Q:I am a science and engineering, some people think that disk will be hot. I think this is not the case, I think the disk has no effect, the wire is the AC current, inside the two lines of the current direction at any time can be offset each other to produce the electromagnetic effect. I think so, I hope a professional person to make a professional and detailed explanation. More

In fact, Tian Min network set-top box on what TV are the same, the TV only acts as a display of the role.

Q:Do I need to put the foam in the studs where the electrical wiring goes through? This is for Fire codes in MN

I am suprised that they dont just use a fire break in the walls. Simply put, a 2X4 or, 1X4 going horizontal, instead of verticle like studs, so that the flame is blocked from going up into the attic or next floor. (its what we use in Ohio). Its in the same wall cavity as the electrical outlet. I dont know if the foam is flamable or not, as I never had to test it around a fire.(I have it in all the sills of my basement to keep the cold out, and hope I never have a fire down there!) If they require it, then I suggest that you get it. Its only about 5 bucks a can at LOWES, so its not like it will break the bank or something of that nature., and I wouldnt also, think you needed them in the stud holes, sill plate, I can see, as it is the very exit to the top floor or attic. I wish you well. Jesse

Q:I have a back patio light that is obsolete now that I added a covered porch. Could I add an electrical box, attach additional wiring, run it through conduit and ultimately attach it to a ceiling fan in the overhead patio area? (from the point from where the wiring attaches to the original light)

Yes it is , but do not hide the box. you must be able to see and open all boxs after the the job is done.

Q:I had to extend some speaker wires, so i used a second speaker cord and wrapped it to the one out the speaker, but the exposed section doesnt look to safe, and it runs behind my bed so i`m a little unsure about it being uncovered. Can i use duct tape just to cover the open wires? or is electrical tape NEEDED? It is plugged into the wall, not battery powered.

Double shrink tube is best.

Q:Hi I am installing a pool pump. The pool pump requires a 14 awg and a 15 amp breaker. We have the wires and the breaker but a friend says since we are running it about 80 ft away from the pool it will lose power. What should we do?

If the recent motor is two velocity, is that the way you would be employing it, or in simple terms a million velocity? Your description is insufficient. Is L3 terminal A? Your bare earth cord will connect with the physique someplace, i assume the mains white will bypass to the user-friendly, and the mains black will bypass to the two the motor crimson for best velocity or motor white for low velocity. in case you utilize it twin velocity, a changeover swap could be mandatory, yet why IS it twin velocity?

Q:How many square wires are used for home wires? It is best to have a detailed answer

This question when the two questions . first explain why the wire cut inside why there are many things like gray, because the insulated wire core is PVC insulation, in the course of aging, inside the assistant decomposition, or inside the filling In the use of a long time will become brittle aging into dust, that is, the wire inside the gray is actually due to the aging of the internal material . the copper is very brittle, first copper rod in the production of copper is very brittle High strength, but the toughness is poor, the need for annealing to make copper wire becomes toughness strength becomes low, easy to pull and mass production, if the landlord think this copper wire is very easy to break, you may not be in line with the national standard Or the production process is not in place for annealing, for reference only

Q:Please guess a riddle: a beautiful ride on the wire. (Hit a plant) Rural visible

Frequency converter cable for the variable frequency cable, he is generally 3 +3 core, outside the copper wire braided + copper double shield, it requires the cable has a low transmission impedance, low working capacitance, it has a lot of high magnetic waves, Cable insulation impact is relatively large, relatively high demand for interference interference factors. Frequency conversion cable long distance transmission, the general should be coupled with the reactor. Ordinary cable, the outside can be added according to the need to shield or not, although he can produce electromagnetic waves, but will not produce high harmonics, the insulation requirements of the cable is not high frequency cable, he can be four core, five core. There is no need for a symmetrical structure of the cable.

Q:My family is this year's new cover of the color steel room, used in the old house when they are relatively thin wires, electricity is very normal every month, but a move to a new house when the electricity that month A bit too much, or the same electricity habits or those appliances how the monthly electricity will be so much? Where is the place where there is leakage and our home with a rough relationship between the wire? Just try to use a pen, and some places are 12v some places did not show, please know how to help my friends how to analyze ah? Thank you! More

This feeling a bit 2 ah. Wire tube is a plastic pipe, plastic pipe is not necessarily used as a wire tube ah.

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 wire from the meter to the inside of the house is your responsibility. Working on this wire involves a utility shut-down. You will need an electrician.

Q:I have an electrical switch that controls a recessed light. I need to move the switch, taking down the wall it is on. My questions is, why are there three wires in there? I understand that one of them is for power into the switch, 2nd one for power out to the light not sure what the third one is for? It is almost impossible for me to trace the line as it goes up into the ceiling.

Sounds as though you may have a two way switch to a lamp controlled by another switch in a different location but you don't say colour codes so difficult to be specific
