Light Switch Wiring Connections
Electrical Question: I just changed a light switch and lost power to my outlets, what did I do wrong?
I just replaced a chandelier in the Dining Room of our home and changed the wall switch to a single pole dimmer switch.
- No problems, everything works fine, However:
- In the adjacent formal living room none of the outlets now work.
- The thing is, the two rooms share the same breaker.
- So I have power to the fixture and outlets in the dining room, but no power to the outlets in the living room.
- I’ve opened and closed the breakers, and all other outlets and light fixtures in the house work fine. Any idea what the problem might be, and how I could fix it?
This Home Electrical wiring question came from: Joe, a Homeowner in Indiana.

Common Light Switch Wiring Problem and Solution
Example of a Switch Wiring Connection Where there is a Outlet on the Same Circuit:
- Be sure to check all the wire connections in the junction box where you just changed the light switch.
- It is very possible that there is a lost connection with a wire.
- Check to see if the outlets are wired through the dimmer switch that was just installed, if so the outlets need to be removed from the Load side of the dimmer switch and connected to the Line side.
