What is a neutral wire?

A neutral wire allows our switch to be powered while simultaneously allowing the lighting circuit

connected to your lights to be power off.

Do | have neutral wires?

  1. If your house was built in the mid-1980s or later, there is an excellent chance that you have
  2. neutrals everywhere in your home.
  3. If there is an outlet (wall receptacle) near the switch, most likely that switch box has a neutral.
  4. Switches that are ganged together have a much higher likelihood of having neutrals, no matter what year.

Checking the switch box

  1. The best way is to check the actual wires in the switch box where you want to install .
  2. Please observe all safety precautions before handling the electrical wiring in your switch boxes.
  3. Turn off your breaker box.
  4. Take off the trim plate over the switch.
  5. Remove the screws from your switch and pull out the existing switch to look at the wires.
  6. If you see a white wire (or group of them), it is VERY likely that you have a neutral.


The only way to be absolutely sure that you have found a neutral wire is to check the voltage (110V/120V) between the white wire and the “hot” (usually black in color) wire in the box. In a standard switch/dimmer, the “hot” is using one of the two wires connected to the switch.


Please note:

Recommended installation by professional electrician
