I ran a 6-3 romex wire from the main electrical panel in the garage up into the rafters then Pvc pipped down the wall and drilled through the concrete into the crawl space Then I supported the wire and drilled into the basement where I drilled holes and ran my wire through the joists over to the position of the kitchen counter top and the new cooktop. Went upstairs and cut a two gang old work box out then drilled to the basement and fished my wires through where I would install a 11 B box for the new whip of the cooktop to be installed I then put a blank plate on the two gang old work box and made my connections in the panel after supporting all the wire throughout my run I labeled the panel and the plate Tested Customer has a 1 year warranty
