I have a back patio light that is obsolete now that I added a covered porch. Could I add an electrical box, attach additional wiring, run it through conduit and ultimately attach it to a ceiling fan in the overhead patio area? (from the point from where the wiring attaches to the original light)
Yes it is , but do not hide the box. you must be able to see and open all boxs after the the job is done.
