Electrical Wire Connections for a Dimmer Switch – Many times it is found that a white wire may be used for a switch leg which will carry current or electricity to the light fixture. If you discover this, make sure to identify the wire as a switched wire. © By: Dave Rongey |
Identifying Dimmer Switch Wiring Connections
[ad#block]Wiring a Dimmer: I am connecting a light fixture to a dimmer switch.
- I have a red wire, black wire, and a white wire coming from the box.
- I have three non colored wires from the fixture labeled GRN, LN, and N.
- What connections should I use to complete this task?

Thanks for your electrical question Garry
Dimmer Switch Wiring Connections
Garry, with a lot of switch wiring, the actual use of the wire should be identified using a voltage tester, and this would help out with your dimmer switch wiring project. There are some designations for wiring that can be easily identified, such as the following:
Typical Electrical Wiring Connections for a Dimmer Switch
- GRN is for the Ground Wire connection.
- LN is for the Line and is typically the Black Wire which is the power source.
- N is for the Neutral or White Wire
Electrical Tip for Dimmer Switch Wiring
- It is best to use a voltage tester to positively identify what the designation is of the wires in the switch box.
- Many times it is found that a white wire may be used for a switch leg which will carry current or electricity to the light fixture.
- If you discover this, make sure to identify the wire as a switched leg or wire by wrapping a piece of electrical tape over the white insulation of the wire.
Generally most new switches come with an explanation for the wires found on the dimmer switch. Typically two wires will be one color, usually red which identifies the traveler wires, and the third wire is typically black. Most all dimmer switches are made to be used for either a single switch or a three way switch, so if you are replacing a single switch then cap off one of the two red traveler wires with a wire connector.
