Q: I have a house built in 1960 that has what I think is original wiring. It is non-metallic sheathed cable. There are some places (underneath old leaks in the roof) where the outer plastic coating has disintegrated. Is this safe? Is there anything I can do to make it safer?: shell out and get the place inspected for sure. Is it safe? Sounds like it's not very safe. Unless your very hip and savvy or an electrician yourself, have a licensed electrician come and rewire the place. Safety is nothing to play with.

Q: Does an air conditioner require several square wires? How many air conditioning is a tile?: If the original line on the wall is installed with a switch, can not be replaced by a socket, because the switch is the two lines are FireWire. The socket requires a line of fire.

Q: The power of the line from the power of some then the current through the wire voltage will come down? Will this be more costly? Question added: is the wire and the voltage is not more than the cable: There will not be anything, but there are hidden dangers! What is the wire? If the cable is nothing, the jacket line is also better, such as just ordinary BV line security risks on the big! Wire insulation of the appearance of a long time will be aging, cover their poor heat in the cement, will accelerate the aging, and ultimately may break the leakage.

Q: I was just wondering is all electrical high voltage lines including low voltage is isolated to prevent electrical shock.: Electrical wiring are insulated not only to protect you from electrocution, but to keep the currents to the destined directions and not go astray.

Q: I have a electrical wire to my ceiling light. The electrical outlet does not have an on/off switch so i want to put a switch on the wire next to my couch. I dont want a switch on the outlet since its not easily accessible. Is there a switch that can splice the two ends.: I don't understand what you have exactly but if it is a ceiling light with a cord plugged into an outlet why not get a radio remote switch that you can mount anywhere

Q: I notice that theyre usually associated with two poles: Ok from the terminology you use I think you are american I am from the uk so i may use different terms Your hot wire/Live wire is the input to the Appliance and the neutral is the outgoing feed so hot in from the power Company and neutral is the return back to the electric company

Q: A couple of weeks ago the e-brake light and another light in our '89 Toyota Celica came on the dash and started flashing even though the e-brake wasn't on. Then a day or two later my husband was turning a corner and gunned it and when it got to the point where he needed to shift the dash lights and headlights and radio all went out. Everything but the headlights came back on within seconds. Now the e-brake light the other light next to it stay on; the break lights, tail lights, fog lights and turn signals all work, but the headlights won't come on and the radio cuts out when the rpm gauge gets to the point where we need to shift. My husband checked the fuses and none were blown. Is this an electrical or wiring problem or could it be something else?: This sounds like an OBD-II problem. Can you take your car to a shop where they will check the computer for diagnostic fault codes. It may be that you have a faulty relay or something simple like a burned out light bulb.

Q: I am going through an apprenticeship program to become a journeyman but I am also going to school to become an electrical engineer and I was wondering if this apprenticeship program will help me while I am getting my electrical engineering degree, should I consider it as job experience or is it a waste of time? And I would really like to know what is the difference between an electrician and an electrical engineer? Does anyone know of any electric company's that hire interns or have apprenticeships for aspiring electrical engineers?: An electrician is simply a tradesman specializing in electrical wiring of buildings and related equipment. Whereas an electrical engineer can deal with large-scale electrical systems such as power transmission and motor control, or they can work with small-scale electronic systems including computers and integrated circuits. I just think of it like this: Electricians work on house wiring. Electrical engineers wire up gadgets (big or small). Also you don't need to go to college to be an electrician if you can become an apprentice, but you have to get certified to be an engineer.

Q: I have an electrical wire that fried on the outside meter box that leads to the inside. Who is responsible for that me or HOA?: the power company owns the wire that goes into the meter box from the street. They also own the meter and the box. You own the wire from the meter box to your service box. Kabish??

Q: can please any one let me know the meaning of db written on electrical wires: Maybe it's attenuation in signal or data cables, but as an electrician who worked with power, I have never seen this on power cables.
