Black is hot and white is neutral. If you are switching something you switch the black, so that is what you would cut.

How do you wire a GFCI if there are 2 black wires?
You will have to run new electrical wire or a single ground wire back to the panel (though the former is highly recommended). A GFCI outlet will cut off the circuit if it senses voltage leaking to ground. If there is no ground wire, it will not function.
How do you bypass a wattage limiter in a ceiling fan?
just did one. Cut the three wires and remove it. Then join the black to the red and the white to the white. Thats all it takes
How do you wire a 110 outlet from a 110 light switch?
I assume that both the light switch and the outlet are already installed. First, look at the visible portion of the switch carefully. Does it say "Off" and "On"? If not, you have a 3-way switch, and you should stop here because these instructions will not work for a 3-way switch. Now, identify all devices that are operated by this switch. Presumably, you at least have an overhead light on the circuit. Identify the breaker that controls this circuit and turn it OFF. Now you need to identify the LAST device on this circuit. To do so, one device at a time, remove each device from its box (but do not disconnect the wires). The last device will have only one cable (sheathed bundle of 3-4 wires) coming into the box (any devices between the switch and the last device will have two cables coming into the box). Now, purchase enough cable to stretch from the last device to the outlet you want connected to the switch. Remember that this cable will have to run across ceiling joists, wall studs, etc., rather than in a straight line. The new cable should be the same gauge and type as the existing wiring. Purchase 3-4 feet more than you need. You will also need wire nuts (the standard yellow nuts is the size you will most likely need, but it won't hurt to buy a variety pack), electrical tape, wire cutters, a utility knife, wire strippers, and cable staples (U-shaped nails) Go to a place where you can access the BACK side of the box that houses the last device on your circuit (if this is an overhead light, that will be in your attic; if it's a wall outlet, you're pretty much screwed.) Punch out an unused hole in the back of this box and feed at least six inches of cable through that hole. Staple the cable to a ceiling joist or other sturdy frame member as close as possible to the box. If you are lucky, there will already be a hole in the top plate, with a different cable running down to the outlet. If not, you're going to have to drill your own hole, and take a chance of electrocuting yourself and/or shorting out your whole house, if there is another cable running along the underside of this top plate. Once the hole is drilled, feed the cable down through that hole as far as you can. Now, identify the circuit that controls the outlet and turn the breaker off. Take the cover plate off of the outlet, then unscrew the outlet from the box and pull it out of the box. Again, you need to identify how many cables are coming into that box. If there is only one cable, disconnect all wires from the outlet and cap them with a small wire nut (grey will probably work best) and tape them up with electrical tape. If there are two cables, you will need to disconnect all wire and match them up - black to black, white to white, ground to ground - and connect each matched pair with yellow wire nuts and tape them up. This will remove the outlet from its previous circuit, and you can now turn that breaker back on. Now comes the hard part. You need to somehow take the cable end you fed down through the top plate and feed it into the back of the outlet box. If the box isn't nailed to a stud, you can just pull it out, and it will be much easier. Otherwise, this task will be be very near impossible. You might try bending a coat hanger straight, then bending the last inch back into a U shape, then trying to fish inside the wall for the cable end. But even if you can catch it, you have to pull it through a small hole in the back of your box, and that cable isn't very flexible. You may end up having to cut a section of your drywall out and replace it later. Once you get the new cable coming into your box, trim the end to 6 inches, then cut the sheathing off with a utility knife, being careful not to cut the insulation around the individual wires. Separate the black, white, and ground wires and strip the last inch or so of insulation from the black and white wires. Bend the last inch of all three wires into a U shape. Hook this U-bend around the connection screws as follows: Black wire to one of the two brass screws on the right side of the outlet, white wire to one of the two silver screws on the left side of the outlet, and ground wire to the green screw at the bottom of the outlet. (It doesn't matter which of the two brass screws or which of the two silver screws you use, as long as the black wire is connected to brass screw and the white wire to a silver screw.) Now go back to the front side (not in your attic) of the box for your overhead light (or whatever you determined to be the last device on your switched circuit. You will have the new cable sticking out of that box, as well as the existing connection from your circuit to the device. These connection will be as follows: one circuit black wire connected to one or more black wires going to the device (if the device is a ceiling fan, and it has a light kit attached, there may also be a blue wire attached to the black wires); one circuit white wire connected to one or more white wires going to the device; and one circuit ground wire connected to a bare or green wire, which in turn is connected to either a metal part of the device or a grounding screw inside the box. You will need to remove the tape and wire nuts from the black wire connection and the white wire connection. Then add the new black wire from your new cable to the existing black (and blue, if applicable) wires and connect them all together with a yellow wire nut. Then add the new white wire from your cable to the existing white wires and connect them all together using a yellow wire nut. Tape up both connections with electrical tape. Then twist the new ground wire around the existing bare ground wire to complete the ground connection. Replace your device, turn the breaker back on, and check everything.
Can a cut electrical wire cause a fire?
If the exposed wire grounds out and a great amount of heat is produced then yes a fire could start under this condition. Remember overhead transmission wires are exposed wires but are well insulated from ground so as not to have the above scenario happen.
How can you cut an energized conductor?
With an insulated handle wire cutter.
Can an extension cord be used if it has a cut in it?
If the cuts depth is just the outer protective covering just tape it with electrical tape and you will be fine. If the cut penetrates the insulation of the underlying conductors on the green or white wire, tape the cut and then tape the outer layer of the protective covering. If the cut penetrates the black wire then it is best to get rid of the cord. If the cut is close to the end on a longer extension cord, cut the end off where the cut is and get a new end from a DIY store. Remember white wire on silver screw, black wire on brass screw and green wire on green screw. Do not use the cord with the cut uninsulated as this could lead to a dangerous situation especially if the cord is used in a damp or wet location.

