Switch to the unknown


I have a "light switch" in a bathroom....thats "live", but no idea what it is for. I had a electrical guy come in and he was unable to figure out what it is for.

Any ideas on what I can use to figure out what this is for? I have it turned off, I am confused on what it could be for.

Do you know if your bathroom was remodeled?
We've run into instances where a bathroom had been re-done -
they had an over-head light fixture, which was removed -
the lighting was from a "bar" light, over the medicine cabinet.
Whoever remodeled the bath, simply left the switch - dry-walled over the
electrical box in the ceiling.
Do you have other switches in your bath?
What do they control?

Yeah, what "Jay 78" asks.

It could possibly control an outlet. I don't know why they would have a switched outlet in the bathroom but it's possible. I bought my house from a company that "flips" them, and they replaced all of the outlets in the house, well each room had a switched outlet that they didn't consider. Now I'm going through the wiring/outlets to find out which one was switched, very time consuming.

How old is the house?
How big is the bathroom?

Where, relative to the fixtures and door, is the sw located?
How high?

Keep it off until you know what it was INTENDED for.

If you're to the point of thinking it doesn't do anything, I'd disconnect the wires and individually wire nut them (so there was one wire per wire nut, no actual connections.) Put a blank plate on it. Personally, I wouldn't leave it there long term with the switch just off.

Unless you run across something that doesn't work someday, then you're done... And if you don't cut much wire off, or none if you can, then yhou could hook the switch back up easily. Unless you wanted to try to track down where this cable connected to a live cable so you could disconnect it and drywall/plaster up the switch hole.

There is other way which I do from time to time to find where that unknowen conductors run which I do is use the toner and trace it where it end.

Majorty of the time it will be either plasted up junction box or just hanging in the wall cavity with wirenuted or taped up.

That get pretty common when peoples remodel the place and never always properly disconnect the circuit like that.

Merci,
Marc

The bathroom could of been remodeled, but unsure. The bathroom is about 7ft x 5ft enough for sink, shower/bath and and a toilet.

There is a light on top of the sink, but they have their own switch.

The previous owner put up a exhaust fan on exterior wall that needs to be fixed ugh

Not much of an electric guy...

I'd turn the switch off and leave it off, you'll either figure out what it controls or you'll realize it doesn't control anything in which case you're probably better off with it kept off because the other end of the switched hot wire is probably dangling in a wall somewhere...
