The neutral is the ground
The neutral is NOT the ground. The ground is defined by a third bare or green wire in some cases. Look in the back of the receptacles junction box. See if the ground wire is bonded to the box but was not long enough to bring it out to the receptacle. With a tester you can check to see if the box is grounded. Place the testers red probe on to the black wire and the black probe on to the electrical box if it is a metallic box. If a voltage is noted, then the box is grounded. When the receptacle is reinstalled the ground will be picked up through the mounting screws. Or you can extend the ground wire at the back of the box and connect it to the green ground screw on the receptacle.

∙ 15y agoAll newer installations have a ground wire (bare) in with the other conductors. eg. 2c #14 with bare ground, 3c # 14 with bare ground. These bare wires are used to ground the boxes that they travel through. In a proper installation, one of the wires should be under the ground screw which is located on the flat bottom of the box. From under the ground screw this wire should be wire nutted together with all the other ground wires in the box. If the fixture is a fluorescent fixture, usually you have to provide a ground wire from the fixture to the group of ground wires in the box.

How do you wire multilple power outlets and light?
Power into the first outlet and out to all other outlets, black to gold and white to silver screw, ground wires to ground screw. From the outlet closest to the light switch run power from that outlet up to the switch box. Run another wire from the switch box up to the light. In the switch box tie all the whites together under a wire nut and push them back into the box. Tie all the ground wires together and connect that to the ground screw on the switch. Connect the 2 black wires you have left to the 2 screws on the switch. Does not matter which if you only have power in and power out to the light.
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.
Why do outlets have two prongs?
Actually they have 3. A round ground, wide neutral, and narrow hot. If it only has 2 it is an old outlet with no ground wire. If that is the case in your home, I highly suggest you connect a jumper wire from the ground screw to the white neutral wire on the silver screw to provide some protection. Do this at every outlet in the home. Replace all the outlets in your home with new ones if they are so old they do not have a ground connection.
Which is the hot wire red or white?
In the US, if you only have a black wire (ungrounded or hot conductor) and a white wire (normally a grounded conductor or neutral) there is not a ground wire. Sometimes the white wire is used as a hot, so each wire would have to be identified. <<<< Electrical work should only be done by a qualified electrician.>>>>
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.

How do you wire a 3 wire exhaust fan to a 4 wire outlet?
The fan is probably a 115 VAC single phase fan and the outlet is probably a 230 VAC "two phase" outlet. The fan would then have the following wires: hot (black), neutral (white), and ground (green). The outlet would then have the following wires: hot #1 (black), hot #2 (red), neutral (white), and ground (green). Pick either of the two hot wires on the outlet and connect the hot wire of the fan to that (ignore the other hot wire on the outlet) and connect the neutral to neutral and ground to ground. If the wire colors are not as I described above you may have something else (e.g. 3-phase) and that would be wired differently, but those systems are usually used only in industrial settings not the home.
What is super effective on electric in Pokemon black and white?
Only ground
You have two white wires and two black wires which one is the ground?
black wire is hot wire .And the white is the common or white is ground. Depends on what your talking about in an outlet or car battery. In a outlet the ground wire is green or bare copper. neutral is red and hot is black (I remember it by hot can kill you so black is death) if I am not mistaken. As for a car battery i think it's the opposite red is hot and black is neutral.
How do you wire a two wire fixture to a three wire outlet?
To wire a two-wire fixture to a three-wire outlet, connect the fixture's black wire to the outlet's black (hot) wire, the fixture's white wire to the outlet's white (neutral) wire, and the fixture's ground wire to the outlet's ground wire or grounding screw. If the outlet has an additional red wire, cap it off with a wire nut as it may not be needed for this connection. Always turn off power before working on electrical wiring.
What color of wires are found on a 120 volt duplex poutlet?
A 120 volt duplex outlet is the main type of outlet for residential outlet system. The wires are typically white and black, and there should only be two of them.
Wiring single toggle switch and outlet with two wire system?
To wire a single toggle switch and outlet with a two-wire system, you will need to connect the hot wire (black) to the brass terminal of the switch. Then connect a short jumper wire from the brass terminal to the brass terminal of the outlet. Connect the neutral wire (white) to the silver terminal of the outlet. Finally, connect the ground wire (green or bare copper) to the green screw on the switch and the green screw on the outlet.
You want to install a new light fixture in your bathroom upon removing the old fixture down you discover there is no grounding wire only a black and white wire and GFCI outlet on the circuit?
If there is no grounding wire present, you can still install the new light fixture using just the black and white wires. Make sure to connect the black wire to the live wire on the fixture and the white wire to the neutral wire. Since there is a GFCI outlet on the circuit, this will provide some level of shock protection in case of any electrical faults.
How do you wire duplex receptacle using14-3 wire Also with 14-2 wire The wires are already ran to 15 amp breakers and capped off. i would like to hook them up. Thank You?
To wire a duplex receptacle using 14-3 wire, connect the black wire to the brass screw (hot), the red wire to the other brass screw (switched hot), the white wire to the silver screw (neutral), and the ground wire to the green screw (ground). For the 14-2 wire, connect the black wire to the brass screw, the white wire to the silver screw, and the ground wire to the green screw. Remember to turn off the power before making any connections and consult a professional if you're unsure.
Do you need a neutral when running a BLK Red and ground from a panel directly to a 240V 4800W 20A heater outlet?
Yes, you don't need a neutral wire for a 240V circuit, but you do need to connect the black (hot) and red (hot) wires to the appropriate terminals on the 240V outlet. Make sure to ground the outlet properly for safety.
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.
In hooking up a 240V Air Conditioner you have four wires but only three on outlet What three go on receptacle Red Black White Copper?
For a 240V with ground outlet you will connect black (hot) to one brass screw, red (hot) to the other brass screw, and bare (ground) to the green screw. Cap white (neutral) with a wire nut. It is for 240/120V appliances. If you don't fully understand this buy a book. This is a very basic question. If you don't understand which wire is which you could make a serious mistake causing fire or death.
