Q:I have a 200 amp main breaker just below my meter, which is mounted on a pole. The neutral wire coming in is run to ground. From this box, I've run 2 cables (1/0) ~80 ft to another box with a 150 amp main breaker. This box is grounded to an 8ft ground rod. I am wondering whether this setup (no neutral wire from meter pole to building) would potentially allow a ground fault without tripping the 200 amp main. For example, if somebody dug into the line with a backhoe? Oh yeah, the cable is in a 3ft deep trench that will be covered. I have an abridged version of the NEC, but I haven't found this particular topic covered. Thanks.

Good job, Amy. I'll bet you didn't post a question here similar to: Waz the difference between nuetral and ground. I nned to now this for my electian exam tomorow.

Q:do you match positives and negatives or positives and positives when wiring a car stereo

Q:I already tried wire cutters, and they just bend it!

Need more information: How thick (heavy) is the wire? What's it used for? What kind of wire cutters are you using? Is it one strand or multiple strands?

Q:currently I have 2 12woofers wired to a single amp with 2 gauge wiring. Will it make a noticable difference if I upgrade the wiring to 0 gauge?

Not.rly. if u have bigger wire yea it will have more power running thro it

Q:On a 1985 Dodge D-250 there are two wires coming off of the starter the thicker off the two goes two the starter the smaller one has been cut up by the battery. I was told the truck was running last week and all they were doing to start it was touching it to the positive post with the other wire but when I do this the starter just clicks. I pulled the starter and had it tested and was told its good and I have power to the cab I.e. lights and all so were does this wire go and what do I need to do to start this thing

Sounds like it may have a temporarily weak battery. Hook it up to a charger overnight or get a jump off someone. If manual transmission, you could try a push start and just let the alternator charge the battery while you drive around.

Q:A wire has resistance 56.8 ohms. If another wire consists of the same material but has twice the length and half the diameter of the first, what is the resistance of the 2nd wire?

The two wires are composed of the same material, so we can concern ourselves solely with their respective dimensions. The second wire has half the diameter of the first, which means a cross section of the second wire has only 1/4th the cross-sectional area of the first wire (the area of a circle being proportional to the square of the diameter). The second wire is also twice as long as the first wire. Since electrical resistance is inversely proportional to the cross-sectional area of the wire and directly proportional to the length of the wire, we must have the resistance of the second wire to be 1/(1/4)*2*56.8 = 4*2*56.8 = 8*56.8 = 454.4 ohms

Q:What do you use to seal up the hole in the OUTSIDE wall where the cable TV and telephone wires and electrical wires all go thru? I want to replace my telephone wire coming in to the house, because I have DSL and it is really slow. I figured it couldn't hurt to replace the 45 year old wire coming in! :D I'm gonna use the best wire I can find (ANY SUGGESTIONS on what kinda wire to get? :D) to go from the telephone box outside to the DSL jack, but I need to no what to use to seal up the outside hole, when I rip out whatever is plugging it up now! :DThanks! ~Cindy! :D

Use Cat 5 wire (sold anywhere that sells computer supplies, or phone wire) this is the same wire that is used for ethernet cables, etc. I would suggest running a wire direct to your dsl jack, and do not put anything else on that circuit. Use only the amount of wire you need... don't leave like 50 feet coiled up under the floor, or behind the wall, hehehe. I use silicone to seal the holes. You can buy it in a small tube at places like Radio Shack, or WalMart. Basically anyplace that sells antenna cables will have these small tubes nearby the wiring. (its the same stuff that you weather seal around outside windows with, but in a smaller tube. If you are going to caulk your windows, you can just use that) Have Fun

Q:Ok, I am having trouble installing a new car radio in my 97' Honda Civic Lx. It's just a basic pioneer cd player.. I matched all the colored wires up and still nothing. My brother had told me something about + - for example do i hook the green stripped wire with a flat green wire? Vice versa.. Help please.. Also If you know of a web site with diagrams?

they make wiring harness adapters where all you do is match the colors and plug them in. yes u do have to match the wires with stripes (i.e. green with stripe to green with stripe) but if you have already done this you may have blown the channels if you have crossed the wrong wires

Q:I recently purchased a 1-wire alternator and I'm not sure what to do with the wire harness that was on my stock alternator. Also not sure what the three wires on it go to. Can anyone experienced in alternator wiring tell me what these wires do and if it is ok to leave them unhooked?

the three wires are prolly alternator turn on one wire for the guage and one random maybe ground or something what you need to do is look at the instructions that came with the 1 wire alternator to see if it needs a turn on lead if so you can check the three wires you have with a meter to see which wires put out twelve volts when the ignition is on this is a turn on/ignition lead then youll wanna find the lead that goes to the guage on the dash and make sure it gets twelve volts so the guage reads the other can be capped off

Q:is there a way to wire an exit sign to a plug for an outlet receptacle?

First off, Aurthur A's answer is composed of several NEC violations; he may be going to electrical hell, if he doesn't shape up. Second, you did not say if this is a required exit sign. If it is, then you will need a licensed electrical contractor to install it; as most jurisdictions will not allow work in anything but the owner's principle dwelling to be done by unlicensed personel.
