Is it safe for the time being to leave a loose black electrical wire from my doorbell transformer? (I think this is the transformer based on what I have read)
I tried to push the box into the wall and it didn't quite stay and a wire I think came loose. I think this is a hot wire but I am unsure and do not want to touch it. Is there any issue with leaving this exposed until I can get someone to check it out? The doorbell no longer works so I'm guessing this is the power to it.
I believe it came out of the red cover which has the other black wires.
