=solid black wire,Pin# C=brown/w white wire,Pin# D=brown/w white wire(see note) and Pin# E=solid red wire! NOTE since pin C+D have the same color wire the correct wire must be identified by checking the voltage with the KOEO (key on engine off) the right brown/w white wire should have a 5volt reference voltage with the key on engine off! Hope this helps.

Q:how do I wire the generator so it can spin 360 on the pole with out snapping the wires.... Thanks

You need some ring contacts and brushes that will be touching those rings that will be spinning while the generator does to complete a circuit without twisting wires. Make sure you get the right size rings and wire for the amount of current

Q:I bought a new light that holds two light bulbs for my bathroom and quickly took off the old light. I then noticed that wall had three wires coming from it, a black, red, and white. The light however has four wires coming from it, 2 whites and 2 blacks. How do i wire this properly so both light bulbs can be turned on and off simultaneously?

cut the red wire i wonder if its like a spy movie u don't cut the light Colors or the dark ones either so cut the red 1!!!! it will be funny i u get eletricuted

Q:Why is thin strand wire better for powering car audio?

Thin strand wire is more flexible and so stands up to the flexing and vibration in a car application better. May not be an issue in the short term, but over time the thinner strand should hold up better

Q:Can I run a 10 gauge 2 wire plus ground from a double pole 30 amp breaker to a dryer that uses 240v? I need to know if the one black wire will be sufficient or if i need to get a 2 hot one neutral wire.

No you need two hot and a neutral your element needs 240 volts.
