How do you determine the white and black wire if they are not marked?
If you are talking about lamp cord that table lamps use, look for a raised rib on one of the parallel wires. This is the identified wire so it will be connected to the neutral (silver) blade of the plug.
What to do with the white wire in track light with black green and white wires if the house does not have a white one?
The white is neutral. The house does have a neutral wire even though it may be black. One of those black wires is the neutral and the other is the hot wire. You will have to determine which is hot and which is neutral. You can easily do this with a voltage tester. The wire that lights the tester is the hot. When you wire the light simply wire the hot to hot, and the… Read More
Any marking (a white stripe, bump molded into the cable, different wire colours) is an indication for your reference only. It doesn't matter, as long as you connect the marked side on the amplifier to the same polarity on the speaker side. Read More
most dryer cords are flat and the connection on the dryer is split or the ground wire connection will be at a different height. The cord probably has black, red, and white wire. Black and red are hot and white is ground. It does not matter black and red or red and black, they are both hot. If the dryer is not marked it will be layed out so that the ground will be the… Read More
Yes. But the white wire can also be a hot or switch leg if marked correctly. But for the most part white is netural. Read More

If both wires for a ceiling light fixture are black how do you tell which is the live wire and which is neutral?
If both wires are black, the one that connects to your white wire is the one that should have little writing on it. Black to the plain black wire, white to the wire with writing. Read More
When installing a Y shaped electric range plug and it has places for three wires and you have a black wire white wire and a bare copper wire so which wire goes where?
Usually the bottom leg is the ground. It should be marked as such with a g or the universal ground symbol, which is stacked dashes that get smaller from top to bottom. In this instance the white and black are both power legs and go to the two angled legs. Use your meter to verify this. Read More

In some cases in residential wiring you do. From a light fixture junction box to a switch box, the cable is a two wire, black and white. To connect the switch into the circuit at the fixture box, the "hot" conductor is connected to the white wire that goes down to the switch. The switched "hot" comes back on the black wire and this is then connected to the fixtures black wire. The white (neutral)… Read More

What wires match up on a ceiling fan where ceiling has black white red and fan has black blue white?
Black to Black - Black from the ceiling is a hot wire and should be switched Red to Blue - Red wire is another hot wire and should also be switched White to White - White from the ceiling is the neutral and should not be switched. Your wall should have two switches, one will control the red wire, one will control the black wire. If you wire your fan as above, one switch will… Read More
How do you install a ceiling fan that has green black blue and white wires to a junction box that only has black white and bare wire?
Connect the green wire to the bare wire in the junction box. Connect the white wire to the white wire in the junction box. Connect the black blue wires to the black wire in the junction box. The black is usually the fan and the blue is usually the light on the fan. They seperate them in case you wish to hook the fan/light to two switches. Read More

If the outlet box is metal, attach a 4inch bare copper wire too the copper wire with a ground wire nut (has hole through top of nut) now attach to a green ground screw on the box and to the green screw on the… Read More
Black would be hot, white would be hot, and green would be common. Four wire is usually two hots, a common and a chasis ground. Just make sure you don't connect one of the service hot wires to the green wire. So, if you are wiring this to service with black, red, white, and green (bare) wires, you connect black to black, and green to green. The white wire of the cooktop connects to the… Read More

It will have 2 black or brown wires. Look very closely at the wires coming from the light. One of the wires will have ridges on it or may have a white line or some other method of identification. That wire is the neutral wire and connects to the white wire in the ceiling box. The smooth wire is the hot wire and connects to the black wire in the ceiling box. Read More
At the lights there is a black, white and bare wire from the supply. With power off you would break the black (Hot) connection at wirenut. Then you just need to run a wire to and from the switch.

How do you install a dimmer switch black wire black wire and green wire to some existing black white wire?
Sounds like you are are installing a single pole switch (your load is controlled from one location only). If your existing switch is hooked up to a black and a white wire you are dealing with a switch loop and that white wire is being used as a hot wire. Make sure the circuit breaker is off of course, and hook up the black wires on your dimmer to the existing black and white wires… Read More
