Wiring Diagrams for Electrical Receptacle Outlets

Wiring Diagram for a 20-Amp 120-Volt Duplex Receptacle. A 20 amp, 120v duplex receptacle outlet like this should be installed in a circuit using 12 awg cable and a 20 amp circuit breaker. These receptacles are usually found in kitchen wall outlets where two branch circuits are needed to serve small appliances and a refrigerator separately.

Wiring for multiple ground fault circuit interrupters (gfci) and standard duplex receptacles are included with protected and non-protected arrangements. Wiring Multiple Outlets in a Series In this diagram wall outlets are wired in a row using the terminal screws to pass voltage from one receptacle to the next.

If one-half of a duplex outlet is controlled by a wall switch, then the hot tab, and possibly the neutral tab, will be broken off. Or if the top and bottom outlets of a duplex receptacle are powered by two different circuits, the hot tab and possibly the neutral tab will be removed.

How to wire an outlet. Standard outlets are known as duplex receptacles. There are a few options to choose from when you wire an outlet. Most are wired so they are hot at all times but some are wired so they are switched off and on. You can also wire outlets so that only the top or bottom receptacle is hot at all times and the other is switched.

If you are going to install more than a single duplex receptacle in one location I prefer to use the dupelx-receptacle wiring approach described in the article above. Two or more such receptacles can be ganged together in a box provided wiring, circuit ampacity and connections are properly selected and installed.

This is a precaution that alerts anyone using the outlet to the fact that it's a split receptacle and not a conventional duplex receptacle Wiring for a Split Receptacle Fed by a Single Circuit In most cases, the reason for installing a split receptacle is so you can control one of the outlets with a wall switch—which means you have to wire it to a switch.

A standard electrical outlet has two brass terminal screws, two chrome ones and a single ground terminal, which is green. When you wire a single outlet to a live circuit cable, you connect the black wire to one of the brass screws – usually the top one, but it doesn't matter – and the white wire to one of the chrome screws.

Switched split outlet wiring diagram for controlling the half of two duplex electrical receptacles by a wall switch without a neutral conductor. Also shown is the half of the receptacle that is live at all times and the tab that must be cut in order to split the receptacles.

If an outlet (commonly called a receptacle) no longer holds a plug snugly, it should be replaced.The procedure for replacing a duplex (two-outlet) wall receptacle is similar to that of replacing a switch. The only difference is that, depending on where the receptacle is located in the wiring scheme of your house, it may have more wires attached to it than you find attached to a light switch.
