Q: Install the socket wire is black and green to how to correspond. Rush!: This is not an accurate answer, because the thickness of the blinds used in different aluminum, corners of different ways, very different.

Q: First off, I apologize for my ignorance; I'm new at this. Does electrical wire (12 gauge for example), come as a single wire? For example, if I'm installing a 20A outlet 40 feet away from the breaker, do I need 40 or 80 feet of 12 gauge wire?It is my understanding that each outlet needs a (+) and (-) wire, as well as a grounding wire. Is this correct?Thanks for your help!: The most common wiring system these days is 'Romex' cable which is a plastic jacketed assembly of two current carrying insulated wires and a bare ground. There is a lot that you'd need to know about how that cable may be routed through a structure, and how it needs to be anchored to the structure and terminated at it's ends to even come up with the actual length of it you will need, let alone make a safe installation though. There are good home wiring manuals available, and I strongly suggest that you don't even touch any power wiring without reading one.

Q: The total power of six kilowatts need to install the number of square wires: See you specifically what electrical appliances to take what is, 1 ? BV line can be connected to 3 kilowatts, but have to take into account the voltage and start the current, please add detailed friends ~

Q: I am putting in a RV pad and I need a 30amp electrical service what Gage of wire do I need it will be aprox 200' run maybe a little less: HVAC Tech.: While 10ga wire would likely handle the load you will be much safer with an 8ga Multi stran, because of the distance involved.

Q: Does anyone know what the voltage means on electrical wire sheathing? Some 14AWG wires show 600V and others are 800V.I have a burnt wire that shows 1000V.They are all 14AWG, stranded, copper wire. I just don't know what the voltage rating means. Does the wire support up to that many volts or does the sheath resist heat better the higher the number is?: The voltage shown is the maximum that the insulation can handle. Different types and thicknesses can handle different voltages before failing. Wires are burnt by current, not voltage.

Q: I am installing electrical wiring to an 8x12 portable building. I would like to have about five 110 outlets. One outlet will run a 5,000 btu ac. The other will run a small refrigerator. Can I run all this will a single 110 breaker?: Wiring A Shed For Electricity

Q: What is the maximum current through the eight square copper wires: Eight square copper wire through the maximum current is about 40 ~ 80A or so. General normal current by a square 5A or so selected, and the maximum value of about 10A. The smaller the cross-sectional area, the current density can be slightly larger; the larger the cross-sectional area, the current density decreased slightly. Cable carrying capacity: cable carrying capacity refers to a cable line in the transmission of electricity through the amount of current. In the case of thermal stability, when the cable conductor to achieve long-term allowable operating temperature of the cable carrying capacity, known as the cable long-term allowable carrying capacity. Current estimation formulas: 2.5 points multiplied by nine, go up by a straight walk. Thirty-five by 3.. both groups of five points. Conditions have changed, high temperature Jiujiang copper upgrade. Piercing the number of two hundred thirty-four, eight seven six fold full load.

Q: I need to know a SAFE SIMPLE way to run the electrical wiring for an HHO system into my 1985 Chevy Scottsdale. I don't want to incorporate manual on/off switches in the dash. I just want it to turn on when the truck is running, and off when the truck is not in operation. The unit has 4 hex bolts that need to be connected to power source, presumably 2 + 2-I think. I've heard of incorporating the alternator into the wiring. I've heard of splicing power into a unit that only is operable when vehicle is on, such as radio or windshield wiper motor. I've heard of using relays, and some sort of automatic switch that turns on when power is supplied to it, and off when the power ceases to come into it. I've heard things about PWM's and more.I just don't know what I'd need, what some of those things do, or how to hook them up. ANYONE WITH ELECTRICAL KNOWLEDGE /OR HHO INSTALATION KNOWLEDGE.PLEASE HELP. Thank you!: What's an HHO?

Q: hi. i have old westinghouse garage door electrical engine. I would like to make a winch but dont know how to hook it up. it has capacitor and 5 wires. brown brown white blue red. please give me some ideas how to hook it up. thx.: I will take a look and edit this post. Remember these motors are usually intermittant duty so they overheat quickly. The caps are rated at 20 starts an hour. White is neutral. Red and blue are to the cap and are the rotation wires.

Q: First of all, I need to know if this is a fire hazard, how it happened, and how to fix it:A couple of hours ago, a wall socket in the kitchen with an air-freshener plugged into it suddenly made a popping sound. My b/f went in there to see where the sound had come from. It was that wall socket. It had started to make a loud buzzing sound. He pulled the air-freshener from the plug and the sound stopped, but most of the lights in the apartment went out, also, my computer, the refrigerator, the A/C, only a few sockets were left working.Then, by some fluke, he asked me as I was standing in the kitchen if the stove was on. It wasn't, but I started to turn on one of the burners. As I did so, all the lights, my compurter, the A/C, etc all came back on! I turned the burner back off and everything stayed on! This is true and very strange and frightening, as we were afraid of an electrical fire from wiring gone haywire or something.: If you have an electric stove, that may be the source of the problem, if it is gas, then there is no connection. I would have an electrician check things out. This is a potential fire hazard.
