Q:How do they differ from residential wiring?

Commercial and industrial wiring make extensive use of conduit, cable trays/ This entails explosion-proof or flame-proof fittings, along with the seals and other conduit fittings. Residential wiring, in most cases make extensive use of romex cables without any conduit. Other than these major and a few minor differences, the wiring is actually the same. This is the installation of cables/wires from the circuit breakers to the users. TexMav

Q:Both wires are black. One has what looks like white paint on it.

correct.....both can be hot, as they may have been cris crossed from point to point. the best is to get a volt meter and test to your water pipe if its grounded and not eroded away over the years. problem with using an inductance tester is it may give an erroneous reading if they have been cris crossed. note.....once you find the hot of the two, the other bing the neitral will have a current on it that can be fatal, remember there is no ground to protect you, and if your in water or touching something metallic, you may be the ground path needed to complete the circuit. be careful!

Q:Does anyone know where i can buy them? I need new ones because my crazy cat chewed up two of the wires lol =#92;

Hey there, That is unfortunate and I am quite sure that catfood is cheaper than speak cables these days. What you are looking for is standard speaker cables found in most sorted retailers. Try your local supermarket or electronics store.

Q:I am replacing my old electric oven with a new one. The wires on the old oven are the same as the wires on the new oven...white, red, black, and a bare wire. The wires running from the fuse box to the junction box are...white, black, and bare wire. This is 220/240 wiring from the fuse box. The oven does require 220/240. How do I wire the new oven?

You cannot do it legally.Someone may have done it before.Hooked up white from the oven and the bare to the bare of the fuse box. Is it a cable that runs from the panel to the stove or conduit ? Does it have a little slack ? It may be that it is a legitimate 3 wire cable and the red may have been cut .By skinning the cable back ,you may discover the red wire,possibly. If there are only the black .white and bare wires in the cable running it cannot be hooked up legally to the stove ? How far is it from the panel? That is the best we can give you for now.We need more info. You may have to bring a new 3 wire and bare cable from the panel.install a 50A stove receptacle on the wall. It is rare to see a new stove without a stove cord.It should come with the stove.

Q:I have a set of pilot wi-200 strobe lights and they have three wires and i want to hook them up to a optx headlight strobe control module the wires are gray white and black can you tell me where to hook them

I wouldn't try it. The gray, white, and black wires are the high voltage strobe wires. The control module changes the patterns before the voltage is increased. There is nothing you can do here.

Q:I just purchased a Pyle Audio aftermarket radio. The wiring is very different actually. It only has 2 single speaker wires (1for each side). So do I hook up multiple wires to one wire or what? I was thinking that I hook up the left front and rear speakers to the left speaker wire and vice versa for the other side. Need some advice.

Wow. I haven't seen a car stereo with that style of wiring in 20 years. Their is no manual online so I am going to assume that it is setup the same as stereos made in the 1980's. You are correct, both left speaker positives go to the left channel wire and the same for the right side. All four speaker negatives go to the ground wire. That means a total of six wires being connected together ( ground from stereo, ground from car, four speaker negatives ).and the red goes to full time battery power. The pics I have seen do not show a yellow memory wire, so you will have to remember to turn the stereo off when you get out of the car. Or it will play til it runs the battery down. Also, you didn't say what kind of car you have, but if it's a modern car with fuel injection and a ECM, I would bet you are going to have ignition noise problems. It's one of the many reasons people stopped using common ground car stereos.

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

Yeah...(If you download right now we will send you a bunch of spyware and virus' for absolutley nothing.*) *Note Lime Wire is not responsable for any damage that my occur to your computer as a result of downloading MP3s from Lime Wire.

Q:My house is currently wired using Cat-5 lines. If I were to replace the Cat-5 wiring with Cat-6 wiring, would I see an increase in my DSL speed?

you have to have speical equipment to use cat-6, so no if you did that it would still be the same as using cat-6

Q:How doI wire a ceiling chain light to wall switch? I want to stop using the chain to turn the light on and off. I hane already installed the wall switch and the wiring in the box but not sure how to connect the wiring in the box to the ceiling light wiring.

Before you do anything, turn off the power. Sometimes people will wire up switches hot, but they know what to touch and what not to touch. You should not take that risk. There will be two power cables coming into the box, one from the power source and the other to the ceiling light. Each cable has a black wire, a white wire, and a bare copper wire. Connect all the white wires together with a wire nut. Connect all the bare wires and an extra piece of bare wire together with another wire nut. Connect the extra piece of bare wire to the green screw terminal on the switch. Connect the black wire from the power source to one brass screw terminal on the switch. It doesn't matter which one you use. Connect the black wire from the ceiling light to the other brass screw terminal on the switch. Don't screw the switch into its box yet. Turn the power back on. Test the switch, being careful not to touch any wires while doing so. After it works, turn the power off again and screw the switch into t

Q:I'm just wondering would i be able to connect a split 8 gauge wire with wire nuts like i'll explain:Use two wire nuts instead of one and divide the copper wire on both ends and wire nut both sides together with 2 nuts. The whole apparatus would look kinda like this:----lt;gt;---- with the wire nuts connecting the two arrow thingsThanks anyone

Even though you had been wise to make use of the noalox, or antioxidant, i might ratehr endorse that you get the suitable gauge of wire in copper and rewire the entire circuit. The intent that I say that's that your oven is a excessive resistance circuit and aluminum does no longer like high resistance. With excessive resistance on aluminum, the aluminum wire will start running or moving under the strain and can eventually burn out the connection. In the event you have got to leave it aluminum, don't use a wire nut, but get a split nut from an electrical provide, use teh same goop on it, then get two wrenches for the best way that you just ought to screw the break up bolt to the nut, tighten the item down as tight as humanly viable, the wrap it with a specified tape that the electrical give may also have. It's not the commonplace electrical tape, but a stretchable tape and also you wrap it tight at the least 3 or a bit of extra inches on all sides of the nut. This may insulate the connection in order that it are not able to be shorted out in any respect. Mine had the same aluminum connection and when I changed the stove, which was difficult wired to the stove, I simply replaced the entire wire. Mainly the field is just not too some distance away fromthe stove due to the fact it wants to be as just about it to decrease resistance. To scan what you have got performed, that you would be able to take a low-cost volt meter from Radio shack, set it on the correct settings for measuring voltage on 220, and if the needle goes to 220 + or - a bit, you're nice in the meanwhile.
