I was installing a new bath fan and had it all done. I was cleaning up the wires in the attic and accidentally put a staple through the wire as I was securing it to the lumber. I put some electrical tape around it and seems to be working.
There is not enough slack in the wire for me to cut it at the point where I pierced it. So my question is, do I need to have an electrician come out and replace or repair it, or is the electrical tape a safe solution?
