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. If your intent is to convert a switched outlet to hot at all times in order to control a ceiling fan or light from the existing switch, then you should click here to read my blog post with photos about doing that. There are two switched outlet wiring diagrams further below that depict split outlet wiring. As an Amazon Associate I earn from qualifying purchases.Īlternatively it is possible to have a split outlet where one half of the outlet is switched and the other half is live at all times. NOTE: Some text links below go to applicable products on Amazon. Generally speaking the outlet would get wired the same as if it were a light fixture. There are a few methods for wiring switched and half switched outlets. Electrician: Where do I find switched outlet wiring diagrams?Īnswer: Switched outlet wiring diagrams are below.
