I am installing a new range hood. Here is the problem the wire coming from the wall is not long enough to insert into the back of the hood. Can I add a small section of romex to extend the wiring? Can I assume white to white black to black and bare copper to bare copper with wire nuts and electrical tape? If not what do I do? House elecrical is not my thing but think I should be able to extend it by a foot or so. Thoughts comment suggestions welcome.
