It depends on how you hold the receptacle. White wire goes on the silver screw. Ground wire goes on the green screw. Things are usually the way the are for a reason... Electrical outlets have a larger opening on the neutral (white wire) side and a smaller opening on the hot (black wire) side. That is for a reason.
Which side of the wire is hot on an outlet?
The first side is the “hot” side. This will be denoted by the brass (gold) screw terminals. You’ll notice black is the predominant wire color for hot. But if it’s a switched outlet/receptacle, you might also see red coming into the side. On the other side, you’ll see silver and green.
Where does the neutral wire go on a receptacle?
The white "neutral" wire - this wire is connected to the silver screw on the electrical receptacle, often labeled "neutral" or "white". You can see our white neutral wire connected to a silver screw on the receptacle in our photo.
Where does the ground wire connect to the outlet?
The incoming ground wire is connected to the ground terminal on the electrical receptacle (usually a green screw such as shown in our photo at left). at GROUND WIRE CONNECTIONS.
What color wire goes on the green side of an outlet?
On the other side, you’ll see silver and green. Silver goes to your white or neutral wire, and then your common wire will go to your green. How do you know if you’re dealing with a switched outlet?
What happens if you wire a outlet backwards?
When plugged into an outlet wired incorrectly, reverse polarity can easily damage your electronics. If your electronics do not have any mechanism to protect against reverse polarity built into the circuitry, it is only a matter of time before they are damaged.
Which wire goes to which terminal on an outlet?

Which side of an outlet gets the hot wire?
Looking at the receptacle itself, the hot side is the side of the outlet the thinner prong plugs into. The thin prong is the hot wire, and the thick prong is the neutral wire.
Does the hot wire go on the top or bottom of an outlet?
The black 6" wire will terminate on one of the brass-colored screws, the red one on the other brass screw, and the white one on the silver-colored screw. It is most common to put the red wire on the bottom screw, since that will make the top plug-in "hot" at all times and will be a little easier to plug things into it.
How do you tell which wire is load and which is line?
Load Wire - Generally connected to the top half of your switch. If the wire is coming from the top of the switch box, it is likely your load wire. Line Wire - Generally connected to the bottom half of your switch. In some cases, line wires are marked with “line”, “pwr”, or a lightning bolt symbol.
Which wire is load and which is line?
The line side of an outlet is where you connect the incoming source power. The load side is where the power leaves the device (or electrical box) and travels down the circuit.
Which side of 3 prong outlet is hot?
The high voltage (about 120 volts effective, 60 Hz AC) is supplied to the smaller prong of the standard polarized U.S. receptacle. It is commonly called the "hot wire". If an appliance is plugged into the receptacle, then electric current will flow through the appliance and then back to the wider prong, the neutral.
Which side of an outlet is positive?
Because we use A/C current, prongs don't have have a positive and negative. Instead, the two prongs have a 'hot' and 'neutral' side. The wider prong connects to the neutral wire and the smaller prong smaller prong is the hot side of the circuit.
How do you tell which wire is positive and which is negative?
If you have a wire where both sides are the same color, which is typically copper, the strand that has a grooved texture is the negative wire. Run your fingers along the wire to determine which side has the ribbing. Feel the other wire which is smooth. This is your positive wire.
Does it matter which black wire goes where on a light switch?
It doesn't matter as long as you do it the same on both switches. So, if you connect it to the upper right terminal on one switch, connect it to the upper right terminal on the other switch. Connect the second traveler wire to the terminal opposite the red wire terminal.
How do you tell which wire is positive and which is negative?
If you have a wire where both sides are the same color, which is typically copper, the strand that has a grooved texture is the negative wire. Run your fingers along the wire to determine which side has the ribbing. Feel the other wire which is smooth. This is your positive wire.
What side is positive and negative on an outlet?
Because we use A/C current, prongs don't have have a positive and negative. Instead, the two prongs have a 'hot' and 'neutral' side. The wider prong connects to the neutral wire and the smaller prong smaller prong is the hot side of the circuit.
Where does black and white wire go on outlet?
End-of-Run Outlet Power comes from the service panel along the black (hot) wire through other outlets, switches and light fixtures on the circuit and begins its return to the source through the white (neutral) wire. The black wire attaches to a brass terminal; the white wire, to a silver terminal.
Does the black wire go on the brass screw?
The black wire goes to either the brass screw or the hole in the back of the device. Sometimes this wire is red. The green or bare copper wire can be attached to the green screw terminal on the switch or to the electrical box.
How many hot wires does Rick use?
Rick often electricians run a 3-wire system into a building area using two hot wires and a shared neutral, to permit providing two circuits in an area while having to pull just one wire to the area. But to sort out how your wires were connected and are being used requires some expertise, visual inspection, and testing using a VOM.
Is mis-wired wiring dangerous?
