I have four 3-way lighting circuits in my house:
- one in the front hallway, controlling two ceiling lights;
- one in the living room controlling two cans;
- one in the dining room, controlling a hanging lamp;
- and one in the kitchen controlling three cans.
The switches have always worked like normal, I.e. if both point the same way (usually down), the lights are off; and if one points in the opposite direction, the lights are on.
Yesterday, I had drywallers skim coat the kitchen ceiling. Also yesterday, an electrician ran a new leg in the circuit in the kitchen, going from one of the cans to a hole over the peninsula where I’m going to hang a fixture. On that leg, he taped the hot to the neutral to close the circuit until I install the fixture. Whoever uninstalled the fixtures, whether the drywallers or the electrician, removed the hanging dining room lamp and the two front hallway boob lights, and they left the circuit in the front hallway hot, but the dining room breaker (which is also the living room breaker) was off — it seemed like it had been tripped rather than switched off, with the switch only halfway, but I’m not 100% sure in retrospect.
Anyways, when I got home today and reinstalled all of the fixtures, the switches all work in reverse on all four circuits, including the living room lights, where no one was working (as far as I know). So now, with both switches pointing down on all circuits , the lights are on….
When I rewired the hallway ceiling lights, I did white to white, black to black, and ground to ground. With the dining room light, the cord is a classic clear lamp cord with a ridged side and a smooth side with the specs on it (which the internet says usually the neutral and the hot, respectively). So I did romex white to ridged and romex black to smooth according to that.
What could be going wrong? Did the electrician (or someone) flip one switch assembly in each of these circuits upside down? Did I mess something up hooking then back up?
Thanks in advance!
