Q:I need to drill into the doorframe which is pre fabricated pressed metal and I don't want to drill into the electrical wires . Is there any chance I could drill into them .: you should have two 2x4s on both sides of the doorway and a header at the top. If you look where your light switches are, they should be four to four and one half Inch from the inside of the door jam. That's where the wires run through the ceiling and from the floor. So the answer is that you can drill as many holes in your door jam as you want.

Q:I am working with electrical currents and I have one battery and one light bulb and one wire. How do I make the light bulb light?: Place the battery on a metal table or sheet upright. Connect one bulb terminal to the positive using the wire and place the bulb such dat the other terminal touches the metallic return. Similar lines to the other answer The basic principle is just providing a common return path, just like a bus bar arrangement

Q:3000W of the electrical use of the wire: If you use copper wire, then within 200 meters within 3 kilowatts with 1.5 square wire is enough if it is aluminum core, then recommended within 100 with 4 square (all require the national standard line) if the distance is large, then a large model

Q:I need to know where the park and ILL wires go on the stock stereo. I am trying to install a kenwood cd player and I have thoses extra and dont know where to put it: Here is the original wiring info for that vehicle and if you've any problems just give me the info that came with your new system and tell me what exactly is the wiring problem if any and I'll gladly help you. Car Radio Battery Constant 12v+ Wire: Red/Blue Car Radio Accessory Switched 12v+ Wire: Red/White Car Radio Ground Wire: Chassis Car Radio Illumination Wire: Black/Yellow Car Stereo Dimmer Wire: Orange Car Stereo Antenna Trigger Wire: N/A Car Stereo Amp Trigger Wire: N/A Car Stereo Amplifier Location: N/A Car Audio Front Speakers Size: N/A Car Audio Front Speakers Location: N/A Left Front Speaker Positive Wire (+): Dark Green Left Front Speaker Negative Wire (-): Blue/Orange Right Front Speaker Positive Wire (+): Violet/White Right Front Speaker Negative Wire (-): Brown/Blue Car Audio Rear Speakers Size: N/A Car Audio Rear Speakers Location: N/A Left Rear Speaker Positive Wire (+): Brown/Yellow Left Rear Speaker Negative Wire (-): Brown/Red Right Rear Speaker Positive Wire (+): Blue/White Right Rear Speaker Negative Wire (-): Blue/Red Hope that helps and best of luck.By the way I've installed countless stereos etc and doing automotive electrical troubling etc for many years now.

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:Cable cable price (how much money a roll)? Own decoration with, and what brand of pipe how much money? More: 4 square copper wire in the 230 --- 300 yuan per 100 meters, 2.5 square copper core line in the 160 --- 200 yuan per 100 meters, look at the region to see the market at that time.

Q:I come across electrical wire connectors often and they are varied.I find it difficult and sometime impossible to remove a wire from a connector without damaging the wire or the connector. Is there anyone who know how to handle these?: Many are single use, is that what you are talking about?

Q:If anyone could answer this and provide a source I would appreciate it.: (Quoted from source): Most homes have two incoming voltages: 120 volts for lighting and appliance circuits and 240 volts for larger air conditioning and electric dryer circuits. When an appliance switch is turned on, electrical current flows through the wire, completing the electrical circuit and causing the appliance to operate. The amount of flowing current is called amperage. Most lighting circuits in the home are 15 amp circuits. Most electric dryers and air conditioners require larger 30 amp circuits. The amount of electrical power needed to make an appliance operate is called wattage and is a function of the amount of current flowing through the wire (amperage), and the pressure in the system (voltage). Mathematically speaking, volts x amps watts. So, if we have a 120 volt system and a 15 amp current, we can flow a maximum of 120 x 15 or 1,800 watts on a typical lighting or appliance circuit. When too many lights or appliances are attached to the electrical system, it will overload and overheat. This can cause the wire insulation to melt and ignite, resulting in an electrical fire. The amount of electrical current flowing through wire is affected by resistance. This is known as ohms. Resistance causes increased heat in the wire. Heat is the byproduct that makes some appliances work, such as an iron, toaster, stove or furnace. Large current faces high resistance when moving through a small wire. This generates lots of heat. That's how an incandescent light bulb works. Resistance through the light filament causes it to heat up which gives off a bright light. Electrical resistance also is affected by the length of a wire. Operating an electrical hedge clipper with a long extension cord increases resistance and might cause the cord to overheat, melt or ignite. The same occurs if too many strands of Christmas lights are connected together.

Q:how long the wires for electrical existence please advise: No, the metal in electrical wire lasts a very long time. The insulation may degrade though. But it's many decades.

Q:My instant electric water heater is 4500 watts need to use the number of square wire electrician said 4 square wire can I see a lot of people say that the 6 square of the job Will you 4 square line can withstand it? Question added: how can we know that the line is the national standard or non-national standard ah line is the original developers to help me installed a 4 square does not know is not how to identify the national standard?: Extension line, plus a pair of joints just fine, and only added the connector will not affect the signal
