When I was checking my unfinished basement I found two very long wires being folded/tied and left between joists by the builder/electrician. What are they and how to find what are they for? Each wire is (both are white 14 gauge) at least 15 feet long. They do not have power on to them, so not connected anywhere. Wires are closer to the walls and going into the walls towards the first floor. Any one has any idea?
I put in extra circuits quite often. They could have been for an option on the home that was not purchased with a speculation /track home (homes being built prior to purchased) it is cheaper when you hire a roping crew (they just pull wire based on the generic blueprints) then the electrician goes in and connects everything. If you don’t buy the upgrades they are not connected in the service panel. So they may be spares for additional lighting and or receptacles. Ask your builder to be sure but this will be the most likely answer. Don’t cut them off if you decide to use them in the future having them can save hundreds dollars for each circuit.
Thanks all for the helpful answers.
Since, I posted this question, I found that one wire (pic 2) is attached to the living room outlet and was live all this time and just hanging there. I disconnected it at the outlet but could not pull it out. May be because of the clips and so on. Another wire was also left (discovered after this post) live but pinned to the joists and disconnected that too. The long one (pic 1) probably for the dishwasher and located directly below the DW. There are no outlets behind the DW. We usually plug it into one of the kitchen outlets. Its not live. I'm thinking of cutting them off.
