I have removed the header in my kitchen and have found six wires that that need to be rerouted. I can easily lengthen most of them and put them in journal boxes between the rafters, but where they pass by the top wall sill plate will be a problem. I will try to drill down through the plate for most of them, but one does not go that direction and will need to be placed on the side of the plate. Is it kosher to notch the plate on the side so the wire fits flush to the wood? Dry wall and my new taller cabinets will go over this wire. Please advise. Thanks.
