Q:How do I wire low voltage T-Stat with 5 wire ?
depends on the t stat look at the back for a better idea the wires should be collor coaded 2 for the heat and 2 more for the ac and maby 1 for a ground
Q:Welding wire in car?
i did almost 15 years ago it was ship and i like the wire the problem was engine noise for 3 months and i refuse to believe it was on a simple cable but once i replace it with 4 gauge normal inexpensive wire the noise was solve not a good idea
Q:How do I connect a threaded wire with a naked solid copper ground wire with a wire nut?
spin the stranded wire between your fingers, this will make it more rigid. if you dont you'll end up winding the stranded fan wire around the solid wire and it will just slide out of the wire nut when you push the wires back into the box ( and you might not notice it until you put the whole fan together and mounted then flip the switch and nothing happens.) if you have two wires put them together and nut them, if you have three it's best to twist them together then nut them. they usually dont give you enough pre-stripped wire on the fan leads so you have to strip about another half inch off to make a decent connection
Q:Why when you loop a straight wire into loops (coil), it acquires a higher inductance?
Imagine two closely spaced parallel wires. If you run a current through one, it creates a magnetic field that induces current into the second wire, which causes an even stronger magnetic field. Now if you run the same current through both wires, they both create magnetic fields that affect each other. Any two loops in the wire are just like two parallel wires with the same current, both creating magnetic fields that affect each other. So a loop is like a bunch of parallel wires affecting each other.
Q:Attention installers of cable TV, main electrical wires, telephone wires...?
Depending on the size of the hole, you should be able to fill it with silicone sealer. If it's brick you will need to get the mortar type. If it's a big hole you may need a lot more repair than what we can go over here.
Q:how to wire an emergency residential boiler switch?
Hello there George, It has become common over the past few years that non-residential boilers are wired with EPO (emergency, power off) switches just outside each door to the boiler room. This is similar to having fire alarm pull boxes by the exits. I do not know of any jurisdiction that requires it for a residence. On occassion I've seen the 24 volt circuit for the thermostat being switched, which is a bit sketchy. Normally the 120 volt circuit for the controller is switched. The switches used are of the pushbutton type.

Q:Stereo speaker wire?
yeah thats fine they will work. do suggest some monster speaker cable over that but what you have there in the link will work.
Q:Does burnt wire still let electricity flow?
It would help to know exactly what you're trying to do here. Like Gary said, I'm not sure what you mean by inside those wires they have insulation. I'm trying to guess what you're trying to do here and you say you need to connect some wires. Are you trying to connect two sets of insulated wires together? If so, I'm guessing that you needed to strip the insulation off of the ends of the wires to expose the conductors and connect together? If that's the case, usually we use a wire stripper or a small razor blade to cut the insulator around the wire and then pull off the sheath, leaving clean wire underneath. Burning the insulation off is not going to make copper wire not work (if you oxidized the copper, you'd have to heat it way hotter than a typical flame, and it would not be metal any more--it would be crispy). So if you still have flexible metal left over after burning off the insulation, then you still have a conductor. The problem, and the reason why we don't usually burn off insulation is that you're going to end up with a bunch of burnt up goo and oxides on the surface of your wire which will make it not connect well with another wire surface to surface. You can probably solve this problem by lightly sanding or scratching the burnt parts of the wires. Or just cut off the burnt part and try stripping it with a blade instead. Then make sure to insulate your connection with electrical tape or something so that you don't have bare wires that can touch each other and short out. If you're trying to do something different, please explain more. In general, though, you're not going to ruin copper by burning it, but you will tend to coat the outside of the wire with stuff that doesn't insulate well. You want shiny copper when you are connecting two pieces together.
