Q: I am trying to change the electrical box to a ceiling fan box. House built in 1959. 4 wires are in the old box 4 white wires are sodered together from 3 of the wires. And one white and 3 black wires are sodered together. I can't take the box out until I cut the wires. What do I do after that? I have a picture I can send.: Mark the cables so you can reconnect them as before. 3 of those black white pairs are line (power), neutral. One is white-(power to switch), black-return, (controlled pwer from switch). (From your fan, the 'black' goes the that loose black from the switch, the 'white' to that cluster of 3 whites.) DO be aware that a fan hanger box is required to have a lot stronger anchorage to the structure than a simple ceiling light box. (You might be in over your head here.)

Q: What is the phase voltage of the three alternating current lines?: The voltage between each phase line (FireWire) and the neutral line (zero line) in the three-phase AC circuit is called the phase voltage, and its RMS value is expressed by UA, UB, UC. The voltage between the phase lines is the effective value Expressed in UAB, UBC, UCA. Because the three-phase AC power supply of the three coils of the AC voltage phase difference of 120 °, three coils for star connection, the phase voltage is equal to the root of the line voltage 3 times. We usually talk about the voltage is 220 volts, 380 volts, is the three-phase four-wire power supply phase voltage and line voltage. China's daily circuit, the phase voltage is 220V, line voltage is 380V (380 = root number 3 × 220). Engineering, the discussion of three-phase power supply voltage size, usually refers to the power line voltage. Such as three-phase four-wire power supply voltage 380V, refers to the line voltage 380V.

Q: A puppy travel in the desert, found the poles, the results still suffocated, why?: In the manufacturers where the cable is on the number of meters, the retailer's words are, up to give you some preferential prices.

Q: An incoming cable (line) is connected to a standard receptacle with the hot (black) wire attached to the upper screw (brass) and the white (common) wire attached to the lower screw (silver). The outgoing cable (load) is attached to the other two screws in the same manner. In my limited residential experience, the line cable will be attached to opposing screw contacts (upper 2 screws) with the second cable (load) attached to the bottom two contact screws on a standard electrical receptacle. In what conditions would these cable contacts be split like this? I have a short along this circuit somewhere and I am wondering if this is the problem?: Actually that is an illegal wiring of a device in today's electrical field. All white (neutral) must not use a device for continuity. Proper wiring would be pigtailed or wire nutted. If the device fails so does the remainder of the circuit. losing the neutral on an appliance can lead to over voltage and fry the electronic power supply. My next question is do you have a short (breaker trips) or an open (no typical voltage across neutral and hot) And the worst offense of wiring is stabbing the wires in the back of the device. Never do this without a pig tail. The biggest reason trailer houses burn down is due to this huge wiring offense. Other problems you can search for: long nails or screws in walls, child puts long items through the back of the outlet. I have seen broken ground lead from plug shoved through back also. Mice chewing on wires to try and squeeze through holes. Smashed wires from GFCI being put in small metal nail on boxes of old construction. Just to name a few. The only time more then one screw should be used on receptacles is when you break the tab between the screws to split the receptacle.

Q: Is all the electrical add up about 6000 watts or so: 75 square meters of cable diameter should be about 5mm. Cable (electriccable; powercable): usually consists of several or several groups of wires. Safety requirements: When the cables cross each other, the high voltage cable should be under the low voltage cable. If one of the cables is in the range of 1 m before and after the cross-pipe protection or partitioning, the minimum allowable distance is 0.25 m. When the cable is close to or intersecting the heat pipe, the minimum distance between parallel and cross is 0.5m and 0.25m, respectively. When the cable is crossed with the railway or road, the pipe should be protected from the rail or the road 2m. The distance between the cable and the foundation of the building shall be such that the cable is buried outside the building; the cable shall be pipe-protected and the protective pipe shall be outside the building. Directly buried in the ground between the cable and the grounding of the grounding device should be separated between 0.25 ~ 0.5m; buried directly in the underground cable buried depth, generally should not be less than 0.7m, and should be buried in the frozen soil layer.

Q: How to prevent the wire from catching fire: . in the cable when it is necessary to use the appropriate specifications of the wire, the diameter of some of the best copper . do not use too much power of the electrical appliances, so that the wire overload operation . the installation of leakage protection switch can effectively prevent short circuit Causing fire

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: I am adding a new outlet and switch and my existing wire in the wall is about a foot short. Can I splice another foot if wire to that to make it long enough?: If you can snake the wire through, you should be able to splice into the receptacle box up through the switch to the light. Don't see a reason to come back down to another receptacle as this will connect it in parallel with the circuit. Make sure you secure the power to those boxes for safety's sake though!!!

Q: A white substance, I'm now worried that this is asbestos, Hope someone can tell me wether it is used in electrical wire, I.E copper based. Please help.: Asbestos has not been used to insulate electrical wire for at about 75 years now. If you are rehabbing a toaster from the 1920's, you might come across it, otherwise the white stuff is probably PVC plastic. If it is fibrous, as in a water heater element, then it is probably rock wool, or more likely: fiberglass - none of which are asbestos.

Q: Hi, I am building a greenhouse in my backyard and had a few questions as to how i should wire it. The appliances I will have in the greenhouse include.A 400 watt light.a 115 volt pump, an oscillating fanand a ventilation fanI can't remember the wattage of the two fans. But my question is will I need to run more than one wire out to my greenhouse? The wire I have says its max voltage is 600. any tips and advice would be nice.: Many extension cords particularly are not rated for out of doors exposure. you're able to get away with it, yet a bigger way could be to purchase some form UF romex. probably 14-2 with floor would be ok for what you're doing. placed a plug on each and every end and Voila! you have an out of doors twine.
