We had a under cabinet kitchen fixture that needed to be replaced. When I installed the new one the wires would not reach. I tried to get the wires from the wall to pull out a little further but there was no slack. So I took the ground & hot wire from the previous fixture & spliced it to the corresponding wire to make it reach. I used a few wire connectors & electrical tape to secure each wire. The fixture works fine. Is the house going to burn down later? I assume that is all an electrician would have done.
