Ive just moved into a 95' home and attempted to replace the hood over the range with a microwave. I disconnected the hood, cut an opening for
the box and was attempting to install the box when i realized that the drywall was broken open enough and i couldnt lock the paddles in place to secure the box. I called a friend who had recently done this and he told me to screw a drywall screw through the box into the side of the
2x4 behind the wall. when i did this the threads on the screw frayed the insulation to either the range or hood wire that was stapled to the
2x4. Im not sure which one and there doesnt appear to be any damage to the wire itself. Is there any repair i can make to this or will i have to rip everything out to replace the wire? Please Help!
