Line Tracing

During a remodel I found a line(14/2 w/ground) connected to the supply but I can't figure out what it's for. It goes into the floor joists above. I left it disconnected 2 weeks with no affect and have traced every light and recepticle. Is there any other way to determine where it goes and what it's for?

What do you mean by "connected to the supply"?

What part of the house is it in? What did it connect to? Toward what room does it travel?

Perhaps it connects to something seldom used, seasonal or automatic like attic lights, attic fan, heat tapes, christmas lights, furnace air handling, water softener, or the sump pump.

It was conncected to the power supply comming in to the bathrom along with the lights and fan. It goes up to the ceiling and passes through a joist of the living room floor above. There is nothing in this condo that doesn't work while this wire is disconnected. every receptical, light, switch and smoke detector works.

Is the circuit breaker that powers this circuit in any way labeled, such as might give you a clue as to what might be or have been on this circuit?

Are you sure that you tested everything with this wire disconnected? Intercom? Doorbell? Outside light and/or receptacle? Smoke detectors?Everything?

Is it possible that there was a light or ceiling fan that someone might have removed and improperly covered the box over? (Do any other condos have a light or fan or other electrical device that your condo no longer has?)

You can certainly try an experiment and leave the wire disconnected and see what happens. I would not, however, do this just before you go on vacation or away for an extended period of time. You may very well discover that something no longer works.