How do you Connect on and off switch between continuous wire?
First you turn off the power. Then you cut the wire. Strip each end of the cut wire and attach to each side of the switch. This should only be done within a switch enclosure. If there is no extra wire to make a good connection, you can extend the cut ends with wire of the same size as the cut wire and use wire nuts to securely connect the "pigtail" wires. You should only switch the hot side (Black wire in home wiring) and not the white wire which would pose a shock hazard.
Do Black People Get Their Hair Cut By White People?

How do you put a switch into an existing lamp flex?
=== === You can add an on-off switch to the flex if you use a "torpedo" or similar shaped switch that has been designed to be used for this purpose. Here is how to install it into the flex: * unplug the light from the outlet! * open up the casing of the switch * where you want to insert the switch cut the outer cover of cable very carefully with a sharp knife * be careful not to nick any of the other wires * cut one of the wires - especially if there is a black wire, that is the one to cut * if there is no outer cover on the flex then just cut one of the two wires which make up the flex * only cut one wire, don't cut the other wire! Just leave it undisturbed. * on the cut wire strip back the insulation about 5mm on both sides of the cut * connect one side of the cut wire (from the plug) to one terminal of the switch * connect the other side of the cut wire (going to the light) to the other terminal of the switch * NEVER CONNECT ANY WHITE/NEUTRAL WIRE TO THE SWITCH TERMINALS! * Place the other, uncut, wire inside the casing of the switch, lying alongside the switch mechanism itself. If you also want to lengthen the cable then: * you'll need to wire up a plug with a new length of flexible cable containing a pair of BLACK and WHITE wires to plug into the outlet * cut off the existing plug supplied with the light from the end of its cable * wire the "hots" of both of the cables to the switch terminals as described above. * the white/neutral of the flex or cable coming from the new plug to must be joined to the white/neutral wire in the flex going to the light using a proper small connector for electrical wire - it must be small enough to fit safely into the switch casing alongside the switch mechanism without touching either of the switch terminals. (If you know how to use solder safely, you could solder the two neutral wires together.)IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicatorto insure the circuit is, in fact, de-energized.

In black and white meaning-?
When something is in black or white the meaning is that it is the truth.
Why is there only red black and white wire ceiling and no green?
Each color means a different thing and there are green ones, they are just not as common There should be a bare wire along with the red, black and green wires in the ceiling. It is possible that it was cut off short or tied up to the box somewhere. this is the same as the green wire.
Where is the ground wire on 88 Honda Accord that would affect headlamps?
The ground wires are to be found just below the main lights, the ground for the left low beam headlight for example is to the left and above the windshield washer motor. You have to remove the front bumper to get to this area. There are two white electrical harness connectors made of white plastic, each on one side and close to the headlamp assembly. Pull the connectors apart and then check them for looseness or corrosion. It is possibe that a wire leading to one of them is broken. The color of the ground wire is black or white and black in the models that I have information about. Flickering lights indicate a problem of looseness, while no lights indicate either a broken bulb or a cut wire.
2004 venture Inside door lock switch not working?
If its the drivers door lock switch not working, 99 times out of 100 the problem is a corroded/broken splice in the wires. The wires/splice run under the passenger side carpet. Remove the passenger side plastic door-sill plate and pull up the carpet revealing the wire harness. Unwrap the electrical tape, find the solid white wire and solid light-blue wire. On the white and blue wire there is a splice(wrapped in electrical tape) with 2 wires splicing into one wire. You will need to remove the electrical tape and most likely you will find the splice is corroded or completely broken(due to water leaking inside-another story). Cut out the corroded wire and splice in a new piece of wire, wrap in electrical tape and you should be good to go.
How do you replace a bad 3 prong electrical plug with a new one?
if its moulded u have to actually cut the wire and see whether the wire is good or not........ if its good u can purchase the plug with isi mark (or UL) and unscrew it with tester/screwdriwer and fit the wires as follows IN THE USA, for 120 volts, the colors usually seen on cords are GREEN for ground / earthing WHITE for neutral BLACK for hot leg / live wire In other countries it may be other colors such as: Green or the earthing wire black or the neutral wire red or the live wire now accordingly instructions are printed on ur plug........ green wire in the topmost pin red wire in the pin were "L" is mentioned black wire in the pin were "N" is mentioned if ur wire is not in condition please approach a registered electrician for further clarification......gonecase17@rediffmail.com Any electrical supply or even Home Depot will sell you a replacement plug. They're very easy to put on.
