- Q: What is the use of Fence baebed wire?
- Cattle.etc...would push on the fence to eat the taller grass on the other side, The barbs change their mind...Also hog wire gives and stretches, barb wire doesn't. A cow would eventually ruin, and walk through, a hog wire fence that didn't have barb wire at the top and bottom edges.
- Q: ceiling fan connections which wire goes where?
- Red on a ceiling fan is hot, and the blue is hot for the lights on it, which will be attached with the red..NOW....the wires on the light box your going to put it in...if this house is in usa, the black wire will be hot, the white wire is a nuetral, and the bare copper is the ground..the green wire on your fan will attach to the bare copper
- Q: Theirs a green ground wire, a white neutral wire and for some reason 3 black wires.
- If the ceiling fan has three speeds, those would be wired to a 3 position switch as low, medium and high. Normally the wires would be labeled if they use the same color. If they aren't tagged, and you want to put in a speed control switch, you'll need to experiment; either at the fixture, or just wire them down to the wall switch and make your temporary connections there to see which wires go with which speeds (then TAG them!).
- Q: I spliced the stereo wires to the adapter to plug into my car. there's 2 extra orange wires in the adapter. There orange it says there for illumination and the dimmer. What should I do with them? Did I get the wrong one?
- Those two wires are useless. Usually I have 3 wires left over. Illumination, dimmer and a blue antenna wire. Your good to go.
- Q: Why do two parallel wires carrying currents in opposite directions repel each other?
- Each wire produces a circular magnetic field. In essence, each wire is carrying current through the other's magnetic field and so the motor effect occurs.The fields are travelling in the same direction between the two wires so like two N poles of a magnet they repel each other.
- Q: siting on a roof and the wire is running into the house, what if you touch it?
- is the other wire grounded or not?
- Q: I am replacing an old outlet with a GFCI and I have encountered a red wire...what is the red wire for?
- How To Connect Gfci Outlet
- Q: True or False?Branch wiring from a 200A - 3 phase 4 wire panelboard.WIRE #PHASES 1 --- PHASE A 2 --- PHASE B 3 --- PHASE C 4 --- NEUTRAL - WHITE WIRE 5 --- PHASE A 6 --- PHASE B 7 --- PHASE C 8 --- NEUTRAL 9 --- GROUNDTOTAL OF 9 WIRES GOING TO SIX (6) 20A 120V CIRCUITS
- That's true. 9 wires may go to 6 circuits. Each circuit has one phase so 1,2,3,5,6,7 are the six phases going to six circuits. For two pair of three phases (pair one 1,2,3)(pair two 5,6,7) there are two neutral wires and one common earth wire. that is total nine wires. there is nothing wrong in it.
- Q: I am wiring a GFCI receptacle with two regular receptacles after it.So before the GFCI I have my 12/2 wire from where it will hook into the box (the line side), after it I have my wire going to the two other receptacles (the load side).Well the GFCI receptacle has screw terminals for the line HOT and WHITE wires as well as a GROUND. On the bottom it has screw terminals for the load side but ONLY the HOT and WHITE, no ground screw.Does this mean that I don't hook up the ground for the load wire or does it mean I have to pigtail the ground to the same screw the line ground is using?I didn't want to assume that I connect the line and load grounds out of fear I was circumventing the GFCI.
- The grounds all are attached to the same ground screw, twist all of the ground wires together and bring one wire to the screw. There are ground wire nuts, green with a hole in the end, put one of the ground wires through the hole and then twist all of the others under the nut.
- Q: Has anyone ever used welding wire in their car audio setup?Is it more flexible or less than other car power wire? Is this a big problem?Is it a good or bad jacket?Would you use it again?I am looking at buying some welding wire from weldingsupply because it is .81 per foot. I would love to know if anyone has done this before and what they thought. The wire i am looking at is 4 gague.
- First off- it is cheaper than audio power wire, you can buy it as thick as 3 ought, I've seen it used. But flexibility is a big deal when hiding power wire, at least I think so, and welding wire is not the most flexible but it is better than solid wire, and power currant runs faster through audio power wire because of the small cooper strands that make up the wire. Than in welding wire because it has thicker and not as many strands that make up the wire, currant will run slower. Will any wire work? yes........ go to a smaller local audio dealer and ask the owner for info
