If using a multi-wire circuit there would be no need to cut the neutral tab.Ī multi-wire circuit consists of a three wire cable with two LINES or hot wires and one neutral in addition to an equipment grounding conductor. If there will be two separate circuits, then two neutrals may be required and the neutral tab would need to be cut. No need to cut the tab on the neutral side if the top and bottom of the outlet are on the same circuit. Now a constant hot wire can be attached to one screw and a switched hot wire can go under the other screw. The outlet above has a tab cut out on the hot wire side to make it a split receptacle. A duplex electrical receptacle on its side showing a cut tab. Depicted above is the neutral conductor in the switch box as well as the cut tab location on the receptacle. Outlets are split wired so that the top half of the receptacle is live all of the time and the bottom of the receptacle is controlled by the wall switch. Half switched outlet wiring diagram depicting the electrical power feeding into an electrical receptacle box and then going to a switch and to another receptacle. In the drawings below only the tab on the LINE side of the outlet is cut because the top and bottom are using the same neutral.
Split outlets are standard duplex outlets that have had their tabs cut to separate the top and bottom. The bottom drawing shows how it is usually done. The first one shows the method with the neutral conductor in the switch box. The following two switched outlet wiring diagrams depict how split or half switched outlets can be wired. A two conductor cable is run from the switch box to another duplex receptacle outlet that is also live at all times. A two conductor cable is installed from the switched outlet to feed an outlet that is live at all times. From there a 3 conductor cable is installed to a switched electrical receptacle outlet. In the wiring diagram above a hot and a neutral enter the single pole switch box. Switched outlet diagram with hot and a neutral entering the switch box. The same wiring diagram can be used if the power is instead coming from another outlet and connected to one of the depicted outlets on the end. In the diagram below the power is shown coming from the circuit breaker panel. The single pole switch has a neutral conductor for future electronic controls such as a timer or a WiFi switch. Wiring diagram of a switched electrical receptacle outlet and an unswitched electrical receptacle outlet with the power entering the switched outlet electrical box from the circuit breaker panel.

Article 406.12 gives the details of this code requirement. They prevent things from being inserted into the outlet slots as children are known to do. A non-contact voltage detector is good for checking which wires are hotĪny receptacle outlet that could be accessible by children, including kitchen counter top outlets, must be tamper resistant outlets. Consequently it is not unusual to find that the white wire in a switch box is a LINE and not a neutral conductor. However, it has been my experience when working on older homes that the white wire has almost never had its color changed when being used as the LINE. When using the white wire as a hot or LINE it is required that the white wire be re-identified with a different color. That is an unsafe practice and could be a shock hazard. It has been a common practice among the uninformed to use the equipment grounding conductor as a neutral whenever a neutral is unavailable. I think it is a good idea to include the neutral for a wall switch controlling an outlet anyway because the regular wall switch could still be changed to a smart home device which usually needs a neutral conductor to function. The neutral conductor is required for lights in case the standard wall switch is changed to a smart home device or other type of control such as a timer. Although Article 404.2(C) in the National Electrical Code (NFPA 70) requires that a wall switch controlling a light fixture also has a neutral conductor available, switches controlling outlets are exempt from this requirement. The wiring diagram above shows how switched outlets are often wired. SWITCHED OUTLET WIRING DIAGRAMS Switched outlet wiring diagram depicts the electrical power from the circuit breaker panel entering the switched electrical receptacle outlet box where a two wire cable goes to the switch and another two wire cable feeds power to another outlet that is live at all times.