Watch out: mis-wired electrical receptacles are dangerous. Electrical wiring should be performed by a licensed, trained electrician and should comply with the National Electrical Code and local regulations. This article series describes how to choose, locate, and wire an electrical receptacle in a home.
Can you connect a hot wire to ground?
NEVER connect a hot (red or black) wire to ground ( nor to the white neutral wire) - doing so would form a dead short, should trip a breaker, or if not, could cause a fire or could cause a dangerous shock. If there is a hot wire that is not used in a junction box, SOP would be to cap it off with a twist-on connector.
What is the wire called that connects the ground and black wires?
To connect the receptacle with pigtails, each of the black, white, and ground wires in the two cables in the box are joined together with a short length of wire called a pigtail. Normally the pigtail will be a wire with the same color coding as the circuit wires: a black pigtail is hot, a white pigtail is neutral, ...
Why is pigtailing preferred?
Why Pigtailing Is Preferred. One drawback to direct wiring through a receptacle is that the receptacle is in the middle of the circuit and any trouble in the receptacle spells trouble for any devices downstream. Any problem with the receptacle, or even a loose wire under one of the screw terminals, could cause you to lose power to ...
Why is it so hard to diagnose a problem with a direct wiring circuit?
Even diagnosing the problem can be difficult, because if all receptacles lose power, it's hard to determine which one is causing the issue. Direct wiring also complicates repair or replacement, because if you have to take one receptacle out of the circuit, you interrupt the remaining downstream receptacles.
How to direct wire a receptacle?
To direct-wire through the receptacle, connect one of the black hot circuit wires to one of the brass-colored terminals, and connect the other black wire to the other brass terminal. Similarly, each white neutral wire is connected to a silver neutral terminal.
What is the green pigtail on an electrical box?
Usually, this ground terminal is a green screw threaded into the back of the metal box, but it is also acceptable by code to make this connection with a green clip that attaches to the side of the box.
What is a second cable in a circuit?
One cable is the incoming power source entering the box from one side, while a second cable exits the box to continue onward to "downstream" locations on the circuit. (There may also be a third cable if the circuit is branching in two directions at this point.)
Can a pigtail wire be reconnected?
The receptacle must be reconnected before the circuit downstream can function again, leaving the circuit out of commission in the meantime. With pigtail wiring, these drawbacks are eliminated. A problem or loose connection with one receptacle will not affect the receptacles downstream.
How to check if an outlet is really off?
After you shut off the power to the outlet, use a voltage tester to double-check that it’s really off. Insert the tester’s probes into the top two slots on the outlet. If the tester lights up, you toggled the wrong switch on the electrical panel and you’ll have to try again.
What to do if your electrical box isn't grounded?
If your electrical box isn’t grounded, you can still convert to a three-prong, but the replacement must be a ground-fault circuit interrupter, or GFCI (the type of outlet with a red button on its front).
Can you use a two prong plug with a three prong plug?
Without an electrician, it’s safe to convert a two-prong to a three-prong outlet only if the electrical box housing the outlet is metal and the cable feeding the box is armored.
Is it safe to do electrical work yourself?
Simply put, electrical work is dangerous . With projects of any complexity or sophistication, we wholeheartedly recommend hiring a licensed electrician. There are, however, simple repairs and updates that are appropriate for budget-minded do-it-yourselfers ready to proceed with careful attention to detail.
How does a 2 prong plug work?
Actually all electronic and electrical equipment will work with a 2 prong plug inserted backwards into the receptacle. In the case of radios and television sets there may be a slight increase in interference from stray electrical fields (you could say phantom voltage radiating into the air) if the plug is inserted backwards.#N#In modern equipment neither the "hot" nor the "neutral" may be connected to the chassis. Difficulty would be had only if there was a defect inside causing the neutral and the chassis to become bonded and also someone touched an exposed metal part bonded to the chassis or the piece of equipment was connected (say via a coaxial cable) to another piece of equipment whose chassis was grounded.
What happens if you touch the hot side of a lamp?
If you touch the hot side, you will get shocked. Some appliances and table lamps have a " polarized plug", that has a larger prong on the neutral side. You can only plug that in one way. In the case of a lamp, this connects the ring of the socket to the neutral and the center connection to the hot.
Can you replace a two prong receptacle with a three prong receptacle
First of all you can't replace two prong receptacles with three prong when no ground is present. Proper wiring of a receptacle is the black (hot) wire on the gold screw. I don't know if that is left or right. It depends on how you hold the receptacle. White wire goes on the silver screw.
Is it safe to use a multimeter to check if a wire is grounded?
Many things are polarized and having the hot and neutral in the right place keeps things safe. As in the illustration above. Also, a multi-meter is NOT a safe or effective way to check to see if your wiring is grounded. You can very easily get a false positive with some kinds of cable.
