In my house, I fortunately have a well-labeled circuit breaker. There are a few rooms that could be better named, but it's fine.
As such, it's very easy to identify almost every switch and what it does and what breaker switch it's attached to.
Except for one light switch at the entry way of my house.
I turned it on and stuck a voltage tester next to it. I went through every single breaker switch, even the ones for other floors, and the voltage tester continued beeping. I skipped the doubles (washer, dryer, and HVAC), because I assume a light switch wouldn't be connected with a major appliance.
I've also tried plugging a light into various outlets and turning the wall switch off and on, but I don't see any change in the light.
The voltage tester only stopped beeping once I turned off power to the entire house. So as far as I can tell, this switch seems to do nothing.
- Is there another method I can use to trace what this switch connects to?
- What should I do with this switch?
Update: I have finally figured out where this mystery switch goes to: an outside outlet. I never even noticed it until y'all pointed it out so thank you! I still don't know which breaker it goes to, which is annoying but I've got at least half the mystery solved
Update 2: I have found it! Once I realized it went outside and was GFCI, I guessed that the cable was connected to the Basement GFCI circuit and that did it. Personally I would have labeled it "basement + outside gfci" or wired it to the first floor outlets or put it on a separate breaker but it's fine. I'm not bitter at all
