120v receptacle wiring diagram

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.

What wire goes where on a receptacle?

White (neutral) goes on the side allocated for the larger prong. Black (Hot) goes on the smaller prong side or white to silver screws, black to gold screws. Ground (bare wire) to green.

Which wire goes to which prong?

A polarized plug will have one prong wider than the other, which is the neutral, and usually silver-colored prong. The hot prong will be narrower and usually gold colored. With a non-polarized plug, you can wire either wire to either prong.

Does it matter if you wire top or bottom of outlet?

It's up to you, there is no standard electric outlet orientation. So that means there really is no such thing as upside down outlets. One way isn't safer than the other — as long as the outlet is wired correctly. It all comes down to aesthetics, so install them whatever way looks best to you.

How do you tell which side of a receptacle is hot?

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.

Is the wide prong hot or neutral?

The wide prong on the plug links the threaded base of light bulbs to the neutral terminal (the wider slot) in the receptacle. The hot side of the outlet (the side that can deliver a shock) is wired to the threaded socket if the wires are reversed.

What happens if you wire an outlet backwards?

Reverse polarity outlets will still provide electricity to lamps, appliances, and other items. Saltzman says electrical equipment will continue to function and won't be damaged by the incorrect wiring. However, you might be more susceptible to a shock.

What color wire goes where on a plug?

The power cord has a white wire, green wire, and a black wire. The white wire is connected to the silver or light colored screw, the green wire is connected to the green screw and the black wire is connected to the gold or dark colored screw.

Does the hot wire go on the top or bottom of a switch?

Does a hot wire go on top or bottom of a light switch? It doesn't matter. Switches simply break (off), or complete (on), circuits so that current can flow or not. Sort of like a drawbridge: If it is open (switch is off) the cars (electrons) can't cross.

Which prong is hot on a 3 prong plug?

What wires go on a three prong plug? The left slot is "neutral" and the associated white wire should be connected to the silver screw. The right slot is "hot" and the associated black wire should be connected to the brass screw.

What color wires go to a 110 plug?

To wire a 110 volt/120 volt outlet, you need 3 wires, green or bare copper is the ground, white is neutral, and usually black or red is the hot (live) wire (in this case my Hot is the purple wire). In the home, you will usually use Romex wire that you can get at the hardware store.

How do you wire a 110v outlet?

Pull the sheathing off and expose the bare wire. Make little hooks on the ends of the wires and wrap them around the electrical terminals. The black hot wire goes to the gold terminal, the white neutral wire goes to the silver terminal and the green or bare copper ground wire goes to the green colored terminal.

Why do electricians install outlets upside down?

Electricians may position the outlet in an upside-down position so that you can quickly identify the switch-controlled receptacle. Since it stands out visually to most people right away – it provides convenience to the occupants to easily remember which outlet is switch controlled.

Is it code to install outlets upside down?

In reality, there is no code requirement that says an outlet receptacle should be installed one way or the other. In fact, at one time some manufacturers actually recommended the orientation that many of us view as upside down—with the round grounding slot at the top.

Why are there 2 sets of wires in one outlet?

So, why are there two black and two white wires in your outlet box? There are two black and two white wires in an outlet box because the outlet is in the middle of a series circuit, accepting power from another source and sending it on. Two cables are hot wires, bringing the power in and carrying it onward to the next.

Which terminal is hot on an outlet?

Outlets, or receptacles, typically have two brass-colored screw terminals and two silver-colored terminals. The brass terminals are for the hot wires, and the silver terminals are for the neutral wires.

Is black wire hot or neutral?

Hot wire is identified by its black casing. This is the main color of hot wire for most homes. However, other hot wires can red, blue, or yellow, although these colors can indicate a different function besides powering an outlet.

Which wire is neutral when both are same color?

In most modern fixtures the neutral wire will be white and the hot wire is red or black. In some types of fixtures, both wires will be the same color.

Is the smooth or ribbed wire hot?

The ribbed side of the line cord indicates the neutral wire, the smooth side, the hot wire. If we are wiring a line cord plug, the ribbed wire would connect to the wider space or neutral space on the plug itself.

How do I know which wire is hot and neutral?

The hot wire is always smooth on the outside of the cord, while the neutral wire is ribbed on the outside. For flat cords with polarized plugs on the end, the larger prong (or terminal) is the neutral wire.
