Electrical Wiring for a Dimmer Switch
Wiring a Dimmer: I’ve run power using a 12/2 cable to a combination GFCI Outlet and Light Switch.
- From there I’ve run 12/3 wire over to a dimmer. From the dimmer I’ve connected 3 recessed lights.
- The GFCI reset switch pops and I can run an electric tool from the outlet but I can’t seem to figure out the combination to send the power through the switch to the dimmer and to the lights.
- The dimmer is two pole. I thought that was my first problem – trying to wire a single pole dimmer – but I can’t figure out the two pole dimmer either.
- I’m using the correct bulbs (another problem I encountered in the past).
- This is a new house so no drywall or insulation is in the way and yes, it’s mine. Thanks in advance for any advice.
Additional Comments: I like the website. I’ve used your advice many times in wiring my new home and I’ll probably be back many more!
Thank you for the great advice and information! Dave.

Wiring a Dimmer Switch
- 3 Way Dimmer Switch wiring diagrams to help you wire a single or 3-way dimmer switch.
- Don’t get confused with dimmer switch wiring. As mentioned, a double pole dimmer switch is really a 3way dimmer switch, which is wired the same as a standard 3-way toggle switch.
- If you are replacing a standard single switch that is not a 3way switch with a dimmer, then you may notice that most all dimmer switches are now pre-wired to be used as either a single dimmer switch or a 3way dimmer switch.
- When wiring the dimmer as a single switch one wire will be capped off and not used. Detailed information and wiring diagrams that will help you out and get your lights shining bright.
