Light switch wiring diagram depicting the electrical power from the circuit breaker panel entering the wall switch electrical box and then going to two ceiling lights via a two-conductor cable. The grounding conductor is not shown to simplify the wiring diagram. A three-conductor cable with a grounding conductor is used from the ceiling to send power to a light switch. The photo above depicts the wiring diagram of a ceiling light and light switch with the power from the circuit breaker panel entering the ceiling electrical box. The power enters the ceiling light electrical box and branches off to the single pole wall switch using a three-conductor cable. Diagram of ceiling light to a switch using a three-conductor cable to the switch.

It is essential to follow the electrical code and other building codes for the safety and protection of your home and family. All of article 404 pertains to the installation of switches. This is why the above wiring diagram is not used much anymore. The neutral is needed for electronic dimmers, timers, and WiFi smart home devices that can be installed instead of an ordinary light switch. It is required by the National Electrical Code (NFPA 70) that a neutral conductor be available in each light switch electrical box. You cannot connect a receptacle outlet to this type of switch wiring because there is no neutral wire in the switch box, but you can at the ceiling electrical box, assuming there is enough room for the extra wires. Consequently, it is common to find a white wire in a switch box that is the hot LINE, and the black wire is the switch leg connected to the LOAD. Some electricians use a permanent marker.Īlthough re-identifying a wire is the code requirement, it has not been implemented as much as it should. Re-identifying a wire is done using colored electrical tape. Neutrals are rarely required to be switched. If you see a white wire on a wall switch, it is most likely not a neutral conductor.

However, in most cases, the white wire is not re-identified with another color.

The two-conductor cable from the ceiling box to the light switch should have the white conductor re-identified with another color because it is not being used as a neutral but as a hot wire. The two conductor switch wiring diagram at the top of this post is from older homes and is likely not used much anymore, depending on which code book is in force in each jurisdiction.
