Q:Is it possible for a wire to arc with a nail? The u-nail that hangs the wire to a wooden support beam looks like it was hammered in too far and may have cut through the insulation around the wire. Is this a fire hazard or can I leave it as is?

Hello, anytime the insulation is broken on the line it can be a potential fire hazard, and yes they can arc or short out. The potential may not be large but with fire it safer to err on the side of caution. Codes vary around the country so check there, but we typically pull the staple and determine how deeply the insulation is really compromised, if it is only through the external shielding an in-expensive way to safely repair it is with a shrink tube type of product. However, if any of the internal strands have been compromised the line would need to be cut and a junction box installed and the wire spliced back together inside the box. Hope this helps:-)

Q:The wire is size 10AWG and will be to install a small fluorescent light in a closet. It is coming off of a typical electric outlet. I know someone who is witing it with commercial wire and I think it may be dangerous. Is it?

If wired properly, it would be much less dangerous than if wired with 16 or 18 gauge wire. The bigger the diameter of the wire, the more less the wire heats up and the less the chance of the wire overheating.

Q:During a lab experiment, a straight piece of copper wire is connected across the terminals of an AC generator and the current through the wire was measured. If the wire is removed and a part of it is tightly wound into a loop of many coils and the wire is then reconnected to the generator, will the measured current through the wire be greater, lesser, or the same as it was before the wire was coiled? Explain your answer.

bypass to the factors save and get a Chilton's! That way you're becoming photos appropriate in front of you to adventure up your application. They value approximately $15! the remarkable $15 you will ever spend. appropriate now you will have all your wires back on and not dropping time top right here with idiots which will greater suitable valuable than probable supply you the incorrect answer as nicely!

Q:01 F350 that did not come factory with cab lights.Bought the recon cab lights that come with its own harness. No plugs on the ends, just plain wires on the end. Where does the green wire splice in to behind the passenger kick panel?

If okorder it will give you a complete wiring diagram of you entire truck.

Q:Two long straight parallel wires are 12 cm apart. Wire A carries 2.5 A current. Wire B's current is 3.7 A in t?Two long straight parallel wires are 12 cm apart. Wire A carries 2.5 A current. Wire B's current is 3.7 A in the same direction.1) Determine the magnetic field magnitude due to wire A at the position of wire BB = ? T2) Determine the magnetic field due to wire B at the position of wire A.B = ? T3) Are these two magnetic fields equal and opposite? Why or why not?4) Determine the force on wire A due to wire B, and the force on wire B due to wire A.

(1) wire-A B = (uo)(I) / (2pi * r) B = (1.26E-6)(2.5) / (2pi * 0.12) B = 4.17E-6

Q:I wanted to ask, im busy installing a new stereo headset for my car,when i replaced the old stereo with the new one, i used the wire harness from the old stereo and joint the wires to the back of new the stereo (which there is another black adapter that goes in the wire harness area on the the new stereo) i did this by connecting the wires from the stereo adapter to the wire harness that connects to the car, although the adapter that connects to the stereo has more wires than the wire harness that connects to the car,( i only connected the wires that were matching such as grey wire to grey wire, grey wire with black strip to grey wire with black strip, and so on, i obviously didn't connect the colours that didn't match to the wire harness wires, although i looked up online and apparently the yellow wire is a power wire, but i don't know where to connect it......if anyone could help, this would be greatly appreciated , i also wanted to ask, would this solve the problem if i buy a new wire harness? Thanks

What kind of car is it? That's important, especially if it's a foreign make because those wires are so weird colored. Typically, yellow or ornage is power, red is memory, and the purple, gray, white, green wires are for the speakers .Black or brown wires are ground. Any blue wires you might come across are mainly just auxiliary signal wires that go to an aftermarket amp and subwoofer setup. Unless you have something like that, those wires can be taped off and forgotten about. Also, when wiring an aftermarket radio to your car, you will need to purchase an adapter harness that plugs into the stock wiring of the car and the wires connect to the radio wire harness correspondingly. I suggest soldering all the necessary wires and sealing them with shrink tube. It's the most solid, most sure way of a good connection without the worry of shorts and disconnections.

Q:I have a Hunter 5 minute fan. I have four wires coming from my ceiling. Red, Black, White, and Bare Copper. The Fan has a Green Wire, Black Wire, White WIre,and a Black/White striped Wire. The Ceiling Plate also has green wire. I know to connect the black to black, red to black/white striped, white to white. But for the green and copper wires, do I connect the copper wire from the ceiling to the green wire in the ceiling plate and also to the green wire from the fan?

As typical color coding goes in 110/120 volt A/C; Black = hot lead White = neutral Green = ground In house wiring the ground is typically bare and has no coating. Typically the fan and the mounting plate will have green wires to ground out the fan and the electrical box. If you have a ground wire (bare copper wire) you should hook to there. Update - - - Curtis is right, below this post. Your box is not set for a ground. Being that old of a house there is no telling what mods have been done. The neutral (white) and the ground (green or bare copper) are the same but different. The ground goes to the ground at your house. The neutral is the return to source (generating station). The ground helps make the electricity go the path of least resistance as soon as possible in the case of a short.

Q:I need to use quot;insulated copper wireor quot;enamel covered copper wirefor a project...I used normal copper wire and obviously it failed. Can this be like normal copper wire with plastic/rubber coating around it, similar to electrical wire? Or is it something special?

yes if it has plastic on it, it is an insulated wire
