Q: All the other outlets in the room have one black and one white wire. The outlet with 2 is not connected to a switch or anything. Could the extra set of wires be and end run from a different connection? Can I take the extra black and extra white from the bottom tabs of the outlet and extend it behind the kneewall into the hallway and make a new outlet? I have none in the hallway and I've always wanted one there. Thanks.: one pair of wires is power going in to the outlet, and the other pair is power going out. to add an outlet in to your hallway, add a third wire by tieing all the blacks together, and all the whites together with wire nuts. dont forget to add a small jumper wire of each color to power the outlet you are working on. make sure the white wire is connected to the same side the copper ground wires are connected to. if you dont have a copper ground wire, attach the black wire to the side with brass colored screws, and the white wires to the silver colored screws

Q: I am installing a high-hat. I had hoped to run it to another light switch at the top of my stairs. That light switch is currently connected to another light in the ceiling of my den. The problem I have is that the den light is also controlled by a swiutch at the bottom of the stairs. PROBLEM : When I ran my HIGHHAT wiring ot the top switch the box only had 3 wires (a red, white and black). I wasn't expecting this. If I wanted to use the poswer in this box, and add another switch, what should I do? The Black and White were on one side of the old lightswitch and the Red was on the left.How would YOU do this? Can it be done without adding another live wire into the box?Basically, I need ot know how to add another light/switch using hte red black and white.: You cannot do this without some re-wiring. From the description, you are trying to go to a 3-way switch. It sounds like it was wired as a dead end. There is no neutral wire at this switch. Therefore, it is not possible to wire your light directly into this switch box. You may be able to run new wiring that would make this possible. However, we would need a lot more info about your existing wiring to advise.

Q: Hello.I switched over from a gas dryer to an electrical dryer in our home. I ran 10/3 wire from a dp 30A breaker to a 4-wire recaptacle for the dryer.When I turn on the dryer, she spins but no heat.When I checked the outlet, each hot wire to neutral gets 120 volts but between the two hot wires I do not get 240. I then went to the breaker and checked there. Once again 120 from each of the hot wires to neutral, but no 240 volt reading from one hot wire to another. What would be the problem?In fact, when I check any two hot wires on the breaker I do not get 240 volts. Why? I tried swapping out the 30 amp breaker for another one in the event that it was faulty, but alas, still no 240 volts.: Check across the bus bar (where the breaker plugs in to the panel) see if it has 240 volts. This is the bar that the breaker plugs in to. If you do not have 240 volts across this then check the line side of the main breaker (where the wires terminate at) see if you have 240 volts across this. If you have 240 on the wires that attach to the main and do not have 240 across the bus bar you have a bad main breaker not giving you 240 volts. You may try to re set it and see if that does the trick. If you check the line side if the main and do not get 240 volts then you should cal an electrician Hope this helps

Q: If electrical wires were built underground then there would never be any outages from storms. I'm sure they thought of this and there's a reason why, I just wanna kno what's the reason?: Why aren't telephone and electrical wires built underground? They are in the U.K. And Europe. And Australia, And Japan. And South America. And China. And India. And Canada. And just about every other civilised country on the planet.

Q: I remember dialing a short 3 digit number to fix a pothole in my neighborhood (although I can't remember the number). I was wondering if there was another one I can call that could fix this buzzing' noise caused by an electrical wire by my house that's quite annoying and a bit skeptical whether I should be alarmed by it or not. Appreciate it. :): In most cities it's 311. I believe it is in Los Angeles as well. However, the electrical lines are probably owned by your power company and my guess is that you'll have to contact them with any concerns you have or to get them fixed.

Q: I notice that theyre usually associated with two poles: Both the hot and the neutral comprise the circuit for a 120 volt circuit. In a 240 volt circuit, the two hot wires carry current and the neutral doesn't, unless the device has both 120 and 240 volt devices associated with the main device. The above statement is relative to the USA normal household service. This service is a split-phase service from the secondary of a 120/240 volt system. The neutral (center tap of the secondary) is grounded. The neutral is a conductor just as the hot wires are. The hot wires are designated 'hot' because they are not grounded. If you touch one of the hot wires while simultaneously touching something that's grounded (including yourself), you will receive an electrical shock, sometimes resulting in death. The neutral, being grounded, will see a volt or two potential difference between the neutral and ground. This is more pronounced, if the circuit is carrying a load. If the load in your home is completely balanced on both hot wires, the neutral will carry no current between the circuit breaker panel and the transformer. The neutral and the hot wire of a circuit changes polarity 120 times per second. TexMav

Q: Why the wire cut there are many ash, and the copper wire is very easy to break: Do not know what you mean, if only from the literal point of view and understanding, the bridge should be installed in the top of the pipe, the top of the heating tube.

Q: I just bought a house, and the area where the dryer needs to go only has a two foot electrical wire coming out of the wall. It's an old house, and it's possible these people just hooked those wires directly to the dryer without using an outlet. Is that possible? Or do I need to install those wires into a three prong outlet for electrical supply to my dryer?Thanks!: It would depend on your areas electrical code if it was legal to do that or not. I cannot see why in a residential setting anyone would need to do that. If I were you I would call an electrician to check the wires and install a proper outlet.

Q: Ten five hundred twenty two, five five five four three circles, seeking to explain more specific meaning: Dedicated line is the dedicated line of electricity users. Is the user's own property rights, their own maintenance, while power supply has a high reliability. Non-green is relatively speaking, is hanging in a lot of users are using a bus on the same time. Non-green line is not caused by the substation, from the nearest capacity to meet the needs of the 10KV line attracted.
