We're in the process of remodeling our kitchen and removing soffits around the perimeter of the room. I've opened up a portion of it above our cooktop and refrigerator and wanted to get some advice on how to proceed. As you can see, there are several NM cables that are on various circuits. These wires need to be routed above through the joists.
When I splice the wires, is it recommended or required to have separate junction boxes for each cable?
