We are building a new two-story house. Framing is done but dry wall is not yet done. The next step is to wire all the rooms on both floors with Cat 6 cable. From what I have read in the forum, the use of conduit is recommended. However, when I brought it up to our general contractor he told us that conduit is only done in a commercial unit but not in a residential unit because of the multiple turns and corners in the house. Is he pulling my legs and should I insist on him using conduits?
