Connect the Receptacle's Neutral and Hot Wires. Because the two silver terminals are interchangeable in normal outlet wiring, the white neutral wire can be connected to any of the two silver terminals. Similarly, the black hot wire can be connected to either brass screw terminal. If you were to connect both wires to different terminals, this would create a short circuit that could cause damage to your home.
The location of wires within an electrical box or fixture does not matter as long as they are separated by at least one inch. The only time this might not be the case is if you were to run two separate circuits into a single-outlet building block and connect them both to the same wire (either black or white). In this case, the rule is to keep each circuit no more than three feet from an outlet to prevent shorts caused by overlapping wires.
Overall, the goal when installing an outlet is to provide a place for people to connect their phones or laptops while keeping electricity away from objects that can lead to fires. There are many ways to go about doing this, but ensuring that wires are kept apart within an outlet is one step toward safe wiring practices.
The "hot" or "live" black wire (or red wire) is linked to the electrical receptacle's brass-colored screw terminal, while the "neutral" white wire is attached to the silver-colored screw terminal. The term "hot" and "neutral" are actually designations used by electricians for the wires in an electrical system. It is very important to distinguish these wires when working with electricity!
If you were to connect one end of a voltmeter to the black wire and another end to the white wire, it would read 120 volts because that is the power being delivered to the receptacle. However, if you wanted to deliver only 40 volts to a load connected to the receptacle, you could do so by connecting both ends of a 20-volt resistor to the black wire.
In other words, the black wire is the hot wire, and the white wire is the neutral wire. You should never connect two devices that require different voltages on either of these wires; doing so will result in damage to one of the devices. If you were to connect a lamp to the black wire and a radio to the white wire, both items would break down due to the voltage being applied to them simultaneously.
Connect the white neutral wire or white pigtail to one of the receptacle's silver (neutral) screw terminals, wrapping the wire clockwise around the screw terminal. The insulation should only come into contact with the screw termination. Do not connect any other wires to the receptacle.
The black hot wire should be connected to one of the green (hot) screw terminals. This terminal will be marked "LOW" or "HIGH". Wrap the black hot wire counter-clockwise around one of these terminals.
If you are replacing an old wiring system with a new one, use the old wiring holes as a reference point when connecting the new wires. This will help prevent confusion later if another part of the house is also being wired for electricity.
The final step is to test your work. Turn off the power at the breaker panel before testing any connections. If all is well, turn on the power again. If anything is wrong with your work, turn it off immediately and fix the problem before turning the power back on.
You have now completed a simple circuit! You can use this same process to connect any number of lights or appliances to one wall outlet. As long as one light or appliance is plugged in, the other(s) will work.
The white (neutral) wire is connected to the silver screw, or it can be inserted into the rear wire hole on the same side of the device as the silver screw. The black (hot) wire is connected to the brass screw or a hole on the rear of the device on the same side as the brass screw. This wire is occasionally red. If it's not present, then the black wire should be assumed to be hot unless there's a reason to think otherwise.
If you're wondering why the white and black wires are always together, it's because they come from one circuit, and whatever connection is made between them will be made inside the panel or elsewhere in the house. These days, most homes have separate circuits for lights and appliances, so they don't have to be kept together.
You should connect all three wires before inserting them into the wall outlet. This ensures that no electricity flows through any of them by accident.
White to silver, silver to brass. Black to brass. It's that simple!
Keep in mind that if you use alternative methods to conduct electricity, such as using metal tape instead of wire, you must also replace any old wiring with new stuff that matches exactly. Otherwise, you might end up with a short circuit.
Checking your work: pull out each wire and look at it closely.
